IB Business 1.4 External Environment: STEEPLE Explained with a Worked Example
STEEPLE is the sub-topic where students lose the most marks for the least reason: not because the content is hard, but because the answer stops at labelling a factor instead of explaining its effect on the specific business in the case. “Social factors affect the business” is not an analysis — it’s a category name. Examiners want to see the chain from factor, to mechanism, to consequence for that business’s decisions, costs, or revenue.
This post works through IB Business 1.4 the way I mark it: each factor defined precisely, a worked example that shows the full reasoning chain, a common mistake named specifically, and a command-term technique for turning a list into an analysis.
What STEEPLE actually stands for, precisely
STEEPLE extends the older PEST/PESTLE frameworks by separating out ethical factors as their own category. The seven factors:
- Social — demographic shifts, cultural attitudes, lifestyle trends, and changing consumer values.
- Technological — new production methods, automation, digital platforms, and the pace of innovation in an industry.
- Economic — interest rates, exchange rates, inflation, unemployment, and the business cycle.
- Environmental — climate change, resource scarcity, and the physical and regulatory pressure to operate sustainably.
- Political — government stability, trade policy, and the direction of government priorities affecting business.
- Legal — specific laws and regulations: employment law, consumer protection, competition law, data protection.
- Ethical — expectations around fair treatment of stakeholders that go beyond what law strictly requires — things a business could legally do but that would damage trust or reputation if it did.
The Political/Legal split and the Legal/Ethical split are where students lose easy marks by miscategorising. Political factors are about government direction and stability (a change in government, a new trade agreement being negotiated); legal factors are the actual laws already in force a business must comply with. Ethical factors sit outside legal compliance entirely — a business paying the legal minimum wage while its competitors pay a living wage is a legal decision with an ethical dimension, not a legal violation.
Why STEEPLE only earns marks when it’s applied
A list of seven factors with a one-line generic description each is knowledge, not analysis, and most mark schemes cap that kind of answer well below full marks. The examinable skill is: for this business, in this case, which 2–3 factors matter most, and what specifically happens as a result. STEEPLE is a scanning tool for identifying relevant factors — the actual mark-earning content is what you do with the factor once you’ve identified it.
A worked example: from factor to consequence
Suppose a case describes a mid-sized furniture manufacturer that exports to three countries, uses imported hardwood, and has recently faced a national minimum wage increase in its home market.
A weak answer: “Economic factors affect the business because wages went up, which increases costs.”
A strong answer follows the full chain — factor, mechanism, consequence, and ideally a business response:
The minimum wage increase is an economic factor that raises the manufacturer’s direct labour costs, which, given that furniture production is relatively labour-intensive, will compress gross margin unless prices rise or productivity improves. Because the business also imports hardwood, it is simultaneously exposed to economic exchange-rate risk: if the home currency weakens against the currency it pays suppliers in, input costs rise at the same time as labour costs, compounding the margin pressure rather than the two factors acting independently. A business response might be to pass part of the cost increase to customers, though this risks demand falling if competitors do not face the same wage pressure, a genuine trade-off worth naming rather than assuming price rises are cost-free.
Notice what makes this strong: it connects two factors under the same category to show a compounding effect specific to this business’s supply chain, rather than treating each factor as an isolated bullet point.
The mistake I mark down most often
Specifically: students run through all seven letters of STEEPLE for every case, regardless of relevance, producing seven thin paragraphs instead of two or three well-developed ones. A question asking you to “examine the external factors affecting [business]” is not asking for a complete STEEPLE audit — it’s asking you to identify the factors that are actually significant given the specific details in the case, and develop those in depth. Forcing in an environmental factor for a case with no environmental content, just to “cover the framework,” dilutes your answer and uses word count that should go toward developing the two or three factors that genuinely matter. Selectivity, not completeness, is what separates a strong STEEPLE answer from a weak one.
STEEPLE and internal decisions are not the same thing
A distinction worth being explicit about: STEEPLE covers factors external to the business conditions it does not control and must respond to. It’s easy to blur this boundary under exam pressure, especially with ethical factors, where a business’s own decision (how much to pay staff, whether to source ethically) can feel internal even though the pressure driving that decision, shifting consumer expectations, campaign groups, media scrutiny — is external. When a question asks for external factors, keep the analysis anchored to the pressure or condition in the environment, not the internal choice the business makes in response to it; the choice itself belongs in a different part of the answer, not the STEEPLE factor identification.
Distinguishing opportunity from threat and holding both
Many STEEPLE questions implicitly want you to assess whether a factor is a threat, an opportunity, or genuinely both depending on how the business responds. A rise in remote-work adoption (social/technological) might threaten a business selling commercial office furniture while simultaneously creating an opportunity in home-office furniture — the same underlying trend, two different consequences depending on which market segment you’re analysing. Naming only the threat, when the case gives you information suggesting an opportunity exists too, is a missed evaluation angle that “discuss” and “evaluate” questions are specifically built to reward.
This also matters for how you weigh factors against each other in an evaluative conclusion. Two businesses in the same industry can face the same external factor and reach opposite conclusions about whether it’s favourable, depending on their existing strategy, market position, and resources — a low-cost competitor entering the market is a much bigger threat to a business already competing on price than to one that has built a brand around premium service. A strong evaluation names that dependency explicitly rather than treating the factor’s impact as fixed regardless of which business is being analysed.
Exam technique: matching STEEPLE to the command term
“Identify” wants factors named, with minimal explanation, don’t over-develop when the term doesn’t ask for it. “Explain” wants the mechanism: how the factor actually changes costs, revenue, or decisions for this business, not just that it does. “Examine” and “Discuss” want you to go further still — showing both sides where relevant (opportunity and threat, short-term and long-term effect), and ideally reaching some kind of weighted conclusion about which factor matters most and why. Answering an “examine” question with “identify”-level content — a bare list of factors with no depth, caps your mark regardless of how many factors you correctly spot, because the command term sets a floor for how developed the answer needs to be, not just a ceiling.
A practice question in this style
A regional chain of gyms has seen membership growth slow for the first time in five years. At the same time, a new government health initiative offers tax incentives to employers who subsidise staff gym memberships, and a competitor has launched a lower-cost app-based fitness alternative requiring no physical location.
Examine two external factors affecting the gym chain’s membership growth, using evidence from the case to support your answer.
Work through the full chain, factor, mechanism, consequence, for each factor before checking your reasoning against the sections above; that self-check does more for your exam readiness than reading a model answer cold.
