Biopharmaceutical manufacturing
From cluttered to controlled: standardising CMMS
A biopharma facility needed to bring its SAP PM database back under control after an internal audit identified duplicated, obsolete and unclear preventive-maintenance tasks.
Context
Maintenance work orders were being completed without dependable task content.
The SAP PM database contained duplicated tasks, incorrect equipment links, obsolete records and missing long-text instructions.
The issues had been raised during an internal audit. The site needed a structured clean-up that improved operational clarity while meeting compliance expectations and reflecting how technicians actually worked.
Risk
Audit exposure
Critical gaps in maintenance planning needed immediate action.
System
SAP PM database
Preventive maintenance content needed to be reviewed against the correct equipment and functional locations.
Users
Practical execution
Maintenance Engineers, Reliability Engineers and Technicians needed to trust the revised tasks.
Approach
Start with criticality, standardise what works and control the change.
RTL combined data review with close collaboration across reliability, maintenance and spare-parts teams.
Use the site's criticality assessment to start with high-priority systems.
Group equipment by type and identify duplicate, inconsistent, obsolete and missing PM content.
Build PM groups from the most accurate instructions already in use and fill gaps where content was unclear.
Work with the relevant Maintenance Engineer, Reliability Engineer and Technicians to test practical application and safe execution.
Submit updates through formal SAP and Quality change control before uploading to the live system.
Sustainability
Control was designed into the system, not left in a spreadsheet.
A feedback mechanism gave technicians and planners a route to raise issues with PM content for ongoing review.
The pilot involved cross-functional input from Reliability, Maintenance and Spare Parts teams. The revised content was designed to remain useful after the initial clean-up and to support continued improvement across additional business units.
Correct links
Tasks were aligned with the correct equipment and functional location.
Clear instructions
Blank and outdated long-text fields were updated with accurate, easy-to-follow guidance.
Ongoing feedback
Users could raise issues for review instead of allowing content quality to decay again.
Result
A cleaner CMMS reduced risk and restored confidence in the maintenance system.
The pilot reduced system complexity, improved task clarity and created a more practical, safer and sustainable structure for routine maintenance.
The source case study describes reduced operational and compliance risk, time savings across planning and execution, and restored confidence among daily users.
Next step
Are outdated PM tasks increasing audit or operational risk?
RTL can help prioritise the clean-up, standardise content with the people who use it and establish control for what happens next.
