• CHECKLIST

The 8D Closure Velocity

Identify why your 8Ds keep circulating—not closing—and where lead time is really lost

Most organizations don’t have a quality skill problem. They have a flow, looping, and control problem.

Use this checklist to quickly spot where your 8D lead time is silently lost—then fix the biggest lever first:

  • Flow reality check: Do you know how much lead time is real work vs. waiting?
  • Evidence discipline (D2–D3): Is the defect definition, traceability, and evidence storage solid—or leaking time through restarts?
  • RCA control (D4): Do root causes end debates—or create them?
  • Action quality & execution (D5–D6): Are actions measurable, owned, and escalated when overdue?
  • Avoid recurrence & closure (D7–D8): Are you designing verification early—or discovering it at the end?

SupplyOn supports collaborative supplier quality processes—including complaint management and problem solving (8D)—as part of a broader Supplier Quality Management approach aligned to established industry standards:

  • SupplyOn Supplier Quality Management (SQM) includes Complaint / Non-Conformity Management (8D, 9S) within its quality suite.
  • SupplyOn materials highlight measurable improvements like accelerating lead time by 30–40% for quality programs such as APQP and 8D and reducing process costs by 20–60% (context: digitization + process).
