Quality

The deliverables shall meet the following requirements; • The flowsheet for the operating process shall define each transform, transfer and store work step comprising the Production process. In determining the level of detail in the flowsheet, proceed to the level that ensures each person operating or monitoring the process has a clear and unambiguous understanding of all of the work steps that are material to the delivery on the process outcomes, plus their sequencing and dependencies. • The Production Strategy critical issues shall be those value driver parameters that will have the dominant impact on closing the gap between the current and required Capability Histogram(s) of the performance measures of the process. • The feasible Production strategies for each Productive Unit shall include the following; o Design • The feasible and selected Production strategies shall be substantiated by statistical modelling indicating the potential range of performance outcomes for a combination of Production strategies for each Productive Unit. The range of potential outcomes shall be in the form of capability histograms for the output of the Productive Unit, and for each of the independent characteristics that contribute to output (time, rate, quality, efficiency, etc.) that are used as an input to the model. • Operating specifications shall be provided for every step in the process flowsheet, and for the actions necessary to deliver the step. In determining the level detail in the specifications proceed to the level that ensures will be a clear and unambiguous understanding of all operating parameters that are material to the safe and successful completion of the production step/actions, and the process as a whole. Note – machine executed steps will typically require a much more detailed flow-sheet and specification than those executed by people, because people typically have knowledge, experience, skill judgement that they will use in conjunction with the flow sheet and specification. • The Production work steps/actions executed and controlled by machines shall be those where both the physical effort and its control is undertaken by machinery (i.e. fully automated). • The specifications for control systems shall include the inputs, outputs, process control logic and operating specification limits. • The Production work steps/actions executed or controlled by people are those where people either directly provide physical effort to complete the step (e.g. pushing a wheelbarrow), or where they manually control equipment that provides the physical effort to execute the work step (e.g. driving a truck). • The specifications for a Production action to be completed by a person shall include work outcomes and specifications, trigger parameter for o Operating Time, o Operating Rate, o Feed Quality, o Output Quality.
