    Identifying Autonomous Maintenance Tasks

    We recently had the opportunity to participate in the commissioning of a new production line for a major food manufacturer. One of our tasks was to identify the Preventive Maintenance (PM) tasks that would be the starting point for all routine activities at start-up.

    We and the client recognized that creating PM tasks and frequencies was virtually the same process as identifying Autonomous Maintenance (AM) tasks. So we decided to work on the two simultaneously as the most cost effective way to accomplish both. The main difference between PM tasks and AM tasks is subtle, but AM tasks are usually considered to be smaller but more frequent activities to care for the equipment. Many cleaning, adjusting, center-lining,  change-over, and lubricating tasks fall into this category.

    At the time we identified the tasks we did not concern ourselves with who should perform them. After we had a complete duties list for each piece of equipment, the team then reviewed each task and made a decision about whether an operator or a maintenance technician was the right person to perform the job.

    Once this decision was made, tasks to be performed by maintenance techs were entered as PM’s into their CMMS system.

    AM tasks were documented electronically for display on the HMI of the appropriate equipment. These weekly, daily, and shift duties are available to each operator at the touch of a button. The only paperwork involved is a sign-off sheet that each operator completes during his/her shift verifying completion of the appropriate tasks.

    The outcome was a high-quality starting point to begin the continuous process of improving asset care for a new line.
