P.Maintenance schedule

Schedule for thePreventive maintenance of equipments has been prepared in the month of December for succeeding year…

Here my question is, if any equipment has decommissioned or any equipment is installed, then how to proceed the schedule…Is it required to prepare new one or something else.

Thanks in advance…

Any major change in the existing equipment or instrument (commissioning or de-commissioning) must be handled through the Change control (CC) system. When the CC will be reviewed and approved by QA the change should be executed. At the same time existing SOPs, Preventive Maintenance schedules of the old equipment should be made obsolete and new / revised documents of new equipment or instrument should be prepared (such as IQ, OQ, PQ, Validation, Calibration, Preventive maintenance etc).

Great question. If an equipment is decommissioned or a new one is added after you’ve prepared the annual preventive maintenance (PM) schedule, you don’t need to redo the entire schedule.

Instead, just update the existing schedule by:

  • Removing the decommissioned equipment’s PM tasks
  • Adding the new equipment’s PM tasks with appropriate frequencies

Using a CMMS like Fogwing makes this easy — you can quickly adjust schedules anytime without starting over.

Handling Addition of New Equipment to PM Schedule

Option 1: Prepare an Addendum Schedule

Create a separate addendum document that covers only the new equipment from the effective month.

Advantages: Easier to prepare quickly, keeps original schedule intact.

Disadvantages: Risk of oversight or omission during execution.

Best practice: proper training and clear referencing between the original PM schedule and addendum.

Option 2: Prepare a Revised Complete Schedule

Incorporate new equipment together with existing equipment in a single updated schedule starting from the effective month.

The old schedule with empty columns left unexecuted will be strike off by referencing the appropriate change control number and close it, handover to QA

Advantages: Single unified schedule reduces risk of omission, clear and consolidated.

Disadvantages: Having multiple versions present during audits may cause some confusion, which must be preemptively explained.

Handling Decommissioned Equipment in PM Schedule

Option 1: Strike Off Decommissioned Equipment Column

Continue using the original schedule but cross out the decommissioned equipment column by referencing the change control.

Proceed with maintenance on remaining equipment as planned.

Advantages: Minimal disruption, easy to implement.

Disadvantages: The schedule contains “Blank” columns, which may be confusing during reviews if not properly documented.

Option 2: Prepare a Revised Schedule Without Decommissioned Equipment

Prepare an updated schedule excluding the decommissioned equipment from the effective month.

The old schedule with empty columns left unexecuted will be strike off by referencing the appropriate change control number and close it, handover to QA.

Disadvantages: Similar to addition scenario, presence of multiple versions may need explanation during audits.
