This chapter looks at some of the items connected to the “How Much Work?” question as related to our total maintenance requirements and our current backlog. Trying to manage maintenance without managing the backlog can be a losing situation. A certain level of backlog is needed in order to plan and schedule work. Backlog gives us a picture of resources and whether we are capable of accomplishing work with in-house staff, overtime, staff additions, or outsourcing to contract maintenance providers. Backlog in its simplest terms is work that has not yet been completed.
