Best Practices When Using Maintenance Acronyms & Abbreviations
Acronyms and abbreviations are great—until they’re misunderstood. Here are some best practices:
1. Define on First Use
Always write out the full term the first time, followed by the abbreviation in parentheses. Example: Preventive Maintenance (PM).
2. Be Consistent
Stick to standard abbreviations across your documentation and communication.
3. Know Your Audience
If you’re communicating with non-technical staff, minimize abbreviations or provide a glossary.
4. Keep a Reference List
Maintain an updated list of common maintenance abbreviations for your team—like this one!
5. Use in CMMS
Leverage your CMMS (like FlowPath) to standardize and automate the use of abbreviations in reports, work orders, and dashboards.
