Key Concept

Five marks. The concept must run through everything - not just the introduction.

Criterion A (Key Concept) is worth 5 of your 25 marks - the joint highest criterion. It rewards work where the key concept genuinely shapes the research and is woven meaningfully through the analysis and conclusion. It punishes work where the concept appears once in the introduction and is then forgotten.

You have four concepts to choose from. Pick one - not two, not a blend. One concept, used deeply and consistently.

Label vs. engine. The difference between a 2 and a 5 on this criterion is not how many times you write the concept word. At a 2, the concept is a label: it is attached to the work but not driving it. At a 5, the concept is the engine: if someone deleted every mention of it, the whole argument would fall apart. That is what you are aiming for.

The four concepts

C

Change

Transformation in a business's strategy, structure, market, product, or environment. Use this concept when your RQ centres on a significant shift: a pivot in direction, a response to disruption, a restructuring. Ask not just what changed, but why, how it was managed, and whether it achieved what was intended.

C

Creativity

The development and application of new ideas, products, processes, or business models. Use this when your RQ is about innovation, design, a new approach to an old problem, or how a business has found an unconventional solution. Creativity in BM is broader than invention - it includes creative strategy and new ways of organising.

E

Ethics

The principles and values that guide business decisions. Use this when your RQ involves a tension between profit and responsibility: environmental impact, labour practices, supply chain fairness, data privacy, or marketing to vulnerable groups. A strong ethics IA does not just judge: it analyses the trade-offs.

S

Sustainability

The ability of a business to operate in a way that meets present needs without compromising future capacity - environmental, social, or economic. Use this when your RQ explores long-term viability, triple bottom line performance, circular economy approaches, or balancing profit with planet and people.

How to choose your concept

The most common mistake is picking a company, writing about it, and then trying to attach a concept afterwards. Instead, start by asking: what is the conceptual question here? "Is this company's practice ethical?" "Is this change worth making?" "Is this strategy sustainable?" That question becomes your RQ, and the concept is already embedded in it.

Once you have a conceptual question, check it:

If the answer to all three is yes, you have the right concept. If not, try another.

Put the concept word in your RQ. This is not required, but examiner reports consistently note that strong IAs do this. If your RQ contains the word "ethical" or "sustainable" or "change," you will naturally return to it throughout your writing. If the concept is not in your RQ, you have to remember to bring it in, and most students forget.

How to use the concept throughout the IA

The concept should appear in at least four places, each time adding something:

1

Introduction: define it

Give a clear, precise definition of the concept as it applies to your business context. Do not just quote the IB glossary - explain what it means for your specific case.

2

Analysis: apply it

Use the concept as a lens for interpreting what your tools show. If your concept is sustainability, your Triple Bottom Line analysis should examine how the business balances people, planet, and profit. If it is change, your Ansoff Matrix or Lewin's Change Model should track how the business shifted and what drove it.

Choose tools that connect to the concept. When deciding between frameworks, ask: will this tool produce findings that connect to my concept? If your concept is ethics and you are choosing between a stakeholder analysis and a generic SWOT, the stakeholder analysis will naturally generate ethical findings (who benefits, who is harmed, is that fair?) while the SWOT probably will not. Your tool selection is a chance to build the concept into your analysis automatically.

End each section by connecting back to the concept. After analysing revenue trends, ask: what does this mean for sustainability? After a force field analysis, ask: what does this tell us about whether this change should happen? This does not need to be long. One or two sentences at the end of each section is enough to keep the thread alive.

3

Evaluation: test it

Use the concept to structure your evaluation. Has the business genuinely embodied the concept, or only superficially? What are the limits of the concept in this context? Where does it create tensions or trade-offs?

4

Conclusion: reflect on it

Your conclusion should return to the concept and say something non-obvious about it. Not just "therefore, sustainability is important" - but what this specific case tells us about how this concept works in practice.

Put it on your title page. The chosen key concept must be explicitly stated on the title page. This is a formal requirement - without it, you cannot access the full 5 marks available for Criterion A.
The concept is the thread, not the subject. Your subject is the business and its decision. The concept is the intellectual framework you bring to bear on it. A strong concept integration makes the IA feel coherent and purposeful: everything connects to a central idea.
Practical test. After you finish a draft, search for your concept word (and its synonyms) in the document. Note which sections it appears in. If there are sections where it is absent, those are the sections pulling your A mark down. Go back and ask: what does my concept have to say about what I am discussing here?
