• EEM is not just an Engineering activity but a collective effort with plant technicians,  operators,  crafts, supervisors, etc.
  • EEM learnings are best obtained with one to one discussions with shop floor personnel.
  • EEM must become part of the Capital Expenditure process with acknowledgment of EEM consideration similar to Safety and Environmental input.
  • The EEM team will address speed to market in all our efforts, knowing the extra upfront time it takes to do EEM right.

Early Equipment Management Goals

  • Design production equipment that is easy to use, easy to maintain, highly reliable, and well-engineered.
  • Reduce the time from equipment development to production and achieve ‘vertical start-up’

Long Start-up Period

  • Lots of teething troubles
  • Time to transfer operation skills
  • Lack of detail
  • Little operational input

Difficult to sustain & improve

  • Machines have worn after the warranty period
  • Insufficient daily maintenance
  • Continuous introduction of new material/product
  • Slow skill “catch-up”

Causes of Poor Start-up: 4M’s

  • Man

4M’s “Machine”


  • no feedback of improvements
  • insufficient consideration of ease of operation, maintenance
  • insufficient standardization
  • unreliable parts, special parts


  • misalignment

4M’s “Other”


  • insufficient for design modification


  • insufficient forecasts for future uncertainties

Early Equipment Management Goals

MP Information & MP Design

Collect (MP) information about issues with previous equipment designs and use this data to improve the (MP) design of new equipment

  • MP function design
    • ease of operation, maintenance, monitoring, and safety
  • Loss-free design
  • Effective feedback of operational knowledge
    • communication between equipment designer and operators/maintenance staff

Good example?

MP Info: Improvement Records Classification


  • Loss
    • Breakdown / minor stoppage / set-up & adjustment / speed / defect & rework
  • MP function
    • Safety / operability / reliability / maintainability – autonomous maintenance / audit/ economy / quality / friendliness to environment, people
  • Machine / Products
    • Supplier/specification
    • Products/property etc.
  • Information level
    • Horizontal replication / standardization / training / permanent countermeasure

MP Info: Improvement Records Loss / Cost Calculation


  • Losses (less than once / year)
    • Production stop (hr / min)
    • Rework / scrap (ton / unit)
    • Defects / complaints (ton / unit / no. of complaints)
  • Other Losses
    • Losses x frequency (times/year)
  • Reduced speed
    • (Specified – reduced speed) x duration
