A large gold mine was experiencing significant levels of tyre damage, leading to early tyre failure on dump trucks, and reduced gold output.
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.
To highlight the key potential underlying causes.
By correlating (and / or using other statistical methods) the hypothesised causes to the problem to ensure proven causality, when we solutionised we were confident of success.
We adopted the solution and continued adding data to the Process Behaviour Chart established in Step 1., to ensure changes were effective, and sustained.
Tyre damage was reduced by 50%, a $4m+ benefit per annum!
