Scrum (Software Development):- In English SCRUM means “an ordered formation of players in which the forwards of each team push against each other with arms interlocked”. Scrum is an iterative and incremental agile software development framework for managing software projects and product or application development. Its focus is on a flexible, holistic product development strategy where a development team works as a unit to reach a common goal as opposed to a traditional, sequential approach. Scrum enables the creation of self-organizing teams by encouraging co-location of all team members, and verbal communication among all team members and disciplines in the project. A key principle of Scrum is its recognition that during a project the customers can change their minds about what they want and need (often called requirements churn), and that unpredicted challenges cannot be easily addressed in a traditional predictive or planned manner. As such, Scrum adopts an empirical approach—accepting that the problem cannot be fully understood or defined, focusing instead on maximizing the teams ability to deliver quickly and respond to emerging requirements. Characteristics of SCRUM methodology are : The first and last phases (Planning and Closure) consist of defined processes, where all processes, inputs and outputs are well defined. The knowledge of how to do these processes is explicit. The flow is linear, with some iterations in the planning phase. The Sprint phase is an empirical process. Many of the processes in the sprint phase are unidentified or uncontrolled. It is treated as a black box that requires external controls. Accordingly, controls, including risk management, are put on each iteration of the Sprint phase to avoid chaos while maximizing flexibility. Sprints are nonlinear and flexible. Where available, explicit process knowledge is used; otherwise tacit knowledge and trial and error is used to build process knowledge. Sprints are used to evolve the final product. The project is open to the environment until the Closure phase. The deliverable can be changed at any time during the Planning and Sprint phases of the project. The project remains open to environmental complexity, including competitive, time, quality, and financial pressures, throughout these phases. The deliverable is determined during the project based on the environment.
