Production Bottlenecks and Line Stoppages from Slow Non‑Conformance Investigation and MRB Disposition

3 verified sources

Definition

High non‑conformance rates and slow MRB decisions create bottlenecks and excess work‑in‑progress, delaying production schedules and tying up capacity.[6] Case evidence from a leading aerospace manufacturer shows that improving non‑conformance management and flow‑line visibility materially reduced WIP and cycle times, demonstrating prior recurring losses of capacity and throughput.[6]

Key Findings

  • Financial Impact: Implicitly several percentage points of throughput lost; non‑conformance management cited as consuming up to 20% of manufacturing cost, which includes production delays and idle capacity.[1][6]
  • Frequency: Daily
  • Root Cause: Manual, siloed NCR/MRB workflows delay defect detection and disposition, causing parts and assemblies to queue at MRB, starving downstream stations and creating re‑planning and overtime to recover schedules.[1][6] Lack of real‑time data, poor coordination with engineering, and fragmented supplier/non‑conformance data exacerbate cycle‑time and WIP inflation.

Related Business Risks

High Cost of Non‑Conforming Parts and MRB Decisions Consuming Up to 20% of Manufacturing Cost

Up to 20% of total manufacturing cost on affected programs, on an ongoing basis

Lost Billable Recovery and Missed Chargebacks for Non‑Conforming Supplier Parts

Embedded within the up to 20% of manufacturing costs spent on non‑conformance management; a material fraction is potentially recoverable from suppliers/customers but often not fully billed due to poor data and processes.[1][7]

Overtime, Scrap, and Rework Cost Overruns Driven by Inefficient Non‑Conformance and MRB Processes

Up to 20% of manufacturing cost, with documented ~30% reduction in non‑conformance rates (and associated costs) after process improvements, implying substantial recurring prior overruns.[1][6]

Delayed Shipments and Cash Collection from Late MRB Dispositions and Investigations

Not quantified industry‑wide, but embedded in the 20% of manufacturing costs and evidenced by case reports of schedule delays prior to non‑conformance process improvements.[1][6]

Regulatory and Certification Risk from Inadequate Non‑Conformance and MRB Controls

Potentially millions in exposure through findings, required corrective actions, increased oversight costs, and delivery disruptions; not always itemized, but recognized as a major risk area tied to non‑conformance management.[1][7]

Concealment or Misclassification of Non‑Conformances to Avoid MRB Scrutiny

Difficult to quantify, but potential exposure includes hidden rework cost, warranty and field‑failure cost, and regulatory actions when concealed non‑conformances emerge.
