Goldratt Research Labs (GRL) was founded in 2007 by Dr. Alan Barnard, on request
of Dr. Eli Goldratt, the creator of Theory of Constraints (TOC), to create a research
organization that would be a spearhead for new Theory of Constraints based research
and development to help accelerate and test the ever growing TOC body of knowledge.
GRL focuses on developing research partnerships with especially the more complex
private and public sector organizations to find innovative and sustainable ways
to achieve more of their goal units, in less time with the same or less resources.
We employ a robust research methodology that starts with:
Quantifying the extent and system wide consequences of problems,
Identifying and validating root cause hypotheses,
Developing viable win:win:win solutions in collaboration with key stakeholders to
identify all the necessary and sufficient changes to achieve the desired level of
performance as well as the best sequence of implementation in the form of a Strategy and Tactic tree
Testing and continuous improvement of these solutions through "proof-of-concept"
To ensure sustainability of changes and continuous improvement GRL provides experienced
TOC experts - all certified by TOCICO
Audit the implementation of recommended changes to pro-actively identify and overcome
unexpected implementation obstacles; and
Assist organizations and their IT partners in implementing these TOC best practices
within their IT systems.
Since the start of the development of Theory of Constraints over 30 years ago, there
have been thousands of successful TOC implementations in almost every industry and
application imaginable. The “Theory of Constraints Handbook”, published by McGraw
Hill in 2010, provides an overview of the incredible scope of TOC applications today.
These do not only include manufacturing, distribution and project based organizations,
but also service-based organizations, city councils, schools, hospitals and even
We believe that despite the great successes already achieved, we are only now ready
to discover the full implication and application of managing and improving systems
holistically by managing system constraint(s), and the importance of understanding
the human aspect of such a change. Considering the continued exponential growth
in population and complexity of the world we live in, we believe that the most significant
contribution of TOC over the next 30 years will be its application to help us to
better exploit (and not waste) our scarcest resources - our finite natural resources
and on a personal level, our limited time, attention and motivation - wasted by
doing the many things we should not do and not doing the few things we should.
As a research organization, we want to contribute to advancing the application of
existing TOC knowledge to more fields and to develop new TOC knowledge to help individuals,
organizations and governments better manage these scarce and finite resources for
the benefit of all.

Dan Klarman, TOC Expert Israel
Dan acquired a Master’s degree in Physics from Tel-Aviv University and held several managerial positions in various fields (including the military, education, R&D and security) before plunging into the world of TOC to become a consultant.
In 2010 Dan started freelance work for Goldratt Research Labs and joined officially in 2012. In this role he has facilitated training and improvement initiatives with organizations that include the State of Utah, Random House Publishing, SAP, Tata Steel and others, and have assisted in numerous TOC Odyssey programs around the globe. Dan collaborates on development and implementation for Harmony Software.
He has accumulated experience in teaching and implementing TOC processes and enjoys seeing people make major breakthroughs for themselves and realize the vision they have for their organizations. His focus strengths include special implementations of DBM and S-DBR, as well as using TOC for value add in ERP implementations.
Paula Weyler, TOC Expert California, United States
Paula began her journey into Theory of Constraints in 2007 as a TOC implementation manager for a medium-sized custom manufacturing firm in the US. Working with Goldratt Consulting, she led a team to implement S-DBR in an environment that required the testing and development of new TOC knowledge. After securing dramatic improvements in operational performance, which yielded both on time delivery and quality over 95%, she was promoted to VP of Sales and Marketing for the firm. In this role, she used TOC sales processes to double sales in 3 years.
During this time, she also participated in the annual TOC Odyssey program to apply the Thinking Processes to the personal lives of participants.
Paula is passionate about using TOC to dramatically improve both her clients’ lives and the performance of their organizations.
In 2012 Paula joined Goldratt Research Labs, one of the leading organizations in developing and testing new TOC knowledge. In this role she has facilitated training and improvement initiatives with organizations that include the State of Utah, Random House Publishing, and SAP. Her training workshops help clients realize their visions for significant growth and improvement, while creating harmony in the organization. She also facilitates new development, marketing, training and implementation of Harmony Software.
Dr. Barry Morgenstern, TOC Expert Connecticut, United States
Barry holds a PhD in Special Education and Applied Behavior Analysis. He is a Board Certified Behavior Analyst who trains teachers, parents, and therapists to work with children with autism and other developmental disorders. He has 20 years experience in a wide variety of settings and is currently the CT Director of Research for The Institute of Professional Practice.
His current research interest focuses on testing the extent that the Theory of Constraints can improve services for children with autism.
He has worked with TOC at the International Odyssey Program, as well as applications for the State of Utah.
Dr. Filippo Pescara, TOC Expert Italy
Filippo Pescara is a doctor in electronic engineering (from University of Ancona) and he holds an MBA in managerial engineering from Polytechnic of Milan. His interest in TOC started in 1993 when he read the goal for the first time. He’s a TOC practitioner since 1995.
Filipo engages in both consultancy and educational projects. He works on holistic projects in medium sized companies in Italy and cooperates with industrial associations and universities holding conferences, educational projects and seminars.

Elsabe Jean Pieters (Elbie). Pr Eng(Industrial), PMP South Africa
Elbie has spent the majority of her career in the FMCG environment in various senior manufacturing and IT management positions in leading FMCG companies such as SABMiller and PG Group that gave her the opportunity to manage some of the largest Manufacturing IT projects and managing and maintaining a few of the biggest production and packaging lines in the industry. During her time as Manufacturing manager, she also acquired extensive technical and planned maintenance best practices experience in for example the latest manufacturing and packaging technologies.
Elbie has a Industrial Engineering degree from the University of Pretoria (South Africa), is registered as a Certified Professional Engineer at Engineering Council of South Africa, is a PMI accredited Project Management Professional and has a Blackbelt in Six Sigma. Over her career, she has had the opportunity to apply Theory of Constraints best practices and thinking in many production, distribution and maintenance environments. For example, in 2009 she had the opportunity to lead a large TOC implementation project for a major motor component manufacturing plant working with Dr. Alan Barnard from Goldratt Research Labs, where they achieved a 50% reduction in Working Capital while increasing availability and throughput substantially resulting in a 90% reduction in order backlog within just 4 months.
Elbie recently joined Goldratt Research Labs and enjoys working on very complex problems around the globe, working with integrated teams and using a structured approach and tool set and her project management background to analyze systems, quantify improvement potential and develop and implement best practices and systems that add “Real” value.
