Quality

An operating Master Schedule Activity may be defined by; • a Production or Service work package that individually has a process output or cost impact that is in the top 20% of a Pareto analysis of Work Packages over a period, or • a Production or Service work package that is executed many times over a period and the sum of the repeated process output or cost impacts is in the top 20% of a Pareto analysis of Work Packages over the period, or • a random event that has a high probability of occurring within a time period, and that individually has a process output or cost impact that is in the top 20% of a Pareto analysis of Work Packages over the period. or • a group of Production or Service work packages that share a common grouping characteristic that is used to summarise the numerous Work Packages that have a low cumulative impact over a time period. High impact activities shall be identified by Pareto analysis of; • The cumulative process output contribution over a time period - based on the most likely value estimate of a Production work package. • The cumulative process output losses over a time period - based on the most likely value estimate of a Service work package or random disruptive event. • The cumulative costs over a time period - based on the most likely value estimate estimates of a Service work package or random disruptive event. The remaining Production and Service Work, and random disruptive events, shall be filtered and sorted into groupings (preferably based on work type, trigger parameter type, equipment type and strategy type) where the total process performance or cost impacts is of the same order as the lowest ranked of the top 20% of Activities The following data shall be specified for each Activity to be defined within the Operating Master Schedule; • The Standard Job number for the Activity, • the Business Structure element to which the Activity is attached, • the role accountable for the Activity, • a description of the Activity based on the defining characteristics, e.g. for a truck these may include; 250 hour PM services, 10,000 hour engine replacement, hydraulic breakdown repairs etc. • the trigger parameter and value that initiates the Activity, • the trigger parameter tolerance, • constraints on scheduling (e.g. requires plant downtime, or plant operating, etc.), The top 20% of these groupings shall be individually identified as a Activities in the Operating Master Schedule.
