Decrease logistics burden and life cycle costs.
The effectiveness of a design for maintainability strategy can be measured using
maintenance metrics and industry benchmarks. Fuzzy logic can be used to measure
system design maintainability. The membership function for measuring the software
quality with respect to maintainability is presented in Chapter 1.
