Introduction
Agile Modeling is a practice based software process whose scope is to cover both architectural
and software process point of view. An agile philosophy for software engineering stresses four
key issues: the importance of self-organizing teams that have control over the work they perform:
communication and collaboration between team members and between practitioners and their
customers, a recognition that change represents an opportunity; and an emphasis on rapid
delivery of software that satisfies the customer. Agile process models have been designed to
address each of these issues.
5.1 An Agile View of Process
In the software industry, a large number of projects fail and billions of dollars are spent on failed
software projects. Lack of an end user involvement, poor requirements, and unrealistic schedules
are some of the top reasons of such failure. Agile software development is an approach that
addresses these problems through a real communication between programmers and customers.
Thus, there is a need to quantify software agility. In this topic, an approach for quantifying
software agility is provided by modeling the key concepts in agile software and proposing a
