Continually Increasing Quality Means Continually Increasing Value

  • ESC reduced DPMO (Defects per Million Opportunities) from 2400 to under 200 within the first nine months of implementing the SEA Lean Enterprise System.
  • Direct Benefits: lower cost of doing business, controlled processes, predictable results.
  • Indirect Benefits: A reduction in rework (and the thermal shock caused by solder iron touch-up) and therefore the reduction of field failures.
