The Lean Lego Flow Simulation is a staple of any Lean training library. It is designed to help people see the benefit of flow over batching in a non-threatening environment.
Trainees will be assigned to work stations where they will build a small Lego model. A material handler will transport batches, and other trainees will act as waste observers.
This is a fun, engaging activity that will help you convert your team to Lean thinking.
In this Lean simulation, teams will build the driver's consoles for our Vel-ActionKart, a fictional product.
They will start with batches of 6 units, then progressively reduce the lot size to 3 and finally single piece flow. They will then implement a handful of kaizen (continuous improvement) ideas to streamline the single piece flow.
During each production run, the instructor or assigned team member will collect data on a handful of metrics-lead time, work-in-process, productivity, etc.
In the end, teams should see an improvement each time the lot size is reduces, with a substantial improvement once the kaizen for one piece flow is completed.
Our Lean Lego Flow Simulation is a training tool designed to show the benefit of Lean and one piece flow. It walks trainees through the process of reducing batch sizes from 6 to 3 and then to 1. It follows this up with an additional round or two of kaizen activity. In the first round, they simply move the work stations close to each other in a 'cell' orientation. In the second kaizen round, they are allowed to make any additional changes they want.
The goal is to highlight the benefit from simply reducing inventory in a system, as well as some other key Lean concepts.Key Concepts Addressed in this Exercise
