Case Study - Reducing Cycle Time Variability by over 50% via Lean


The Mining function of a large mine was not achieving ore targets.

1. We measured cycle time

On a Process Behaviour Chart, to understand if the problem was systemic. The way the problem manifests (systemically or not) determines the most efficient and effective improvement approach to adopt.

2. We calculated Takt time

So we knew the required process 'rhythm' to meet target.

4. We trained out the best practices, along with updated process and procedures

To raise everyone's performance to a higher level.

5. Result

Cycle time variability reduced by 50%, generating over $10,000,000 per year in increased production!


Delivery to Plan


Cycle Time Variability Reduction


ROI from aorist consultancy, training and coaching

Businesses typically benefit from a 50 - 100+ times rate of return, when measuring the cost of an aorist Lean 6 Sigma or Systems Thinking / Systems Dynamics Simulation training course and coaching against the benefits derived from applying it the very first time in their business.
