Overview

Why this workflow matters

Supplier Corrective Action Requests (SCARs) are issued when a supplier delivers non-conforming material or breaches a quality threshold. Without a structured workflow, 8D responses arrive late, D3 containment gets confused with permanent fixes, and SLA deadlines are missed. Proconomy's SCAR module provides a full D0–D8 corrective action workflow with configurable SLA tiers, D0 emergency containment for critical and safety issues, and a supplier portal where suppliers respond directly — creating a complete, auditable corrective action record.

Key Capabilities

  • Full D0–D8 structured workflow
  • Configurable SLA tiers per severity (Minor/Major/Critical/Safety)
  • D0 emergency containment for Critical and Safety issues
  • Supplier portal — suppliers respond to each 8D step directly
  • OEM review and return cycle for D3/D4–D7
  • SCAR rate and closure rate feed into Supplier Scorecard
Process Flow

Step-by-step: how it works

Every step is designed to eliminate manual effort, reduce errors, and give your team real-time visibility at every stage of the process.

🚨01

SCAR Initiation

SQE creates SCAR with non-conformance description, part, PO link, and severity (Minor/Major/Critical/Safety). Critical and Safety issues automatically trigger a D0 step.

30 minutes

What happens

  • SCAR linked to supplier, part number, and purchase order
  • Severity classification: Minor / Major / Critical / Safety
  • Non-conformance description and evidence attached at initiation
  • Critical and Safety issues automatically add a D0 emergency containment step

🛡️02

D0 Emergency Containment (Critical/Safety only)

Supplier must complete D0 containment action within the configured emergency SLA (e.g. 24 hours). SQE reviews and approves or returns.

Configurable (default 24 hours)

What happens

  • D0 step only triggered for Critical and Safety severity SCARs
  • Configurable emergency SLA (default 24 hours)
  • Supplier notified via portal with explicit D0 deadline
  • SQE reviews D0 response and approves or returns with comments

📋03

D1–D3 Problem Definition & Containment

Team identification (D1), 5W2H problem description (D2), and interim containment action with deadline (D3 — configurable SLA, default 48 hours).

D3 SLA: configurable (default 48 hours)

What happens

  • D1: Team members identified by supplier
  • D2: 5W2H structured problem description
  • D3: Interim containment action with deadline — configurable SLA (default 48 hours)
  • Supplier enters each step via the portal; OEM sees progress in real time

🔍04

D4–D5 Root Cause & Permanent Fix

5-Why or fishbone root cause analysis (D4), permanent corrective action selection (D5). Supplier submits via portal.

5–10 business days

What happens

  • D4: Root cause analysis — 5-Why or Ishikawa fishbone diagram
  • D5: Permanent corrective action defined and scheduled
  • Supplier submits D4/D5 evidence via portal
  • OEM SQE can return D4/D5 to supplier if root cause is insufficient

🔧05

D6–D7 Implementation & Prevention

Implementation verification by OEM (D6) and system-level prevention measures (D7). OEM can return to supplier if unsatisfactory.

5–15 business days

What happens

  • D6: Permanent corrective action implemented and verified by SQE
  • D7: Systemic prevention measures documented — control plan updated
  • OEM review and return cycle for each step
  • Supporting evidence uploaded by supplier at each step

D8 Closure

SQE formally closes the SCAR. All 8D steps, evidence, and timeline captured in a permanent record. SCAR closure rate feeds into Supplier Scorecard.

< 1 hour

What happens

  • SQE reviews all completed steps before formal closure
  • D8 closure records SQE identity, timestamp, and closure notes
  • Complete 8D record permanently archived and audit-ready
  • SCAR closure data feeds into Supplier Quality Scorecard automatically

Business Impact

What your organisation gains

These are not theoretical benefits — they are outcomes that procurement teams experience within the first quarter of deploying this workflow on Proconomy.

⏱️
Visible & enforced
SLA Adherence

Every SCAR shows its SLA deadline, current step, and days remaining — SQEs always know which SCARs are at risk before a deadline is missed.

🛡️
Full portal trail
Supplier Accountability

Suppliers respond to every step directly through the portal — creating an immutable record of who responded, what they submitted, and when.

📊
Automatic
Scorecard Data Quality

SCAR rate and closure rate feed into the Supplier Quality Scorecard automatically — no manual reporting, no data gaps.

📋
Complete D0–D8
Audit Trail

Every SCAR contains the full 8D record with evidence, SQE review decisions, return cycles, and closure notes — audit-ready at any time.
