SOFTWARE DEVELOPMENT METHODOLOGY

Methodology, with respect to software, refers to the procedures by which complex software solutions are created. Methodology is all encompassing – it defines how to build an application from the ground up, from defining the problem all the way through post-implementation support.

Although several proprietary methodologies abound for developing various types of software, they all follow a general pattern: Analysis, Design, and Implementation.

ANALYSIS:

The first stage in creating an application is to define the problem you wish to solve. To begin, the developer must take into account several preliminary questions: How effective is our current system? What does it lack? If we were to create a software solution to this problem, what functions must it carry out? These fundamental questions boil down to the three major aspects of the Analysis phase – Defining the context of the problem, identifying the problem, and defining the answer.

Inexperienced programmers, who would rather simply begin to write code, often consider this initial stage unnecessary. This couldn’t be further from the truth. ; The Analysis stage is the most crucial of all – because problems later on in development almost always occur from an oversight in the general planning of the way the software should be created.

DESIGN:

Once the problem and solution have been identified, the next step is to determine whether a softw...
