Syed Zeeshan Nasir Project Software Estimation IS/17133/Aut-07 BS 4thB
Software Project Estimation  Outline: Estimation overview Estimation resources  Estimation decomposition Estimation Technique Estimation methods Slim Cocomo
Estimation Estimation is the art of science Estimation is the feasibility report Estimation provide a road map for success software engineering All software product depend upon estimation
Why its important to you! Software project implemented   Software costing	 Quality software product Time Duration Solution of future problem
Estimation Resources Human resources Reusable SW Resources Environmental Resources
Decomposition technique Software  Sizing Problem Based Estimation
Estimation Method An estimation method to be used with experimental design An estimation method to be used with non-experimental design An estimation method to be used with both experimental and non-experimental design
Cost Estimation Models SLIM (Software Life Cycle Management) Calibration  Build Advantages of SLIM Drawbacks of SLIM
COCOMO'81 Boehm's COCOMO model is one of the mostly used models commercially Basic, intermediate, detailed Advantages of COCOMO'81 Drawbacks of COCOMO'81
started in late 90s  COCOMO'81 is not enough to apply to newer software development practices COCOMO II has three different models The Early Design Model The Post-Architecture Model  The Importance of Good Estimation COCOMO'II
