Open a point below for its explanation and revision guidance.
a) Objectives of growth: to achieve economies of scale (internal and external); increased market power over customers and suppliers; increased market share and brand recognition; increased profitability
Growth objectives are the reasons a board signs off on getting bigger. Lower unit costs come from internal sources such as technical, purchasing, managerial, financial and risk-bearing scale, and from external sources such as a skilled labour pool clustered around an industry; unit cost is total cost divided by output, so the test is whether cost per unit actually falls. Buying power means squeezing supplier prices, while selling power means setting price rather than taking it. A bigger share and a better-known brand raise barriers to entry. The judgement is that scale is a means and not an end: growth adds value only if profitability, such as return on capital employed, rises.
b) Problems arising from growth: diseconomies of scale; internal communication; overtrading
Past the minimum efficient scale, average cost per unit rises again, and the causes are human rather than technical: coordination between more sites, a longer chain of command that distorts messages, and workers who feel anonymous, which is exactly the loss of recognition Herzberg and the Mayo studies warn about. Communication failures show up as duplicated work, slow decisions and inconsistent service. Cash is the third problem. A firm that expands sales faster than its working capital allows can be profitable on paper and still unable to pay suppliers, because inventory and receivables absorb cash before customers pay. Watch the current ratio, current assets divided by current liabilities, and the acid test, current assets less inventory divided by current liabilities. None of these is inevitable: decentralisation, divisional structure and an overdraft facility each buy time.
Your focus
- Calculate and interpret changes in unit costs to identify internal and external economies of scale.
- Analyse how growth objectives like increased market share and brand recognition impact market power.
- Evaluate the relationship between business growth and increased profitability.

Growth exam tips
Marking Points
- Name the specific economy of scale, not just the phrase: bulk purchasing cutting materials cost per unit, or spreading the cost of one distribution centre over more deliveries, applied to the business in the extract.
- Separate internal economies, which come from the firm expanding, from external economies, which come from the whole industry expanding around it, and show which one the case evidence supports.
- Quantify the objective from the data: market share in percentage terms, unit cost before and after, or return on capital employed as operating profit divided by capital employed times one hundred.
- Convert market power into a decision: greater monopsony power over suppliers protects the gross margin, while greater power over customers supports a price rise without losing volume.
- Define the problem in a clause and then explain the mechanism: diseconomies raise average cost per unit because coordination and monitoring absorb management time faster than output grows.
- Link communication breakdown to a motivation theory, such as Herzberg on recognition or Mayo on group belonging, and say what it costs the business in labour turnover or quality.
- Explain overtrading as a liquidity problem rather than a profit problem, using the current ratio and the acid test ratio, and say what a value below one implies for paying suppliers.
- Use the extract to show the problem is real for this firm, for example a rising number of sites, a falling operating margin or a cash balance shrinking while revenue grows.
- Judge how far the problem can be managed, naming a specific remedy such as decentralising decisions to regional managers or negotiating longer supplier credit.
Examiner Tips
- 💡This topic often appears in an extended response on whether a named firm should pursue growth, requiring an evaluation of one objective against the cost of achieving it.
- 💡Use the financial data supplied in the extract rather than inventing figures; a calculated share, margin or return strongly supports the argument.
- 💡A strong conclusion says which objective dominates and on what evidence, and names the condition that would change the answer, such as the state of the market or the firm's current gearing.
- 💡Overtrading questions usually come with a cash flow forecast or a balance sheet extract, so calculate the liquidity ratio before you write the argument rather than after.
- 💡This content pairs naturally with sources of finance, so a strong answer names the finance that would solve the cash problem and says what it costs in interest or in gearing.
- 💡In a twenty mark response, devote a paragraph to the counter argument that growth also brings scale benefits, then decide which dominates for this business over the stated time frame.
Common Mistakes
- Saying economies of scale mean total costs fall. Total costs rise as output rises; it is average cost per unit that falls, and answers that miss this lack accurate analysis.
- Treating external economies of scale as anything happening outside the factory gates. They arise from growth of the industry as a whole, such as a local supply cluster or a college running the relevant apprenticeships.
- Assuming a larger market share automatically means higher profit, when share bought through price cutting can raise revenue while destroying the contribution per unit.
- Confusing diseconomies of scale with a simple rise in total costs, when the point is that average cost per unit turns upward past the minimum efficient scale.
- Describing overtrading as making a loss. An overtrading business is usually growing and profitable; what it lacks is cash, and that distinction is where the marks are.
- Vague statements that communication gets worse, with no named consequence such as duplicated stock orders, missed delivery promises or inconsistent customer service.
- Treating diseconomies as automatic, which removes the evaluation; a well structured firm can grow for years without them appearing.
