A mapping from advantageous software engineering principles to desired software qualities is sketched in Table 6.4 . Give specific explanations why “ Modularity ” is mapping to “ Reliability, ” “ Correctness, ” “ Performance, ” “ Interoperability, ” “ Maintainability, ” and “ Portability. ” Or, do you disagree on some of those suggested mappings?
