Reuse Categories CategorySub-CategoryDefinition I) NewProducts that are completely new i) Design for Reuse Products that require an additional upfront investment to improve the potential reusability II) ModifiedProducts that are inherited, but are tailored ii) DeletedProducts that are removed from the system III) AdoptedProducts that are incorporated unmodified (a.k.a. “black box” reuse) iii) ManagedProducts that are incorporated unmodified and with minimal testing 7

COSYSMO 2.0 Implementation Results Across 44 projects at 1 diversified organization Using COSYSMO: –PRED(.30) = 14% –PRED(.40) = 20% –PRED(.50) = 20% –R 2 = 0.50 Using COSYSMO 2.0: –PRED(.30) = 34% –PRED(.40) = 50% –PRED(.50) = 57% –R 2 = 0.72 Result: 36 of 44 (82%) estimates improved September 10, 20099
