For complex jobs you need a job plan that details Safety LOTO/PPE, task and sequence, trades/crafts required, estimated Costs, materials/parts, housekeeping and disposal issues.
Job Plans help you standardize your maintenance and calibration activities. Write them once, reuse them many times.
Job Plans exist in the CMMS library, are not attached to any work orders, you can copy, modify, reuse parts for similar assets.
Use Technician feedback and feedback form to continuously learn and improve your job plans.
