Predictive and Preventive Maintenance Statistics

Maintenance planning requires solid data, much of which you’ll obtain by collecting information on your own operations. It also helps to know what’s happening in the industry as a whole—that way, your own metrics are compared within a larger context. This ultimately helps you gauge where your own maintenance management processes are. You’ll get an idea of where you’re doing well and where you might need to make improvements in terms of maintenance management.

In addition, these statistics show just how important modern technologies are in terms of improving operational reliability, no matter how well you’re doing in comparison with the industry overall.

  • Maintenance technicians are most widely employed by the plastics manufacturing industry at 3,830 employees. The next runner up was motor vehicle parts manufacturing with 2,750 workers (Bureau of Labor Statistics).
  • First line supervisors of maintenance workers tend to earn more, averaging at $68,120 per year (Bureau of Labor Statistics).

Time management

  • Out of an average working day, only 24.5% of the average maintenance worker’s time is spent performing productive tasks (Plant Services, 2003).
  • Doing the math for an average maintenance technician based on average salary, the total time spent on unproductive tasks comes out to about $38,082 in labor costs per personnel per year.
  • An estimated 20.9% of wasted time results from travelling to different areas in the facility, with an additional 19.8% resulting from waiting for instructions (Plant Services, 2003).
  • Poor maintenance strategies can reduce a company’s production capacity by as much as 20% (Wollenhaupt, 2017).

How to use the data

By comparing your own metrics to the data listed above, you can get a clearer idea of where your facility stands in terms of maintenance effectiveness.

For example, if your maintenance costs seem a little high compared to those listed above, there may be something amiss in your processes. You may be deferring maintenance too often, thereby allowing assets to age too much without regular upkeep, or you may have some inefficiency in personnel management.

It’s also important to note that a general trend may not necessarily apply to your situation. For instance, running equipment to the point of failure without regular maintenance can get expensive from a cost-effectiveness standpoint. However, if you already have aged assets at your site, you’ll need to compare the cost of replacement to that of maintenance. In some cases, an equipment upgrade could make more sense than performing additional repair work.

Ultimately, industrial data can help you make important decisions regarding your maintenance strategies, especially when combined with a thorough understanding of your own metrics.
