Research on Improving Schedule Forecasting Method for Delayed Defense Research & Development Project

Since Dr. Lipke announces earned schedule management(ESM) in 2002, it has been used in project management to make up for the insufficient schedule management function of earned value management technique.However, it is difficult to accurately forecast the schedule of delayed defense research and development(R&D) projects with the ESM technique.Therefore, this paper proposes a new schedule forecasting method considering the progress of delayed work in ESM technique.This concept can also be adopted to the traditional project progress management (PPM) technique.We verify the effectiveness of the proposed concept through several defense R&D projects and prove that it is possible to supplement the schedule forecasting of the ESM and PPM technique.
