9 Chapter 11 Project Dashboard Regular measurements Quantitative Qualitative Transparency Pitfalls of assessment or misunderstandings of why you measure. 1. Too much time spent at a cost to real work 2. Gaming the perceived intent of the measuring 3. Measuring people and not the project You get what you measure! 9

10 Measure more than one thing Recommendations: Go back to your drivers, constraints, and floats Pick at least four Those four are the areas you are most likely to modify during the project. Measure them! You need to see what to change You need more than just the start and end dates. 10

11 Measuring progress towards completion What is meant by completion? the only accurate way to measure progress for a software project is to measure how many features the project team has completed. What about serial projects? 11

18 How to know what s happening? Pick a few measurements: Schedule estimates vs. actuals When people are assigned vs. when they are needed Requirements changes (after baseline is set) Fault feedback ratio (ratio of fixes that don t fix to total fixes) Cost to fix defects Defect find, close and open rates Indicators of problems but you still need to figure out why! 18

19 Time lost is never going to be regained With no schedule you would not know what time was lost! With no schedule when you are over budget and delivery is not near you can only imagine you lost time somewhere! With a schedule but no tangible evidence of progress, no one notices the time that is lost. 19

23 Rate of Change Figure 11.9 (Page 217) Requirements Change Chart Major Reqts changed Minor Reqts changed Simple Criterion: Interface changes between modules tend to create defects Minor change effects one module Major change effects more than one module 23

24 Number of of Changes Requirements Change Chart (Fig. 11.9) Minor Major Week 24

25 Fault Feedback Ratio Number of Fixes that do not fix the problem Total Number of Fixes FFR 10% You are having serious problems fixing problems! NOTE. The earlier you measure FFR, the more feedback you can get 25

26 Defects Closed Fault Feedback Ratio & Closed Defects CSc 171/233 Fall % FFR Defects Closed 50% 40% 30% 20% 10% Fault Feedback Ratio % Week Fig

28 Some good rules The longer it takes to fix a problem the more likely that parts of the system are not understood! The longer it takes to find the problem, the less is known about the product or the less is known about how to test the product comprehensively! In either case, confidence in the product is low! 28

The risks and progress toward meeting release criteria Fig Initial Risk List Severity Risk Description Likelihood if it occurs Exposure Trigger Date Lucinda & her staff won't be 1 available for prtotype reviews High High High, High 1-May when we need them Mitigation Plan 1. Explain schedule to Lucinda 2. Keep her apprised of progress 3. Warn her 1 week in advance 2 Suipply chain thing will change entire DB design itf it occurs before Sept 1 High Medium Medium, High 1-Sep Continue to talk to Lucinda about the disruption these changes could make. Give her a date for when we can take changes. 32

35 Weekly Weather reports: A quick assessment! Project Schedule is on target Minor Schedule concern, but schedule can be met Schedule concern, can be met with extra effort Current Schedule or Feature Set is highly risky Schedule or Feature Set cannot be met under current conditions Cannot meet Schedule or the desired Feature Set 35
