Process and Procedure

  1. Process and Procedure


  1. This document describes the formal process for implementing the requirements of the Integrated Process Architecture (IPA) process. It provides an operational definition of the major components of the process and how to perform each step in the process. This document also describes the logical arrangements of steps that are essential to successfully completing the process and achieving its desirable outcome.

  1. All proposed changes to this document must be submitted in writing, with supporting rationale, to Demand Management and Program Governance, Enterprise Operations.


  1. A process is defined as “A set of related activities that accomplish a common goal”. The process definition laid out in this document further breaks down these Activities into Tasks, each of which have a complete set of attributes defined such as data and tool specifications and the role(s) responsible for executing the tasks. The document also includes process goal and objectives, metrics, role definitions, policies and other process related attributes

Process Description
  1. The Integrated Process Architecture (IPA) is the process for integrating Information Technology (IT) enterprise processes that will provide an enterprise view of an integrated process lifecycle for the organization’s set of standard processes.

  1. The process goal describes a specific purpose or achievement toward which the efforts of the process are directed. Each process has a specific focus and when combined with the other processes, forms a comprehensive framework for delivering and managing services.

  2. The goal of IPA is to provide an enterprise view of an integrated process lifecycle in order to enhance IT efficiency, customer service focus, and enable process improvements that will benefit project and service delivery.

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

    • Enhance IT efficiency and customer service focus

    • Provide an enterprise view of an integrated process lifecycle

    • Provide a clear and documented blueprint to IT business processes and context of their use

    • Identify cross-process gaps, overlaps, and discrepancies

    • Identify opportunities to improve and seamlessly integrate processes across the entire lifecycle


  1. A workflow consists of Activities and Tasks, Inputs and Outputs, Roles, and Flow Diagrams. It describes the tasks, procedural steps, organizations or people involved, required input and output information, and tools needed for each step of the process.

Main Process Flow Diagram
  1. Integrated Process Architecture Flow Diagram

  1. Process inputs are used as triggers to initiate the process and to produce the desired outputs. Users, stakeholders or other processes provide inputs. The following is a list of inputs for this process:

    Name Description Supplier
    Process Description Process Description documents from proposed process interfaces Process Manager
    Procedure Procedure documents from proposed process interfaces Process Manager
    Current IPA Baseline IPA IPM Process Manager
  1. Each process produces tangible outputs. These outputs can take the form of products or data and can be delivered to a user or stakeholder, or, they can be used as inputs to other processes. Outputs are measurable in terms of quantity and quality.

    Name Description Supplier
    Revised IPA Updated IPA IPM Process Manager
  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.

    ID Name Description
    IPA 1.0 Review the Process Review process for integration.
    IPA 2.0 Integrate the Process Review, analyze, and draft process integration.
    IPA 3.0 Finalize and Approve the IPA Finalize and publish process architecture.
  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.

Process Control

  1. Activities involved in ensuring a process is predictable, stable, and consistently operating at the target level of performance.

  1. Process controls represent the policies and guiding principles on how the process will operate. Controls provide direction over the operation of processes and define constraints or boundaries within which the process must operate.

    Name Description
    Policies All enterprise or core processes must comply with IPM requirements.
    Scope The scope of the IPA process is applicable to IT enterprise process owners.
  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 the IPA process, and review that data in order to make informed decisions and take appropriate corrective action, if necessary. All Measurements will have a defined data dictionary, map to the organizational strategic goals, and be documented in a Process Measurement Plan. The Process Measurement Plan template is available in the IT PAL.

  1. Policies outline a set of plans or courses of action that are intended to influence and determine decisions or actions of a process. Policies provide an element of governance over the process that provides alignment to business vision, mission and goals.

    Process Management

    Statement: The IPA process will have a single Process Owner and a separate Process Manager, responsible for implementation 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. The process will be designed and developed based on ROI to the business. Process metrics will be focused on providing relevant information as opposed to merely presenting raw data.


    Statement: 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.
    Rationale: 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 IPM will not be successful.


    Statement: Modifications to the IPM 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 in order to ensure it continues to support organizational goals and objectives (continuous improvement). The process must include Inputs, Outputs, Controls, Metrics, Activities, Tasks, Roles and Responsibilities, Tool and Data requirements along with documented process flows. The process will be kept straight forward, rational, and easy to understand.
    Rationale: The process must meet operational and business requirements.

    Technology and Tools

    Statement: 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. The selected tools must support heterogeneous platforms. 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.

    The tools used by this process are the following:
    • None

    Rationale: Technology and tools should be used to augment the process capabilities, not become an end themselves.

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 IPM owner.

  2. There is no tailoring for the IPA Process.


  1. Process training involves training all stakeholders about key processes that are crucial for an organization to deliver business objectives. Training provides clarity to employees on a set of procedures that needs to be carried out as part of the process and the best possible way to do them. List below the training resources available for this process:
