Our mission is to help individuals and organizations around the world to make better, faster decisions when it really matters by developing the most innovative and easy-to-use range of decision support apps.

We have an incredibly passionate team at Goldratt Research Labs who develops the Range of Harmony Apps.

Dr. Alan Barnard

Dr. Alan Barnard is one of the world’s leading Decision Scientists and Theory of Constraints experts. He is CEO of Goldratt Research Labs and works with Fortune 500 companies and the UN, government agencies, and NGOs.

At Microsoft, Alan’s ground-breaking system redesigned the company’s supply chain and saved Microsoft a quarter of a billion dollars, and increased sales by hundreds of millions of dollars within the same financial year.  Microsoft’s CTO Robert Meshew described the result as “nothing short of remarkable.” 

Over the last 20 years, Alan and his research lab developed a new method for making better, faster decisions and field-tested it with individuals and organizations around the globe. The five-step system known as the “ProConCloud method” capitalizes on the latest insights from Dr. Barnard’s research on why good people make and often repeat bad decisions and the disruptive questions that can help some discover and overcome the limiting beliefs behind their bad decisions.


Jaco-Ben is VP of Technology at Goldratt Research Labs. He has extensive experience in delivering end-to-end supply chain simulation projects to support supply chain and business transformation projects, including five years of relevant experience in senior positions with BHP Billiton. He brings a deep understanding of simulation modeling and Theory of Constraints best practices in supply chain and operations management. Jaco-Ben holds a BSc in Industrial Engineering and a MSc in Simulation.

She was introduced to the Theory of Constraints while she was studying and was immediately captivated. She did her final year project in collaboration with Goldratt Research Labs about inventory management, titled “Determining the boundary conditions of various inventory management policies using simulation.” After completing her degree, she joined the Goldratt Research Labs team, where she is involved in digital marketing and simulation modeling.

Ana Maria Conde

Ana Maria is a passionate educator, international trainer, and coach. She has worked worldwide teaching people thinking and problem-solving tools, becoming a TOC thinking process expert. Ana decided to follow up with her professional studies in anthropology and graduate studies in education and neuroscience applied to educational contexts. Following the purpose of making the Harmony Decision Maker App accessible for a bigger audience, she brings her knowledge and abilities to the group. She also coordinates and executes the Odyssey program, coaching people to make better decisions when needed.

Bethelle McPherson

Bethelle is a serial entrepreneur, award-winning speaker, and technical arts designer. She specializes in graphic design, web development, and social media marketing. With the goal of introducing the Harmony App suite to a younger audience, Bethelle brings her wealth of skills and multicultural background to the team. Bethelle met Dr. Barnard at a business conference in 2019 and joined the Goldratt Research Labs team in early 2020. Besides the constant pursuit of knowledge, Bethelle’s greatest passion is creating a happier and healthier world through her company, Happy Life Results, LLC.

Teo Branzell

Teo is the youngest member on the team; his biggest passion is to help identify problems and develop simple and practical solutions.
Teo first met Dr. Alan Barnard when he interviewed Alan for his podcast series, “Social Media Branded.”
He now works closely with Dr. Barnard to develop and implement different marketing strategies to help reach more people who want to make better, faster decisions when it really matters.
