The scope of this project was Strategic KPI Benchmarking, identification and prioritisation of poorly performing sites.

A tool has been built utilising business intelligence visualisation software and fed with available client cost and asset performance data. The success of the tool was dependant on the quality and quantity of the data used within the tool and therefore we ensured close collaboration with client personnel in Asset Management, Finance, Operations and Scientific.

The KPI summary output highlights the works that most deviate from the norm from an Opex and Capex perspective. These can be normalised against areas such as size of works, the permit requirements and the types of process adopted.

A summary dashboard reports on the most expensive or highest performance risk sites and focusses asset planners and budget holders on these sites. The least expensive and lowest performance risk sites can also be reviewed as examples of good practice that can be adopted at other sites.

We also included a prioritised schedule of improvements on a return on investment basis which our client is now considering developing into a multi-site optimisation programme.
