Inventory Control

Inventory Statuses Explained

Why “on hand” is not the same as available, serviceable or ready to issue.

What this means in practice

Inventory status separates physical possession from usability. Clear statuses prevent quarantined, damaged, allocated or repairable items from being promised as ready stock.

The useful question is not merely whether a quantity appears in a report. It is whether the quantity is correctly identified, in the right location and unit, in an approved status, and available at the time it is needed. Good material management makes those assumptions visible.

Information worth recording

A simple worksheet can be more reliable than a complicated report when the underlying assumptions are clear. Record at least the following:

  • on hand quantity
  • available quantity
  • allocated or committed quantity
  • quarantine or inspection quantity
  • repairable, damaged, expired or disposal quantity

Use one consistent time period and unit of measure. When information is uncertain, show it as an assumption or possible future supply instead of quietly treating it as confirmed.

A practical control sequence

  1. 1
    Define a small set of statuses with clear ownership.
  2. 2
    State which statuses count as available.
  3. 3
    Require a controlled reason for every status change.
  4. 4
    Review old quarantine and repair statuses.
  5. 5
    Reconcile status totals to the physical balance.

The sequence matters. Recording a balance correction without first checking the transaction, location, status and unit can make the report look cleaner while leaving the underlying process failure untouched.

Worked situation

Example

One hundred units may be physically present while only sixty are available: twenty are allocated, ten await inspection and ten are damaged. A report showing only “100 on hand” is operationally misleading.

The example is deliberately simplified. Real operations may have multiple locations, ownership rules, quality statuses, open commitments, repair loops and system interfaces.

Common failure points

  • creating dozens of overlapping status codes
  • allowing users to bypass inspection by changing status
  • counting “in repair” as serviceable
  • failing to age or review quarantined stock

Repeated errors deserve more attention than one isolated difference. Patterns by item, supplier, location, user, shift, pack size or transaction type can point to a correctable cause.

Limits and professional boundaries

Status definitions must match local processes and systems.
