Whether your CMMS or EAM is a world-class software installation or a stack of file cards in a shoebox, the time to capture the takeaway from maintenance work comes at the end of each job. When it’s time to close a maintenance work order, the right people are there with the right information fresh in their minds. The challenge for any system owner is to make it automatic for them to share and capture the information.
The promises that prompt us to make CMMS or EAM installations are wonderful: We’ll have full knowledge of maintenance cost and availability of our equipment. We’ll know which spares to stock to keep equipment healthy. We’ll have clear instructions and up-to-date labor estimates for all routine repairs and condition monitoring activities. All of these promises and more are within the reach of a CMMS, but the systems, as installed, are only media. The content must be added at installation and, more important, constantly updated for the systems to be useful.
After the basic data tables are loaded in a CMMS, the three most important update opportunities occur at work order entry, scheduling, and closure. The first two, order entry and scheduling, usually happen on the CMMS. The order must be started with a reasonable amount of detail, or PdM and repair work will not happen. Similarly, parts and services must be ordered or repairs cannot be done. If the systems are used properly to automate the order entry and scheduling, they will make information capture automatic, as well. Work orders and material orders will flow from the system and the information on them will be retained by the system and associated with the appropriate work orders. If the work orders are written properly, they will also associate the work and material costs with the asset number in the system.
The greatest of the three data capture opportunities, job closure, does not share this advantage. No information is needed to close the job and turn the equipment back over to production. The team can simply notify the foreman and leave the scene. Moreover, job completion and closure usually occur when everyone is anxious to pack up and leave the job site. This is the moment when all the information learned from the repair is fresh in the team’s minds, and the team is all together at the job site. Even the contractors are often present. But unless management insists on data capture at the moment of closure, the equipment will simply be returned to production and the maintenance crew will disperse.

The nomenclature varies a little, but job completion is defined in most systems as the point where the physical work is done and the equipment can return to production. Job closure is the point where the work order is declared complete and closed in the system. Before job closure occurs, a great deal of new information should be captured. At a minimum it includes:
- actual in-house labor hours spent, by job classification
- actual contractor labor hours spent, by job classification and vendor
- actual parts used
- specific equipment failure mode
- specific repair strategy
- condition of equipment when returned to service
- total time elapsed while equipment was unavailable
- time when equipment was returned to available status
- additional work or monitoring required in the future
- other work orders initiated as a result of the service
- changes needed to work instructions and time estimates for repairs.
With this information the organization can ascribe costs to the equipment correctly, making lifecycle costing and data-driven replacement decisions possible. The data also provide needed information on equipment condition and future repair needs. Most important of all, maintenance job instructions and standards can be updated with actual information that can improve future planning and scheduling of PdM and repair work.
With adequate information capture at work order completion and closure, the organization can begin to achieve the benefits of a fully functioning CMMS or EAM system. Unfortunately, the work of recording job closure data happens in the classic situation that trips up most systems. The work must be done today by the people at the job site for the future benefit of other people. It is additional work without immediate benefit to the people who must do the work. It would be nice if we could count on the nobility of spirit and the altruism of workers to deliver these future benefits to their coworkers. However, experience suggests that some other forms of encouragement might be needed to improve our chances of success.
