Reliability-Centered Maintenance (RCM)

Reliability-Centred Maintenance ensures that an organisation continues to operate as intended and to realise improvements in minimum maintenance levels. RCM recognises that assets have different potential for failure and incorporates this knowledge into recommendations for maintenance plans that have the objectives of improving machine up-time, reliability and return on investment.

An RCM strategy can address dominant causes of asset failure. It defines routine maintenance plans that consist of cost-effective tasks that preserve the most important functions and looks at the planned preventative maintenance history to determine recurring faults etc.

How can a CMMS help build a Reliability-Centred Maintenance strategy?

Effective maintenance software can help users to build a priority matrix for RCM planning. Categories can be set such as:

  1. Emergency – Life, High Risk, Health & Safety
  2. Urgent – The operation of the organisation is at risk
  3. Priority – To fulfil projects or meet deadlines
  4. Routine – Prioritised
  5. Discretionary – Desired but not essential
  6. Deferred – Only when resources allow

These basic steps should help you to move towards RCM:

  1. Identify the assets in your organisation.
  2. Prioritise the assets based on the criteria above.
  3. Assign into groupings.
  4. Set the type and amount of maintenance activities required using information such as technical guidelines, analysis of failings, machine history etc.
  5. Assess the size of your maintenance team.
  6. Identify the maintenance tasks required.
  7. Analyse the impact of failures.
  8. Set the most effective tasks and plan ahead to avoid critical issues.
