Survey of "Driven Development" Methodologies

Software Development Methodology

According to 1 :

"A software development methodology is a framework used to structure, plan, and control the process of developing a software 

system.[1]"

Table 1 ^[8]

A software might range from a simple small application to a large and complex system in which the applications typically manage immense data sets and support complicated and extensive algorithms. Ad hoc approaches might sometimes work in developing small applications, because of the brilliance of the individuals developing it, but fails in most cases. Table 1 shows the effects of an improper development methodology. A software development process has requirements. The things that an organization must understand are what software system will be developed, how much time would the development take, and what would be the quality of the final product. The amount and the way the software system meets the requirements determines the quality of a software system, Hence, a software development methodology is a critical tool for reaching these, complex and difficult to manage, requirements [2].

Below are a list of few software development approaches. Till date we have development approaches like responsibility driven (RDD), test driven (TDD), behavior driven (BDD), domain driven(DDD), and model driven (MDD). All these approaches emphasize a core set of values and principles around which efficient software development practices, techniques, and tools have emerged. A developer should thoughtful choose among practices without losing their essence. But not all practices are congruent [3].
