Schedule Metrics


SM Score = Estimated No. of Days in Iteration / Actual No. of Days spent in Iteration

Score(%) Action
SM < 50 Immediately inform Supervisor Ben Gan about the slip within 24 hours. Then use the same mitigation as the category 50 < SM < 90 and seriously consider dropping tasks.
50 < SM <= 90 Re-estimate the tasks for the future iterations. Consume buffer days. Analyze cause of delay and make necessary corrections.
90 < SM <= 110 Estimates are fairy accurate, and we are roughly on track. Consider add/deduct number of days behind schedule from buffer days.
110 < SM <= 150 Gross over-estimated the effort required. Re-estimate the tasks for future iterations and add number of days to buffer days.
150 < SM Immediately inform Supervisor Ben Gan about the slip within 24 hours. Then use the same mitigation as the category 110 < SM <= 150


Bug Metrics


Impact Score

Severity Description
Low Impact (1 ~ 4 points) Inconsequential. Simple typo error or minor user interface misalignment.
High Impact (5 ~ 9 points) Non-critical functionalities are not working, but still system runs.
Critical Impact (10 points) The system or core functionality is down.


Mitigation Plan

Total Score = # Bugs (Low) x 1 + # Bugs (High) x 5 + # Bugs (Critical) x 10

Bug Score Action
Score <= 10 Fix during buffer time.
10 < Score <= 20 Fix during planned debugging time in current iteration.
Score > 20 Halt current development and fix the bug(s) immediately. Reschedules if necessary.
