Baseline establishment
Purpose & Scope
Baselines are the fundamental basis of configuration management. Baselines provide:
- A common point of reference to stakeholders needed for their activities.
- An assurance of the stability and consistency of information.
- A common communication of product definition.
- An instrument for transfer of authority over all or a portion of a product’s definition.
Before any document or data set is considered part of a baseline, it must be reviewed to ensure that the document is complete, valid and suitable for use. A release system/process is employed to validate the document and file integrity.
A process or method to establish baselines must take into account:
- What baselines are to be established in time (defining baselines against project and system lifecycles) as well as in relation to the system architecture (defining baselines against sub-systems, particular system views etc).
- When and how baselines will be defined.
- The process for assuring integrity of the baseline.
- The authority to formalise baselines and approve baseline changes.
- If and when change authority will transfer and the process by which proposed changes will be dispositioned to affect a particular baseline.
- How to document the formal establishment decision.
- Activities to review or quality assure the baseline before establishment.
Learning objectives
- Understanding the concept of baselines and what it implies in general practical working scenarios.
- Knowledge about how baselines can be identified in relation to project and system lifecycles and to system architectures.
- Knowledge about what differs a formal baseline from an informal baseline.
Managed capability
- Process and/or method for establishing baselines provide support for all concerned stakeholders.
- Baselines are established with satisfying results.
Performed capability
- Process and/or method descriptions exist for establishing baselines, but they are incomplete or too abstract to provide any real support.
- Baselines are established in a structured manner to some degree.
Incomplete capability
- No documented process or method exists for establishing baselines.
- Baselines are not at all established or are established in an arbitrary manner.
