3.5.1 Schedule Requirements

The schedule should be a management tool (specifically including first line supervision)

to control and direct maintenance activities. It should be used by management to

determine the critical path and explore alternatives when needed. The schedule should

be a concise method for tracking completion of maintenance tasks, particularly critical

path activities. The following are some of the attributes that should be included in the

schedule:

The schedule should be useful. The individuals expected to follow the schedule

need to understand that it should make their tasks and the tasks of others easier.

They also should understand the importance of their tasks in relation to the

schedule as a whole.

The schedule report format should be appropriate for the user. The level of detail

needed by the plant manager is different from the level of detail needed by a craft

supervisor.

The schedule should be proactive in that it should predict and lead activities and

not only be an historical document.

The schedule should be credible. It should be based on the best information

available and reviewed and accepted by those actually responsible for doing the

work.

The schedule should be up to date. The schedule should be updated to reflect

changing situations to maintain credibility. An out-of-date schedule often may be

worse than no schedule.

The schedule should be flexible, within the overall goals of the plant, in order to

produce optimum results in dealing with unanticipated events.

There should be one overall schedule. The overall schedule should be developed

such that a hierarchy of schedules of varying detail may be obtained from a

common data base. It has generally proven difficult to keep two or more

schedules consistent, even when significantly different in level of detail

shown.
