What is preventive maintenance compliance (PMC)?<\/h2>\n

Calculating <\/span>PMC<\/span> helps <\/span>maintenance teams<\/span> identify the percentage of <\/span>preventive maintenance tasks<\/span> they\u2019ve completed compared to their total <\/span>total number<\/span> of scheduled maintenance tasks over a <\/span>given period<\/span> of time. It is a useful <\/span>metric<\/span> for identifying gaps in a <\/span>preventative maintenance strategy<\/span>.<\/span><\/p>\n

Preventive maintenance<\/span><\/a> work<\/span> is a crucial aspect of any industrial facility\u2019s maintenance plan. Compared to <\/span>reactive maintenance<\/span>, when a <\/span>maintenance team<\/span> tackles problems as they occur, <\/span>preventive maintenance strategies<\/span> are structured to help prevent problems from occurring in the first place.\u00a0<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row kd_background_image_position=”vc_row-bg-position-top” css=”.vc_custom_1687442797424{margin-top: 40px !important;}” el_class=”limble-page-blog-width”][vc_column][vc_column_text]<\/p>\n

How do manufacturers use PM compliance?<\/h2>\n

Preventive maintenance<\/span> is only a helpful strategy when teams comply with it and complete tasks according to their <\/span>maintenance schedule<\/span>. If teams consistently miss <\/span>PM work<\/span>, companies face the risk of <\/span>equipment failures<\/span> and <\/span>breakdowns<\/span>.\u00a0<\/span><\/p>\n

Preventive maintenance compliance scores<\/span> tell manufacturing organizations whether they are keeping up with their <\/span>preventive maintenance activities<\/span>. This way, they can determine if they need to make improvements to their <\/span>PM program<\/span><\/a>.\u00a0<\/span><\/p>\n

PMC<\/span> is also helpful in preparing for <\/span>audits<\/span> and identifying long-term solutions to recurring issues. It increases the accountability of maintenance technicians when they work to improve the <\/span>PMC<\/span> score and helps companies improve their <\/span>work order<\/span> processes.\u00a0<\/span><\/p>\n

Calculating <\/span>PM compliance scores<\/span><\/h3>\n

Calculating <\/span>PM compliance<\/span> is a relatively simple formula. A company must take their number of completed <\/span>preventative maintenance tasks<\/span>, divide that by their total scheduled <\/span>PM tasks<\/span> during this <\/span>time frame<\/span>, and multiply that number by 100 to get their <\/span>PM compliance<\/span> percentage.\u00a0<\/span><\/p>\n

Preventive maintenance compliance formula<\/span><\/h3>\n

Here\u2019s a closer look at the numbers that go into calculating <\/span>PM compliance<\/span>.\u00a0<\/span><\/p>\n

(# of <\/b>completed PM<\/b> activities \/ # of scheduled PM activities) x 100 = <\/b>PMC<\/b> percentage<\/b><\/p>\n

Let\u2019s say a manufacturing plant has 200 scheduled PM activities over a 3-month period. 50 went incomplete, leaving just 150 tasks completed within that period. The <\/span>PMC<\/span> score would be 75%.\u00a0<\/span><\/p>\n

(150 \/ 200) x 100 = 75%<\/b><\/p>\n

A general rule of thumb to minimize <\/span>downtime<\/span> and keep operations running smoothly is to aim for at least a 90% <\/span>PMC<\/span> score.\u00a0<\/span><\/p>\n

The 10% Rule<\/span><\/h3>\n

Even tasks completed within the <\/span>time period<\/span> of the <\/span>PMC<\/span> calculation can cause complications if <\/span>maintenance teams<\/span> complete them after the scheduled <\/span>due date<\/span>. Consistently <\/span>late PM tasks<\/span> are likely a sign of issues in your <\/span>maintenance processes<\/span>.\u00a0<\/span><\/p>\n

To gain a more accurate <\/span>PMC<\/span> score, it\u2019s helpful to understand and use the 10% rule.\u00a0<\/span><\/p>\n

The 10% rule is simple: <\/span>only tasks completed within a 10% window of their scheduled <\/b>due date<\/b> count as a <\/b>completed PM task<\/b>.\u00a0<\/b><\/p>\n

For example, if a part needs to be replaced every 90 days, it would only be considered complete (for the sake of the calculation) if it was complete within 9 days of (on either side) its scheduled <\/span>due date<\/span>.\u00a0 <\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row kd_background_image_position=”vc_row-bg-position-top” css=”.vc_custom_1687440273251{margin-top: 40px !important;}” el_class=”limble-page-blog-width”][vc_column][vc_column_text]<\/p>\n

Why is preventive maintenance compliance important?<\/h2>\n

Preventive maintenance compliance<\/span> is a crucial measurement for <\/span>maintenance teams<\/span> to understand their current capabilities. If you consistently have a low <\/span>PMC<\/span> score, it\u2019s probably time to change your strategy. This might entail increasing personnel, outsourcing, or finding another way to keep up with <\/span>maintenance schedules<\/span>.\u00a0<\/span><\/p>\n

If a company finds that they are consistently getting a low <\/span>PMC<\/span> score, then they won\u2019t reap the full benefits of their <\/span>preventive maintenance strategy<\/span>.\u00a0<\/span><\/p>\n

Let\u2019s look at some of those benefits:<\/span><\/b><\/p>\n
