Duration Forecasting Capability of Critical Path-Focused Earned Duration Management.

Project management aims to evaluate a project's cost, schedule, and technical performance to deliver the best product or service at the lowest cost and within the shortest timeframe by enhancing a balance between cost, time, and quality of the work objective. Earned Duration Management (EDM) in project time monitoring and forecasting focuses solely on timerelated factors to achieve the objectives. However, many studies state that for projects with multiple parallel activities of varying durations, the earned duration factors/indicators could not provide significant forecasts about the critical-path job details of the project. The Critical Path focused Earned Duration Management (CP-EDM) technique has been introduced to enhance this. This study compares EDM and CP-EDM techniques on 69 real-life construction sector project data to evaluate the efficiency and accuracy of project duration forecasting. The results have showed that 69.56% of cases had better results by applying CP-EDM, demonstrating that focusing on the critical path instead of the entire project enhances the accuracy of project duration forecasting.
