Study On The Software Project Management Based On Work Breakdown Structure

Project Management Bode of Knowledge (PMBOK) is the system of project management established by Project Management Institute (PMI) of America. In the guide of the knowledge system, project management is divided into nine kens. They are scope control, schedule control, cost control, quality control, human resource management, communication management, stock management, risk control and integrated management. As far as software project be concerned, scope control is the crucial because it is intractable to the software engineers to fix on the requirement of software system, further more, the product of software project is mainly logical instead of material. Most attention should be paid to the scope control in the software system of project management. WBS (Work Breakdown Structure) is a technique of project scope control, it is used to fix on the scope of project and to estimate the cost and resource of project. The Work Breakdown Structure Responsibility Model that one another unites WBS, OBS and PBS is brought forward which is living to analyze the software engineering regular and the software Capacity Maturity Model ( SW-CMM ). The main angle through the software engineering process of WBS is start off, and PBS is main and carries on the breakdown to the result through the demand depart of customer to the software project, thus the difficult problem that the scope of software project is difficult to certain is resolved effectively. WBS and PBS separately together with the OBS one another unites, thereby causes every demand of every phase of software engineering along with client's every particulars capacity every one form either individual's correspondence, wholly someone is in charge of in the interest of such, and guarantees that the software project meet the demand of consumer successfully. The demand in accordance software process and software product of result ( work package ) that WBSR's pattern is still propose by the software item decomposition analyses such accessibility ( correlation and order relationship ), and the project planning supplies the foundation to formation work package attainability matrix and the one-step attainability matrix in the interest of software. ESSP (Enovation Software Service Platform), the project management system of software enterprise adopts above-mentioned model of WBS which is pruned. Since the actual situation of software project oneself distinguishing feature, OBS is living in the project group directly the homologous individual. At the same time, WBS can divide the project work into the proper size mission, describe the quality being dependent on between the mission, but it is essential to depict the schedule with Gantt chart or Network chart (PERT/CPM) in actual project work.
