Operations methods: job, batch, flow, mass customisation — common mistakes

When evaluating job production, balance the key advantages of high quality and customisation against the significant disadvantages of high unit costs and slow production times. Consider the suitability of this method for niche markets where customers are willing to pay a premium for a unique product.

In exam answers, flow production's main evaluation point is the trade-off between efficiency and flexibility. Low unit costs are a huge advantage, but this comes at the price of being unable to adapt to changing market tastes or produce varied items. Always link this to the nature of the product and its market.

Yes, absolutely. A large business might use different methods for different products. For example, a car manufacturer might use flow production for its standard models but use job production in a specialist division to build a unique vehicle for a motorsport event. A restaurant might use batch production to prepare sauces and soups in the morning and job production to cook individual meals to order during service.

This is a common misconception. They serve different purposes. Flow production is designed for one single, unchanging product in high volume. Batch production's key strength is its ability to produce a variety of products using the same equipment. The 'inefficiency' of downtime between batches is the necessary price for the flexibility to offer a wider product range, which flow production cannot do.

Not quite. While both offer customisation, their core principles differ. Job production creates a truly unique 'one-off' item, often with high-skilled craft labour and high costs. Mass customisation operates on a larger scale, offering choice from a pre-set (though often large) menu of options and components. It uses automation to assemble these options efficiently, keeping costs much lower than traditional job production.
