An agile process reduces the agility and cost of change because software is released in increments and change can be better controlled within an increment. Agility argue that a well designed agile process “flattens” the cost of change curve shown in following figure, allowing a software team to accommodate changes late in a software project

The best software process is personal and team process model one that is close to the people who will be doing the work. Watts Humphrey proposed two process models. Models “Personal Software Process (PSP)” and “Team Software Process (TSP).” Both require hard work, training, and coordination, but both are achievable. Personal Software Process (PSP) The

Unified process (UP) is an architecture centric, use case driven, iterative and incremental development process. UP is also referred to as the unified software development process. The Unified Process is an attempt to draw on the best features and characteristics of traditional software process models, but characterize them in a way that implements many of
