Introduction to PQM

Modularity is: Effort required to test program. The degree to which architectural, date or procedural design can be extended. The fuctional independence of program components. The amount of computing,resources and code required by a program to perform its function.

Maintainability is: Effort required to locate and fix an error in a program. Extent to which a program can be used in other applications. The amount of computing,resources and code required by a program to perform its function. The fuctional independence of program components.

Modularity is: Effort required to test program. The degree to which architectural, date or procedural design can be extended. The fuctional independence of program components. The amount of computing,resources and code required by a program to perform its function.

Effort required to test a program to ensure it performs its intended function is called: Extendibility. Modularity. Maintainability. Testability. Reusability. Performance. Usability.

Extent to which a program (or parts of a program) can be reused in other applications is called: Extendibility. Modularity. Maintainability. Testability. Reusability. Performance. Usability.
