The role of operations management: cost leadership, differentiation, goods and services, interdependence (HSC Business Studies Topic 1)
“Role of operations management: strategic role of operations management (cost leadership, good/service differentiation), goods and/or services in different industries, interdependence with other key business functions”
Operations management transforms inputs into goods and services. Its strategic role is to create a lasting competitive advantage through either cost leadership (lowest cost in the industry, from scale, automation, efficient supply chains and lean inventory) or good/service differentiation (a product customers value as unique, from design, quality, customisation and service). Operations differs across goods and services and across primary, secondary and tertiary industries, and it is interdependent with marketing, finance and human resources: each function relies on and shapes the others.

What this dot point is asking
The syllabus content is: "role of operations management: strategic role of operations management (cost leadership, good/service differentiation); goods and/or services in different industries; interdependence with other key business functions". The related "students learn to" points ask you to "describe the features of operations management for businesses in a tertiary industry", "assess the relationship between operations and the other key business functions in two actual businesses" and "explain how operations strategy can help a business sustain its competitive advantage".
Recent HSC papers test all three parts: interdependence (2024 Q21a, 3 marks), goods versus services (2025 Q21b, 2 marks), cost as a performance objective (2025 Q1) and cost leadership through global factors in the 2025 business report (Q25).
What operations management is
Operations management is the management of the process that transforms inputs (materials, information, customers, human resources and facilities) into outputs (goods and/or services) that meet customer needs and business objectives. Every business has an operations function: a steelworks, a bank, a hospital, a streaming service and a cafe all transform inputs into outputs. The detail of inputs, transformation and outputs is covered in operations processes.
The strategic role of operations
"Strategic" means long term and linked to the business's overall competitive position. Operations is strategic when decisions about technology, layout, suppliers, capacity and quality are made to support how the business chooses to compete. The syllabus names two generic strategies (from Michael Porter's work on competitive advantage).
Cost leadership
A business pursuing cost leadership aims to be the lowest-cost producer in its industry. It can then charge lower prices than competitors, or earn higher profit margins at similar prices. Cost leadership does not mean poor quality; it means acceptable quality at the lowest possible cost.
Operations strategies that support cost leadership:
- Economies of scale: spreading fixed costs over a high volume of output and using bulk-buying power.
- Automation and technology: replacing labour-intensive tasks with machines to lower cost per unit.
- Supply chain management: efficient logistics, distribution centres and supplier negotiation.
- Standardisation: limited ranges and standard processes reduce complexity and waste.
- Lean inventory: just-in-time delivery reduces holding costs.
- Global sourcing and outsourcing: using cheaper inputs or specialist providers.
Australian example: Coles Group's automated supply chain. Coles opened its first automated distribution centre (ADC), built with the German firm Witron, at Redbank in Queensland in 2023, and a second at Kemps Creek in western Sydney, officially opened in August 2024. In October 2024 it announced an $880 million automated ambient distribution centre at Truganina in Victoria. For online orders, Coles opened two automated customer fulfilment centres built with the UK technology company Ocado, at Truganina (Victoria) and Wetherill Park (NSW), in 2024. Automation lowers the labour cost of handling each carton and improves availability and accuracy, supporting a lower cost per unit and Coles' ability to compete on price.
Australian example: Bunnings (Wesfarmers). Bunnings competes on price with its long-standing promise that "lowest prices are just the beginning". Its operations support this with large warehouse-format stores, a wide but standardised range, and the purchasing volume of Australia's largest hardware retailer.
Good/service differentiation
A business pursuing differentiation offers a product that customers perceive as unique or better, for which they will pay a premium. Differentiation can come from design, features, quality, reliability, customisation, speed, customer service or brand.
Operations strategies that support differentiation:
- Quality management: quality assurance and continuous improvement (see quality management).
- New product or service design and development: research and development and innovation.
- Customisation and flexibility: processes that allow products to be tailored.
- Skilled labour and training: especially in services, where staff are part of the product.
- Leading-edge technology: to offer features competitors cannot.
Australian example: the Qantas Group's two brands. The Qantas Group runs Jetstar, launched in 2004, as a low-cost carrier and Qantas as a full-service premium carrier. Jetstar's operations emphasise cost: standardised service, paid add-ons such as checked baggage and meals, and high aircraft use. Qantas's operations emphasise differentiation: lounges, included meals and baggage, a frequent flyer program and a premium cabin product. One group, two operations strategies for two target markets.
Porter argued that businesses which try to be both lowest cost and most differentiated in the same market risk achieving neither. Large groups often resolve this by running separate brands or divisions with different operations strategies, as the Qantas and Jetstar example shows.
Sustaining competitive advantage
The syllabus asks how operations strategy helps a business sustain its advantage. Competitive advantage lasts when it is hard to copy: a large automated network, an established supplier base, deep know-how or a strong quality reputation takes years and heavy investment to replicate. Continuous improvement matters because competitors eventually catch up.
Goods and/or services in different industries
Goods versus services
| Feature | Goods | Services |
|---|---|---|
| Tangibility | Tangible: can be seen and touched | Intangible: an experience or activity |
| Storage | Can be stored as inventory (some are perishable) | Cannot be stored; produced and consumed at the same time |
| Customer contact | Often low; production is separate from consumption | Often high; the customer is part of the process |
| Standardisation | Easier to standardise and measure quality | Varies with staff and customers; quality harder to measure |
| Examples | Cars, furniture, packaged food | Banking, education, health care, air travel |
Most businesses provide a mix. A cafe produces goods (meals) and a service (the dining experience), as the 2025 HSC question highlighted. A car maker sells a good plus warranties and servicing.
Operations across industry sectors
- Primary industries extract or grow natural resources (mining, agriculture, fishing). Operations focuses on extraction, harvesting, equipment and logistics.
- Secondary industries manufacture goods from raw materials (steel, food processing, construction). Operations focuses on production processes, layout, quality control and inventory.
- Tertiary industries provide services (retail, finance, tourism, health, education). Operations focuses on customer contact, scheduling staff, service quality and technology.
- Some texts also describe quaternary (knowledge and information services) and quinary (high-level decision-making and human services) industries.
Features of operations in a tertiary industry
The syllabus asks you to "describe the features of operations management for businesses in a tertiary industry":
- High visibility. Customers are present during transformation, so layout, staff behaviour and waiting time are part of the product.
- Demand cannot be met from stock. Services are perishable, so variation in demand is managed through staffing, bookings, queue management and pricing (for example off-peak fares).
- Labour-intensive quality. Training, empowerment and consistent procedures drive quality.
- Technology changes service delivery. Online banking, self-service kiosks, apps and automated fulfilment shift some transformation to the customer or to machines.
- Quality is measured by the customer's experience: satisfaction scores, complaint rates, net promoter scores and service standards.
Interdependence with other key business functions
Operations, marketing, finance and human resources are the four key business functions. Interdependence means they rely on each other, so a decision in one affects the others. The NESA 2024 sample answer shows the standard: dependence in both directions.
Operations and marketing
- Marketing identifies what customers want and forecasts demand; operations must produce it at the right quality, quantity and time.
- Marketing's promises (price, delivery time, quality) must be deliverable by operations. A price promotion that operations cannot supply leads to empty shelves and disappointed customers.
- Operations capabilities (new features, faster delivery) give marketing new things to promote.
Operations and finance
- Operations is usually the largest user of funds: materials, wages, equipment and facilities. Finance raises and allocates capital, sets budgets and monitors costs.
- Finance depends on operations for the cost information (product specifications, cost of goods sold) that drives budgets and pricing, as NESA's 2024 sample answer noted.
- Operations decisions such as automation or outsourcing change the income statement and balance sheet.
Operations and human resources
- Operations needs the right number of skilled workers at the right time; HR recruits, trains, rosters and retains them.
- Changes in operations technology change job design, skills and staffing levels, which HR must manage, including retraining and redundancies.
- Poorly managed operations changes create disputes. In August 2025 the Federal Court ordered Qantas to pay a $90 million penalty for illegally outsourcing the jobs of about 1,820 ground handling workers during the COVID-19 pandemic, a decision made for operational cost reasons that breached the Fair Work Act and caused significant HR, legal and reputational costs. (See role of human resource management.)
- Stem
- A flag manufacturer's sales are rising before a major sporting event and the operations manager has increased everyone's working hours.
- Pick one function: marketing
- Operations depends on marketing's sales forecasts to know how many flags to produce and for how long the higher demand will last. Marketing depends on operations to produce enough flags, on time and to the promised quality, so that its promotions around the event can be fulfilled. If operations cannot keep up, marketing's campaign creates unmet demand and damages the brand.
- Why it scores 3
- It names one function, applies it to the flag business, and shows reliance in both directions.
Operations exists in every business, including banks, airlines, cafes and online retailers. Service examples are often easier to explain because the customer is part of the process.
Writing "operations works with marketing, finance and HR" is description, not explanation. For each pairing, show what each function needs from the other and what happens if it is not provided.
Cost leaders still meet customer expectations. The point is the lowest cost for acceptable quality, achieved through efficiency and scale.
How this dot point appears in the HSC
- Section I asks for definitions and applications: which performance objective or strategy a scenario shows, or which market type or industry a business belongs to.
- Section II asks you to outline goods versus services, explain interdependence for a stem business, or explain how operations supports cost leadership or differentiation (2 to 5 marks). Always apply to the business in the stem.
- Section III may ask you to recommend operations strategies or global factors to achieve cost leadership for a hypothetical business, as in 2025.
- Section IV may ask how operations contributes to competitive advantage or business success, where a well-researched case study such as Coles' supply chain automation earns the application marks.
Exam-style questions
Questions in the style of NESA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
2024 HSC Q21 (a)Past paper3 marksA manufacturer of flags has seen a steady increase in sales, which coincides with the start of a major sporting event. The operations manager has increased the working hours of all employees to meet this demand. Explain the interdependence between operations and ONE other key business function for this business.Show worked answer →
- NESA marking guidelines
- 3 marks: provides an explanation of the interdependence between operations and ONE other business function for this business. 2 marks: demonstrates some understanding of the interdependence. 1 mark: provides some relevant information. Answers could use finance, human resources or marketing.
- What the sample answer does
- It shows dependence in both directions: operations depends on finance to fund the extra overtime, electricity and fabric, and finance is guided by operations' product specifications, which determine how much money is required. That two-way link is what lifts a response from 2 to 3 marks.
- Model answer (human resources)
- Operations has increased the working hours of all employees, so it depends on the human resources function to organise overtime within the award or enterprise agreement, manage fatigue and work health and safety risks, and possibly recruit casual staff for the event period. In turn, HR relies on operations' production schedule to know how many extra hours and workers are needed and for how long, so it can plan rosters and labour costs. Each function's decisions shape the other's, which is interdependence.
2025 HSC Q21 (b)Past paper2 marksA cafe produces quality food and friendly, personalised service. It donates its left-over food to a local charity at the end of each day. Outline the difference between goods and services in this business.Show worked answer →
- NESA marking guidelines
- 2 marks: outlines the difference between goods and services in this business. 1 mark: provides some relevant information.
- NESA sample answer
- "The cafe produces meals (goods) that are perishable. Services can be customised or standardised. This cafe is known for its friendly service."
- Stronger version
- The cafe's goods are the meals and drinks: tangible products that can be seen and stored for a short time but are perishable, which is why leftovers are donated at the end of each day. Its service is the friendly, personalised interaction with customers: intangible, produced and consumed at the same time, and varying with each staff member, so it cannot be stored. Refer to the business in the stem to access both marks.
Original5 marksExplain how operations management can help a large business achieve a competitive advantage through cost leadership. Use a contemporary business example.Show worked answer →
Marks guide (Original, modelled on NESA criteria). 5 marks: explains the strategic role of operations in achieving cost leadership, with relevant operations strategies and an accurate contemporary example. 3-4 marks: describes cost leadership and some operations strategies with an example. 1-2 marks: general statements about cost or operations.
Model answer. The strategic role of operations management is to use the transformation process to build a long-term competitive advantage. A cost leadership strategy aims to produce goods or services at the lowest cost in the industry, so the business can charge lower prices than competitors or earn higher margins at similar prices. Operations delivers this through economies of scale, efficient supply chain management, standardised processes, automation and lean inventory.
Coles Group illustrates this. It opened an automated distribution centre at Redbank in Queensland in 2023 and another at Kemps Creek in western Sydney, officially opened in August 2024, both built with the German logistics firm Witron, and in October 2024 announced an $880 million automated ambient distribution centre at Truganina in Victoria. Automation reduces the labour cost of picking each carton and improves stock accuracy, lowering the cost per unit moved to stores. Lower operating costs support Coles' ability to compete on price with Woolworths, Aldi and others while protecting margins.
Linking the operations strategy (automation and scale) to the competitive outcome (lower unit cost, price competitiveness) is what earns the top marks.

foundation2 marksDistinguish between cost leadership and good/service differentiation.Show worked solution →
One mark for each correctly explained strategy, with the difference clear.
Cost leadership is a strategy in which a business aims to be the lowest-cost producer in its industry, competing on price or earning higher margins (1 mark). Good/service differentiation is a strategy in which a business offers a product that customers see as unique or superior (quality, design, features, service, brand), allowing it to charge a premium price (1 mark).
core4 marksDescribe the features of operations management for a business in a tertiary industry.Show worked solution →
"Describe" needs characteristics, about 1 mark each, applied to a service business.
Tertiary industries provide services, such as banking, airlines, hospitality, education and retail. Features of their operations management include:
- Intangibility and customer involvement. The customer is often part of the transformation process (high visibility), so staff behaviour, the physical environment and waiting times are part of the product.
- Services cannot be stored. Output is produced and consumed at the same time, so managing variation in demand relies on scheduling staff, booking systems and pricing, not inventory.
- Customisation. Many services are tailored to each customer, making labour skills and training central to quality.
- Quality is harder to measure. Businesses use customer satisfaction surveys, complaint rates and service standards rather than product specifications.
Example: an airline's operations include scheduling aircraft and crew, check-in, baggage handling and in-flight service, all of which customers experience directly.
exam8 marksAnalyse how the interdependence between operations and other key business functions contributes to the success of a large business. Refer to a contemporary business example.Show worked solution →
An 8-mark "analyse" needs the concept, at least two developed function pairings with cause and effect in both directions, and evaluation of the impact on business success, supported by a real example.
- Concept (1 mark)
- Interdependence means the key business functions (operations, marketing, finance, human resources) rely on each other, so decisions in one affect the others.
- Operations and marketing (about 2-3 marks)
- Coles' automated distribution centres at Redbank and Kemps Creek and its Ocado-built customer fulfilment centres for online orders at Truganina and Wetherill Park (both opened in 2024) allow it to promise online delivery and consistent product availability. Marketing can only promote these services if operations can deliver them; in turn, marketing's demand forecasts and promotions determine what operations must stock and pick.
- Operations and finance (about 2 marks)
- These facilities required very large capital investment, such as the $880 million Truganina ambient distribution centre announced in October 2024. Finance must raise and allocate the funds and assess the return, while operations must deliver the cost savings and service levels that justify the investment.
- Operations and HR (about 2 marks)
- Automation changes jobs: fewer manual picking roles, more technical maintenance roles. HR must manage redeployment, retraining and industrial relations, and operations depends on a trained workforce to run the new systems.
- Judgement (1 mark)
- Success depends on the functions working together: an operations investment that marketing cannot sell, finance cannot fund or HR cannot staff would fail, whereas coordinated decisions lower costs and improve customer service.
Marker's note: NESA's 2024 sample answer shows dependence in both directions. Apply that to every pairing.
