A process evaluation device, comprising: a development process definition storage unit which stores definition information on a plurality of processes for developing software and sequence numbers thereof; a transition information acquiring unit which acquires identification information or a sequence number of a new process after a backward transition occurs, wherein a process transition from a certain process referred hereafter as an evaluation origin to said new process is said backward transition when a sequence number of said new process is smaller than a sequence number of said evaluation and a transition information analysis unit which calculates and thereby outputs a backing-away distance which is a difference between a sequence number of said evaluation origin and a sequence number of said new process, is provided, in order to apprehend what are real causes of the development delay.
