Case-study application is the core of IB Business Management. The assessments give you a business situation and ask you to apply concepts to it, analyse what is happening, and evaluate options. This guide explains what case-study application means, how to read a case for evidence, how to choose the right concept or tool, how to move from evidence to analysis, how to evaluate options, and how to avoid the most common mistakes.
What Does Case-Study Application Mean?
Application means using business concepts on the specific case in front of you, not reproducing them in the abstract. A question about a company's falling sales is not answered by defining marketing; it is answered by using marketing concepts to explain why sales may be falling for this company and what the implications are. Application is what turns a definition into an answer, and it is what most of the marks reward.
Read the Case for Evidence
Before you write, read the case carefully and identify the material you will use:
- Facts. What is stated about the business, its market and its situation.
- Numbers. Figures on sales, costs, capacity, market share, growth, and any trends.
- Stakeholders. Who is involved or affected: owners, employees, customers, suppliers, the community.
- Constraints. What limits the business's options: finances, capacity, regulation, time.
- Objectives. What the business is trying to achieve, and any conflicts between objectives.
- Context. The wider situation: market conditions, competition, the external environment.
Annotate the case as you read. The evidence you collect here is the raw material of your answer.
Choose the Right Business Concept or Tool
Select the concept or tool that genuinely fits the question and the case, rather than the one you know best. A question about a new product's viability may call for break-even or investment appraisal; a question about strategic position may call for SWOT or STEEPLE. The wrong tool is worse than none, because it produces analysis that does not address the question. Apply the tool to the specific business, using the evidence you collected, rather than reproducing it in the abstract.
Move From Evidence to Analysis
Strong analysis moves through a clear chain: fact, business concept, consequence, implication.
- Fact. State the relevant fact from the case.
- Business concept. Apply the concept that explains it.
- Consequence. Show what follows for the business.
- Implication. Draw the implication for the question.
Skipping the consequence is the most common reason an answer reads as a definition dump rather than analysis. The chain is what turns a list of facts into an argument.
Evaluate Options
Evaluation is the judgement layer on top of analysis. Where the question asks you to evaluate options, consider:
- Stakeholders. Who gains and who loses under each option, and how significant that is.
- Short vs long term. Whether the effects differ over time.
- Assumptions. What each option assumes, and whether those assumptions are reasonable.
- Limitations. What the analysis does not capture, and how that affects the conclusion.
- Alternatives. What other options exist, and how they compare.
Generic "pros and cons" earns little. Strong evaluation is specific to the case and the options.
Common Case-Study Mistakes
- Defining without applying. Opening with definitions and never using them on the case.
- Ignoring the evidence. Answering from memory rather than from the case.
- Tool dumping. Including many tools without applying them.
- Description rather than analysis. Saying what happens without explaining why.
- Weak evaluation. A list of pros and cons with no link to the case.
- Unsupported claims. Assertions about the business with no evidence.
- Not answering the command term. Describing when asked to evaluate.
Worked Analytical Framework
This is an original illustrative example, not an actual exam question. Suppose a fictional small bakery is considering opening a second outlet. A workable analytical framework:
- Fact. The bakery's current outlet is at capacity at peak times, and a competing chain recently opened nearby.
- Concept. Capacity, market growth and competitive position.
- Consequence. A second outlet could relieve peak congestion and capture demand the current outlet cannot serve, but it would raise fixed costs and split management attention.
- Implication. The decision depends on whether the additional demand is sustained and whether the business can finance and manage a second site.
- Evaluation. Short term, the second outlet adds cost and risk; long term, it could protect market share against the new competitor. The conclusion depends on the reliability of demand forecasts and the strength of the management team, which the case may or may not establish.
Notice how the framework moves from fact to concept to consequence to implication to evaluation, using the case throughout. Apply the same shape to any case, choosing the concept that fits.
Case-Study Analysis FAQs
How do I apply a concept? Use it on the specific business, with evidence from the case, rather than defining it in the abstract.
How many tools should I use? As many as the analysis genuinely needs, each applied to the case. A single well-used tool beats several unapplied ones.
How do I move from analysis to evaluation? Judge the options specifically: stakeholders, short vs long term, assumptions, limitations and alternatives.
Should I use the numbers in the case? Yes, where they are relevant. Use them to support a business judgement, not just to compute a figure.
What if I do not know the case? The case is provided in the exam; you are not expected to have studied it. Read it carefully and use its evidence.
