The primary goal of the systems engineering is the creation of a setof high quality products and services that enable the accomplishment of desiredtasks and needs of the clients or user groups. A typical systems engineering projectcan be divided in to three phases: definition, development, and deployment. Thedefinition phase involves the activities of requirement elicitation and refinement.By the end of system definition phase, we have all the system functional and nonfunctionalrequirements. One of the results of development phase is initial workingmodel of the system. The deployment phase consists of activities of operationalimplementation, operational testing and evaluation, and operational functioning andmaintenance. In a project life cy...
