Abstract: To solve the poor accuracy and the low operability on the flexible point change impact range measurement of the flexible software,a flexible change model was proposed,the flexible point change propagation impact graph was established,the unction point analysis method was improved and a quantitative measure model of flexible point change impact range was proposed by taking the user-oriented flexible point as the research object.In this measure model,the flexible change components were taken as the basic software metric entities,the flexible points,the flexible change points and the flexible change items were expressed by using the flexible change model.The impact of the flexible point change propagation was analyzed by using the flexible change propagation impact graph,and the flexible change components influenced were extracted by using the improved function point analysis method.Through calculating the function point counts of flexible change components,the flexible point change impact range was determined.In addition,an example was given to illustrate the quantitative measure process of the flexible point and analyze the flexible point change impact range.
