Abstract�� Selecting an appropriate prototype for customized development process will increase development efficiency, decrease development costs and shorten development time. Based on the COCOMO(costructive cost model) II model, a new software cost assessment method was proposed to analyze the influence of the key factors, such as the function differences, system performances and scale, stability, in the development process. The influences of the key factors on the equivalent code, which is essential in the cost estimation formula, were quantified. A practical project shows that the assessment error is about 15%, well within the 40% acceptable threshold in COCOMO II model.
Keywords�� customized development   prototype selection   cost assessment   equivalent code
