Code Review Checklist Template Xls

Standard Operating Procedure: Code Review Checklist Template (XLS)

1. Document Control & Revision History

2. Executive Summary & Scope

This document defines the mandatory protocol for the deployment, utilization, and auditing of the code_review_checklist.xls template. The objective is to standardize technical debt reduction, enforce security compliance (OWASP/CWE), and ensure architectural alignment across all enterprise software delivery lifecycles (SDLC). This SOP applies to all engineering squads, DevOps teams, and external contractors. It satisfies audit requirements for SOC2 Type II and ISO/IEC 27001 documentation standards.

3. Prerequisites & Tool Requirements

• Software Access: Authorized Read/Write access to the centralized Engineering_Governance SharePoint/Git repository.
• Office Suite: Microsoft Excel 2019+ or authorized enterprise-grade O365 instance.
• Version Control: Active branch access on Git (GitHub Enterprise/GitLab).
• Certifications: Reviewers must hold current "Senior-Level Code Contributor" internal certification.
• Permissions: Integrated IDE plugin access for automated linting and static analysis (SAST) hooks.

4. Roles & Responsibilities (RACI Matrix)

5. Step-by-Step Operational Procedure

Phase I: Preparation & Template Initialization

• Initialize code_review_checklist.xls from the master template stored in the repository root.
• Tag the Excel file with the specific Jira Ticket ID or Git Merge Request (MR) reference.
• Verify that the target branch is synchronized with main to avoid merge conflicts.

Phase II: Execution of Technical Review

• Functional Correctness: Confirm the code achieves the desired outcome defined in the ticket requirements.
• Security Compliance: Run internal SAST tools; verify no hardcoded secrets, API keys, or PII are present.
• Performance Benchmarks: Evaluate time complexity (Big O) and database query efficiency.
• Maintainability: Ensure code follows established style guides (DRY, SOLID principles).

Phase III: Documentation & Approval

• Fill all status cells in the XLS template (Pass/Fail/NA).
• Append specific line-item comments for every "Fail" or "Needs Improvement" status.
• Attach the final XLS to the Git Merge Request documentation header.
• Finalize the electronic sign-off by the Lead Reviewer.

6. Quality Assurance & Verification Criteria

• Tolerance Threshold: Zero tolerance for "Critical" or "High" severity vulnerabilities identified by SAST tools.
• Acceptance Benchmark: 100% completion of the "Mandatory" section of the checklist; minimum 80% coverage for "Best Practice" items.
• Audit Frequency: Random selection of 10% of closed MRs to be audited by the Quality Assurance team monthly.
• Artifact Retention: The finalized .xls file must be stored in the project's /docs/audit/ directory for a minimum of 3 years.

7. Practical Troubleshooting Scenarios

Scenario A: Discrepancy between Checklist and Automated Test Results

• Failure: The Excel checklist indicates "Pass," but CI/CD pipeline tests return a "Fail."
• Corrective Action: The CI/CD pipeline is the single source of truth. Immediately revert the Checklist status to "Fail." Halt the deployment. Re-run local unit tests to replicate the CI failure. Do not proceed until the local environment mimics the CI environment.

Scenario B: Template Corruption/Locked File

• Failure: The XLS file returns "Access Denied" or "File Corrupt" when attempting to update status.
• Corrective Action: Do not attempt manual repairs. Delete the local copy. Perform a git pull on the template repository to restore the clean master version. Contact the DevOps team if the repository copy itself is corrupted.

Scenario C: Reviewer-Developer Disagreement on Best Practices

• Failure: Deadlock on subjective code style issues during the review process.
• Corrective Action: Escalate to the Technical Architect. The Architect's decision is final and must be recorded in the "Audit Notes" section of the XLS to prevent recurring debates.
