Production processes common mistakes

Common mistakes

• Confusing job production with batch production

  Assuming job production can handle large volumes efficiently.

  Fix itJob production is suited to low volume, customised orders; batch production handles moderate volumes with some standardisation.

• Assuming flow production is always cheaper

  Thinking flow production is cheaper in all cases.

  Fix itFlow production is cheaper only for high‑volume, standardised products. For low‑volume, customised items, job production can be more cost‑effective due to lower setup and changeover costs.

• Confusing waste with cost

  Students often think waste is the same as cost.

  Fix itWaste refers to activities that do not add value to the product or service, regardless of their monetary cost. It is the source of inefficiency, not the cost itself.

• Misunderstanding JIT as zero inventory

  Assuming JIT means no inventory at all.

  Fix itJIT aims to minimise inventory, not eliminate it; a small safety stock is still required to protect against supply disruptions.
