1. Evaluation of Software Design Presented by: Praneeth Ganapavarapu (CSC-532 fall-04)

2. Project Hardware Software(75%) 90% problems found in testing phase

3. Software design metrics Product metrics Network metrics Stability metrics Process metrics

4. Evaluation of Quality Process based approach Tool based approach

5. Automation aid Selector [1]

6. Decision among alternatives Prototypes Proposing and answering a series of “what if”.

7. Model for design Evaluation Certainty case Uncertainty case

8. Certainty X – functionality of program ‘x’ Prog. ‘x’ is correct iff x B X, Y are specifications of B S i = scaling function X solves for Y iff S i (X i ) > S i (Y i )

9. Uncertainity Matrix PL. PL i,j PL = [i,j]

10. Conclusion More research should be undertaken in the measurement of software design, adopting different design methodologies using industrial software data In this study data complexity and control flow were used to measure of the quality of the program Further to be researched in measures of maintainability and reliability, which can be affected by the quality of design
