Research On Cost Management Of R&D Project Of Q Company

With the rapid development of computer science and Internet technology,software R&D enterprises are facing the golden opportunity of development.But the competition between them is becoming more and more intense.Fierce competition has a great impact on small and medium-sized software R&D enterprises.On the one hand,these small and medium-sized enterprises and large enterprises there is a big gap in terms of funding,technical reserves,management and other aspects;on the other hand,software development costs more and more transparent,the development time and cost is often very low due to compression,the enterprise can get profit compared with the previous less.Faced with these changes and challenges,SMEs need to improve their R&D management level and reduce R&D and operation costs if they want to get more profits and improve their core competitiveness.Therefore,how to accurately estimate the cost of the software research and development project and carry out effective cost control are the problems that the small and medium enterprises must consider.In this thesis cost estimation and management of small and medium sized software development enterprise development project as the research object,combined with the domestic and foreign research results,and using cost estimation models and methods commonly used at present,to explore a set of cost estimation and control method suitable for small and medium-sized software enterprises,cost estimation and control in order to guide similar to Q such small and medium sized software enterprises better.Mainly from the following aspects:(1)According to the characteristics of software development project,analyzes the project management and cost management process of software development project,and analyzes the process of cost management and cost were analyzed,put forward the overall framework of cost management.The cost management of the whole management process can be divided into estimation,including planning,budget control,the four main processes of four stages,and the estimation and control is the key and core of cost management and puts forward the cost management of software actually can be used to estimate and control the generalization,only more accurate estimation,in order to provide better control and budget the security cost estimation is the key and basis of cost management,effective cost estimation and control plan can enhance the ability of cost management,software development enterprise cost management is good or bad,largely depends on the cost estimate is accurate.(2)Through the analysis and comparison of several commonly used cost estimation model,find out the estimation model of function point estimation method suitable for small and medium enterprises cost,and analyzes the definition and function point method to estimate the steps,and the advantages and disadvantages are analyzed,and aiming at the defects of function point method,defects the specific measures proposed are analyzed,in order to provide a practical function point estimation method,it is necessary to some characteristics of the system to revise and improve,adjust the adjustment factor.(3)according to the analysis of P petition management system Q's function and resource requirements of function point analysis method in software project management system and put forward the improvement,construct new function point analysis model,and use the new model for the estimation of the petition management system P into the area,the estimated results and the actual investment were compared,according to the comparison results of estimation results compared with the actual situation of accuracy is improved more close to the actual workload.The improved method has important reference significance for the cost estimation and control of small and medium software enterprises.The results of this thesis can enrich the software project cost management system,to provide a convenient and reasonable and accurate estimation method of operation with for the small and medium-sized enterprise class software development software development projects,can be used to better guide the software development enterprise cost estimation and cost control,to improve the enterprise profits and competitiveness.
