Metrics that helps us to know the project health status

Metrics help us in evaluating a project’s status, foresee risks, assess team productivity and quality of work we do. In this article I'd like to cover few metrics and their formulas which will help you to create some meaningful and beautiful metrics for your projects.

Delivery Metrics

It helps you to improve Delivery Effectiveness and On-Time Delivery Capability.

Scope Variance - It will act as an indicator to know if there is any scope creep in the project or not.

Scope Variance = (Actual Story points - Estimated Story points ) / (Estimated Story points )

Schedule Variance - It will act as an indicator to know whether a project schedule is ahead or behind.

SV = [(Actual End Date - Actual start Date)-(Planned End Date - Planned Start Date)] / (Planned End Date - Planned start Date)]

Quality Metrics

It helps you to improve Quality of the Product & Defect Prediction.

Defect Density - It gives an overall idea about spread of severity of defects and also about overall quality of coding.

DD = (No. of Story points Completed / (No. of Valid Defects)

Defect Escape Ratio - It gives an idea on how effectively test coverage was done by QA team.

DER = Customer Reported Defects (UAT & Production) / Total Valid Defects (QA + Customer Reported)

Test case Pass Rate - It indicates the quality of solution based on the percentage of passed test cases. It gives you a clear picture of the quality of the product being tested.

TPR = No. of Test cases Passed / No. of Test cases Executed

Test Coverage - It helps you to measure the amount of testing performed by a set of test.

TC = No. of test cases mapped to User Stories / Total no. of User Stories
