How the four business functions support a common goal

1. A business combines four connected functions

Business Studies groups a business's work into operations management, human resource management (HRM), marketing management and financial management. Operations turns resources into a product or service. HRM obtains and develops the people needed to do that work. Marketing researches customers and communicates an offer. Finance records and analyses the money needed to plan and judge performance. These are useful categories for analysing a case; in a small business, one person may carry out several functions.

The functions depend on one another. If a Tasmanian berry producer plans to add a frozen product, operations must check processing capacity and packaging, HRM must plan any extra skills or shifts, marketing must test which customers value the product, and finance must compare equipment costs with likely revenue and cash timing. A recommendation that considers only one function can create a problem elsewhere. A discount may lift demand but overload production; new equipment may increase capacity but leave the business without cash to buy seasonal fruit.

Use the four-function model to diagnose a real constraint. If a Tasmanian berry business wins a supermarket order for frozen packs, operations should confirm grading, freezing and packing capacity; HRM should check shift coverage and food-handling skills; marketing should confirm the order specification and delivery promise; finance should price packaging, labour, energy and freight. The order is attractive only if these plans fit together.

Students often confuse a business function with a department. A department is a formal organisational unit with its own staff and manager, which only appears once a business is large enough to separate roles. A function exists in every business regardless of size: a sole trader guiding kayak tours on the Tasman Peninsula still plans routes and safety checks (operations), rosters casual guides in the school-holiday peak (HRM), posts to a booking platform and answers enquiries (marketing), and tracks fuel, insurance and permit costs against tour revenue (finance) — without a single department existing. In an exam response, naming the function correctly matters more than assuming it requires a named team.

2. Goals describe what the business is trying to achieve

Goals and objectives give managers a direction for decisions. The course identifies goals such as profit, personal efficiency, effectiveness and social responsibility. A business may also set objectives about growth or market share. Use the wording in the question and the scenario: an objective should be specific enough to guide a decision. “Improve customer service” is broad; “reduce average response time while maintaining the current complaint rate” gives managers something more measurable to monitor.

Efficiency concerns the relationship between inputs and outputs: using fewer resources for a given output, or producing more from the same resource base. Effectiveness concerns whether the intended result is achieved. A firm can be efficient at producing an item customers do not want, so efficiency alone does not prove success. Profit is important to a commercially operated business, but a decision can also affect workers, customers, the community and the environment. Explain which goals matter in the stated case rather than assuming all businesses have an identical priority.

Objectives help distinguish a desirable outcome from an activity. “Buy a freezer” is an action; “reduce quality losses during the peak harvest while earning a positive return” is an objective that can guide the purchase decision. A manager can measure spoilage, saleable kilograms and incremental contribution against a baseline. The objective should have a realistic time period and should not reward one function for shifting a cost to another.

A frequent confusion is treating “goal” and “objective” as identical. A goal is the broad direction, such as profitability or growth; an objective is the specific, measurable target that operationalises that goal within a stated timeframe. For a fictional bakery, Tamar Valley Sourdough, the goal might be “build a sustainable local business.” A supporting objective could be “increase weekday retail sales from $3,200 to $4,000 per week within two school terms without extending opening hours.” Examiners reward the objective's specificity — a figure, a timeframe and a constraint — over a restated goal. When a scenario gives numbers, use them: comparing $3,200 against $4,000 lets you calculate a required 25 per cent increase and discuss whether existing staffing and oven capacity make it realistic.

3. Trace the effect across functions before recommending a change

When a case proposes a change, build a short cause-and-effect chain. First identify the business goal. Then state the function most directly involved and the evidence that signals a problem or opportunity. Next consider at least one other function that will be affected. For example, a home-delivery expansion may improve customer access through marketing, require new operational routes, change driver recruitment and training, and add vehicle costs to the cash budget. A well-supported recommendation explains both the likely benefit and the resource or risk that accompanies it.

Keep the distinction between the function and the action clear. “Marketing” is not a strategy by itself; a strategy might be targeted online promotion to an identified customer segment. “Finance” is not a solution; financing an asset through debt or owner equity has different cash, control and risk implications. In a written response, name the action, connect it to a goal and explain how evidence would show whether it worked.

For a linked decision, identify the primary cause before prescribing a function-level response. A late delivery might arise from inadequate picking forecasts, not weak promotion. More advertising could worsen the delay. Compare order records, harvest estimates and dispatch times to locate the bottleneck, then select coordinated changes with named owners and review dates.

Consider a worked chain for Tamar Valley Sourdough considering home delivery within a 15-kilometre radius. Marketing evidence: a customer survey shows 40 per cent of enquiries ask about delivery. Operations consequence: existing ovens and packing bench can support the extra volume, but delivery requires insulated bags and a delivery run scheduled around baking finish times. HRM consequence: the business needs a casual driver for two mornings a week, requiring a police check and induction on food-handling during transport. Finance consequence: if delivery adds $180 per week in vehicle and packaging cost and expected extra sales are $260 per week, the net contribution before wages is $80 — a marginal case that depends heavily on whether the survey figure converts into actual orders. This is the kind of quantified, function-by-function reasoning that earns higher marks than describing the idea in general terms.

4. Exam application

A short response can earn clear business marks by defining the relevant function or goal, applying it to the scenario and explaining the consequence. Avoid writing four separate textbook definitions when the task asks how functions work together. Use the case's product, customers, staff, resources or objective. If the task asks for a recommendation, close by stating why the action is preferable under the supplied conditions and what the business should monitor.

Check yourself: A small manufacturer is receiving more online orders than it can dispatch. Identify two functions involved, propose one action for each, and explain how the actions support the same business objective. A complete answer separates the marketing source of demand from the operations capacity constraint and links each response to timely fulfilment or customer satisfaction.

In an exam response, tie every function to a fact. For example, “HRM should roster a trained evening packer because the case shows orders arrive after the current shift” is applied; “HRM manages employees” is only a definition. Explain how the action supports the objective and mention a cost or constraint where relevant. Do not claim a revenue increase without evidence of demand.

Consider how markers distinguish a partial answer from a complete one. For the online-order scenario, a two-mark response might state: “Operations should extend the packing shift because the case shows orders now arrive until 9 pm, after the current 5 pm cutoff, so unpacked orders accumulate overnight and delay next-day dispatch.” This earns marks because it names the function, cites the specific evidence (9 pm arrivals, 5 pm cutoff) and states the consequence (accumulation, delayed dispatch). A response that only writes “operations should work more efficiently” restates the function without using the case, and typically receives no more than one mark even if the general idea is correct. Where a question is worth more marks, extend the same technique to a second function and show how the two actions reinforce, rather than duplicate, each other.

5. Work a decision through the system

Use a decision map when the case gives several linked problems. Start with the objective and identify the function closest to the immediate issue, then follow consequences into the other functions. If a business wants faster delivery, operations may change scheduling, human resources may need new skills or shifts, marketing must communicate a promise the process can meet, and finance must test the cost against expected sales or savings.

Separate a direct effect from a possible later effect. A process improvement could reduce waiting time directly; customer loyalty might improve later, but only if reliability and service also meet expectations. This distinction helps a recommendation stay evidence-based instead of claiming every benefit is guaranteed.

A decision map is especially useful when the business has a seasonal product. Forecast demand and available fruit first; operations tests daily throughput and storage; HRM plans temporary labour and induction; marketing separates confirmed retailer orders from speculative interest; finance schedules supplier payments and customer receipts. If any forecast changes, managers can revisit the affected functions before making a larger commitment.

A useful check is to separate what happens in week one from what happens over a season. For a fictional business, Bruny Bay Oyster Co, faster order processing (a direct, immediate operations change) might cut average dispatch time from three days to one day within the first week. Improved customer loyalty (an indirect, longer-term effect) can only be assessed after several months of repeat-order data, and depends on whether quality and reliability also hold up under the faster pace. A student who writes “faster dispatch will increase loyalty” without this distinction is asserting an outcome the case has not yet demonstrated. A stronger response states the immediate, evidenced effect first, then names the longer-term effect as a hypothesis to be tested against future order data, not a certainty.

6. Compare options with a shared measure

When comparing two proposals, apply the same objective and time period to both. A short-term cost reduction may weaken quality, while an investment may raise current expenses and improve capacity over time. Identify which function bears the cost and which may receive the benefit. If those effects are split, explain how managers could coordinate the decision.

In a response, state the evidence, the link between functions and the expected result. A useful check is to ask whether the proposal remains feasible if one assumption changes, such as demand being lower than forecast. If the business cannot deliver the promised result under that case, revise the proposal or name the risk that management must monitor.

Use common measures to compare options fairly. If one proposal is evaluated over a month and another over a full harvest season, their costs and benefits are not comparable. A useful set might include contribution per kilogram, spoilage rate, on-time orders and cash required before receipts. State which objective matters most and what trade-off the owner accepts, then define a threshold for continuing or stopping the trial.

For the berry example, make the evaluation decision explicit: compare a staged production run with the full-season commitment using the same measures and period. A staged run limits working-capital exposure while generating actual labour, spoilage and reorder data. It may have a higher unit cost, so managers should calculate whether the information gained is worth that cost before scaling.

A worked comparison makes the principle concrete. Suppose Bruny Bay Oyster Co compares a staged three-week trial of a new grading machine against committing to it for the full six-month season, using contribution per dozen as the shared measure. The trial processes 200 dozen at $1.40 contribution each ($280 total), less a $150 hire fee, netting $130. The full-season commitment processes an estimated 4,000 dozen at the same margin, but risks a $3,200 purchase cost before sales are confirmed. Using the same measure over comparable evidence shows the trial yields lower total profit but far less downside if oyster volumes fall short, which is the trade-off a recommendation should state rather than declaring one option simply “better.”
