PROGRESS PREDICTION METHOD, PROGRESS PREDICTION DEVICE, AND PROGRESS PREDICTION PROGRAM FOR PROJECT
[TASK] To make it possible to predict, at an intermediate point of a step in an ongoing project, a progress including subsequent due dates with simple processing. [SOLUTION] A progress prediction method for a project including at least one step includes: acquiring data of a progress plan including a progress level of the step and an execution timing corresponding thereto; acquiring data of progress performance including a progress level of a completed part of the progress plan and an execution timing corresponding thereto; calculating, based on the data of the progress performance, a performance period from a reference time point of the step to a predetermined time point at which a predetermined progress level was achieved; calculating, based on the data of the progress plan, a plan period from the reference time point of the step to a time point at which a progress level same as the predetermined progress level is achieved; calculating, based on the performance period and the plan period, a progress evaluation index regarding progress of the step; and predicting, based on the progress evaluation index, data of the progress performance after the predetermined time point.
