Estimation

1. Syed Zeeshan Nasir Project Software Estimation IS/17133/Aut-07 BS 4thB

2. Software Project Estimation Outline: Estimation overview Estimation resources Estimation decomposition Estimation Technique Estimation methods Slim Cocomo

3. 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

4. Why its important to you! Software project implemented Software costing Quality software product Time Duration Solution of future problem

5. Estimation Resources Human resources Reusable SW Resources Environmental Resources

6. Decomposition technique Software Sizing Problem Based Estimation

7. 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

8. Cost Estimation Models SLIM (Software Life Cycle Management) Calibration Build Advantages of SLIM Drawbacks of SLIM

9. 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

10. 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
