Explanation : S1 is total number of modules defined in the program architecture. S2 is total number of modules whose correct function depends on the source of data input or that produces data to be used elsewhere. S3 is the number of modules whose correct function depends on prior processing. Program structure (D1) is defined as if architectural design was developed using a distinct method then D1 is 1 otherwise it is zero. Module independence: D2 = 1 - (S2 / S1) Module not dependent on prior processing: D3 = 1 - (S3 /S1) So, option (B) is correct.
The Evolutionary Model model is preferred for software development when the requirements are not clear.
In a Waterfall model, each phase must be completed before the next phase can begin
Rapid Application Development uses minimal in favor of rapid prototype(functionally equivalent component of product)
Rational Unified Processdivides the development process into four distinct phases: business modeling, analysis and design, implementation, testing, and deployment.
