Two books are now available:       

Earned Schedule overview: This book is intended for those who use Earned Value Management (EVM), including project managers, engineers and performance analysts.  Earned Schedule (ES) is a significant enhancement to EVM, extending its cost-based features to the management and control of schedule performance.

Earned Schedule Plus overview: 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, and measuring the impact of rework on project cost and duration.

Both books may be ordered in paperback or e-book formats from sources such as Amazon and Barnes & Noble.
