value
Value
  • Value added activities
    • Anything the customer is willing to pay for
    • Anything that changes the form fit or function of the sample
  • Non-value added activities
    • Defects
    • Excess processing
analysis
Analysis
  • 239 hours spent on non-value added activities!
  • Only 13 hours were value added!
analysis1
Analysis
  • 36 opportunities for improvement
  • Prioritized based on implementation time, customer centeredness, improved turnaround time, error reduction, efficiency, safety, work balance and cost.
improvements
Improvements
  • Reducing analytical batch sizes and increasing the frequency of analyses
  • Middleware to interface instrumentation with the LIMS
  • Staggering shifts
  • Cross training analysts for reporting
  • Automation of manual analyses
conclusion
Conclusion
  • Hard work (who wants to be non-value added?)
  • Diminishing returns sometimes “better beats best”
  • Strong management support
  • Willingness to change
