Manufacturing technology and quality: production systems (job, batch and continuous-flow production); the use of technology and automation in manufacturing; quality control and quality assurance; and food-safety management, including hazard analysis (HACCP) and critical control points.

A 6-mark answer needs each system described and an example, two marks each.

Job production makes a single item or a small one-off order to a customer's specification, with skilled staff and little automation. It is flexible but slow and costly per item; an example is a one-off celebration or wedding cake made to order.

Batch production makes a set quantity (a batch) of identical products, then the equipment is cleaned and reset for the next batch, which may be a different product. It suits a range of products in moderate quantities; an example is a bakery making batches of different breads or a batch of a flavour of yoghurt.

Continuous-flow production runs the same product continuously, often 24 hours a day, on a highly automated line. It gives a very high output at low cost per unit but is inflexible; an example is a product such as bottled milk, breakfast cereal or canned soup made in huge volumes.

Markers reward two points each: (1 and 2) job is one-off, flexible, skilled and costly with a suitable example, (3 and 4) batch makes set quantities of identical items with resets and an example, and (5 and 6) continuous flow is high-volume, automated and low-cost per unit with an example.

A 5-mark answer needs the QC and QA distinction plus how HACCP works.

Quality control (QC) is checking the product, usually at the end or at points along the line, to find and remove items that do not meet the specification, for example weighing or inspecting samples and rejecting faulty ones. It detects problems.

Quality assurance (QA) is a system built into the whole process to prevent faults arising in the first place, by setting and following procedures, training staff and monitoring at every stage, so quality is "assured" rather than just checked at the end.

HACCP (Hazard Analysis and Critical Control Points) is a food-safety system. The manufacturer analyses the process to identify hazards (biological, chemical or physical), finds the critical control points where a hazard can be controlled (for example a cooking step that must reach a set temperature), sets safe limits, monitors them, and takes corrective action if a limit is breached. This prevents unsafe food being made.

Markers reward (1) QC checks the product to find faults, (2) QA builds prevention into the whole process, (3) HACCP identifies hazards, (4) sets and monitors critical control points with limits, and (5) takes corrective action so unsafe food is prevented.
