MS.04 Identify Future Strategy Changes

Context

The Operating Master Schedule lays out the sequence and timing of the Production and Service Work that must be executed in order to deliver the process Performance targets. The starting point for forecasting the Operating Master Schedule must be the; • current Production work and operating parameters defined in setting the Production strategy, • current Service work defined in setting the Service Strategy. The expectations, design and operation of processes are not however guaranteed to be unchanging over time. These parameters may be changing due to customer expectations and demands, modification or adaptation of the process, changes in the resources available to the process. Since forecasts are by nature developed well ahead of the events that they are predicting, they must have the current strategies as there starting point but must reflect the expected timing and effects of future changes in strategy that have been identified for the process. Such changes will likely result in the commencement and/or termination of schedule Activities, or changes to the nature of some Activities. Where such changes may have a significant effect on the frequency, timing, impact or resourcing of any Activity within the Operating Master Schedule, these changes must be reflected in the Schedule.

Purpose

To specify the Scheduling Model elements/characteristics that must be set up for future Production and Service Strategy changes.

Quantity

• One Operating Master Schedule Activity for each new Production or Service Work activity that will fall within the top 20% estimated impact on performance and costs. • One Operating Master Schedule Activity for each modified individual or group of Production or Service Work packages.

Quality

Forecast changes to Production and Service Work shall be reflected in the Operating Master Schedule by retaining the existing Activity and creating a new Activity for the changes resulting from the Strategy changes. A scheduling termination date shall be specified for each Operating Master Schedule Activity that will be superseded as the result of a change in Production or Service Strategy.
