Harmony Change Simulators

Test BIG CHANGES with LOW RISK and LOW COST. Designed to help managers quantify the impact of any change on their organization.

Hannah’s Shop

An interactive simulation game for learning how to reduce shortages and surpluses in a supply chain.

Maintenance Depot

A dynamic simulation model designed to answer two simple but important questions about variability and push and pull execution rules.

Gas Station Simulation

A simple simulation that illustrates how difficult it is to predict the impact of decisions on an interdependent​ system.

Dice Game

A simple example of the how difficult it is to predict the impact of change even on simple systems.

Mining Supply Chain

How does Theory of Constraints work in area of inherent variability like mining? Find out in the Mining Supply Chain Simuation.

Project Management

Goldratt Project Management Simulation is a dynamic simulation model that was designed to answer three simple but important questions.

Managing Flow

A customizable simulation model that allows you to explore the impact of Theory of Constraints (TOC) planning, execution and continuous improvement rules will have on the performance on various types of environments.

Supply Chain Digital Twin

Harmony Change Simulators

Hannah's Shop

An interactive simulation game that helps you answer and explain two simple questions within inventory management:

Why do traditional inventory management rules result in avoidable shortages and surpluses ?

​Can demand-driven inventory management rules significantly outperform the traditional rules … and if so, by how much?

Maintenance Depot

A dynamic simulation model designed to answer 2 simple but important questions:

1) Can we predict the impact of variability on a system?

2) How much better can we do if we change from PUSH to PULL based planning and execution rules.

Gas Station Sim

A simple simulation that illustrates how difficult it is to predict the impact of decisions on an interdependent​ system

How will the service type offered to customers impact the financial and operational performance of a simple gas station?

Dice Game

A simple example of the how difficult it is to predict the impact of change even on simple systems.

The Dice Game simulates a factory with 5 machines whose output is dictated by the roll of a dice. Using different systems you can see how the output of the factory is affected.

Project Management

Goldratt Project Management Simulation is a dynamic simulation model that was designed to answer three simple but important questions:

  1. What will likely be our completion date, due date and financial performance for a portfolio of programs if we keep using traditional project management rules for planning and execution?
  2. How much better can we do if we are willing to change the rules to Theory of Constraints’ Critical Chain Project Management (CCPM) rules?
  3. What CCPM rules will provide with the simplest, fastest and lowest risk way to achieve the best operational and financial results?

Managing Flow

A customizable simulation model that allows you to explore the impact of Theory of Constraints (TOC) planning, execution and continuous improvement rules will have on the performance on various types of environments.

You can choose between the following types of environments: Operations, Projects, Services, Maintenance and Back Office.

Mining Supply Chain

How does Theory of Constraints work in area of inherent variability like mining? How do you align an entire supply chain and convert from a PUSH based system to a PULL? 

Find out in the Mining Supply Chain Simulation.
