The bottom line is that all maintenance tasks, scheduling, parts procurement, and labor are documented. This may sound like a lot of documentation, but when spread among dozens of people it is much easier than the supervisor or planner trying to keep up with all of it. With each piece of documentation, equipment history is preserved. Leave the data massaging to the bean counters. Get the data that you need to improve the process, institute a reliable fix, and move on to other things that are more deserving of your attention.
Accountability is simply the process of closing the loop.
If a reporting system is open ended, it is doomed to failure. There has to be a vehicle to assure that tasks have been completed, parts are on order, equipment is scheduled, and people are paid. The CMMS is that vehicle. The CMMS is a very effective tool for closing that loop. It allows all maintenance personnel access to the information that is needed to accomplish their missions effectively.
