Targeted Operational Improvements • Throughput per hour
o Faster cycle times reduces the hours needed to achieve a certain task or output o Reduced machine hours reduces fuel cost, maintenance cost, repairs, capital depreciation, for the same
amount of output
• Cost per hour o Treating equipment better reduces maintenance costs, regardless of the output / hr o Operating a machine properly can reduce fuel cost and maintenance cost for the same productive output
• Idling, running empty o Like idling for mobile equipment, “black belt time” in crushing and screening
• Reduce wasted material o Sell as much as you can of what you make
• Value of service o Better customer service leads to more business and better pricing
