2. What Makes a Good Metric? What is it measuring? Why do we care? How easy is it to gather & compute? Could you do it well and still suck? Could you do it poorly and still be great? How do you cheat? How do you balance the cheating?

5. EQF from Lister/DeMarco An EQF of 5 is pretty good (i.e. averaging about 1/5 or 20 percent off.) The median for schedule estimating is about a 4, with the highest sustained scores at 8 to 9. Lister and DeMarco have never known anybody to sustain a 10 (just 10 percent off). Typical disaster project is 1.8

6. EQF Distribution Curve (LGC) EQF for duration has a theoretical minimum of 2.0

8. (EQF-2) Distribution Curve (LGC data)

9. LGC Estimation Quality LGC’s EQF measurement is pretty good. Our p(50) is 4.8, versus an industry average around 4 and a best sustained in the ~8-10. Our p(10) is 2.8, which is not bad. Calendar projects should have EQF = ~∞ EQF can be used with scope on Y-axis

11. Comments about DDE and DRE Can be for a release or a product Can be all defects or just P1/P0 Can be all defects or just customer defects

12. DDE and DRE SCOPUS Queries Ignore Closed, Duplicate, and Enhancements Per product is easy Per release requires release date info and is subject to version reporting
