Based On COCOMOⅡ Model’s Case Study On The Valuation Of HX Software

With the rapid development of information technology, computer software has been widely used in all aspects of daily life. Both in the product market or in the capital market,computer software transactions are becoming more mature and standardized,true and accurate assessment of the value of computer software have been valued by more and more people.Computer software has three commonly assessment methods,namely,cost method,income method and market comparison method. Foreign evaluation industry started earlier, has made a greater development now after many years of research and exploration in the field of software valuation. However, China’s research in the field of the computer software valuation is still in the initial stage of development, which is relatively late compared with the developed countries and has few research results. In China, when using cost method to evaluate the value of software, usually analysis and study the foreign software cost estimation model firstly, and combined with the characteristics of China’s software industry to modify the model, in order to improve the accuracy of the evaluation. At present, the COCOMO model is the most widely used software cost estimation model, which is proposed in the 1980s and based on the foreign software environment at that time. Therefore,When China’s software industry using this model,it is necessary to consider the current development of China’s software industry and revise it, and to meet the characteristics of China’s software industry.The article combines the specific computer software case, using the cost method and the COCOMOⅡ model to evaluate its value. Firstly, it introduces the model of using cost method to evaluate the value of computer software and software cost estimation model COCOMOⅡ. Secondly, it evaluates the value of the case software by using the cost method and the COCOMOⅡ model. Thirdly, combining with the progress of software industry, analyzes and modifies the factors that affect costs of the COCOMOⅡ model to make it more suitable for China’s software value evaluation. Finally, the modified COCOMOⅡ model is used to evaluate the value of the case software, the results of the two models are compared and the reason of the error is analyzed.
