Looks like there’s a reliability-centered maintenance process to fit any company, regardless of size.

RCM For All

Heretofore, reliability-centered maintenance (RCM) may have been thought of as a strategy best left to large, non-lean organizations. That may have been a perfectly logical assumption. Small- to medium-sized enterprises (SMEs) and lean operations simply seem to have less money to invest in and/or fewer resources to cope with the many activities required for RCM success. Now, however, out of joint academic/industry collaboration in Spain, comes information that may help begin to put these types of popular misconceptions to rest. The RCM methodology described in this overview of the Spanish research has been adapted to meet the specific needs of today’s smaller, leaner organizations. And it is not just a theory, either. The practicality of this approach is being confirmed through actual testing in three small- to medium-sized and/or lean companies.

Although reliability-centered maintenance (RCM) has gained increased acceptance in industrial companies around the globe over the past few decades, it often has proven to be a difficult fit for small- to medium-sized enterprises (SMEs) and those in the advanced stages of lean production. For SMEs, the problem appears to be the substantial investment that is required for RCM to achieve the expected outcome. The challenge for lean companies is the fact that they typically manage fewer resources than are needed to successfully implement RCM.

Thanks to a recent academic/industry collaboration, however, a process for overcoming these roadblocks to RCM implementation has been put forward. Developed at Spain’s Mondragon University, this approach has been successfully tested in three small- to medium-sized companies with advanced lean operations. These sites include:

  • A medium-sized industrial plant of the Mondragón Corporación Cooperativa (MCC) corporation (a supplier to automotive and home-appliance OEMs and Spain’s third-largest company);
  • Inquitex S.A. (Inquitex), a maker of various products
using polyamide, polyester and PET;
  • Goizper S. Coop. (Goizper), a cooperative serving industrial and agricultural markets, and maker of a popular hand-held sprayer for houseplants.
  • The RCM process
    The RCM process is designed to enhance assets’ availability and safety by recommending design improvements or maintenance and operation tasks. It entails asking the following seven questions about the system under review:

    1. What are the functions and associated performance standards of the asset in its present operating context?
    2. In what ways does it fail to fulfill its functions?
    3. What causes each functional failure?
    4. What happens when each failure occurs?
    5. In what way does each failure matter?
    6. What can...(Read whole article)
