Sdlc Metrics: Our Guide
Diving into the world of software development requires an understanding of important parameters known as Software Development Life Cycle (SDLC) metrics. These metrics are indispensable tools that allow developers to efficiently measure and control the effectiveness and efficiency of the development processes. In this blog post, we will delve into the essential SDLC metrics, their role in enhancing software quality, and how they streamline the software development process.
Requirements Stability Index (RSI)
RSI tracks requirement changes during SDLC; low RSI suggests consistent requirements and clear project scope.
Defect Density gauges code quality by dividing identified defects by software size in a specific period, highlighting areas for improvement.
Defect Leakage Ratio (DLR)
DLR assesses testing team effectiveness by comparing post- release defects to total testing phase defects.
Schedule Variance (SV)
SV compares the actual project progress with the planned progress. It measures the deviation of project scheduling and helps assess the efficiency of the project management process.
Cost Variance (CV)
CV compares actual project cost to planned cost, indicating financial efficiency and budget adherence in SDLC..
Requirement Test Coverage (RTC)
RTC is the percentage of requirements that have been tested and verified. It ensures that all requirements have been adequately tested, reducing the risk of defects.
Code Coverage gauges testing thoroughness by assessing the percentage of executed source code, revealing areas needing more testing.
Test Execution Rate
Test Execution Rate quantifies testing team productivity by counting executed test cases in a specific time frame, evaluating efficiency.
Test Case Pass Rate
Test Case Pass Rate calculates the percentage of passed test cases in a cycle, assessing software quality and highlighting areas for improvement.
Change Request Response Time (CRRT)
CRRT assesses project team efficiency in managing scope changes impact on project timelines by measuring the time to evaluate, approve, or reject change requests in SDLC.
Customer Satisfaction Index (CSI)
CSI assesses customer satisfaction with software through surveys, feedback, and interviews, influencing future projects and the development team’s reputation.
