Study Notes
Why Manage Changes?
- Software change is necessary and inevitable due to evolving business needs, market opportunities, and regulations.
- Managing changes helps prevent expectation gaps and associated problems, frustration, rework, and wasted time.
Change Control Policy
- A change control policy should be communicated to handle proposed changes in requirements.
- The policy should cover the process for submitting change requests, evaluating changes, and implementing approved changes.
Change Control Process
- The change control process helps project leaders make informed business decisions while controlling the product's life-cycle cost and project schedule.
- The process involves:
- Evaluating change requests to understand consequences and impact
- Making change decisions with consideration of technical feasibility, cost, and business requirements
- Implementing approved changes and updating affected work products
- Verifying changes through peer review
- The process ensures that suggested changes are not lost or overlooked and that stakeholders are informed of change requests and status.
Measuring Change Activity
- Measuring change activity helps assess the stability of requirements.
- Tracking aspects include:
- Total number of change requests received, open, and closed
- Cumulative number of added, deleted, and modified requirements
- Number of requests originating from each change origin
- Total effort devoted to processing and implementing change requests
Tracing Requirements
- Tracing requirements involves tracking the life of a requirement from origin to implementation.
- Trace links allow for forward and backward tracing of requirements.
- Requirements tracing helps:
- Find missing requirements
- Identify unnecessary requirements
- Perform change impact analysis
- Maintain software systems
- Reuse product components
- Track project implementation status
- A requirements traceability matrix can be used to represent trace information between system elements.
Applying Requirements Tracing
- Educate the team about tracing concepts and importance
- Select link relationships to define and choose a traceability matrix type
- Identify parts of the product for tracing and assign tracing responsibilities
- Modify development procedures to update links after implementing requirements or approved changes
- Define labeling conventions for unique identifiers
- Audit trace information periodically to ensure accuracy
