Project Time Forecasting: How to Avoid Costly Delays
"Discover earned schedule and earned duration management techniques to improve project planning and keep your projects on track."
In project management, uncertainty and risk often lead to frustrating delays and budget overruns. To combat these issues, accurate project forecasting is essential. Effective project control relies on diligent monitoring of progress, allowing project managers to predict final outcomes and take corrective actions when necessary. Without reliable forecasting, projects can quickly spiral out of control, leading to missed deadlines and financial losses.
One well-known method for monitoring project progress and forecasting both costs and timelines is Earned Value Management (EVM). EVM offers performance metrics for assessing cost and schedule performance. However, traditional EVM primarily uses cost-based metrics, which can be less reliable for schedule performance, especially towards the end of a project. This limitation prompted the development of the earned schedule (ES) concept.
The earned schedule (ES) concept addresses the shortcomings of EVM by providing a way to manage project timelines more effectively. Project time management can be handled with the same methodologies as cost. But ES uses earned value as a proxy to get the duration, which means ES is still cost-based. Earned Duration Management (EDM) eliminates the drawback; EDM is a method developed to fix the problem. This article delves into how ES and EDM can enhance project time forecasting, helping you stay proactive and avoid costly delays.
What are Earned Schedule (ES) and Earned Duration Management (EDM)?
Earned Schedule (ES) is an extension of Earned Value Management (EVM) that focuses on monitoring schedule progress in time units rather than monetary units. Since EVM key metrics are cost-based, ES was developed as a time unit extension. Earned Schedule indicates the time at which the current earned value was planned to be earned. By converting earned value into a time-based metric, ES provides a more intuitive and reliable way to track project timelines.
- Metrics: ES uses cost-based metrics converted to time, while EDM uses duration-based metrics.
- Focus: ES focuses on the time at which work was planned to be completed, whereas EDM focuses on the amount of work completed in terms of time.
- Independence: EDM is independent of cost structures, providing a pure measure of schedule performance.
Making Time for Project Success
By using composite performance factors and understanding project characteristics, project managers can significantly improve the accuracy of their forecasts. Whether you choose to implement earned schedule or earned duration management, these techniques provide valuable insights for staying on track and achieving project success.
