Top 100 Vocabulary for Adults | Operations & Supply Chain
Operations vocabulary is the language of flow: demand entering a system, resources absorbing that demand, work moving through constraints, inventory waiting between stages, and customers experiencing the final service level. Supply-chain vocabulary adds the language of sourcing, logistics, continuity and risk across organisational boundaries.
This profession-specific flagship belongs to the eduKate Adult Vocabulary for Professionals system. It connects to Management and Business & Commerce, but owns the end-to-end language of flow, fulfilment and operational resilience.
The Four Banks
Demand & Planning: demand, forecast, plan, capacity, capability, workload, utilisation, schedule, sequence, priority, lead time, cycle time, throughput, bottleneck, queue, backlog, buffer, service level, target, variance, scenario, contingency, allocation, constraint, optimisation.
Supply & Inventory: supplier, vendor, sourcing, procurement, purchase order, contract, inventory, stock, safety stock, reorder point, replenishment, lot size, warehouse, fulfilment, distribution, logistics, transport, shipment, freight, delivery, receiving, traceability, batch, expiry, obsolescence.
Quality & Control: quality, defect, non-conformance, inspection, specification, tolerance, standard, process, workflow, control, root cause, corrective action, preventive action, variation, yield, scrap, rework, audit, compliance, reliability, maintainability, incident, escalation, monitoring, improvement.
Resilience & Performance: resilience, continuity, disruption, exposure, concentration, dependency, single source, diversification, recovery, redundancy, flexibility, agility, risk, mitigation, supplier risk, operational risk, cost, efficiency, productivity, fill rate, on-time delivery, OTIF, working capital, sustainability, trade-off.

Inventory Is Both Protection and Cost
Inventory protects against demand and supply uncertainty, but it consumes cash, space and attention. The right question is not “How do we minimise inventory?” but “Which uncertainty is this inventory protecting us from, and is there a cheaper way to control it?”
Scenario: Chronic Late Deliveries
Separate forecast error, supplier lead time, internal queue, transport delay, quality rework and unrealistic promise dates. Late delivery is an outcome; the bottleneck may sit far upstream.
Seven-Day Operations Vocabulary Plan
| Day | Practice |
|---|---|
| 1 | Map demand, capacity, queue and bottleneck for one process. |

| 4 | Map supplier and logistics dependencies. |
| 5 | Write one quality issue as defect, cause, corrective and preventive action. |

Conclusion
Operations and supply-chain vocabulary makes flow visible. It gives professionals a language for bottlenecks, variability, inventory, service, quality and resilience—and helps them improve the system rather than merely accelerate one local step.
