None of. ANSWER: b) TestingComment: Except for testing , all other activities does not require actual execution of software. ANSWER: a) ProductComment: Validation is determining if product meets specification. ANSWER: a) True Comment: Main objective of development testing is to find as many as failures so defects can be identified and fixed while objective of acceptance testing is to confirm software works as expected. In this chapter, the modeling life cycle will briefly be presented. The life-cycle model of consumption suggests that consumption is based on average lifetime income instead of income at any given age. This process is used to model or provide a framework for technical and non-technical activities to deliver a quality system which meets or exceeds a business"s expectations or manage decision-making progression. Such rational selection of life cycle options is the central issue at the early stagy of life cycle design . a) Waterfall & RAD In this model testing is done side by side of the development. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. Which of the following life cycle model can be chosen if the development team has less experience on similar projects? What is a life cycle model?
