Chapter 3 – Methodology
Life Cycle models followed :
This project consisted of developing a Web-based application that was used as a
CRM tool. Since an application was designed, coded, and implemented it was fitting to
use the Software Development Life Cycle (SDLC) and a somewhat modified ancillary
model, the Prototyping Life Cycle which was discussed earlier in this paper and depicted
in Figure 4. According to Fioravanti (2005), there are two Prototyping Life Cycles that
one can use in application development. The first is called the throw-away prototype and
is usually used in a rapid application development (RAD) project/environment and the
second is the real life cycle in which follows more methodical development (Fioravanti,
2005). While this project needed to be developed rather rapidly the throw-away
prototype just did not seem to be as suitable for the project as the true Prototyping Life
Cycle. The phases of this life cycle allowed for rapid development, but also, for the
flexibility of going back to previous phases and building on itself; similar to the Spiral
Life Cycle.
1. Requirements: The application was built from the requirements given to this
author by the owner of the project at ARC. The requirements gathering phase
consisted of meeting with management personnel at ARC to gain a thorough
understanding of the goals they wanted to accomplish with the application. These
requirements were then used throughout the project and were revisited during
development of the individual project modules. Once all of the requirements were
met the application was deemed complete.
