Inventory can support service and production continuity. It can also conceal weak demand, unstable scheduling and capital tied up in work that customers do not need.
Leaders should examine both the accounting value and the physical flow. Neither view is sufficient alone.
Understand the valuation basis
IAS 2 measures inventory at the lower of cost and net realizable value. Net realizable value considers the estimated selling price less completion and selling costs.
Inventory cost includes eligible purchase and conversion costs. For ordinarily interchangeable items, IFRS uses FIFO or weighted average; LIFO is not an IFRS cost formula.
Other frameworks can differ, so establish the basis before comparison.
The recorded amount is not necessarily the cash the company could obtain immediately by selling the stock.
Follow the effect on profit and cash
Purchasing or producing stock can absorb cash before the inventory is sold and its cost reaches the income statement.
Production accounting can also defer eligible costs in inventory. A favorable short-term cost result may therefore coexist with unnecessary stock and weaker cash generation.
Inventory reduction can affect the timing of recognized costs as well as operations. Finance and production should explain the bridge.
Do not reward output merely because it improves an allocated unit-cost measure.
Examine recoverability
Aging, damage, technical changes and lower selling prices can weaken the ability to recover cost.
Review finished goods, components and work in progress with relevant commercial and technical teams.
A hypothetical product redesign may leave components that are physically usable but have no likely demand. Their engineering condition does not establish economic recoverability.
Use evidence about future use, sale and completion cost. Avoid treating age alone as either proof of obsolescence or proof that nothing needs adjustment.
Separate necessary buffers from avoidable accumulation
Stock may protect against lead-time variation, unreliable supply or customer-service requirements.
Ask what each significant buffer is intended to protect and whether a better process could reduce the need.
Indiscriminate cuts can create shortages and expedite cost. Excessively cautious purchasing can lock in obsolete stock.
Segment by demand pattern, criticality and supply exposure rather than impose the same target on every item.
Connect measures to behavior
Inventory value, days of inventory, service performance and aging provide different information.
Calculate days using an appropriate cost basis and consistent period. A value reduction caused by a write-down is not the same operating achievement as selling or consuming stock.
Examine quantities, mix and flow alongside accounting value.
Changes in commodity prices, currency and acquisitions can move the balance without equivalent changes in physical efficiency.
Assign end-to-end responsibility
- Sales influences demand and customer variation.
- Engineering affects reuse and obsolescence.
- Purchasing influences order quantities and terms.
- Operations controls flow and scheduling.
A stock target owned only by finance can miss these causes.
Review slow-moving items, unstable plans and large commitments through a joint process. Assign decisions on disposition, design change or replenishment.
Inventory discipline means maintaining the right protection while reducing unnecessary capital and recoverability risk. Good reporting helps leaders see whether apparent efficiency reflects better flow or simply more costs waiting on the balance sheet.
