How is the critical material list defined and maintained?

The critical material list is defined by the planning team in HublerX — selecting the raw materials where a shortage would stop production on key SKUs. The list is reviewed monthly and updated when new SKUs are launched or production priorities change. Coverage thresholds (amber and red) are configured per material based on supplier lead time and production criticality.

Does the coverage calculation account for quality holds on inbound materials?

Yes. Stock on quality hold is excluded from the coverage calculation — only quality-cleared stock is counted as available. When a held lot is released after inspection, the coverage figure updates automatically. When a lot is placed on hold, the coverage figure drops immediately, which may trigger an alert.

Can the monitoring scope be extended beyond raw materials to packaging components?

Yes. Any material can be added to the critical monitoring list — raw materials, packaging components, consumables, or sub-assemblies. The coverage calculation and alert logic are the same regardless of material type. Operations that have experienced production stoppages from packaging shortages typically monitor their primary packaging components alongside key raw materials.

How does HublerX handle materials with variable daily consumption driven by changing production schedules?

The coverage calculation uses the daily consumption implied by the confirmed work orders on the live production plan — not a fixed average. If the production plan is accelerated, consumption increases and coverage days decrease accordingly. If the plan is deferred, consumption decreases and coverage extends. The figure reflects the actual production commitment, not a historical average.

Critical Raw Material Monitoring

The Problem

A critical material runs out on a Tuesday. The warning was visible on Monday. Nobody was looking.

Every manufacturing operation has a set of raw materials where a shortage immediately stops production on its highest-revenue SKUs. These materials — a key grain, a key fat, a specific packaging component, a key automotive fastener — are known and finite. The information needed to monitor them — current stock, inbound PO status, daily consumption, production plan — exists in the ERP. But it is not assembled and surfaced continuously in a form that allows the planning team to act before a shortage occurs.

Critical material monitoring fails not because of a data problem but because of a process problem: the MRP runs overnight, the exception report is reviewed the next morning, the planner is dealing with the most urgent issue on the list, and the critical material with 3 days of coverage does not get the attention it needs until it has 1 day of coverage and the options have narrowed significantly.

Current Workaround

What most operations do today: Most operations today: the planning team maintains a 'watch list' of critical materials — a spreadsheet updated manually every morning from ERP stock reports. The planner calculates the days of coverage for each material by dividing the current stock by the daily consumption. Inbound PO status is checked separately. The watch list is reviewed in the morning planning meeting. Coverage calculations done manually are prone to error and do not reflect intra-day stock movements. Materials that slip off the watch list because they look fine on Monday can become critical by Wednesday.

The HublerX Approach

Critical material monitoring is a real-time calculation problem — current stock minus daily consumption from confirmed WOs gives days of coverage, and this number changes every time a WO is issued, a GRN is received, or a production order is completed. HublerX maintains this calculation in real time for every critical material — updating coverage the moment any input changes, tracking each inbound PO's expected arrival date against the coverage timeline, and surfacing risk at the right threshold with the right context for the planner to act.

How HublerX Coordinates It

The step-by-step sequence

1
Critical material list defined and monitored
The planning team defines the critical material list in HublerX — the raw materials where a shortage would stop production on key SKUs. Each material is configured with its coverage thresholds — green, amber, and red — and the responsible planner and buyer.
Configuration · reviewed monthly
2
Days-of-coverage calculated in real time
HublerX calculates days-of-coverage for each critical material continuously — current stock (less any quality holds) divided by the daily consumption from confirmed work orders on the live production plan. The calculation updates every time a WO is issued, a GRN is received, or a production order is completed.
Continuous · real time
3
Inbound PO status tracked against coverage
For each critical material, HublerX tracks every open inbound PO — the expected delivery date, the quantity, and the supplier confirmation status. The coverage timeline shows whether the inbound POs will arrive before the current stock runs out. Where a PO is late or unconfirmed, the coverage timeline is marked as at risk.
Continuous · real time
4
Amber alert — planner notified to act
When a critical material's days-of-coverage falls below the amber threshold — typically 7–10 days — HublerX sends an alert to the responsible planner with the current coverage, the production WOs at risk if the material runs out, and the status of open inbound POs. The planner reviews and takes action — expedite the PO, raise a new PR, or activate alternate sourcing.
On amber threshold breach
5
Red alert — escalated to management
When coverage falls below the red threshold — typically 3 days — HublerX escalates to the procurement manager and plant manager simultaneously, with the specific WOs that will stop and the time remaining to prevent it. Every available option — emergency PO, inter-plant transfer, alternate material substitution — is surfaced in the alert.
On red threshold breach
6
Coverage restored and alert closed
When the coverage is restored — by a GRN, a confirmed PO ETA, or an inter-plant transfer — the alert is closed and the coverage timeline returns to green. The action taken, the time from alert to resolution, and the production impact (if any) are recorded in the monitoring log for the monthly supply chain review.
