Presentation Transcript

  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. Tool based approach • Automation aid • Selector [1]

  6. Selector[1] • 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 • Si = scaling function • X solves for Y iff Si(Xi) > Si (Yi)

  9. Uncertainity • Matrix PL. • PLi,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

  11. References • [1] Developing New Approaches for Software Design Quality Improvement Based on Subjective Evaluations Mika V. Mäntylä • [2] Test Software Evaluation Using Data Logging Winston Chou John L.Anderson Jr. • [3] A management tool for evaluation of software designs Sergio Cardenas-Garcia and Marvin V.Zelkowitz
