Systems Requirements

Requirements: It explains as to raise asked for of the interested people (' ' stakeholders' ') to transform them into a set of requirements that the products function in the scope of the system to be constructed and supplies requisite detailed what it must make sistemAnlise and Design: Sample as the system goes to be carried through, of form that the same executes the tasks and functions specified in the descriptions of the use cases created, and that it fulfills to all the preset necessities, and steady when changes of the requirements occur funcionaisImplementao: It defines the organization of the code, in terms of in layers organized subsystems of implementation, implements classrooms and objects in terms of components and carries through tests in the developed components as unit, beyond integrating the results produced in executable systems. Test: It verifies the interaction between objects, the adequate integrity of all the components of software and if all the requirements had been implemented. Also it identifies and it guarantees that the defects are corrected before the implantation of software, reverse speed-analyzed and locked up. The Rational Unified Process considers an iterative boarding, what it means that the project must be tested all. This allows to find defects how much so early possible, what it reduces the cost radically to repair the defect. The tests are carried through throughout four dimensions of the quality: trustworthiness, functionality, performance of the application, and the performance of the sistemImplantao: Systems are carried through through the application of components. If you have additional questions, you may want to visit Sean Rad. The process describes as the reutilizao of existing components or to implement new components with well definite responsibilities, becoming the system most easy to keep and to increase the reverse speed-use possibilities.
