Operations Methods
The method by which a business organises the production of its goods or services is one of the most fundamental operational decisions it makes. Three distinct production methods are used across different industries: job production, batch production, and flow (mass) production. Each reflects a different balance between customisation and standardisation, unit cost and flexibility, and capital versus labour intensity.
Job production
Job production involves producing a single unique item or very small number tailored to a specific customer's requirements. Examples: a bespoke suit made to a customer's measurements; a custom-designed building; a consulting project delivered to a specific brief; handcrafted furniture made to order.
Advantages: Fully customised to exact specification, commanding a premium price. Workers are typically more engaged — each item is different and requires skilled craftsmanship or intellectual effort. Minimal waste from overproduction — items are only made when ordered.
Limitations: High unit costs — no economies of scale, each item requires its full share of skilled labour time. Production is slow. Quality consistency can vary. Revenue is volatile if custom orders are inconsistent.
Batch production
Batch production involves producing a defined quantity of identical items, then switching to a different product or variant. Each batch moves through production stages together. Examples: a bakery producing 200 sourdough loaves then reconfiguring for ciabatta; a clothing manufacturer running 500 size-M shirts before switching to size L; a pharmaceutical company producing one formulation before cleaning equipment and producing another.
Advantages: Lower unit costs than job production — fixed set-up costs spread across the batch. More flexible than flow production. Equipment can be shared across different products.
Limitations: Idle changeover time between batches — a direct cost and source of inefficiency. Work-in-progress inventory accumulates between stages, consuming working capital. Unsold batch stock ties up cash.
Flow (mass) production
Flow production involves continuous, uninterrupted production of identical items, each moving through sequential stages without stopping. Examples: a car assembly line; a bottling plant filling thousands of containers per hour; a semiconductor fabrication plant.
Advantages: Very low unit costs through extreme economies of scale — fixed costs spread across enormous volumes; automation reduces direct labour cost per unit. Consistent, standardised quality. High output rates. Predictable throughput enables accurate supply chain planning.
Limitations: Very high capital investment required. Inflexible — switching products requires significant downtime and retooling investment. Workers perform highly repetitive tasks — motivation and engagement challenges. Vulnerable to single-point-of-failure disruptions. Only viable at very high, predictable output volumes.
| Feature | Job | Batch | Flow |
|---|---|---|---|
| Volume | One or very few | Limited groups | Very high, continuous |
| Customisation | Fully bespoke | Standardised within batch | Identical, standardised |
| Unit cost | High | Medium | Low |
| Flexibility | Very high | Medium | Very low |
| Worker skill | High — craft or professional | Medium | Low (line); High (maintenance) |
Meridian operates across all three production methods simultaneously. Its bespoke logistics consultancy projects — customised warehousing solutions for specific clients — are job production: unique, premium-priced, delivered by specialists. Its hardware division, producing tracking units in runs of 500–2,000 per batch with different firmware and casing variants, operates on batch production. Its automated cargo label printing facility — hundreds of thousands of identical labels daily with minimal human intervention — is flow production. This illustrates that a single business may use all three methods across different products, matching method to volume, customisation requirement, and cost structure.
Key Takeaways
- Job production: unique items, high unit cost, high customisation, high worker skill — appropriate for premium bespoke products and services.
- Batch production: defined quantity of identical items before switching — medium unit cost, medium flexibility — appropriate for a range of variants at moderate volume.
- Flow production: continuous standardised output — very low unit cost, very low flexibility, very high capital investment — appropriate only at very high, predictable volumes.
- The choice should match volume demanded, degree of customisation required, and capital resources available.
- A large business may use all three methods simultaneously across different product lines — no single method is universally optimal.
