Reuse CategoriesCategory Sub-Category Definition
I) New Products that are completely new
i) Design for Reuse
Products that require an additional upfront investment to improve the potential reusability
II) Modified Products that are inherited, but are tailored
ii) Deleted Products that are removed from the system
III) Adopted Products that are incorporated unmodified (a.k.a. “black box” reuse)
iii) Managed Products that are incorporated unmodified and with minimal testing

COSYSMO 2.0 Implementation Results• Across 44 projects at 1
diversified organization• Using COSYSMO:
– PRED(.30) = 14%– PRED(.40) = 20%– PRED(.50) = 20%– R2 = 0.50
• Using COSYSMO 2.0:– PRED(.30) = 34%– PRED(.40) = 50%– PRED(.50) = 57%– R2 = 0.72
• Result: 36 of 44 (82%) estimates improved
