| With the rapid development of the information technology industry,software industry,labor costs and resource use costs more and more high,the software industry is becoming more competitive,the personalized needs of customers on the software products continue to improve,the combination of these factors,the traditional software industry suffered a great impact.China's software industry has 20 years of development,now the software industry profits greatly shrink,software development projects in more than the contract price was greatly reduced,but there are a variety of discount,so the traditional software enterprises to reduce the cost of development,to ensure the software development project profit upgrade.This paper takes the L group as the research object,firstly introduces the project management,cost management,software development,software development project management,software project cost estimation and software development project cost control concept.Secondly,it studies and explains the current situation of software development project cost management at home and abroad.Then the parameter values will be listed and given the accuracy of the model is higher today in software development project management and software development project mature cost estimation model,and then introduced the related software development project cost control.Secondly,the COCOMOO model is used to calculate the cost estimation value of the COCOMOO model in the traffic network management system of L group.After the comparison of the estimated value and the actual cost,through the study of various types of documents and listen to the views of many,the numerical differences are summarized and analyzed.Finally,write my research can help other enterprise software development software project cost estimation and cost control work done better,which can help enterprises to reduce software development costs,improve its profit margins,in today's intensive software enterprises in talent shows itself. |
