6 | September - October 2014 | www.machinerylubrication.com like to offer a few examples of KPIs that can help you achieve your lubrication program objectives. There are five categories for these key indicators. Oil Analysis KPIs Oil analysis KPIs are meant to verify the quality of the lubrica- tion being applied to equipment by monitoring relevant machine condition indicators. For oil analysis data to be used as a mean- ingful KPI, it is vital that targeted alarms and limits are set appropriately. While loose limits may result in compliance with lube condition and contamination targets, their meaning may diminish to such an extent that they become irrelevant as a KPI. When setting targets, don't consider where the plant is today but rather what targets need to be established to attain the plant's stated reliability goals. Once appropriate targets have been set, logging exception results becomes relatively easy given the availability of commercial oil analysis software packages. New oil deliveries can be treated in much the same way as assets in the field. They should be tested for cleanliness, dryness and fluid properties. You can also use oil analysis data to get an idea of machine health, lubricant health and contamination levels. Work Management KPIs These KPIs are required to evaluate the efficiency and effec- tiveness of routine and ad-hoc lubrication task planning, scheduling, execution and review. While a number of lubrication KPIs can be generated using data from a computerized mainte- nance management system (CMMS) or other generalized predictive and preventive maintenance management tools, some of the most valuable KPIs require data gathered at individual lubrication points. The lubrication task completion KPI gives managers a clear picture of the overall efficiency of lubrication practices at the task level. It is a measure of the total number of completed lubrication tasks divided by the total number of scheduled lubrication tasks over a certain timeframe. A low number may reveal inefficiencies in areas such as lubrication routes, workload balancing, resource allocation or equipment access. The lubrication tasks overdue KPI reflects the total number of lubrication tasks not yet completed versus the total number sched- uled. A high number here reveals similar concerns as a low task completion score. More importantly, this KPI, along with the lubri- cation task completion KPI, tells maintenance organizations how often and to what degree lubrication goals are being met. Storage and Handling KPIs Storage and handling of lubricants and associated consumables in the appropriate types, amounts and condition is an important enabling factor in the provision of quality lubrication. Health, Safety and Environmental KPIs These metrics and targets should reflect the overall site health, safety and environmental system with a particular focus on lubrica- tion. They provide valuable insight to help engineers and technicians LuBRICATIOn TASK COMPLETIOn Frequency Data Source Target Monthly CMMS/LMS >90% Definition # of Lubrication Tasks Completed (LTC) # of Lubrication Tasks Due (LTD) LTC=523 LTD=600 LTComp=87% LuBRICATIOn TASKS OvERDuE Frequency Data Source Target Monthly CMMS <10% Definition # of Lubrication Tasks Past Due (LTPD) # of Lubrication Tasks that were Due (LTD) LTPD=77 LTD=600 LTComp=13% LuBRICAnT STOCK LEvELS Frequency Data Source Target Monthly Inventory Management System Minimum Definition Total lubricant and consumable stocks held.
