The following is a table of all the metrics introduced in this book.
Table A-1. Codermetrics quick reference
Metric | Description | Formula |
---|---|---|
Points | Measure the overall productivity of each coder on assigned tasks | Points = Sum (Complexity for all completed tasks) |
Utility | Measure how many assigned tasks each coder completes | Utility = Number of tasks completed |
Power | Measure the average complexity of the tasks that a coder completes | Power = Points / Utility |
Assists | Measure the amount of coder interruptions and how much a coder helps others | Assists = Sum (Interrupts) + Sum (Helps) |
Temperature | Measure how “hot” or “cold” a coder is at any given time | Start with Temperature = 72; thereafter Temperature = Previous Temperature × (Current Points / Previous Points) |
O-Impact | Provide a single “Offensive Impact” number that summarizes the contributions of a coder in moving projects along | O-Impact = Points + Utility + Assists |
Saves | Measure how often a coder helps fix urgent production issues | Saves = Number of Product Issues with the highest Severity that a coder helps fix |
Tackles | Measure how many potential issues or opportunities a coder handles proactively | Tackles = Number of Pluses where coder demonstrates initiative or innovation |
Range | Measure how many areas of software a coder works on | Range = Number of Areas Worked by a coder |
D-Impact | Provide a single “Defensive Impact” number that summarizes the contributions of a coder in helping to avoid large problems | D-Impact = (Saves + Tackles) × Range ... |
