Process and Procedure

  1. Component Capacity Management

Introduction

  1. This document describes the formal process for implementing the requirements of the Component Capacity Management 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 it desirable outcome.

Administration
  1. All proposed changes to this document should be submitted in writing, with supporting rationale, to the Solution Engineering.

Overview

  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 Component Capacity Management process translates business needs and plans into requirements for service and IT infrastructure, ensuring that the future business requirements for IT services are quantified, designed, planned and implemented in a timely fashion.

Goal
  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.

    • To manage, control and predict the performance, utilization and capacity of IT resources and individual IT Components

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

    • Provide a process for Monitoring, analyzing, tuning and upgrading component in the enterprise.

Workflow

  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.

Inputs
  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:

    Input Name Description Supplier
    Business Information Information about the business strategy, plans and requirements. Organization's Business Groups
    Service & Information Technology (IT) Component Relationships Information about the Services, the relationship to the business requirements, and infrastructure components needed. Business and IT Strategies, Service Strategy, IT plans and current budgets
    Component Performance and Capacity Information Capacity and Performance specifications from the manufacturer or developer; detailing expected performance and thresholds. Manufacturers and Suppliers
    Service Performance Issues Capacity related Incidents and Problems plus service level breaches. Incident and Problem Management processes
    Service Information Details of the Service Level Requirements, Service Level Agreements and data about the performance and utilization of the Services. SLM process
    Financial Information Information about the cost of providing a service. This will include, hardware, software, Component costs, and support and maintenance charges. Financial Management process
    Change Information (Request for Change) Capacity Management is responsible for assessing the impact of all proposed changes on the performance of infrastructure and services being provided. Change Management process
    Performance Information Current and historical performance and utilization information for IT services and IT infrastructure components. Capacity Management Information System (CMIS)
    Configuration Management System (CMIS) Information Configuration data on the components, services and relationships. Configuration Management System (CMIS)
    Workload / Operational Information Information about job schedules, operational tasks, and services dependencies. IT Operations team
    Patterns of Business Activity (PBA) An analysis of the workload showing how this varies according to demand. Demand Management
Outputs
  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. The following is a list of outputs for this process:

    Name Description Recipient
    Components Performance, Information and Reports Reports on the performance of Components using data in the CMIS.
    • Capacity Manager

    • Business Stakeholders

    • Operational Manager

    Workload Analysis and Reports Reports providing information about workloads that can be used for modeling, application sizing, and capacity planning.
    • Capacity Manager

    • Operational Manager

    • Business Stakeholders

    Ad Hoc Capacity and Performance Reports Performance and Utilization reports generated on an as needed basis, typically in response to capacity issues.
    • Capacity Manager

    • Operational Manager

    • Business Stakeholders

    Forecasts and Predictive Reports Reports used to plan capacity changes and proactively identify potential capacity issues.
    • Capacity Manager

    • Operational Manager

    • Business Stakeholders

Activities
  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. Identify the activities in the process and provide a brief description. The activities must correspond with the high-level process flow diagram above. The following is a list of activities for this process:

    ID Name Description
    CCap 1.0 Monitoring The purpose of this process step is to ensure the optimum use of the hardware and software components, that all agreed service levels can be achieved, and that business volumes are as expected
    CCap 2.0 Maintenance and Analysis The purpose of this process step is to determine the necessary changes to the configuration needed to implement the recommendations using the configuration management process, as needed
    CCap 3.0 Maintenance and Tuning The purpose of this process step is to determine the necessary changes to the configuration needed to implement the recommendations using the configuration management process, as needed.
    CCap 4.0 Component Ugrades The purpose of this process step is to introduce to the live operation services, any changes that have been identified by the monitoring and analysis activities. The implementation of any changes arising from these activities must be undertaken through a strict, formal Change Management process.
    CCap 5.0 Component Demand Management The purpose of this process step is to influence the demand for components and their use. A good Capacity forecast for components will anticipate and plan for peak demand. Demand Management is achieved by assigning resources according to priorities.
    CCap 6.0 Maintain the Capacity Management Information System The purpose of this process step is to ensure capacity management and performance information is easily available to stakeholders through a central repository or database. The database is used to collect much of the data input listed throughout this Component Capacity Management process description..
Roles
  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. The following roles have been identified for this process:

    Role Description Definition of Responsibility

Process Control

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

Controls
  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. The process controls are the following:

    Name Description
    Capacity Management Policy Business Capacity Management is a required activity mandated by the IRS CTO
    Scope Business Capacity Management process is limited to all ACIO areas with responsibility for Capacity Management
    Process Metric Business Capacity Process Monitors will continuously verify to what degree the Business Capacity Management Process is being used.
Metrics
  1. Management will regularly set targets for process performance, gather quantifiable data related to different functions of the Business Capacity Management 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.

Policies
  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 Business Capacity Management 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.
    People:
    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 Business Capacity Management will not be successful.
    Process:
    Statement: Modifications to the Business Capacity management 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, customizing 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
    • Capacity Management Information System

    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 Business Capacity Management Process owner.

Training

  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:

    Term Definition
    Business Capacity Management A strategic capacity management process done when decisions to expand or contract the infrastructure are made due to expected changes in demand by the business (addition of new applications, new infrastructure, etc.).
    RACI The RACI model is based on the principle that people act in one of four ways when executing a task. It accounts for the fact that more than one role may be active in performing a specific task while clearly defining specific responsibilities for that role. While many roles may be involved in a task only one is Accountable for the results. The actions are: R Responsible for the action (may do the task) A Accountable for the action (including approval) C Required to be Consulted on the action I Required to be Informed of the action If a task does not have an Accountable role indicated then the Responsible role is assumed to be accountable for the task.
    Service Level Agreement A service-level agreement is part of a service contract where the level of service is formally defined. In practice, the contracted delivery time (of the service) or performance.
    Service level management A set of practices for IT service management (ITSM) that focus on aligning it services with the needs of the business
    Service Level Requirements A statement from a customer to a service provider describing their service expectations. It includes the requirements of the customer from the service provider
