IB Business Management HL common mistakes
IB Business Management HL · Understand the traps and how to avoid them.
Writing a generic evaluation paragraph ('it depends on the situation') instead of weighing the specific trade-off the case poses, so the judgement could apply to any business.
Candidates memorise the phrase 'it depends' as a shortcut to 'evaluate' marks and never anchor the judgement to the stimulus (size, market, cash position, timescale), so the answer reads as pre-learned and earns little credit for evaluation.
What to do instead
Before writing, state the decision in one line, then name two competing criteria drawn from the case (e.g. short-term liquidity versus long-term market share) and say which dominates and why for this firm. Close by naming the condition that would flip your judgement. Practise by rewriting any 'it depends' sentence so it contains a named stakeholder, a number, and a timescale.
Describing a PESTLE, SWOT, or stakeholder list as a set of labels rather than explaining the mechanism by which each factor changes the firm's costs, revenues, or risk.
Textbook frameworks are easy to reproduce, so under time pressure candidates dump the acronym and move on, treating the framework as the answer rather than a scaffold for analysis.
What to do instead
For every factor, force a three-step chain: factor -> effect on the business (cost, price, demand, capacity) -> consequence for the decision. Drop any factor you cannot complete the chain for. In revision, take a real news item and write the chain in one sentence for each PESTLE letter, then delete the ones that are trivial.
Calculating a ratio or variance correctly but presenting no interpretation, or interpreting it without units, comparison, or benchmark.
Candidates treat the number as the finish line and are anxious about running out of time, so they leave the figure standing alone; they also omit the base (prior year, competitor, industry average) that makes a number meaningful.
What to do instead
Adopt a fixed two-sentence pattern: 'The value is X (show working), which is above/below [benchmark] by Y, meaning [implication].' Always state units and the comparison base. In the exam, budget 30 seconds after each calculation for this sentence; it is where the analysis marks sit.
Mixing up cash flow and profit, or treating a profitable year as proof the business can pay its debts.
Both appear as 'money in minus money out' in everyday language, and candidates do not separate accruals (revenue recognised when earned, costs when incurred) from timing of receipts and payments, including depreciation and working-capital movements.
What to do instead
Keep a one-line distinction in your notes: profit measures performance over a period; cash flow measures timing and solvency. When a case mentions a profit but a cash shortage, look for the causes explicitly: credit sales, inventory build-up, capital expenditure, loan repayment, owner drawings. Practise by taking a profit figure and listing three reasons cash could still be negative.
Applying a motivation theory (Maslow, Herzberg, Taylor, Adams) by name and then asserting it 'motivates employees' without linking the theory's specific construct to a specific action in the case.
Theories are taught as content to be recalled, and candidates fear losing 'knowledge' marks, so they name-drop instead of using the theory as a lens on the stimulus.
What to do instead
Use the theory to generate a prediction, then test it against the case. Example: Herzberg predicts that a pay rise (hygiene) removes dissatisfaction but does not create motivation, so the case's retention problem will persist unless responsibility or recognition changes. Name the construct, state the predicted behaviour, apply it to the named employees, and note what the theory cannot explain here.
Recommending a structural change (delayering, matrix, centralisation) without addressing implementation: consultation, redundancy costs, resistance, skills gaps, and transition risk.
Questions ask 'should the business reorganise?' and candidates answer only the 'what' and 'why', skipping the 'how', because implementation feels like description rather than analysis.
What to do instead
Build a standing implementation checklist: cost and timing of change, who is consulted, legal and contractual constraints, effect on remaining staff morale, training needs, and how success will be measured. In any recommendation, add one sentence on sequencing (what happens first) and one on the main execution risk.
Producing a marketing mix where the four Ps are listed independently, with no consistency between them or with the chosen segment and positioning.
The four Ps are taught as a checklist, so candidates fill four slots and never test whether a premium price is matched by premium packaging, selective distribution, and promotion imagery aimed at the same segment.
What to do instead
State the target segment and positioning in one sentence first, then write each P as a consequence of it ('because we target X, price is set at Y to signal Z, distributed through...'). Add one sentence on how the Ps reinforce or contradict each other; examiners reward noticing the contradiction.
Confusing market share with market growth, or market size with sales volume, when reading or constructing a market share calculation.
The terms look interchangeable in ordinary speech, and candidates compute 'share' by dividing by the firm's own previous sales or by total market growth rather than by total market size.
What to do instead
Fix the formula in writing: market share = firm's sales / total market sales x 100, with both in the same units and the same period. Before calculating, write down what each figure in the case actually is. If given growth rates, note that a firm can grow while losing share, and say so explicitly.
Answering an operations question on capacity, inventory, or quality without quantifying the trade-off (stockholding cost versus stockout cost, unit cost versus flexibility).
Operations topics attract descriptive answers about 'lean' and 'quality', and candidates avoid numbers because the arithmetic looks optional; without figures the analysis stays at the level of assertion.
What to do instead
For any operations recommendation, attach at least one number from the case and compute the consequence: e.g. holding cost per unit x buffer units versus expected lost contribution per stockout x probability. If the case gives no data, state the assumption explicitly and show how the decision changes if it is wrong.
Ignoring the command term: writing a 'discuss' answer as a list of points, or a 'justify' answer as a balanced two-sided essay with no decision.
Candidates read the topic and start writing content, and under time pressure the command term is skimmed; many also believe balance is always rewarded, even when the verb demands a recommendation.
What to do instead
Circle the command term and the directive words ('using the case', 'two stakeholders') before planning. Map verbs to output: 'explain' = mechanism, 'analyse' = cause and effect chain, 'discuss' = both sides plus a judgement, 'justify' = recommendation with reasons and rebuttal of the alternative, 'evaluate' = weighed judgement with conditions. Spend 60 seconds converting the verb into a one-line plan and check the final paragraph matches it.
