Introduction

Construction of a system, specially a software system, is quite an involved activity. From the
inception of an idea for a software system, until it is implemented and delivered to a customer,
and even after that, the system undergoes gradual development and evolution. The software is
said to have a life cycle composed of several phases. Each of these phases results in the development
of either a part of the system or something associated with the system, such as a test plan or a
user manual.
A number of process models have been proposed for developing software. In fact, each
organization that follows a process has its own customized version. Different processes can also
be divided into different activities and activities into sub-activities. However, in general, any
problem solving in software must consist of such activities as:
1. Requirement specification for understanding and clearly stating the problem
