Six Sigma and Beyond: Design for Six Sigma, Volume VI

BOOKSHELF DATA

Activities associated with the bookshelf data stage include:

  1. Identify good design practices.

  2. Collect machinery things gone right/things gone wrong (TGR/TGW).

  3. Document successful machinery R&M features.

  4. Collect similar machinery history of mean time between failures (MTBF).

  5. Collect similar standardized component history of mean time between failures (MTBF).

  6. Collect similar machinery history of mean time to repair (MTTR).

  7. Collect similar machinery history of overall equipment effectiveness (OEE).

  8. Collect similar machinery history of reliability growth.

  9. Collect similar machinery history of root cause analyses.

At this point it is important to ask and answer this question: Have we collected all of the relevant historical data from similar operations or designs and documented them for use during the process selection and design stages?

MANUFACTURING PROCESS SELECTION

Activities associated with the manufacturing process selection stage include:

  1. Identify general life cycle costs to drive the manufacturing process selection.

  2. Establish OEE targets including availability, quality, and performance efficiency numbers that drive the manufacturing process selection.

  3. Establish broad R&M target ranges that drive the manufacturing process selection.

  4. Establish manufacturing assumptions based on cycle plan, including volumes and dollar targets.

  5. Identify simultaneous engineering (SE) partners for project.

  6. Select manufacturing process based on demonstrated performance and expected ability to meet established targets.

  7. Search for other surplus equipment to be considered for reuse.

  8. If surplus machinery has not been identified for reuse, identify a supplier, based on manufacturing process selection (evaluate R&M capability).

  9. Generate detailed life cycle costing analysis on selected manufacturing process.

At this point it is important to ask and answer these questions: Have broad, high level R&M targets been set to drive detailed process trade-off decisions? Is the life cycle cost analysis complete for the selected manufacturing process? Do the projections support the budget per the affordable business structure?

R&M AND PREVENTIVE MAINTENANCE (PM) NEEDS ANALYSIS

Activities associated with the R&M and PM needs analysis stage include:

  1. Establish a clear definition of failure by using all known operating conditions and unique circumstances surrounding the process.

  2. Establish R&M requirements for the unique operating conditions surrounding the chosen manufacturing process.

  3. Establish/issue R&M engineering requirements for the project to the designers of the machinery.

  4. Identify PM requirements for maintainability.

At this point it is important to ask and answer this question: Have specific R&M targets been set to support the unique operating conditions and PM program objectives?
