Introduction

WaterFall According to en.wikipedia.org Waterfall "is a software development model first proposed in 1970 by w.w. Royce, in which development is seen as flowing steadily through the phase of requirements analysis, design, implementation, testing, (validation), integration, and maintenance". Waterfall method is the first published model of a software development process (1970). The basic principle is that the different processes (Analysis, Design, Coding, and Testing) are done sequentially. Output from one process is input to the next. Waterfall method advantages like simple, easy to understand and work with. Waterfall creates very detailed intermediate documentation after each process. In general it is difficult to find situations where the Waterfall method is especially suitable. For the method to work the requirements have to be basically written in stone. ...read more.

A disadvantage of the iterative process is that it implies that evaluation of the product occurs only after coding. This is an expensive proposition. A variation of the iterative process more appropriate to a HCI is the rapid prototyping. The Spiral Development process encompasses other process models. The iteration of the sub-problem with the highest associated risk must be identified and solved. To solve the problem any type of "normal" development process (Waterfall, Incremental, Prototyping, etc.) might be employed. Which one is suitable all depends on the risks identified. Its disadvantage is that is almost impossible to make initial time and cost estimates. Agile Process disadvantage is that is a Manifesto, so business people and developers must work together daily throughout the project. ...read more.

Conclusion

* Feature Driven Development (FDD) * Crystal Clear * Dynamic Software Development Method (DSDM) * Rapid Application Development (RAD) from James Martin (the very first Agile method) * Scrum * Xtreme Programming (XP) * Rational Unify Process (RUP), available at CERN Benefits of Agile Methods The benefits of an agile development with the advantages of a simple implementation, scrum significantly increases productivity and reduces time to benefits while facilitating adaptive, empirical systems development. Agile Development Method for my Organization IT Agile represents a number of lightweight methodologies including DSDM, Extreme Programming (XP) and Scrum. They follow principles from established management science focusing on the value creation, effective delivery of valuable software, offer delegation and empowerment and encourage a hands-off management style. For my organization I will introduce Scrum which is one the lightweight and a good management tool. Reference Jones, Capers. 1994.
