Fowler recommends using an agile process when your project involves:
Inception, elaboration, construction, and transition are the four RUP phases. During the inception phase, analysts define the scope, determine the feasibility of the project, understand user requirements, and prepare a software development plan. During the elaboration phase, analysts detail user requirements and develop a baseline architecture. During the construction phase, the software is coded, tested, and documented. During the transition phase, the system is deployed and the users are trained and supported. INCEPTION ELABORATION CONSTUCTION TRANSITION IECT IECT IECT

The Agile Methodologies are a response to the problems associated with the traditional SDLC methodology. The three key principles are a focus on adaptive rather than predictive methodologies, a focus on people rather than roles, and a focus on a self-adaptive process.
