Program Scope and Objectives

  1. Purpose. This IRM section describes the formal process for implementing the requirements of the Configuration Management (CM) process. It provides an operational definition of the major components of the process and the requirements for each of the process components. This document also describes the logical arrangements of steps that are essential to successfully completing the process and achieving its desirable outcome. Configuration Management is a systems engineering process for establishing and maintaining consistency of the software product’s performance, functional, and physical attributes with its requirements, design, and operational information ensuring consistency among physical and logical assets in an operational environment. Configuration Management is also one of the components in the Information Technology (IT) Service Support under the IT Infrastructure Library (ITIL) framework. It is an IT Service Management (ITSM) process and its primary goal is to identify, maintain, and verify information on IT configuration assets, or configuration items, in a configuration management database (CMDB) that is required to deliver an IT service. It covers the identification, recording, and reporting of IT components, including their versions, constituent components and relationships. Items that should be under the control of Configuration Management include hardware, software, and associated documentation. Additionally, where IT security and IT operations meet is where it blends together the key practices and establishes a security-focused Configuration Management (called Secure Configuration Management (SecCM)), such as vulnerability assessment, remediation and configuration assessment. For the purposes of this document, the process scope and objective for this Configuration Management is primarily based on supporting the software development and operations environment. Secure Configuration Management process and requirements are documented in IRM 10.8.1 Information Technology (IT) Security, Policy and Guidance.

  2. Audience. The Configuration Management process is applicable to all IT organizations, contractors, and other stakeholders having responsibility for configuration, management, oversight, and successful day-to-day operations of the IRS IT enterprise hardware, software, and applicable documentation.

  1. Information systems are typically dynamic, causing the system state to change frequently because of upgrades to hardware, software, or modifications to the surrounding environment in which a system resides. Industry standards and best practices including those issued by the Government Accountability Office and the Office of Management and Budget stress that information systems (e.g., general support systems, major applications, and minor applications) must document and assess the potential impact that proposed system changes may have on the operational processes and security posture of the system. The IT industry best practices recognize this as an essential aspect of effective system management, as well as being part of the continuous monitoring and maintenance of security accreditation of federal systems.

  2. Configuration Management is a critical control for ensuring the integrity, security, and reliability of the IRS information systems. Absent a disciplined process for controlling configuration changes, management cannot be assured that its systems will operate as intended, or that systems’ maintenance will be performed in a cost-effective or timely manner.

Process Definition
  1. Process Description. The information set below describes the characteristics of Configuration Management.

    • Configuration Management is the process responsible for providing accurate and complete configuration information about related software and IT infrastructure components, including their attributes and relationships, to support other software engineering and service management processes.

    • Businesses require quality IT services to be provided in an economical manner. To be both efficient and effective, all organizations need to have control of their IT services and infrastructure.

    • Configuration Management provides a model of a service's IT infrastructure or the entire IT infrastructure by identifying, managing, maintaining and verifying the configuration items in existence, their attributes and their relationships with other configuration items and the services they enable and support.

  2. Process Goal. The goal of Configuration Management is to provide accurate information on the current state of the software and IT infrastructure, the attributes of IT service related components, and their relationships to enhance the effectiveness of other software development and service management processes. This is accomplished through the identification, control and verification of those items declared to be within scope of the process. The key to this process is the identification of the relationships that exist among configuration items.

  3. Process Objectives. Process objectives describe material outcomes that are produced or achieved by the process. The following is a list of objectives for this process:

    • Help provide accurate assessment of the risk and impact of a change to a configuration item

    • Improve the assessment of the impact of a configuration item failure by readily identifying the services that it supports

    • Provide accurate configuration information to other software development and service management processes

    • Provide a snapshot of a known state of the IT environment or baseline of configuration items

    • Create a standard method for introducing, updating and tracking components or aggregated configuration items in the IT environment

    • Provide a standard automated technology and location for storing information about the configuration item

    • Ensure that all changes to the software and IT infrastructure, configuration items or component configuration item, that need to be managed are reflected on the software libraries and repositories

  4. Disciplines. Configuration Management is performed within the context of the 5 common disciplines that are applicable in development, operations, and security environment, as illustrated in the figure below. Although Configuration Management has a shared goal and objective in identifying, managing, and controlling the configuration items across the environments, its purpose and application is slightly different but complimentary.

    1. Under the software development environment, Configuration Management ensures that the development and release processes are controllable and repeatable through identification, tracking, and protecting the project’s deliverable or software products from unauthorized change.

    2. Under the operational environment, Configuration Management ensures the integrity of configurations required to control the services and IT infrastructure by establishing and maintaining accurate and complete configuration item records in a CMDB.

    3. Under the security environment, Configuration Management ensures management and control of secure configurations for an information system to enable security and facilitate management of risk.

    The following figure illustrates the 5 Common Disciplines.

  5. Configuration Item. A configuration item (CI) is a component of a service or system that can be identified as a self-contained unit for purposes of change control and identification. A configuration item can be a primitive (single) component or an aggregate (collection) of other configuration items. The level at which a configuration item is considered primitive or aggregate is decided by the system in which it is created, maintained, and managed. The table below describes common types of configuration items based on CI Type and CI Subtype.

Roles and Responsibilities

  1. Each process defines at least one role. Each role is assigned to perform specific tasks within the process. The responsibilities of a role are confined to the specific process. They do not imply any functional standing within the hierarchy of an organization. For example, the process manager role does not imply the role is associated with or fulfilled by someone with functional management responsibilities within the organization. Within a specific process, there can be more than one individual associated with a specific role. Additionally, a single individual can assume more than one role within the process although typically not at the same time.

    Some of the roles may not be applicable for other IT projects.

Program Management and Review

  1. The IT CM PMO shall manage and evaluate the process based on the following guiding principles:

    1. Process Management. Configuration Management will have a single Process Owner and a separate Process Manager, responsible for implementing and ensuring adherence to the process. The process will be reviewed regularly to ensure that it continues to support the business requirements of the enterprise. Process metrics will be focused on providing relevant information as opposed to merely presenting raw data.

    2. People. Roles and responsibilities for the process must be clearly defined and appropriately staffed with people having the required skills and training. The mission, goals, scope and importance of the process must be clearly and regularly communicated by upper management to the staff and business customers of IT. All IT staff (direct and indirect users of the process) shall be trained at the appropriate level to enable them to support the process. It is imperative that people working in, supporting or interacting with the process in any manner understand what they are supposed to do. Without that understanding Configuration Management will not be successful.

    3. Process. Modifications to the process must be approved by the Process Owner. The design of the process must include appropriate interfaces with other processes to facilitate data sharing, escalation and workflow. The process must be capable of providing data to support real-time requirements as well as historical/trending data for overall process improvement initiatives. The process must be fully documented, published and accessible to the various stakeholders of the process. The process will be reviewed on a periodic basis to ensure it continues to support organizational goals and objectives (continuous improvement). The process must include Inputs, Outputs, Controls, Metrics, Activities, and Roles and Responsibilities along with documented process flows. The process will be kept straight forward, rational, and easy to understand. The process must meet operational and business requirements.

    4. Technology and Tools. All tools selected must conform to the enterprise architectural standards and direction. Existing in-house tools and technology will be used wherever possible, new tools will only be entertained if they satisfy a business need that cannot be met by current in-house tools. The selection of supporting tools must be process driven and based on the requirements of the business. Selected tools must provide ease of deployment, customization and use. Automated workflow, notification and escalation will be deployed wherever possible to minimize delays, ensure consistency, reduce manual intervention and ensure appropriate parties are made aware of issues requiring their attention. Technology and tools should be used to augment the process capabilities, not become an end themselves.

Program Controls

  1. Program controls are driven by the policies and guiding principles on how the process will operate.

  1. Controls provide direction on the operation of processes and define constraints or boundaries within which the process must operate.

    Name Description
    Baselines Documented agreed descriptions of the attributes and/or specifications of a configuration item, at a point in time, which serves as the basis for defining change.
    Change Management Policies APolicies and mandates for change control of configuration items.
    Configuration Audits An examination of a configuration item to determine whether it confirms to its design and requirements including the integrity of its record.
    Configuration Reports The frequency and distribution for regularly produced Configuration Management reports on the status of configuration items.
    Model A defined structure and approach to recording relationships between configuration items that includes the level of detail that the organization wants to trace the relationships.
    Plan A documented plan that will define the scope, objective, resources, change authority, and activities for Configuration Management.
    Taxonomy Defined standards for naming and classifying configuration items including terms and definitions.
  1. Metrics are used for the quantitative and periodic assessment of a process. They should be associated with targets that are set based on specific business objectives. Metrics provide information related to the goals and objectives of a process and are used to take corrective action when desired results are not being achieved and can be used to drive continual improvement of process effectiveness and efficiency.

  2. Management will regularly set targets for process performance, gather quantifiable data related to different functions of Configuration Management, and review that data to make informed decisions and take appropriate corrective action, if necessary. All measurements must have a defined data dictionary, map to the organizational strategic goals, and be documented in the Configuration Management Process Measurement Plan.

  3. Enterprise and local Configuration Management processes, including Configuration Management tool owners, must produce metrics and measurement reports to measure the effectiveness and efficiency of the Configuration Management process.

Tailoring Guidelines
  1. The tailoring guidelines identify the allowable variations of the IT organization’s standard process as needed for adjustments (adding, deleting, modifying) relative to specific operational or functional needs of another organization. Process tailoring is about roles and procedures, not the standard process or major activities defined in this process. All tailoring request, with supporting rationale, must be submitted in writing to and approved by the CM Process Owner.

  1. An activity is a major unit of work to be completed in achieving the objectives of the process. A process consists of a sequence of related activities that transforms inputs into outputs and performed by the roles defined in the process. Activities are measurable in terms of efficiency and effectiveness. Configuration Management consist of the following 5 processes:

    1. Management & Planning. This activity establishes the CM Plan that describes the appropriate Configuration Management process that will be performed during the product or project lifecycle. It details the Configuration Management activities, the assigned roles and responsibilities, change authority, tools, and appropriate process to manage the configuration items within scope of the CM Plan.

    2. Configuration Identification. This activity identifies the configuration items that will be controlled, establishes standard naming convention and schemes, version control, structural relationships between configuration items, assignment of ownership, identification and selection of key attributes, and establishes configuration baselines.

    3. Configuration Control. This activity is responsible for managing changes and release implementation of changes to configuration items and baseline configuration documentation by leveraging on existing formal change and release processes. It also ensures that only authorized and identifiable configuration items are in the infrastructure and that there is a corresponding accurate and complete configuration item record representing its actual or physical configuration item.

    4. Configuration Status Accounting. This activity establishes the process for recording, managing, and reporting on the status of approved configuration documentation and information, including traceability of all changes.

    5. Configuration Verification & Audit. This activity establishes the integrity in the configuration documentation and information used as the basis for configuration control and support of the product throughout the software development lifecycle by maintaining the integrity of the configuration baselines. It confirms that the resulting configuration baselines and documentation conform to the standards or requirements, and also confirms the integrity of a system or product prior to delivery.

In accordance with IRM 2.150.1 Configuration Management Policy, IT organizations must follow the Configuration Management process and implement it for their programs, projects, and systems throughout the lifecycle. Configuration Management includes identifying and baselining configuration items, controlling and recording changes, reporting on the status and implementation of the changes, and conducting review and evaluation to ensure that the build conforms to the requirements and all items identified as part of the configuration are present in the product baseline. The following sections describes further details for each of the Configuration Management process.

Management & Planning
  1. IT organizations, programs, and projects must develop a plan and strategy to define the scope, objectives, resources, and appropriate Configuration Management process in a Project/Product CM Plan. This also applies to any organizations providing IT services to the IRS, such as IRS Business and Functional Units and Managed Service Providers. Once the Project/Product CM Plan is approved through the OneSDLC Readiness Exit Review, it is valid for 3-years and can be used for subsequent releases including at the OneSDLC Product Exit Review.

  2. IT organizations may establish an organizational or Associate Chief Information Office (ACIO)-level CM Plan that defines their current resources, including CCBs, and Configuration Management process to manage their existing configuration items. IT Projects that are owned by their ACIO may leverage on their ACIO-CM Plan for their product configuration items and used for their OneSDLC Readiness Exit Review by using the Addendum to the ACIO CM Plan (Addendum) to document the agreement and any deviations against their ACIO CM Plan. If there are too many deviations against the ACIO CM Plan, it is recommended that the project develops a Project/Product CM Plan. The ACIO CM Plan is valid for 3-years and must be revised or re-certified by the IT CM Process Owner every 3-years to maintain currency and used by their IT Projects to leverage from. Exclusions to using the ACIO CM Plan are:

    • Non-IT organizations. IRS Business Units and Functional Units must develop a Project/Product CM Plan.

    • Managed Service Providers. Systems owned and managed by the vendor must develop a Project/Product CM Plan or functional equivalent. Functional equivalent must be reviewed and approved by IT CM PMO for OneSDLC Exit Reviews.

  3. Planning for Configuration Management is essential to the success of managing and delivering the product or IT solution into deployment through sustaining operations since Configuration Management extends throughout the system’s life cycle. Planning involves the “what” and “how” activities are to be performed and performing these activities according to the CM Plan. The most significant activity is identifying the appropriate Configuration Management process to manage the configuration items. In configuration planning, the following items must be considered into the CM Plan:

    1. Scope and Objective. The project/product scope and objective must be clearly defined.

    2. Roles and Responsibilities. The appropriate Configuration Management roles and description of its responsibilities, including other related process roles must be defined and assigned.

    3. Configuration Management Tools. Configuration Management and related tools must be identified that will be used to support Configuration Management and related activities.

    4. Configuration Management Training. Personnel assigned to support Configuration Management must be trained in the process and/or tools.

    5. Contractor/Vendor Control. IT projects that acquire or make use of commercial tools and/or services, must define type of service provided to IRS, where the service is hosted, interfaces with IRS systems, and level of customization.

    6. Software Development Life Cycle (SDLC) Model. The type of SDLC approach (e.g., Agile, COTS, Managed Service, or Waterfall) that will be used must be defined to establish the appropriate Configuration Management process to develop or change the configuration item.

  4. A standard CM Plan Data Item Description (DID), including the Addendum DID has been established by the IT CM PMO. Organizations, programs, and projects may differ in scope and complexity and a single format may not always be applicable. The standard CM Plan DID provides the minimum format for plans and maximum amount for flexibility. If the section for the format is not applicable, the sentence “Not Applicable” for this section must be inserted to indicate that this section has not been overlooked.


    ACIO CM Plan updates and recertifications must be submitted to the IT CM PMO for review and approval by the IT CM Process Owner.


    In reference to Secure Configuration Management, IRM CM-09 Configuration Management Plan is what establishes the requirement to document, define configuration item, and develop a CM Plan.

Configuration Identification
  1. IT organizations, programs, and projects must identify candidate software configuration items that will be placed under configuration control and management. This involves understanding the software configuration within the context of system configuration and selecting software configuration items. Software configuration is the functional and physical characteristics of the hardware and software defined in the technical documentation or achieved in the product. The following are examples of software items that are candidate software configuration items:

    • plans

    • specifications and design documents

    • testing materials

    • software tools

    • source and executable codes

    • code libraries

    • data and data dictionaries

    • documentation for installation, maintenance, operations and software use

  2. Identify configuration items. Configuration Identification is responsible for the planning and preparation for identifying configuration items. This includes modeling the IT infrastructure to determine what configuration items will look like and how they are related to each other. It also includes the development of a taxonomy, standard naming conventions, configuration item selection and classification, and assignment of CI Ownership for defining configuration item attributes. The following items below describe the steps for identifying configuration items.

    1. Build Logical Model. IT infrastructure components must have a representation in the models and standard methods for modeling configuration items and their relationships must be defined and applied consistently across the IT organization. Standard methods for modeling services, applications, and components must be established and then creating conceptual logical model of the IT infrastructure. These standard methods and conceptual models will become requirements for modeling the services, application, and IT infrastructure in the system architecture and CMDB. The logical model defines the scope of the Configuration Management activities, that is the level of detail that the organization would want to trace the relationships. Initially beginning with a high-level approach by defining several key services and tracing them back to the application to servers and other service components.

    2. Establish Taxonomy and Standard Naming Convention. Services and applications can be referred to by multiple names. Standardization of terms for service and application components is required to consistently model the service and all of its related components. Standard terms and definitions must be defined and published. This includes establishing a standard naming convention with required data elements as part of the control. Accordingly, using the logical model, define what parts of an application will be designated as a service, what parts will be designated as an application, and what are the parts that are running on the platform.

    3. Configuration Identification Index (CII). Establish a standard CII methodology to assign a unique identifier for each configuration item so that it can be distinguished from all other configuration items and their associated product configuration information. See IRM Configuration Identification Index (CII) Guidelines including IRM Document Versioning Guidelines for configuration documentation. For IT infrastructure configuration items using automated tools such as a CMDB, a unique identifier assignment is usually part of its automated functionality to automatically assigned configuration items.

    4. Define CI Types and CI Subtypes. Establishing configuration item classification based on CI Type and CI Subtypes enables management and organization of configuration items. Define CI Types based on the logical model for IT infrastructure components. This entails categorizing any and all configuration items that will be managed (e.g., services, applications, servers, database). This will also establish guidelines for the selection of configuration items and define a set of CI Types and its CI Subtypes. The selection of configuration items and the level to which they are defined are very important parameters in the design of the CMDB. That is, if the level is defined too granular, the CMDB can become cumbersome, bloated and difficult to manage. If the level is too high, the CMDB may not meet the operational requirements of the supported processes. An example of a CI Type and CI Subtype is listed in Figure 2.150.2-1. For configuration documentation, see IRM Configuration Documentation Classification Guide.

    5. Assign CI Owner. Identify and assign an owner for each CI Type including CI Subtypes. The CI Owner will be responsible for identifying the information about the CI Type, such as what attributes are needed and valid values and/or parameters for each attribute, and the source for gathering the information. CI Ownership may be the business owner and/or technical owner, specifically the group or individual that will be responsible for approving or making the change. CI Ownership may be assigned at the organization, group, or individual level. For organization or group, such as using an organizational symbol or assignment group, it is recommended to also identify an individual point of contact.

    6. Define Configuration Item Attributes. The CI Owner defines and selects the attributes for each CI Type that they own. An attribute is a piece of information about the configuration item such as name, location, version number, etc. This includes any valid values and/or parameters for each attribute. Configuration item attributes are used to identify the characteristics of the configuration item and also used for controls and baselines. Attributes may be discoverable or non-discoverable. Discoverable attributes are configuration item attributes gathered through auto discovery tools in hardware assets and added in the CMDB. Non-discoverable attributes are configuration item attributes that are manually defined, updated, and collected from sources used and added in the CMDB.

    7. Identify Sources of Information for Configuration Items. Identify the sources where the information can be found for each configuration item, such as application, software products, and hardware repositories. Auto discovery tools can also be used to identify and gather the information and related components on the network. For configuration documentation, the source may be in a specific repository such as SharePoint or Documentum.

    8. Establish Relationships or Interfaces. Relationships or interfaces between the service (Business Service and Application Service) and IT infrastructure configuration items must be determined to identify impact of a change or incident against other configuration items. Relationships, and the ability to map those relationships to configuration items, are the defining characteristic of Configuration Management.

      Documenting relationships may be done by any of the following:

      • a short description between configuration items

      • table

      • block diagram

      • engineering drawing

      For an automated CMDB, mapping of relationships between configuration item components may be done manually or automatically. Relationships are what convert an inventory of the IT infrastructure in the CMDB that can be used for creating service maps, determining impact, analyzing the risk of a change, and building a model of the IT infrastructure.


      The IT CM PMO provides a CI Structure (CIS) Chart as a resource to manually document configuration item relationships.

    9. Register Configuration Items or Populate the CMDB. Identify and select configuration items that will be managed and controlled. Configuration item records are what is managed by Configuration Management in order to manage its actual or physical configuration item. Configuration item records may be registered manually or through an automated tool, such as a CMDB. For a CMDB, begin populating the CMDB with CI Types and associated attributes. Use incremental approach to build out one CI Type at a time and verify with the CI Owner before proceeding to the next. For example, identify the application associated with each server and then identify all the attributes and owners associated with each one, initiate mapping and populate the CMDB with the CI Type and configuration details, and verify the relationship mapping between the application, hardware, and other components is correct with the CI Owner.


      The IT CM PMO provides a CM Worksheet template as a resource to manually register configuration items. It is the organization, program, and project’ responsibility to maintain their configuration items and system inventory to manage, control, and report on their documentation, hardware, and software configuration items.

  3. Baseline Configuration Items. Software baseline is a formally approved version of software configuration items that is formally agreed upon and establishes the basis for a formal change process for future changes. Baselines must be established as the software configuration item progresses through the software development lifecycle. There are 3 types of software or system baselines:

    1. Functional baseline defines the functional requirements of the system or system specifications (system level architecture and design) and its interface characteristics containing the system’s capability, functionality, and overall performance. It is established upon completion of system requirements review under the Domain Architecture Phase. This consist of approved configuration documentation describing a system or top level configuration item’s performance, such as the Vision, Scope and Architecture.

    2. Allocated baseline defines the configuration items that compose the system and how it is distributed or allocated across lower-level configuration items. It is established upon completion of software requirements and software interface requirements review under the Logical and Physical Design Phase. This consist of approved configuration documentation describing the functional and interface characteristics allocated from the system for each configuration item, such as Interface Control Document and Simplified Design Specification Report.

    3. Product baseline defines the release contents or configuration items of the project for production. It is established upon completion of all technical documentation and software for product testing and acceptance that culminates in the Configuration Audits under the Systems Development Phase. This consist of the source code and approved technical documentation describing the configuration of a configuration item for production and operational support, such as Computer Operator Handbook.

    For software that is acquired, its origin and initial integrity must be established. Following the acquisition of a software, changes to the item must be formally approved and baseline according to the appropriate procedure.


    In reference to Secure Configuration Management, IRM CM-02 Baseline Configuration requirements for baseline configurations for systems and system components include connectivity, operational, and communications aspects of systems. Baseline configurations are documented, formally reviewed, and agreed-upon specifications for systems or configuration items within those systems. Baseline configurations serve as a basis for future builds, releases, or changes to systems and include security and privacy control implementations, operational procedures, information about system components, network topology, and logical placement of components in the system architecture. Maintaining baseline configurations requires creating new baselines as organizational systems change over time. Baseline configurations of systems reflect the current enterprise architecture.

  4. Establish Software Libraries. A software library is a controlled collection of software and related documentation for software development. It is also used for software release management and deployment activities. Software libraries must be established for source code management and control, development, and testing. Tools used to support the software libraries must support Configuration Management controls such as version and access control. Software libraries must also be established for configuration item related documentation to maintain current baselines and previous versions. These should include plans, designs, requirements, and any technical and operational documentation that support the software.

Configuration Control
  1. IT organizations, programs, and projects must implement a controlled change process and provide tailored methods and standard operating procedures for effectively planning, recording, controlling, and validating product requirements and data that contain the requirements. Tailoring will depend on the organization and the level of control or complexity needed. The change process is the cornerstone activity for Configuration Management including tracking changes to ensure that the configuration of the product is accurately known at any given time. This is accomplished by identifying each baseline and tracking all subsequent changes made to that baseline. Accordingly, Configuration Control is about managing and controlling the configuration item baseline. All changes must be associated with the configuration item, documented, and submitted through a change request. The authority for making decisions on proposed changes is under the CCB. For smaller projects, the authority is delegated to a lower-level change authority, SCCB, based on specific criteria defined for its scope and control. Formal change procedures are defined in IRM 2.22.1 Unified Work Request (UWR) Process for business application and IRM 2.125.2 Change Management Process for infrastructure.

  2. Approved change requests are implemented using defined software procedures based on type of SDLC. Additionally, since there are a number of approved change requests that might be implemented simultaneously, it is critical to track which change request are incorporated for each software versions and baselines. Formal system development procedures are defined in IRM 2.5 Systems Development.


    In reference to Secure Configuration Management, IRM SA-10 Developer Configuration Management sets the requirements for developers of systems, system components, system service etc., to document, manage, and control integrity change for configuration item under Configuration Management.

  3. Approved change requests are also received by software quality assurance to plan, prepare, and implement test activities, such as developing test plans, test cases and test scripts and documenting and reporting on the test results to Software Developers for correcting software defects. Individual software applications are integrated with other software products for the final system integration testing. Successful completion of integration testing prepares the software for software release management. Formal testing procedures are defined in IRM 2.127.2 IT Testing Process and Procedures.

  4. Configuration records are updated throughout the software development process and prepared for Configuration Status Accounting & Reporting.

  5. Software release management is the identification, packaging, and delivery of all software configuration items, such as executable program, documentation (e.g., Version Description Documentation), release notes, and configuration data. This includes delivery of the installation instructions and other data concerning the use of the new system, and defining the environment on which the software will run.

  6. As part of the change process closure, completed changes may undergo configuration audits and/or software quality assurance to ensure that only approved changes have been made.

  7. Final updates to configuration records are made and a new baseline is established once the system is deployed into production.


    In reference to Secure Configuration Management, IRM CM-03 Configuration Change Control requirements includes changes to baseline configurations, configuration items of systems, operational procedures, configuration settings for system components, remediate vulnerabilities, and unscheduled or unauthorized changes. For changes that impact privacy risk, the senior agency official for privacy updates privacy impact assessments and system of records notices. For new systems or major upgrades, organizations consider including representatives from the development organizations on the Configuration Control Boards or Change Advisory Boards. Monitoring of changes includes activities before and after changes are made to systems and the auditing activities required to implement such changes.

  8. Changes to configuration item records in the CMDB must be associated with a change request and submitted by the CI Owner to change the baseline and maintain data compliance. For incorrect configuration item records, an incident must be reported to correct the record and restore the configuration item baseline.

Configuration Status Accounting
  1. IT organizations, programs, and projects must identify, record, and maintain software configuration status information for software configuration items that were approved and baseline and report its activities for management, software engineering, and other related needs. This includes establishing measurements and tracking change request status, deviations, and waivers as it progresses through the software development process. For example:

    • Record and report on all approved configuration documentation including changes

    • Record and report the status of all change requests associated with each configuration item

    • Record and report on the history of change approvals

    • Record and report the status on the verification and validation activities

  2. Identify the type of report(s) (formal or informal), frequency of reporting, and the audience to report on the configuration status information. For example:

    • What kind of report to produce for each software configuration item

    • What data to report and source of the data

    • What is the frequency for reporting on the status for each software configuration item

    • Who are the stakeholders that will receive the reports

Configuration Verification & Audit
  1. IT organizations, programs, and projects, at discretion, may perform Configuration Audits to ensure that Configuration Management processes are followed, configuration items are built based on requirements, and the integrity of the configuration baselines are maintained. Specifically, Configuration Audits ensure that (1) baselines are complete, correct and consistent in relation to functional and physical specifications; (2) approved changes were correctly implemented and verified; (3) no authorized changes have occurred; and (4) software products are ready for release. Therefore Configuration Audit increases software visibility and establishes traceability of changes throughout the development lifecycle and reveals whether the product requirements are being satisfied and whether the preceding baseline has been fulfilled. The audits enable project management to evaluate the integrity of the software product being developed, resolve issues that may have been raised by the audit, and correct defects in the development process. Configuration Audits are conducted prior to software deployment to ensure that the software product has been built and tested according to specified requirements and all items that are designated as part of the configuration are installed as defined by its requirements.

  2. There are two formal types of Configuration Audits that are performed prior to release of the software product to production: Functional Configuration Audit (FCA) and Physical Configuration Audit (PCA). FCA ensures that each item of the software product has been tested to determine that it satisfies the functions defined in the specifications. PCA determines whether all items identified as being part of the configuration are present in the product baseline. The FCA/PCA are formal audit processes in software development lifecycle methodologies, such as COTS and Waterfall. FCA/PCA Audits are normally performed by Software Quality Assurance. Further details of the FCA/PCA are described below:

    1. Functional Configuration Audit. FCA is conducted once the software product has been developed and tested. The audit intends to confirm that the software product is verified and tested relative to its allocated requirements in relation to its high-level requirements. FCA ensures that the functional and performance attributes of a configuration item (baseline components) are achieved (done right thing). The FCA should occur at least once for new development but may be held more frequently as determined by the Project/Product Manager.

    2. Physical Configuration Audit. PCA is conducted once the software product has been fully completed and all corrective actions have been closed. PCA ensures that each configuration item, as-built, conforms to the technical documentation that defines it, that is: (1) all items identified as being part of the configuration are present in the product baseline; (2) the correct version and revision of each part are included in the product baseline; and (3) each item corresponds to information contain in the baseline’s configuration status report. In other words, the configuration item (baseline components) is installed as defined by the requirements in its detailed design documentation (done thing right). PCA should be accomplished on the product baseline for each release to verify its authenticity before the full deployment decision to verify compliance with the stated requirements and to ensure that all life-cycle documentation supports the added functionality.


    FCA/PCA activities are defined through a checklist. Since each product have different scope and complexity, there is no standard template for the FCA/PCA checklist. However, standard requirements described above, specifically identification of configuration baseline items and status of changes to configuration baseline items, should define FCA/PCA requirements to define the checklist.

  3. Configuration Audits for Agile may be performed at the end of each sprint. Unlike the traditional method (FCA/PCA), the approach is flexible, iterative, and focuses on continuous communication and collaboration between the audit team and stakeholders, and completed in short time frames. An audit backlog is created that defines the scope of the items for the audit which are reviewed and prioritized based on risk and value, and updated based on the needs of the organization, such as emerging issues experienced by stakeholders. The audit team collaborates with the stakeholders on how an item in the backlog will be tested and examined, including the expected value from the test and audit requirements. The audit is conducted and completed within sprint intervals by dividing the audit into small increments and grouping user stories into sprints. At Sprint Review Meetings, the backlog items are reviewed and the completed work is demonstrated to the Product Owner to determine whether the items satisfy the requirements.. A Point of View report is developed that summarizes all relevant insights gained from the observations and stories.

  4. Configuration Verification & Audit for the CMDB must be performed to ensure data quality and integrity. Configuration Verification activities are performed by CI Owners and supported by the CI Librarian/Analyst that is responsible for managing configuration item records in the CMDB. The following Configuration Verification activities are:

    1. Data Integrity Verification. Review for (1) unregistered components and (2) missing components (previously registered components).

    2. Data Quality Verification. Review for (1) completeness (i.e., required fields and recommended fields are complete); (2) correctness (i.e., duplicate configuration items, orphan configuration item relationships, and staleness/old configuration item(s); and (3) compliance (i.e., desired state based on standard configuration for each configuration item.

    A verification report is generated to document the overall status and for any discrepancies and corrective actions required to reconcile the discrepancies. Changes to configuration item and its record must be submitted through Change Management to manage and control the baseline. Corrections to configuration item and its record must be submitted through Incident Management to restore the baseline.

    Configuration Audit on the CMDB must also be performed by a Configuration Auditor that supports the CM Process Manager. The objective is to evaluate whether the Configuration Verification process is being performed including measuring the accuracy and quality of data in the CMDB. Configuration Audits may also trigger corrective actions required to reconcile the discrepancies and distributed to CI Owners for resolved.

Configuration Identification Index (CII) and Document Versioning Guidelines

  1. The following sections below provides the guidance for assigning Configuration Identification Index and Document Versioning for documentation configuration items.

CII Guidelines

  1. The CII guidance applies to manually recording and registering configuration items, usually for configuration documentation. The CII is composed of 5 fields: Config-, ID-, Index-, Ver-, and Date. The fields are separated by a hyphen and when joined, make up the CII. For example, the figure below illustrates how the CII is decomposed for IT:EO:DMPG-PLN-IT_CM_Plan-V1.0-01012022.

    1. The “Configuration (Config)” field is defined as the CI Owner and will contain the IRS organizational symbols or external Service Provider as input. A CI Owner is the one that owns and is responsible for the specific configuration item and the primary validation point for information related to that configuration item. The CI Owner responsibilities include maintaining ownership of the configuration item, reports changes in ownership, and reports changes in the configuration item information. The field size is limited to 15-characters. If the organizational symbol exceeds 15-characters, it will need to be truncated starting from the left to meet the 15-character limit. For example, for OS:IT:EO:DMPG:GRMB would be truncated to IT:EO:DMPG- or EO:DMPG:GRMB.

    2. The “Identification (ID)” field is defined as the CI Classification. The CI Classification contains the CI Type and specific class of a configuration item (or CI Subtypes). For configuration documentation, the various CI Subtypes may be requirements, designs, or plans. This field is limited to 4-characters in length. For example, IT:EO-DMPG-PLN-. For the CI Classification, see IRM Configuration Document Classification Guide for reference.

    3. The “Index” field is defined as the configuration item reference containing the abbreviated title of the configuration item. This field is limited to 15-characters in length. For example, IT:EO:DMPG-PLN-IT_CM_Plan-.

    4. The “Version (Ver)” field is defined as the version of the configuration item. For configuration documentation, IRM Document Versioning Guidelines, provides the instructions for versioning guidelines. In addition, when finalizing the document version, all draft versions listed in the “Change History” or “Record of Changes” table will need to be removed and its nature of changes summarized under the final version. The version must start with a “V” in the CII, such as V1.0, V2.0, etc. This field is limited to 4-characters in length. For example, IT:EO:DMPG-PLN-IT_CM_Plan-V1.0-.

    5. The “Date” field is defined as the date of creation or update of the configuration item. For documentation configuration items, IRM Document Versioning Guidelines, also provides the instructions for dates as part of versioning guidelines. The date must be 8-characters long, such as, “01012022” or “12312022”. For example, IT:EO:DMPG-PLN-IT_CM_Plan-V1.0-01012022.

  2. For documentation configuration items, the CII should be inserted as a footer in the document. Any changes to the document, the Ver- and Date- fields will need to be updated on the CII.


    The CII may also be used as a Document Identification Number.

Document Versioning Guidelines

  1. Document versioning refers to the use and management of multiple versions of a document. The fundamental aspect of document versioning is tracking changes and tracking the creation of multiple document versions such as by numbering document versions in successions. Below are the document version control guidelines, and as illustrated in the figure below.

    Figure 2.150.2-4

    This is an Image: 60767012.gif

    Please click here for the text description of the image.

    1. Document Date. Date the document is created or revised, and is incorporated as part of the CII footer in the document and appears on every succeeding page.

    2. Version Number. Current version number is created, and is incorporated as part of the CII footer in the document and appears on every succeeding page.

    3. First Draft. Registering the first and subsequent drafts of the document.

      The following steps are listed below:

      1. The first draft of a document will be Version 0.1.

      2. Subsequent drafts will increase by “0.1” in the version number ( e.g., 0.2, 0.3, 0.4, …0.9, 0.10, 0.11).

      3. Date will change with each draft version.

      4. All changes will be documented in the change history table.

    4. Final Version. Registering the first final version of the document.

      The following steps are listed below:

      1. Document will be deemed as final after all reviewers have provided final comments and dispositioned.

      2. The first final version of a document will be Version 1.0.

      3. Change to the latest date when the document becomes final.

      4. Remove draft versions(s) and only final version remain with “Initial release” language in the change history table.

    5. Revisions to a Final Version. Registering updates to the first final version of the document.

      The following steps are listed below:

      1. Final documents undergoing revisions will be Version X.1 for the first draft of the previous final revision.

      2. While the document is under review, subsequent draft versions will increase by “0.1” (e.g., Version 1.1, Version 1.2, Version 1.3).

      3. Date will change with each draft version.

      4. All changes will be documented in the change history table.

    6. Subsequent Finals. Registering updates to subsequent final versions of the document.

      The following steps are listed below:

      1. When the revised document is deemed final, the version will increase by “1.0” over the version being revised (e.g., draft Version 1.3 will become final Version 2.0).

      2. Change to the latest date when the document becomes final.

      3. Remove draft version(s) and only final version remain with summary of changes from previous draft(s) in the change history table.

      4. Subsequent final documents will have an increase of “1.0” in the final version number (2.0, 3.0, 4.0, etc.).


        Revisions to subsequent final versions within the same published year may retain the Version X.1 if the changes to the solution are minor. However, after the published year, subsequent versions must be rounded to the next final version.


    For Revisions to a Final Version, if the changes are minor (editorial) and released within the same year, it is acceptable to use the next final version as Version 1.1, Version 1.2, etc. for multiple releases. However, if the changes are substantial and requires stakeholder review, then Step 5 or Step 6 must be followed.
