| Fast development of information technology, improving of the human resources cost, intensified competition in the industry, continuous improvement of individual needs, and multiple factors, huge impact on traditional software industry. China’s software industry after nearly 20 years of development, has entered the era of meager profit. The amount of software project contract fell sharply, which forced the traditional software companies to increase profits by reducing costs.This thesis, takes the traditional software company LH as the research object, analyzes the company’s internal organization structure, operation mode, from the overall point of view to understand the problem of cost management. By analyzing the present situation of software project cost management, the five problems of LH company’s software project cost management are summarized, including the organization structure is not strong, the project team’s cost consciousness is weak, the cost management related process and system is not perfect, the cost estimation model is not perfect, and the cost control system is not perfect. To adjust the overall structure of LH company, optimize the cost management system and process. The project cost is divided into fixed cost and human resources cost, the use of WBS method the software project is divided into different work packages, function, the use of Delphi expert estimation method obtained each work package, function of consumption and hours of work, the preparation of a software project cost estimation benchmark, a software project cost estimation system based on. Organize cost management training, improve employee cost consciousness. In the project to promote the process of the actual amount spent on fixed cost control; in accordance with the Gantt chart of data collection, using the earned value method to analyze the deviation of the actual expenditure and the estimation of the amount of, in order to make adjustment in real time, to achieve the control of human resource cost. After the completion of the project phase and the project as a whole, the overall calculation of the project. Analysis of the internal and external factors that affect the cost control, and give the corresponding measures. Construction software project cost assessment system based on cost control results. Finally, the research results are verified by the actual case.Cost control is very important to enterprises. This thesis is a research on the cost management of LH company. This thesis attempts to establish a standardized software project cost management model, including cost estimation system and cost control system, which provides a reference example for small and medium sized enterprises in China. |
