Maintaining products and equipments is a tough and dangerous job. Knowing and following the basic lessons is very important. When I asked what the product of the maintenance department is? The standard answer I got was that the maintenance department\\\'s product is to repair broken equipment. If capacity is the objective, then the management should be focused on optimizing capacity (the most capacity for the least resources). Since the capacity is so valuable the maintenance resources is a small input into the calculation. Maintenance makes capacity. There is way more money to be made annually for the company in increasing capacity then there is in a decade of maintenance budget cuts.
