What are the three methods of production?

Job production makes one unique item at a time to a customer's order (high quality but slow and costly per unit). Batch production makes a group of identical items together before switching to a different batch (some variety but time is lost switching). Flow production makes large quantities of an identical product continuously on a production line (fast and very low cost per unit, but inflexible).

What is the difference between quality control and quality assurance?

Quality control means checking and inspecting products at the end of production to find and remove faulty ones; it catches faults but only after they happen. Quality assurance means building quality in at every stage, with each worker responsible for their own work, so faults are prevented rather than just caught, aiming to get it right first time and reduce waste.

What is the difference between just-in-time and just-in-case stock control?

Just-in-time (JIT) holds little or no stock and orders supplies to arrive exactly when needed, saving storage costs and waste but relying completely on reliable suppliers. Just-in-case (JIC) holds a buffer of spare stock so production can continue if a delivery is late or demand rises suddenly; it is safer but ties up more money in storage.

Why is customer service important?

Good customer service makes customers feel valued, so they return and recommend the business, builds a strong reputation and helps the firm stand out from rivals. It covers friendly, knowledgeable staff, quick and accurate service, clear information, easy contact and handling complaints, plus after-sales service such as warranties and repairs. Poor service drives customers to competitors.

How does technology improve business operations?

Technology improves operations through stock systems that track inventory and reorder automatically, machinery and computers that make production faster and more accurate, and websites and apps that let customers order and get help around the clock. Online chat, email and self-service speed up customer support. It can cut costs and raise efficiency, though it needs investment and training.

How should I revise the business operations topic?

Learn the three production methods with an example and the pros and cons of each, and be ready to recommend one for a given product. Drill the key contrasts: job versus batch versus flow, quality control versus quality assurance, and just-in-time versus just-in-case. Practise the productivity calculation, and link quality, the supply chain and customer service to cost, reputation and sales.

What this covers

Business operations (production) is the key business function that makes the goods or delivers the services. This overview ties the dot points together: methods of production, quality, the supply chain and procurement, and customer service and technology. Operations is where adding value happens, so it decides the cost, the quality and how much a business can make, which feeds straight into marketing and finance.

Methods of production

There are three methods. Job production makes one unique item to order (high quality and customisation, but slow and costly per unit). Batch production makes a group of identical items then switches to another batch (some variety, more efficient than job, but time is lost switching). Flow production makes large quantities of an identical product continuously (fast, very low cost per unit, but inflexible and expensive to set up). Productivity is output per worker, and raising it (through training, machinery or motivation) lowers the cost per unit and makes a firm more competitive.

Quality and the supply chain

Quality means meeting customer needs and expectations. Quality control checks at the end to catch faults; quality assurance builds quality in throughout to prevent them. High quality brings reputation, loyalty, a higher price and lower waste. The supply chain is the network that gets a product from raw materials to the customer, and procurement is buying supplies; firms choose suppliers on price, quality, reliability and delivery. Stock control balances having enough to produce against the cost of storage, using just-in-time (little stock, reliant on suppliers) or just-in-case (a safety buffer).

Customer service and technology

Customer service is how a business looks after customers before, during and after a sale, including after-sales service such as warranties and repairs. Good service builds loyalty, reputation and repeat custom. Technology improves operations through automatic stock systems, faster and more accurate production, and websites and apps that let customers order and get help around the clock. Like quality, good service and technology cost money in training and systems, so the gain is weighed against the cost.

Business operations is the function that makes the goods or delivers the service in WJEC GCSE Business. There are three production methods: job (one unique item to order, high quality but costly per unit), batch (groups of identical items, some variety but time lost switching) and flow (large quantities made continuously, fast and cheap per unit but inflexible). Productivity is output per worker, and raising it lowers the cost per unit. Quality means meeting customer expectations: quality control checks at the end to catch faults, while quality assurance builds quality in throughout to prevent them, bringing reputation, loyalty and lower waste. The supply chain gets a product from raw materials to the customer, procurement is buying supplies, and firms choose suppliers on price, quality and reliability; stock control uses just-in-time (little stock, reliant on suppliers) or just-in-case (a safety buffer). Customer service, including after-sales support, builds loyalty and reputation, and technology improves operations through automatic stock systems, faster production and 24/7 online ordering and support.

Solutions

Q1: Job, batch and flow production.
Q2: Very low cost per unit through economies of scale (also: fast, consistent quality).
Q3: The amount of output produced per worker (or per hour or machine).
Q4: Quality control inspects at the end to catch faulty products; quality assurance builds quality in at every stage to prevent faults, getting it right first time.
Q5: Any two of: a strong reputation and customer loyalty, ability to charge a higher price, fewer returns and waste, an edge over rivals.
Q6: Just-in-time holds little or no stock and orders as needed (cheap but reliant on suppliers); just-in-case holds a buffer of spare stock for safety (safer but ties up money).
Q7: The help and support given after a product is bought, such as warranties, repairs, technical support and returns.
Q8: For example automatic stock systems (or faster, more accurate production; 24/7 online ordering and support).
