  • Example: "These instructions apply to all phases of software development, including change request submission, approval, implementation, and version control using ClearQuest and ClearCase."

2.0 Roles and Responsibilities

• Software Developer: Responsible for implementing changes, checking code into ClearCase, and updating the status of change requests in ClearQuest.
• Configuration Management (CM) Lead: Manages the ClearCase repository, ensures proper version control, and audits software baselines.
• Software Change Control Board (SCCB): Reviews and approves or rejects software change requests (SCRs). Oversees the software change control process.
• Software Quality Assurance (SQA): Ensures compliance with quality standards during the software change control process.
• Project Manager: Oversees the overall process and ensures changes are aligned with project goals and schedules.

3.0 Software Change Control Process Using IBM ClearQuest

3.1 Software Change Request (SCR) Submission

• Initiating a Change Request: A team member identifies a need for a software change (e.g., bug fix, feature request, or improvement) and submits a Software Change Request (SCR) using ClearQuest.

  • SCR Form: The following fields must be filled in during SCR submission:
    • Change Request ID (automatically assigned).
    • Title: Brief description of the requested change.
    • Description: Detailed explanation of the issue or enhancement, including steps to reproduce (if applicable).
    • Priority: Assign a priority (e.g., P1 = Critical, P2 = High, P3 = Medium).
    • Severity: Define the potential impact (e.g., Major, Minor).
    • Requester: Name of the individual submitting the request.
    • Attachments: Include any relevant supporting documents (e.g., logs, screenshots).

• Triage and Assignment: The SCR is reviewed by the CM Lead or Project Manager to validate completeness and then assigned to the appropriate developer or team for further investigation and implementation.

3.2 SCCB Review and Approval

• SCCB Role: The SCCB reviews SCRs during regular meetings. The SCCB evaluates each request based on its impact on the project, safety, performance, and schedule.

  • Review Criteria: SCRs are evaluated on:
    • Impact on system functionality and safety.
    • Complexity of implementation.
    • Required resources (time, budget, personnel).
    • Compatibility with existing software versions.

• Approval or Rejection: Based on the review, the SCCB will:

  • Approve the SCR for implementation.
  • Reject the SCR with reasons.
  • Request additional information or modification of the SCR.

• Status Update in ClearQuest: Once the decision is made, the SCR status is updated in ClearQuest (e.g., "Approved," "Rejected," "In Progress").

3.3 Implementing Approved Changes

• Developer Assignment: Once the SCR is approved, the assigned developer begins implementing the change. All code modifications are made in compliance with coding standards and guidelines.
  • Example: "The developer must work in a designated ClearCase branch for the current version of the software. No changes should be made to the baseline until the change is fully implemented and tested."

3.4 Code Check-In to IBM ClearCase

• Check-In Procedures: After the changes are made, the developer checks the updated code into ClearCase.

  • Version Control: ClearCase manages software versions, ensuring all changes are tagged and versioned properly.
    • Branching Strategy: Use a branching strategy where each SCR is associated with a specific branch in ClearCase. This ensures changes are isolated and can be tested independently.
    • Version Tagging: Each software version is tagged with a unique version identifier that corresponds to the SCR in ClearQuest (e.g., v1.0.3-SCR#123).

• Developer Testing: Before submitting the change for final testing, the developer performs unit tests and verifies that the issue is resolved or the new feature works as intended.

3.5 Testing and Validation

• Integration Testing: Once the change is checked into ClearCase, the test team performs integration testing to ensure the change integrates properly with other software components and does not introduce new defects.
  • Example: “All changes must pass integration tests before being merged into the main branch.”
• SQA Verification: The SQA team audits the change to ensure compliance with quality and safety standards. SQA may also conduct independent testing to validate the change.

3.6 SCR Closure

• Closing the Change Request: After successful testing and validation, the SCR status in ClearQuest is updated to "Closed" by the developer or project lead.
  • Example: "Once testing is complete and no further issues are identified, the SCR status in ClearQuest will be updated to 'Closed,' indicating that the change has been fully implemented and verified."
• Audit Logs: The CM Lead ensures that all changes are properly logged in ClearCase, and a summary of the change is recorded in ClearQuest for traceability.

4.0 Software Configuration Management Using IBM ClearCase

4.1 Version Control and Branching Strategy

• Repository Setup: ClearCase will maintain all versions of the software in a controlled environment. Each change request (SCR) is associated with a specific branch to ensure isolation and traceability.

  • Mainline Branch: The mainline branch contains the official, stable version of the software.
  • Feature/Change Branches: Developers create a new branch for each SCR or feature being developed. Once changes are complete and tested, the branch is merged back into the mainline.

• Check-Out/Check-In Process:

  • Check-Out: Developers check out the required files from the ClearCase repository to modify them on a local workspace.
  • Check-In: Once the changes are complete, the developer checks the updated files back into ClearCase, following the project's version control and check-in policies.

4.2 Baseline Management

• Creating Baselines: A baseline is created in ClearCase for each major release or significant update. Baselines capture a snapshot of the software at a given point in time, ensuring traceability for each release.

  • Example: "A baseline will be established after the closure of all SCRs for a given release. The baseline will serve as the official version of the software for testing and deployment."

• Baseline Reviews: Before a baseline is officially approved, the SCCB conducts a review to ensure that all approved changes have been correctly implemented, tested, and documented.

4.3 Configuration Audits

• Configuration Audits: The CM Lead or SQA team conducts regular configuration audits to ensure that all software versions are properly maintained and that no unauthorized changes have been introduced into the system.
  • Example: "Configuration audits will be conducted at the end of each development phase to verify the integrity of all software baselines and ensure that all changes are traceable to approved SCRs."

5.0 Software Change Control Board (SCCB) Procedures

5.1 SCCB Meetings

• Meeting Schedule: The SCCB meets regularly (e.g., weekly or bi-weekly) to review pending SCRs, assess their impact, and prioritize the implementation of approved changes.
  • Example: "SCCB meetings will be held every Monday to review all submitted SCRs. Emergency meetings may be called for critical defects or high-priority changes."

5.2 SCCB Responsibilities

• Review and Approval: The SCCB is responsible for reviewing all SCRs for technical feasibility, safety implications, resource requirements, and schedule impacts.

  • Approval Workflow: Approved SCRs are assigned a priority and entered into the project backlog for implementation. The SCCB tracks each SCR's progress through to closure.

• Post-Implementation Review: After changes have been implemented, the SCCB reviews the outcome to ensure that the changes met the desired objectives without introducing new risks or issues.

6.0 Tools and Integration

• IBM ClearQuest: Manages the lifecycle of software change requests, providing an interface for submitting, tracking, and closing SCRs.
• IBM ClearCase: Manages version control and software configuration, ensuring traceability and proper versioning of code and documentation.
• Integration: ClearQuest and ClearCase are integrated to link SCRs to specific code changes, ensuring that all changes are traceable and auditable.

7.0 Metrics and Reporting
