Case Study - Improving Fuel Quality by over 95% via 6 Sigma, generating $5,000,000 extra production


A large mine was suffering significant equipment downtime, reducing production by about $5,750,000 per year, due to dirty fuel.

1. We sampled fuel each day

To understand the actual quality of the fuel.

2. We plotted the results

On a Process Behaviour Chart to understand whether the problem was systemic or not, as that determines how a problem is most effectively and efficiently addressed.

3. We identified and addressed systemic causes

To remove them from the process and prevent their recurrence.

4. We continued to measure and act whenever non-systemic problems occured

To ensure the changes were improvements, and were sustained.

5. Result

Fuel Quality improved from > 300,000 ppm to < 2,000 ppm, generating over $5,000,000 per year in production no longer lost due to dirty fuel!


Delivery to Plan


Fuel Quality Improvement


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.
