200 essay vocabulary words and examples

Business decisions, performance and strategy

  1. revenue — income from sales before deducting costs in the usual trading context. higher sales volume can increase revenue.

Exam requirements and worked examples

What Paper 1 and Paper 4 require

AS Paper 1 is worth 40 marks. Section A has four compulsory five-mark questions. In Section B, select one of two 20-mark essays. The chosen essay has two parts, and the second part should show evaluation. Check the question’s own marks and command words.

A Level Paper 4 is worth 40 marks. Both case-based questions are compulsory. Use details from the business to show application. Analysis explains what changes and why. Evaluation uses the business’s objectives, risks and constraints to reach a supported conclusion.

Official specifications and case-study sources

Worked strategy example on buying equipment

Original practice case. A small food producer is considering faster packing equipment. It often has unfilled orders during a busy season. Several buyers pay after delivery. The new machine requires an upfront payment and training.

Faster equipment could raise throughput if packing is the constraint. In that case, the producer might fill more orders and generate more contribution to fixed costs. But a higher sales figure would not immediately solve a cash problem if buyers pay later. The machine and training require cash before some of the extra sales turn into receipts. The timing of flows matters alongside the size of the potential profit.

A recommendation could support the purchase if packing is confirmed as the bottleneck and cash forecasts show the business can meet obligations during installation. If supply of ingredients or demand is the real constraint, the same equipment may add capacity the producer cannot use. Compare a staged alternative before deciding.

Turn a case detail into analysis

Take the detail that buyers pay after delivery. It is relevant because the firm pays some costs before receiving cash. That relationship can change whether the project is financeable, even when the expected contribution is positive. The detail becomes application when it changes your reasoning, rather than when you copy it into a sentence.

To compare strategies, name the criterion. Capacity expansion can improve throughput. Better scheduling could cost less and improve the use of existing equipment. Decide which better fits the cause of missed orders. A finance argument and an operations argument can support the same conclusion only when you explain how they interact.

How to fence a Business term

1. Base. Packing is the bottleneck. 2. Detail. Packing limits the number of orders the producer can dispatch. 3. Tone. Faster packing could improve throughput if the rest of the process can keep up. 4. Logic. Because extra capacity adds value only when orders can be filled and sold, check demand and supply before recommending investment. 5. Transfer. More customer-service staff may have little effect if authorisation is the step delaying decisions.

Distinguish contribution from profit. Contribution is revenue less variable costs. Profit depends on which costs and income are included in the specified measure. Use the exact figure requested, then explain what it means for the case decision.

Practice and frequently asked questions

Do I answer both Paper 4 questions? Yes. Are the AS essays in Section B of Paper 1? Yes, choose one and answer its parts. What makes evaluation case-based? It gives a judgement shaped by specific objectives, evidence or limits in that business.

Try a practice question on outsourcing. List one reason it could reduce costs and one reason it could reduce control over quality or timing. Link each to a case detail. Then state which condition would make outsourcing preferable to improving the current operation.

Practice workshops

Diagnose the constraint before recommending a strategy

Use the case to identify which stage prevents the business from meeting its objective. If orders are late because ingredients arrive slowly, faster packing may not help. If packing is the slowest stage and demand is strong, extra capacity could matter. State what evidence would distinguish the two explanations before deciding.

Build a case-based chain of analysis

Pick one detail, such as customers paying after delivery. Explain the immediate effect and the further consequence. The firm may record sales before it receives cash, while still having to pay staff and suppliers. That gap matters when assessing a purchase. The application becomes visible when the case detail changes your conclusion.

Distinguish profitable growth from liquidity

An investment may increase expected profit over time while putting pressure on short-term cash. Write one sentence describing each effect. Then name a condition that would make the investment financeable. If credit terms or timing are important, explain which payments arrive first and which costs have to be met in the meantime.

Evaluate implementation rather than listing tools

A strategic framework can identify opportunities and risks. It does not decide whether the firm can execute a choice. Explain who will install, train or monitor the proposed change. Then judge what happens if the plan takes longer than expected. This links the framework to practical requirements in the case.

Compare a staged alternative

Instead of immediately buying equipment, a firm might test extra shifts, hire capacity or improve scheduling. Compare the alternatives by cost, speed, control and reversibility. Select the criterion that matters most to the stated objective. If the case says orders are seasonal, explain why timing changes the recommendation.

Make a calculation support a decision

If a practice case gives selling price, variable cost and fixed cost, calculate the contribution and break-even output using the relevant figures. Then compare the result with realistic demand. A calculation can show the output required under assumptions. Explain what changes if price, cost or sales volume differs.

Use a marketing concept in context

For segmentation, identify a specific group and why its needs or behaviour differ. Explain how that difference could justify a change in the offer or promotion. Then test whether the firm has the resources to reach the group. The concept should help evaluate a decision, rather than merely naming an approach.

Apply a human resources point

A change in equipment may require staff training, different roles or a revised shift pattern. Choose one implication and explain how it could affect quality, morale or throughput. Then consider how the timing and availability of staff affect the result. Give the manager a criterion for deciding whether the change is practical.

Answer both questions under timed conditions

When using Paper 4 as a mock, plan each compulsory answer separately. Identify the decision and supporting evidence for the first, then do the same for the second. Avoid repeating a paragraph unless the reasoning truly fits the different question. Leave time to write a judgement for both.

Check whether the recommendation could change

State the condition that would reverse your recommendation. In the equipment case, weak demand or a shortage of inputs could make the investment less useful. If no evidence could change your decision, look again for an assumption you are treating as certain. A strong conclusion names the most important condition.

Read the draft as the decision-maker

Underline the action you recommend and the detail in the case that most strongly supports it. Identify one risk, who would manage it and what the firm should monitor. If the recommendation could fit any business, add the specific objective or constraint that makes it appropriate here.
