What arer the phases of a project development cycle give the salient tasks under each phases?

Answer 1

Software development is achieved through collection activities that lead to the building of a software product. Software development is traditionally divided into various phases, which we describe briefly in the following sections.

Requirement Phase:-

The development process usually begins when the client approaches a development of organization in regard with a piece of software, with the opinion of client to the profitability of an enterprise. The task of developer is to determine exactly what the client needs and find out their cost and deadline of software. Software development is an expensive process.

Specification Phases:-

The requirement must be understood by the developers, when client agrees; the specification document is drawn by the specification team. In the specification document, the functionality of the software is described. The specification document of the software is part of contract, where as contract software development can lead to a lawsuit, the document should be written as evidence.Planning Phase:-The plan describes the software process in detail, and also it includes structure of development organization, project responsibilities, technique, managerial objective etc to be used. Detail schedule, budgets and resource allocation are also made. In planning duration and cost estimation are important.Design phases:-The design phase is to determine how the software works. With specification document, internal structure of the software is determines by the design team. Algorithm, Architecture design, data design, data structure are made in this phase. The major output of design phase is architectural design and detailed design.Implementation Phase:-The various modules of the design are coded in this phase. The major documentation is associated with implementation is the source code itself, but the programmer should provide additional documentation to assist in maintenance. All test cases against the code was tested for the actual and expected outputTesting phase:-In this phase modules combine and determine whether the software works correctly or not. All modules are integrated in a specific order for the critical influence on the quality of software. The purpose of integration testing is to check that modules combine correctly, so that it achieved task and satisfies the specificationMaintenance Phase:-Maintaining and enhancing software to cope with newly discovered problems or new requirements can take far more effort than the initial development of the software. Not only may it be necessary to add code that does not fit the original design but just determining how software works at some point after it is completed may require significant effort .The software has been hand over to client and changes as a part of maintenance.
