2.3 Shortage management (the “chase” process)

A material shortage is an operational challenge that directly impacts factory utilization and revenue recognition. Shortage management requires a structured, proactive “War Room” approach: daily intervention and cross-functional coordination until the Clear-to-Build (CTB) signal is restored and verified.

The shortage protocol

A shortage exists when the Committed Supply is less than the Firm Demand within the active production window. It must be managed formally as a defined operational issue, rather than informally via email.

The daily rhythm (the stand-up)

The Shortage Review should ideally occur daily at a fixed time. Focus the meeting on active resolution rather than passive status reporting.

• Duration: Keep it concise (e.g. 15-30 minutes maximum).
• Focus: Blocker removal and exception management.
• Actionable Data: For every critical shortage line, the owner should provide:
  1. The Constraint: Specific Part Number and Quantity.
  2. The Impact: The projected Line Stop Date.
  3. The Next Action: The specific tactical step being taken to resolve it.
  4. The Deadline: When a definitive update is expected.

Mitigation options (the execution playbook)

When the standard supply channel encounters delays, Procurement must explore parallel recovery paths simultaneously.

When the Standard Channel is Delayed:

1. Spot Buy / Independent Sourcing:
   • Engage vetted independent distributors. Ensure strict adherence to counterfeit testing protocols (e.g. AS5553/AS6081) when buying on the open market.
   • The Financial Decision: Evaluate if the premium cost of a spot buy is offset by preventing a more expensive factory line-down event.
2. Alternate Sourcing (Engineering Pivot):
   • The Action: Ask Engineering to review for a potential “Drop-in Replacement.”
   • The Logic: Check for generic commercial equivalents (e.g. standard logic gates or passives) where components from different manufacturers are functionally identical.
3. Logistics Acceleration:
   • The Action: Upgrade freight to expedited methods (e.g. Next Flight Out or Air Freight).
   • The Evaluation: Determine financial responsibility based on whether the supplier missed their committment or if internal demand spiked inside standard lead time.
4. Production Re-sequencing:
   • The Action: Evaluate splitting the build lot to produce a partial quantity with available stock, allowing the SMT line to run while awaiting the balance.
   • The Caution: This increases setup costs and tracing complexity, so it is typically a last resort.

The escalation ladder

Escalation is the structured application of corporate leverage. Utilize organizational tiers to resolve road-blocks efficiently.

Escalation Tier	Trigger Point	Typical Owner	Tactical Action
Level 1	Shortage Initially Identified	Buyer	Validate PO status, request expedite, check franchised disty stock.
Level 2	Vendor unresponsive > 24 hrs	Sr. Buyer	Engage Supplier Sales Manager to request allocation release.
Level 3	Impact arriving < 1 Week	SCM Director	Escalate to Vendor Leadership; potentially authorize broker premium.
Level 4	Line Down Imminent	Executive	Executive-to-Executive communication; deploy critical resources.

The shortage tracker (the kanban board)

Manage the “Chase” through a highly visible, centralized dashboard (e.g. a Kanban board or shared tracker tool).

Criticality	Impact Date	MPN	Qty Short	Root Cause	Mitigation Plan	Owner	Next Update
CRITICAL	Oct 24	MCU-F405	500	Vendor Fab Delay	1. Evaluating spot buy. 2. Eng reviewing ‘RGT6’ alt.	J. Doe	14:00
High	Oct 28	Conn-USB	2k	Demand Spike	Air Freight booked (Awaiting tracking #).	S. Smith	Oct 26
Med	Nov 05	Res-10k	10k	Yield Issue	Pulling in quantity from the subsequent PO line.	J. Doe	Oct 30

Pro-Tip: Monitor a “Watch List” for items that are technically covered but have minimal buffer inventory. A single IQC reject at Receiving can turn these into immediate shortages.

Root cause analysis (closing the loop)

Resolving the immediate crisis is essential, but structurally addressing the underlying flaw prevents recurrence.

A shortage incident should ideally include identifying the root cause and implementing a corrective action within the ERP or planning system.

Examples of Structural Fixes:

• Issue: Consistent Vendor OTD Failure → Fix: Adjust Vendor Scorecard and evaluate increasing the system Safety Stock buffer temporarily.
• Issue: Inaccurate ERP Lead Time → Fix: Update the ERP Lead Time parameter (e.g. from 12 weeks to 20 weeks) to reflect market reality.
• Issue: Unforecasted Demand Spike → Fix: Review the sales forecasting process or formalize buffer inventory agreements with the customer.
• Issue: Significant Incoming Quality Rejects → Fix: Issue a Supplier Corrective Action Request (SCAR).
