Key Performance Indicators (KPI), like mile markers on a highway, provide an indication of performance and, all being well, a measure that progress is being made.

When applied to the Highway Maintenance sector KPI’s are a benefit for the Engineer and the Politian alike to know that policy and practices are effective. This paper explores how KPI’s can be used effectively in highway maintenance.
