The craftsmen dedicated to the units felt needed and like they were making a more direct contribution than before as part of a pool. They learned their unit's equipment intimately, and became more proficient and committed to unit performance. In most cases the dedicated crews are working on schedule breakers because of the ease of deploying them. If there is a plantwide priority system, it has no application to these crews. Rather, work is done to the same urgency as the production schedule.
Planners dedicated to units do very little routine planning.
Instead they are expediters or on-call supervisors, and when they do plan, it is for outages. Maintenance craft skills are deteriorating. No one in the organization is assuring the continuing development of craft skills. The computerized maintenance management system's data quality is highly compromised. Some units may use the CMMS, and others don't.
