Work in progress

Other work in order of required completion date.

This sort order is based on the assumption that PM work is the highest priority, which is a normal practice for proactive maintenance organizations. This practice must, of course, be supported by a PM system which contains only well-estimated and well-scoped PM procedures based on sound reliability principles and to which Maintenance and Operating Managers are fully committed.

The completion date for PM work orders should be about 1/4 of the PM work order frequency (e.g., if the PM frequency is monthly, the target completion date should be 7 calendar days after the PM work order is generated).

An alternative to sorting by completion date is to sort by priority, but this may cause work which was given a lower priority in the past but which has an approaching completion date to be overlooked. If priorities and completion dates are not regularly reviewed in the backlog (which they should be) then using priorities may be more appropriate. In the examples shown in this section, the completion date is used for sorting and the priority rating (see Chapter 6) is also shown.

If the maintenance computer system does not have the functionality to produce a useful ready-to-schedule report, copy the backlog information to a spreadsheet (such as Microsoft Excel) and prepare the report from that.

From the sorted ready-to-schedule report, go down the work list to a point where it is estimated that the work shown will require about 1 1/2 times the available trades effort-hours, and ignore all work below this point. If regular backlog reviews have been conducted and the backlog is well managed, no important work will be overlooked. This step is simply to reduce the amount of information that needs to be reviewed to prepare the work schedule.

An example of a ready-to-schedule work priority list is shown on the next page. For each work order there is a line for each trade required and there is a trade "AT" (AnyTrade) which identifies work that can be assigned to any trade where flexible work practices are in effect. A bold horizontal line separates work orders.

The Scheduler should review this report and add appropriate scheduling comments, such as those shown. For example, the comment "can man up" means that, even though the work order may show one person is required, additional people can be effectively assigned. Work that is in progress is also identified.

With input from the Supervisor, the Scheduler has also added some shop housekeeping work to the bottom of this work list.

Note the format of this report, which shows work order numbers and descriptions and equipment numbers and descriptions. Neither description is truncated, which should be a standard for all reports. Estimates include number of people and hours. An index number has been added in the first column. This is used when building the final schedule.
