1981
The original COCOMO is introduced in Dr. Barry Boehm's textbook Software Engineering Economics. This model is now generally called "COCOMO 81".
1986
Costar 1.0 is released.
1987
Ada COCOMO and Incremental COCOMO are introduced (proceedings, Third COCOMO Users Group Meeting, Software Engineering Institute).
1988, 1989
Refinements are made to Ada COCOMO.
Costar 2.0 is released.
1990
Costar 3.0 is released.
1993
Costar 4.0 is released.
1995, 1996
Early papers describing COCOMO 2 published.
1997
The first calibration of COCOMO II is released by Dr. Boehm, and named "COCOMO II.1997".
Costar 5.0 is released, supporting COCOMO II.
1998
The second calibration of COCOMO II is released. It's named "COCOMO II.1998".
1999
COCOMO II.1998 is renamed to COCOMO II.1999 and then to COCOMO II.2000 (all three models are identical).
2000
The book Software Cost Estimation with COCOMO II (Dr. Barry Boehm, et al) is published to document how to apply the latest estimation model. Most of the original Software Engineering Economics is still applicable to modern software projects.
Costar 6.0 is released, and supports COCOMO II.2000, MBASE, REVIC, and schedule constraints.
