The project leader typically facilitates the work of the development team, eliminates bottlenecks, and helps the team stay focused in order to deliver software iterations on a regular basis. • Agile software development is a set of software development methods in which requirements and solutions evolve through collaborationbetween self-organizing,[1] cross-functional teams. A recent Forrester Research survey reports that 45 percent of software profes-sionals now use Agile methods, and many others use portions of the method. 3 1.

The concept of agile development was proposed in 2001 by the agile team, and then many software development teams and companies recognized and accepted it, and gradually been widely used in many projects. Agile software development methods are now being widely used in the IT sector and are increasingly being advocated as preferable to the traditional waterfall development model. endobj Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. Software Process Capability is the range of expected results that are achievable by following the software process. stream Agile family - Agile methods are meant to adapt to changing requirements, minimize development costs, and still give reasonable quality software.
