TAILIEUCHUNG - COCOMO ESTIMATION

Cocomo estimation COCOMO (COnstructive COst MOdel) Boehm: group of models In the late 1970s, 63 projects (7) effort = c(size)k Effort was measured in pm (person month) Size was measured in kdsi, thousands of delivered source code instructions C, k | Presentation Topic COCOMO ESTIMATION Cocomo estimation COCOMO (COnstructive COst MOdel) Boehm: group of models In the late 1970s, 63 projects (7) effort = c(size)k Effort was measured in pm (person month) Size was measured in kdsi, thousands of delivered source code instructions C, k COCOMO COCOMO (COnstructive COst MOdel) Developed by Boehm in 1981 Became one of the most popular and most transparent cost model Mathematical model based on the data from 63 historical software project COCOMO II Published in 1995 To address issue on non-sequential and rapid development process models, reengineering, reuse driven approaches, object oriented approach etc Has three sub-models – application composition, early design and post-architecture COCOMO 81 COCOMO stands for COnstructive COst MOdel It is an open system First published by Dr Barry Bohem in 1981 Worked quite well for projects in the 80’s and early 90’s COCOMO 81 COCOMO has three different models (each one increasing
