Quality Goals

Code Coverage

• Achieve 90% code coverage for unit tests and 80% code coverage for end-to-end tests.

• Automated tests cover 75% of the codebase, ensuring that the majority of the code is exercised during testing activities.

Code Review

• Code reviews consistently identify adherence to coding standards, with 95% of reviewed code meeting established guidelines for formatting, naming conventions, and language-specific best practices.

Code Maintainability

• Cyclomatic Complexity: A software module has a cyclomatic complexity of 15, indicating moderate complexity that may require refactoring for improved maintainability.

• Code Duplication: The codebase contains 20% duplicated code, indicating opportunities to refactor and consolidate duplicate logic.

• Code Readability: Code review feedback indicates that the majority of the code follows established coding standards and is easy to understand.

Security Standards

• Conduct quarterly security assessments with no high-severity vulnerabilities remaining unresolved.

• Adherence to OWASP standards, to address common threats and vulnerabilities.

Test Environment Stability

• Ensure that the test environment has at least 99% uptime and minimal unplanned downtime.

Root Cause Analysis Effectiveness

• Ensure that at-least 80% of identified root causes lead to process improvements and preventive actions.

Test Coverage

• Complete at-least 90% of planned test cases within the specified test cycle time.

• Ensure that 75% of executed test cases identify at least one defect.

• Automated regression tests cover 50-70% of the critical functionalities, ensuring that most critical features are tested for regressions after each release.

Test Case Maintenance Efficiency

• Reduce the average time required to update test cases due to requirement changes by 30%.

Bug Fixing Rate

• Reduce the average time to fix bugs by 15% compared to the previous quarter.

• The average time taken to resolve reported defects is 2 days, indicating a MTTR(Mean time to resolution) of 2 days across all reported issues.

Escaped Defects

• These are the defects reported by the customer within the first week of a new software release, highlighting the presence of escaped defects that were not identified during testing.

• Limit test-escaped defects (defects reported by the customer) to less than 2% of all reported defects.

Defect Density

• Maintain a defect density of fewer than 3 critical defects and 5 minor defects per 1,000 lines of code.

Defect Closure Rate

• Maintain a defect closure rate of 90% or higher, indicating that defects are resolved promptly.

Defect Rejection Rate

• Keep the defect rejection rate below 10%, indicating that most reported defects are valid.

Performance Metrics

• Maintain a login time of under 1 second for 95% of users.

• The system maintains a response time of less than 2 seconds for 95% of requests.

• CPU utilization is well under 50% even for the maximum load.

• No 50X errors to be noticed for the non-functional test environment in use.

Security Metrics

• Resolve high-impact vulnerabilities within 5 days and low-impact vulnerabilities within 30 days of identification.

Change Management Metrics

For all the production deployments, Regular reporting on change management metrics, such as change success rate, time to approve changes, and incidents related to changes, helps track performance and identify areas for improvement.
