4.1 Production of Goods & Services — Business 0450 Revision

Summary of Key Concepts

Production is the transformation of resources (labour, materials, capital) into finished goods or services that add value.
Productivity measures efficiency—how much output is produced per unit of input. Higher productivity means lower costs.
Lean production minimises waste and resources through Just in Time stock control and Kaizen (continuous improvement).
Three main production methods: Job (customised, one-off), Batch (groups of products), and Flow (continuous mass production).
Choice of method depends on demand, market, product nature, labour costs, and business size.
Technology like CAD and 3D printing is transforming what's possible in production—enabling faster design, better customisation, and lower costs.

1. The Meaning of Production

What is Production?

Production is the transformation of resources into finished goods or services. Think of it as the process where a business takes raw materials, labour, and capital equipment, and combines them to create something a customer wants and will pay for.

Production

The process of converting inputs (raw materials, components, labour, capital equipment) into outputs (finished goods or services) that add value to the original materials.

Goods vs Services

It's important to understand the difference because businesses manage each differently:

Goods

Physical, tangible products that can be touched, stored, and transported. Examples: bicycles, T-shirts, smartphones, furniture.

Services

Non-physical, intangible offerings that are delivered directly and cannot be stored. Examples: hairdressing, tourism, healthcare, education, banking.

💡 Why does this matter? Goods can be manufactured in advance and stored in a warehouse. Services must be delivered "on demand"—a haircut only happens when the customer is in the salon. This affects how production is planned.

The Purpose of Production: Adding Value

The whole point of production is to add value to raw materials. When a business buys flour, sugar, and butter for £5 and sells a cake for £20, it has added £15 of value through production and branding.

This is how businesses make profit:

Raw materials + Labour + Overheads → Finished product → Sold to customer £100 worth (e.g. flour, sugar) (added value) for £150 Profit = Revenue (£150) − Total costs (£100) = £50

Operations Management

The process of designing, controlling, and improving the production process. It oversees everything from sourcing raw materials to delivering the final product to customers, ensuring the process is efficient, cost-effective, and meets quality standards.

Key insight: Operations management is like the "engine" of a business. If it runs smoothly, the business is competitive and profitable. If it's inefficient, costs rise and the business struggles.

Practice Question 1

A furniture company buys wood for £2,000 and produces chairs that sell for £5,000. What is the added value created by production?

2. Production vs Productivity—Don't Confuse Them!

These two terms sound similar but mean completely different things. Examiners love testing whether students understand the difference.

Production

The act of making—the actual output. "We produced 3 cans of soup." It's a measure of output, not efficiency.

Productivity

A measure of efficiency—how much output is produced per unit of input. "We produced 3 cans of soup using 2 workers, so productivity is 1.5 cans per worker." It shows how effectively resources are being used.

Real-world example:
• A factory produces 1,000 phones in a day with 50 workers.
• Productivity = 1,000 ÷ 50 = 20 phones per worker per day.
• After training, the same 50 workers produce 1,200 phones.
• New productivity = 1,200 ÷ 50 = 24 phones per worker per day.
• Production increased (1,000 → 1,200), AND productivity improved (same workers, more output).

Labour Productivity Formula

Labour Productivity = Output ÷ Number of Workers

This tells you how many units each worker produces on average. Higher numbers mean workers are more efficient.

How to Improve Productivity

There are two main ways to boost productivity, both of which reduce cost per unit:

METHOD 1: Increase output with same inputs • Better worker training • Introduce financial incentives • Upgrade technology/machinery • Improve working practices → Same workers make more products METHOD 2: Maintain output with fewer inputs • Automate parts of production • Reduce wasted materials • Streamline processes → Fewer workers make the same products

💡 The big benefit: When productivity improves, the cost per unit falls. This lets a business either lower prices to gain market share OR keep prices the same and earn higher profits. Either way, the business becomes more competitive.

Worked Example: Calculating Productivity

Sokkemani Sock Production

Context: Sokkemani makes luxury wool socks. In 2021, they employed 50 staff and produced 46,000 pairs. In 2022, they employed 60 staff (20% increase) and produced 69,000 pairs. Calculate productivity in both years.

Step 1: Calculate labour productivity for 2021.

Labour Productivity = 46,000 ÷ 50 = 920 pairs per worker

Step 2: Calculate labour productivity for 2022.

Labour Productivity = 69,000 ÷ 60 = 1,150 pairs per worker

Step 3: Compare and interpret.

Productivity increased from 920 to 1,150 pairs per worker. That's a 25% improvement! Even though Sokkemani hired more workers, each one became more productive—likely due to better training, improved processes, or new machinery.

Practice Question 2

A bakery produces 1,200 loaves of bread per day with 8 workers. After investing in a new oven, they produce 1,500 loaves per day with the same 8 workers. Calculate the productivity before and after, and explain what improved.

3. Efficiency, Competitiveness & Inventory

What is Efficiency?

Efficiency

The ability to use production resources as cost-effectively as possible. It's measured by average cost per unit—the lower the cost per unit, the more efficient the business.

Average Cost Per Unit

Average Cost Per Unit = Total Costs ÷ Number of Units Produced

This shows how much it costs to make one product on average. A business wants this number to be as small as possible.

The Link: Efficiency → Competitiveness → Success

Here's why efficiency matters so much in business:

Efficient production (low cost per unit) ↓ Can lower prices OR increase profit margins ↓ More competitive in the market ↓ Gain more sales & market share ↓ Generate more profit ↓ Can invest in further improvements ↓ Long-term success & survival

Real example: Suppose two phone makers both spend £100m on production. Company A makes 10 million phones (cost: £10 each). Company B makes 12 million phones (cost: £8.33 each). Company B is more efficient. They can undercut Company A's price and take market share, or sell at the same price and make more profit. Either way, efficiency wins.

Why Businesses Hold Inventory (Stock)

You might think, "Why not just make products as customers order them?" Good question. There are real reasons businesses hold stock:

Type of Inventory	Why It's Held	Example
Raw Materials	To prevent production delays when suppliers are late or unreliable	A baker keeps flour & sugar in stock even between orders
Work-in-Progress	Products partway through production; necessary to keep the pipeline moving	Car parts on a production line waiting for the next assembly stage
Finished Goods	To meet customer demand without delay; prevents "stockouts" (losing sales)	A supermarket keeps shelves stocked with bread and milk

Reasons for Holding Inventory

✓ Prevent stockouts and lost sales
✓ Take advantage of bulk purchasing discounts
✓ Buffer against supply chain delays
✓ Ensure continuous production even with delivery uncertainty

⚠️ The trade-off: Holding too much inventory costs money. Warehousing is expensive, and stock can become damaged, obsolete, or go out of fashion. Businesses must find the sweet spot—enough stock to avoid disruption, but not so much that storage costs eat into profit.

4. Lean Production: Doing More With Less

What is Lean Production?

Lean Production

An approach that minimises the use of resources in production by cutting out all forms of waste. The aim is to produce the right product, in the right quantity, at the right time, using the minimum of labour, materials, and space.

Lean production typically involves less time, fewer materials, less labour, less space, and close relationships with a small number of trusted suppliers. The result is lower unit costs and better quality.

💡 Key insight: Lean isn't about being "cheap." It's about being smart. Lean businesses eliminate waste so thoroughly that they can offer better quality at lower prices—a powerful competitive advantage.

Just in Time (JIT) Stock Control

Just in Time (JIT)

A stock management system where raw materials are NOT stored onsite but are instead ordered and delivered by suppliers exactly when they are needed for production. This requires precise coordination and close supplier relationships.

JIT: Advantages & Disadvantages

Advantages	Disadvantages
Stockholding costs eliminated No expensive warehousing or storage	No bulk-buying discounts Small frequent orders cost more per unit
Cash flow improves Money not tied up in idle stock	Can't respond to sudden demand spikes No buffer if customer orders surge
Less waste Stock doesn't become obsolete or damaged	Increased admin costs Constant ordering and coordination
Space available for production Unused warehouses can become workshops	Supplier reliability is critical One late delivery halts production
Close supplier relationships Better quality & communication	Suppliers must be nearby Limits choice and increases transport pressure

Real-world challenge: During the COVID-19 pandemic, JIT supply chains broke down. Factories in the UK couldn't get components from Japan or China. Companies realised that "just in time" works perfectly in stable conditions but is fragile in crises. Many are now rebuilding some inventory as insurance.

Kaizen: Continuous Improvement

Kaizen

A Japanese concept meaning "continuous improvement." It's the practice of making small, ongoing improvements to production processes rather than waiting for one big, disruptive change. Everyone in the business—from shop floor workers to managers—is involved in spotting and fixing inefficiencies.

KAIZEN (Continuous improvement) vs ONE-OFF IMPROVEMENTS Small steps every week Big overhaul every few years ↓ ↓ Output per worker improves gradually Output jumps after overhaul ↓ ↓ Steady competitive advantage Temporary competitive advantage ↓ ↓ Staff engaged in problem-solving Staff disrupted; change resistance ↓ ↓ Long-term culture of improvement Back to old habits after a while

Elements of Kaizen

✓ Zero defects in manufacturing—every product is right first time
✓ High levels of automation—machines do repetitive tasks
✓ Worker-management cooperation—everyone contributes ideas
✓ Staff training & computer systems—fewer errors, better tracking
✓ Long-term management commitment—change is ongoing, not a one-off project

Exam tip: Don't confuse Kaizen with JIT. JIT is about when stock arrives. Kaizen is about how to continuously improve the process itself. A business can use both.

The Seven Wastes Eliminated in Lean Production

Lean production targets seven specific types of waste. Understanding these helps you evaluate whether a production system is truly lean:

Type of Waste	Definition	Example
1. Transportation	Unnecessary movement of materials or products	Moving goods between distant warehouses instead of producing near the customer
2. Inventory	Excess stock of raw materials, work-in-progress, or finished goods	Holding months' worth of fabric when you only need weeks' worth
3. Motion	Unnecessary movement of people or equipment within production	Workers walking back and forth to fetch tools instead of having them at each workstation
4. Waiting	Idle time or delays in the production process	Workers waiting for parts to arrive, or machines sitting idle between jobs
5. Overproduction	Making more than customers actually need	Manufacturing 1,000 units when only 800 orders exist; the extra 200 sit in a warehouse
6. Overprocessing	Using more resources or steps than necessary	Adding unnecessary features that customers don't want or won't pay for
7. Defects	Products or services that don't meet customer requirements	Making a phone with a faulty screen; wasting materials and labour

Benefits of Lean Production

PRODUCE MORE WITH SAME RESOURCES → REDUCED COSTS & LOWER PRICES • Train staff better • Undercut competitors • Improve working practices • Gain market share • Introduce incentives • Improve brand recognition • Maintain machinery • Increase profit margins → ↓ RAISE PRODUCTIVITY → RAISE COMPETITIVENESS

Practice Question 3

A car manufacturer stores 6 months' worth of steel in its warehouse at a cost of £500,000 per month. The factory manager proposes switching to Just in Time (JIT) to save storage costs. What are two risks of this decision?

5. The Three Main Production Methods

Businesses choose how to organise production based on what they're making and for whom. There are three main methods, each with distinct advantages and disadvantages.

1. Job Production

Job Production

Manufacturers produce one product at a time, customised to each customer's order. Every job is unique. Examples: bespoke wedding dresses, custom-built houses, made-to-order kitchen extensions.

Job Production: Pros & Cons

Advantages	Disadvantages
High quality Bespoke products attract customers willing to pay premium prices	Slow production One item at a time takes much longer than mass production
Motivated, highly skilled workers Craftspeople take pride in unique work	High labour costs Skilled workers command high wages, and there's little automation
Customisation possible Customers get exactly what they want, creating loyal, high-value relationships	High cost per unit No economies of scale; every project starts from scratch

When to use Job Production: When customers value uniqueness and quality over price. Think luxury goods, professional services, bespoke furniture. The target market is small but willing to pay well.

2. Flow Production

Flow Production

Continuous manufacturing of standardised products, usually on a production line. Products move from one workstation to the next in a continuous stream. Examples: car assembly lines, smartphone factories, soft drink bottling plants.

Flow Production: Pros & Cons

Advantages	Disadvantages
Low unit costs Economies of scale; fixed costs spread over millions of units	Customisation is difficult or impossible All products identical; expensive to retool for variations
Rapid production High output per day/week	Capital equipment is expensive Factory must be automated; high upfront investment
Usually highly automated Few workers needed, reducing labour variability	If line breaks down, entire factory stops No flexibility; equipment failure = lost production
	Worker repetition & boredom Monotonous tasks can lower morale and quality

When to use Flow Production: When demand is high and constant, the product is standardised, and price is a key selling point. Think mass-market goods: cars, phones, clothing, food. Requires significant capital investment but pays off through volume.

3. Batch Production

Batch Production

Groups of the same product are produced together as a batch, then the machinery is retooled for the next batch. Examples: baking 1,000 blueberry muffins, printing 5,000 copies of a magazine, making 500 units of a seasonal product.

Batch Production: Pros & Cons

Advantages	Disadvantages
Worker specialisation Workers become efficient at one task before changing to the next batch	Requires careful coordination Must schedule batches to avoid stockouts or excess inventory
Flexible Can produce different products; retool machinery between batches	Money tied up in stock Each batch must be completed and stored before sale
Lower cost than job production Some economies of scale; better than one-off items	Completed products need storage space Warehousing costs if stock doesn't sell quickly
Production can start as previous batch runs out No downtime between batches	Higher cost than flow production Retooling machinery between batches is time and cost

When to use Batch Production: When you want flexibility but better efficiency than pure job production. It's the "middle ground"—suitable for seasonal products, niche markets, or businesses that make multiple product lines. Typical for small to medium-sized manufacturers.

Comparing the Three Methods

Factor	Job	Batch	Flow
Customisation	✓✓✓ High	✓ Limited	✗ None
Cost per unit	✗ Very high	✓✓ Medium	✓✓✓ Low
Output speed	✗ Slow	✓✓ Medium	✓✓✓ Fast
Worker skill required	✓✓✓ High	✓✓ Medium	✓ Low
Capital investment	✗ Low	✓✓ Medium	✓✓✓ High
Inventory needed	✗ None	✓✓ Moderate	✓✓✓ High

Practice Question 4

A jewellery maker wants to expand. Currently, they custom-make each piece (job production) and can't keep up with demand. What production method would you recommend, and why? Consider the target market (luxury, bespoke jewellery) and the business goal (expansion).

6. Factors Affecting the Choice of Production Method

No single method is "best." The choice depends on several interconnected factors. Understanding these helps you recommend the right method for any business scenario.

Seven Key Factors

1. Level of Demand

The Factor

High demand justifies investment in flow production's expensive equipment, because you'll spread costs over millions of units. Low demand means you can't justify this capital, so job or batch production is more sensible.

2. Nature of the Target Market

The Factor

Price-sensitive markets (budget-conscious customers) need low unit costs → flow production. Quality-focused or luxury markets value customisation and uniqueness → job or batch production.

Example: Discount supermarket = flow production (cheap, fast). Luxury boutique = job production (bespoke, high-end).

3. Nature of the Product

The Factor

Some products can only be made one way. A house or a ship requires job production—you can't mass-produce them on a line. A microchip or a soft drink bottle is designed for flow production.

4. Comparative Costs of Labour vs Capital

The Factor

In rich countries with high wages, businesses invest in automation (flow production) to replace expensive workers. In developing countries with cheap labour, job or batch production makes sense because paying workers is cheaper than buying machines.

Example: A UK car factory invests in robots (capital) to replace workers. A factory in Vietnam or India hires more workers (cheap labour) to do assembly by hand.

5. Nature of the Firm Itself

The Factor

Small firms lack capital to invest in expensive flow production equipment, so they use job or batch production. Large firms with access to capital can afford to build automated factories.

6. New Technologies

The Factor

As technology becomes cheaper (e.g., 3D printers, automation software), smaller firms gain access to tools previously only large firms could afford. This shifts the competitive landscape and enables smaller businesses to increase production volume.

7. Goals of the Business

The Factor

A business seeking to maximise market growth and profit invests in flow production to dominate through low prices and high volume. A business seeking a niche market or brand positioning may stick with job or batch production for exclusivity.

Example: Apple (job/batch production early on, emphasising design) vs. Samsung (flow production, dominating through volume and competitive pricing).

Can Businesses Change Methods?

Yes. As a business grows, it often changes production methods:

STARTUP / SMALL BUSINESS (Low demand, limited capital) ↓ Job or Batch Production ↓ GROWTH PHASE (Demand rising, can invest in equipment) ↓ Batch or Flow Production ↓ MATURE / MARKET LEADER (High demand, maximum efficiency needed) ↓ Flow Production (highly automated)

Practice Question 5

A coffee roaster in the UK currently buys specialty beans and roasts them in small batches, selling to local cafés and restaurants (batch production). Market demand is growing, and they've been approached by a large supermarket chain to supply 100,000 bags per month. What production method should they adopt, and what factors support this decision?

7. The Impact of Technology on Production

New technologies are revolutionising what's possible in manufacturing. Two key technologies deserve special attention in your exams:

1. Computer Aided Design (CAD)

CAD (Computer Aided Design)

Using computers to design products. Instead of hand-drawing blueprints, designers use software to create digital 3D models. This speeds up design, improves accuracy, and makes it easy to share ideas across teams—even globally.

Key Benefits of CAD

Benefit	How It Works
Improved accuracy	CAD reduces human error in measurements and design. Tolerances are precise; nothing is guesswork.
Faster design process	Designers modify digital models in seconds, not days. Testing and iteration happen quickly on-screen.
Easy modifications	Designs can be adjusted, duplicated, or scaled with minimal effort. "What if?" questions are answered instantly.
3D modelling & visualisation	Designers and clients can see a realistic 3D preview of the final product before manufacturing starts. Catches flaws early.
Better collaboration	CAD files are shared digitally. A designer in London, an engineer in Germany, and a manufacturer in Japan all see the same designs in real-time.
Faster product development	All of the above combine to bring new products to market weeks or months faster than traditional methods.
Easier customisation	CAD makes it simple to tweak designs for individual customers—bridging job and flow production.

Exam insight: CAD is a design technology, not a production technology. It doesn't make the products itself; it makes designing and planning faster and better. When paired with CAM (Computer-Aided Manufacturing), the digital design feeds directly into the production system.

2. 3D Printing

3D Printing

A manufacturing process where digital designs are uploaded to a 3D printer, which produces the product layer by layer using plastic, metal, resin, or other materials. No moulds, no tooling—just the design and the printer.

How 3D Printing Impacts Production

Impact	Traditional Manufacturing	3D Printing
Cost	Requires expensive moulds, dies, and tooling. High upfront cost; only worthwhile for large volumes.	No tooling needed. Cost is the same whether you print 1 unit or 1,000. Perfect for small runs and customisation.
Productivity / Lead Time	Long lead times for tooling delays production. Takes weeks to get started.	Quick production with minimal lead times. Upload the design, and printing starts immediately.
Market Responsiveness	Hard to respond to demand spikes or new customer tastes; retooling is expensive and slow.	Can quickly produce new designs or adapt existing ones. Perfect for fast-changing markets.
Quality	Good for complex shapes, but limited by moulds and tooling constraints.	Can produce precise, complex designs (intricate parts, internal channels, unusual geometries) that traditional manufacturing can't easily replicate.
Flexibility / Customisation	Customisation means new moulds = expensive and slow.	Each print can be unique. Customers can order fully customised products cost-effectively.

Real-World Uses of 3D Printing

Current applications include:
• Car engines: Some manufacturers print metal engine components.
• Houses: Companies are printing affordable homes (walls, structural components).
• Food: Custom cakes, chocolates, and food shapes.
• Medical: Custom prosthetics, implants, and surgical models.
• Aerospace: Light, strong, complex parts for aircraft.

The Broader Impact: Reshaping Production

CAD and 3D printing together represent a shift in how manufacturing works:

TRADITIONAL MODEL → NEW MODEL (CAD + 3D Printing) Large volumes justify tooling → Small runs & customisation viable Design → Approval → Tooling → Design → Direct to production (weeks/months) (hours) One product design per → Many variations possible expensive mould for same design Mass production needed to → Niche, customised products succeed can be profitable Centralised factories in → Distributed manufacturing low-cost countries → (Print locally, near customers)

Exam tip: When asked about technology's impact, consider all angles: speed, cost, quality, flexibility, and markets enabled. Don't just say "faster"—explain why faster matters (markets change, customisation possible, etc.).

Practice Question 6

A small business makes custom prosthetic limbs. Currently, they craft each one by hand (job production). A new 3D printing technology allows them to design a limb digitally, then print it in titanium, and customise fit with software adjustments. What are three ways this technology improves their business?

Exam Tips & Common Mistakes

Common Misconceptions

❌ Mistake 1: Confusing Production and Productivity
"The factory produced 1,000 units" is about production (output). "The factory's productivity is 100 units per worker" is about efficiency (output per input). They're not the same. Examiners will test this distinction.

❌ Mistake 2: Thinking JIT Always Works
JIT is brilliant in stable, predictable supply chains. But it breaks down if suppliers are unreliable or demand spikes suddenly. Always discuss both advantages and disadvantages when JIT is mentioned.

❌ Mistake 3: Recommending One Production Method Without Considering Context
Never just say "Flow production is best." Instead, analyse the business: Is demand high or low? Is the target market price-sensitive or quality-focused? Is the business large or small? Then recommend based on these factors.

❌ Mistake 4: Saying Technology Always Solves Everything
Yes, 3D printing is amazing, but it has limitations: it's slow for very high volumes, material costs are high, and not every product can be 3D-printed. Discuss trade-offs, not just benefits.

What Examiners Look For

✓ Define terms precisely. Don't just say "productivity is output." Say "productivity is the amount of output produced per unit of input, measured as a ratio of output to inputs."

✓ Use formulas correctly. If a question asks you to calculate labour productivity, show the formula, substitute the numbers, and state the answer with units.

✓ Evaluate, don't just list. When asked about advantages and disadvantages, explain why each matters and in what context. "JIT saves storage costs" is okay. "JIT saves £500,000 per month in warehousing, which improves cash flow and competitiveness, but only if suppliers are reliable" is much better.

✓ Recommend with justification. Don't say "Use job production." Say "Use job production because the customers value customisation and are willing to pay premium prices, the market is niche, and the business is small without capital for automation."

✓ Consider business context. A recommendation that makes sense for a startup may not make sense for a global corporation. Show you understand the bigger picture.

Typical Exam Questions You Might Face

Question Type	What You Need to Do	Marks Awarded For
Define production/productivity	State the definition clearly and concisely. Give an example if space allows.	1–2 marks: definition correct and in own words
Calculate labour productivity	Show the formula, substitute numbers, state answer with units.	3 marks: formula (1), calculation (1), answer with units (1)
Evaluate JIT advantages/disadvantages	List at least 4 (2 advantages, 2 disadvantages) with brief explanations of why they matter.	4–6 marks: breadth (multiple points) and depth (explanation of impact)
Recommend production method with justification	State which method (job/batch/flow), then list 3–4 factors (demand, market, product, costs, firm size) and explain why they support your choice.	5–8 marks: correct recommendation + 2–3 well-explained justifications
Compare two production methods	Use a table or prose to address cost, speed, customisation, skill needed, capital required, flexibility. State which is "better" in context.	4–6 marks: multiple points of comparison, context-aware conclusion
Discuss impact of technology (CAD/3D printing)	Explain how it changes cost, speed, quality, customisation, or market reach. Consider both benefits and limitations.	4–6 marks: multiple impacts identified, depth of explanation, balanced view

Exam Strategy

Read the scenario carefully. Examiners include details (firm size, market type, demand level, product type, labour costs) that point toward the "right" answer. Extract and use these clues in your recommendation.

Structure your answer. For recommendations, use this format:
1. State the method you recommend
2. List factors that support this (demand, market, product, costs, etc.)
3. Briefly mention why alternatives are less suitable

Use precise language. "Productivity is higher" is vague. "Labour productivity increased from 50 to 60 units per worker, a 20% improvement, because of training and better equipment." Much better.

Show working for calculations. Always show the formula and substitution, even if you know the answer. Partial credit exists—if your calculation is wrong but your formula is correct, you get marks for method.

Final Practice Challenge

Integrated Scenario

"TechWear Ltd is a UK clothing manufacturer founded 8 years ago. They currently specialise in high-end athletic wear sold to gyms and boutique sports retailers. Demand for their products has grown 30% year-on-year, and they now employ 80 workers in a batch production setup. Their labour costs are high (UK wages), and they've struggled to keep inventory levels balanced—sometimes they have too much stock, sometimes stockouts. A large online retailer has offered them a contract to supply 50,000 units per month of a standardised athletic t-shirt, with a lead time of just 12 weeks. To accept this, TechWear must make significant changes.

(a) Explain why TechWear's current batch production method is no longer suitable for this opportunity.

(b) Recommend a new production method and justify your choice using at least three factors (level of demand, nature of market, nature of product, labour costs, or firm size).

(c) The company is considering investing in automation (robots) and 3D printing technology. Discuss two ways this technology would support the new production method you've recommended.
