Abstract
We often manage progress by the number of completed programs in the coding and unit test process of large-scale software development. Usually, the graph of progress draws an S-curve that tends to be late. Terefore, it is difficult to judge only by the graph of progress whether the project proceeds favorably or not. To solve this problem. we investigate the progress data of real large-scale project that contains five teams and the condition of actual site. Eventually, we disocvered different characters in working and significant changes of productivity according to "begin", "middle" and "end" of the coding and unit test process. From this investigation, we propose "the four divided process control method" that divide the coding and unit test process in four divisions. Using this way of thinking, we can manage a long and monotonous prodess more securely by new control items of each division. And, we discuss the estimation of personnel number in coding and unit test process using "the four-divisons management"
