Context/Background

The system is a financial software application with multiple modules. A software development team needs to analyze and assess the impact of a proposed change to a specific module. The system’s analysability is crucial for efficient change management and maintenance. Tools and practices are in place to support code documentation, dependency mapping, and change simulation.

A software development team initiates an impact analysis for a proposed change to a specific module of the financial software application.

Metric/Acceptance Criteria

The system’s analysability requirement will be considered met when the following precise metrics are achieved:

• Change Impact Assessment Time:
  • The team must be able to assess the impact of the proposed change within 2 hours
  • This time starts from the moment the team begins reviewing relevant documentation and source code
  • The assessment should cover all potential areas affected by the change
• Code Comment Density:
  • The affected module must have a minimum code comment density of 20%
  • This density should be measured using automated code analysis tools
  • Comments should be meaningful and provide clear explanations of code functionality
• Dependency Mapping:
  • The system must provide a visual dependency map of the module, that indicates all dependencies on and from other components
  • Generation time for the dependency map must not exceed 5 minutes
  • The map should be accurate, showing 100% of actual dependencies
• Overall Compliance:
  • All three criteria (assessment time, comment density, and dependency mapping) must be met for the requirement to be satisfied
  • Compliance should be verified through at least 3 different change scenarios
  • Any failures in meeting these criteria should be documented and addressed
  • The system should maintain this level of analysability for at least 90% of all modules
