2023 - Earned Schedule 20th Anniversary Event

 8th March 2023 - World-wide Access

Home > History > 2023 - ES Special Event

20th Anniversary International Webinar Program:

ES-Logo.jpgMarch 2023 was 20 years after the publication of the seminal paper Schedule is Different, in The Measurable News. This was the paper that introduced the concept of Earned Schedule to the world. 


Earned Schedule (ES) is a breakthrough analytical technique that resolved the inability of Earned Value Management (EVM) to predict the project completion date.  It is derived from, and is an extension to, EVM that uses normal EVM data.  But, in contrast to the cost-based indicators from EVM, the ES schedule performance indicators are time-based, and provide a status and predictive ability for schedule outcomes, analogous to the facility for cost status and cost predictions when using traditional EVM. For more on how ES works and to download the free tools, visit the ES Home Page.  


This 20th Anniversary Webinar, held on 8th March 2023, showcased the value of ES as an extension to EVM, the enhancement and developments of the last 20 years, and considered the way forward. Our presenters listed in the program below are Earned Schedule experts, drawn from around the world, representing a diverse range of industries.

1. Earned Schedule, 20 years of innovation, past – present and future

Walt Lipke

Walte Lipke.jpgAbstract:
Earned Schedule is a significant enhancement to Earned Value Management (EVM). From its beginnings, practitioners of EVM have desired a methodology for controlling both cost and schedule performance. Earned Schedule enables that integration, which likely explains its extraordinary propagation and uptake around the world.


ES is a simple idea; though, over time it has evolved to complex methods for analyzing schedule performance. In his presentation, Walt will discuss the origin of Earned Schedule, its dependence upon EVM, and its extensive schedule analysis capabilities. He will wrap up the session with a few words concerning the future foreseen for ES.

2. Validating Earned Schedule, the research and studies

Kym Henderson

Introducing a new concept into the realm of project controls is challenging. This presentation will outline the studies and research undertaken to validate the reliability of Earned Schedule's predictions and some of the challenges and controversies that had to be overcome. The conclusion to be drawn from this extensive body of work is that Earned Schedule's time predictions are similar in accuracy to Earned Value's cost predictions making ES a valuable addition to the project controls toolset.

4. Act Fast, Think Fast: Agile Schedule Performance

Robert Van de Velde (Canada)

Agile practitioners face a dilemma: they want to act fast but must think slow. Without reasoned decisions on what to do and when to do it, systematic errors in judgment are inevitable. Earned Schedule offers a way out of the dilemma. It leverages data already available on most Agile projects to provide insights into schedules and how they perform. Unlike familiar Burn Charts, Earned Schedule metrics directly measure time performance and signal when action is needed. In short, Earned Schedule gives Agile projects a way to act and think fast to improve schedule performance.


Brief Bio:
Robert Van De Velde, Ph.D. is a project-management practitioner. In the past 35 years, he has served as PM or PMO-lead on over two dozen projects and programs. They have ranged in size from six to nine figures and have been completed in domains from business to government.

Committed to improving his practice, Rob has continued to study project management. In 2007, he discovered Earned Schedule, and in 2014, he became an Agile Scrum Master. As Rob’s practice focuses on time-critical projects, he’s had plenty of opportunity to use both techniques.

During his studies, Rob worked out the math for combining Earned Schedule and Agile. He adapted the techniques to one another and iteratively implemented and upgraded the approach. Rob shares his knowledge and experience through a blog (earnedscheduleexchange.com), vlog (earnedscheduleacademy.com), professional journals, and, increasingly, through posts on LinkedIn groups, hashtags, and his company site.

5. Research on a categoriser to enhance expected project 

     duration forecasting performance using ES

Paulo André de Andrade (Brazil)

The presentation will provide the attendants with a summary of the work done in bringing Earned Schedule to the Brazilian project management community and an overview of the PMB Limits Categoriser (PLC) concepts and results.

Project managers need to understand which characteristics a project should have to enable a good performance on its duration forecast. Currently, the most known method is the topological analysis of its network, commonly called serial/parallel indicator. However, the newer project regularity indicator recently outperformed the serial/parallel indicator in predicting the accuracy of project duration forecasts. The latest development in this field is the PLC, a novel project regularity indicator created in 2022, provides better results than existing categorisers.


Brief Bio:
Paulo works, since 1995, as a consultant in project management. He graduated in Electronic Engineering from Instituto Tecnológico de Aeronáutica (ITA-1968), holds an MBA in Project Management from Fundação Getulio Vargas (FGV-2008) and got his PMP certification, in 2009, by the PMI. Paulo worked at IBM Brazil (1971/95) as Engineer and as manager of Engineering. hardware development, business development and software products. During 1972 to 1975, he went to Germany and the USA to work on technology transfer projects. IBM hired him from 1997 to 2004 as manager of the modernisation of Banco do Brasil branch offices software environment. From 2010 onwards, Paulo explored and disseminated the Earned Schedule technique in Brazil. Walt Lipke commissioned him in 2013 and 2020 to translate and market his books "Earned Schedule" and "Earned Schedule Plus". In 2016, Prof. Mario Vanhoucke invited Paulo to research project schedule control and forecasting techniques. Paulo coordinated for the Brazilian Association for Technical Standards (an ISO member) the development of its Project Performance Management Guidance. He published papers and created the PLC, a novel ES-based project categoriser to improve the expected accuracy of project duration forecast.

6. A 20-year academic research journey summarized in one presentation

Mario Vanhoucke PhD

Mario V.pngAbstract:
Project management with earned value and schedule control has long remained outside the field of academic research, but that all changed with the introduction of the earned schedule concept in 2003. What was initially a collaboration between two friends in Belgium, quickly grew into an intense journey with people all over the world (including Walt Lipke). In 2011, I was awarded a 1.3 million euro research grant to explore the concepts and extend them to more advanced methodologies, including statistical and analytical project control using EVM/ES. The Operations Research & Scheduling group in Belgium now has 20 PhD students working on academic research studies in this exciting field. The presentation will provide a full summary, without too many technical details, of the journey that began 20 years ago with an article in the Measurable News, and has since culminated in more than 5 doctorates, an empirical database of 180 projects and +20 peer-reviewed articles in flagship journals on this exciting field of research.

8. Do You Trust Your IMS? (Earned Schedule vs. Traditional IECDs
      in a forecasting accuracy showdown)

Yancy Qualls

An IMS can forecast almost any outcome…on paper. Independent Estimated Completion Date (IECD) formulas use past performance to objectively predict future completion dates. IECDs can then be compared to the forecast in the IMS to either support or challenge the accuracy of the IMS. But there are many IECD formulas. Which ones are the most reliable?

During this session, we will simulate 1000’s of project outcomes to see how IECD formulas based on Earned Schedule indices stack up against more traditional IECDs.
