Rules of Flow in Manufacturing

Born out of the Theory of Constraints (TOC) come Goldratt UK's 10 Rules of Flow for Manufacturing.

Businesses that implement TOC within their manufacturing operations will see a dramatic increase in output whilst reducing lead-times. Ultimately, implementing TOC significantly improves a business' ability to deliver on-time, in full.

A business management philosophy founded by Dr. Eli Goldratt, TOC aims to achieve breakthroughs in performance quickly. Eli articulated his methodology in a series of books, his first - and most famous - of which being 'The Goal' which became a business bestseller and a staple of university reading lists. 'The Goal' has been publicly endorsed by Times Magazine, Forbes and Jeff Bezos. Its lessons continue to inspire business leaders today.

TOC - Where it all began...

Eli Goldratt – Presenting the Theory of Constraints

In 1984, Eli published his business bestseller ‘The Goal: A Process of Ongoing Improvement’ bringing these concepts to a much larger audience. It follows the protagonist, Alex Rogo, a Plant Manager attempting to save his factory using TOC. ‘The Goal’ became highly influential and is still a staple among business leaders across many sectors.

Eli continued to expand and develop the theory through subsequent books, seminars, and consulting work in client organisations. He presented the Five Focusing Steps which offers a framework to get people started identifying and managing their business Constraints.

Initially focused on manufacturing, TOC was later applied to other areas: project management, supply chain management, sales, and more.

When Eli sadly passed away in 2011, his legacy was continued through his work and his children. Dr. Efrat Goldratt-Ashlag, his daughter, published her book ‘Goldratt’s Rules of Flow: The Principles of The Goal Applied to Projects’ in 2022.

In it, Efrat discusses some of the obstacles to implementing the principles and focuses on the importance of measures in driving the right behaviours. This is a great introduction to Critical Chain Project Management (CCPM) – which is TOC applied to projects.

This inspired a new approach at Goldratt UK. Watch the video (28-minutes) to hear Efrat explain her book in her own words.

Goldratt UK's 10 Rules of Flow for Manufacturing

Taking inspiration from Efrat's book 'Rules of Flow' which applied prescribed rules of flow to project management, Goldratt UK experts set about producing their own rules of flow for manufacturing environments.

And so, the Goldratt UK Rules of Flow for Manufacturing were created. Ten clear, prescriptive rules which can be applied to any production environment to increase output and on-time (in full) delivery.
