Decision among alternatives Prototypes Proposing and answering a series

of “what if”.

Model for design Evaluation

Certainty case Uncertainty case

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)

Uncertainity

PL = [i,j]

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
