Q#1:

Organizations that are developing software solutions face the difficulty of choosing the right software development life cycle. An organization is planning to develop a small to medium sized project where requirements are clearly defined and fixed. Ample technical resources are also available with additional technical expertise. The company is not interested in an early prototype and the developers want to carry the Verification & Validation throughout the project life cycle (each phase).

As an IT manager, which of the following software development model you will suggest to your organization?

A) Water Fall Model
B) V- Model
C) Incremental Model

I. Justify your answer with any Five reasons.
II. How the testing and fixing (Quality Assurance and Software Reviews) will be carried out and what will be the effective cost of finding and fixing the faults, as the development progresses?

The waterfall model is a sequential design process, used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, production/implementation and maintenance.
The waterfall development model originates in the manufacturing and construction industries: highly structured physical environments in which after-the-fact changes are prohibitively costly, if not impossible. Since no formal software development methodologies existed at the time, this hardware-oriented model was simply adapted for software development.
