MS.05 Are there Irregular Additions or Omissions to the Schedule?

Context

The Production and Service strategies for an process are developed to deliver the required performance targets, and a good Production and Service strategies will identify most of the work that will regularly be required in the Operating Master Schedule. Hence, the process of Setting the Master Operating Schedule has to this point focused on building the schedule around the Production and Service Strategies. One predictable characteristic of real processes, operated in the real world, is that there will be variation, and the Operating Master Schedule is not immune from this. In any forecasting period there is certain to be some work that does not regularly occur, and there is certain to be some work that is normally required that will not be necessary during a particular period.

Any irregular additions or omissions to the Operating Master Schedule need to be identified if the Schedule is to be complete and accurate.

Purpose

To identify any irregular additions or omissions to the Operating Master Schedule.

Quantity

• One list of activities that are to be included as a ‘once off’ in the Operating Master Schedule. • One list of activities that must have one or more occurrences ‘suppressed’ in the Operating Master Schedule.

Quality

A draft Operating Master Schedule, reviewed in detail and in light of the known context for a forecasting period, can provide a prompt to stimulate people to recognise irregular changes required to the schedule. The draft Operating Master Schedule should be issued to the group of personnel who will be required to provide input. The appropriate personnel should record their individual suggestions for irregular changes to the schedule. These should be ‘brainstormed with the group to confirm the list of changes that are required.

A list of the agreed ‘once off’ changes to the schedule shall be compiled.

Time

At each forecasting cycle.
