The rational unified process rup is an iterative software development process framework created by the rational software corporation, a division of ibm since 2003.
In addition, the work planned for future phases is redefined, if necessary, based on information acquired during the design phase. Project inception is a preliminary phase in most projects to explore the reason for starting a project, identify a solution for implementation, define benefits to be gained upon successful completion, estimate time required to do the project, and request for funds necessary for project execution. Software project management is an art and discipline of planning and supervising software projects. Software configuration management in software engineering. Project planning involves estimating several characteristics of a project and then plan the project activities based on these estimations. The phase at which core architecture is usually implemented.
Software engineering shares common interest with other engineering disciplines. Milestones are markers of project progress that are used in project planning, scheduling, communication and reporting. It is the application of engineering principles to software development. This phase defines the problem that the customer is trying to solve.
