Earned Schedule Plus

Earned Schedule Plus (ES+) is intended for project managers, engineers and performance analysts
that is, those who use Earned Value Management (EVM) with Earned Schedule (ES) for the purpose of project control.

ES is an extension to EVM providing the capability of time-based management and control of schedule performance. After several years, tagged as an emerging practice, ES is now normalized to EVM with its inclusion in the Project Management Institute Practice Standard for Earned Value Management, and notably, in the International Standards Organization publication, ISO 21508:2018, Earned Value Management in Project and Programme Management.

ES+ introduces analysis methods developed since publication of the Earned Schedule book in 2009. Along with the new methods, there are chapters on the need for measures of project performance, the origin and history of Earned Schedule, and the studies establishing the reliability of ES duration forecasting.

The new and enhanced methods presented in ES+ include advances in

- Project duration forecasting

- Assessing project recovery

- Measuring the impact of rework on project cost and duration.

The developmental research is included along with application examples to promote understanding and encourage use. Applying the advanced ES practices described in this book will significantly benefit project managers in their efforts to achieve successful projects.
