WJEC A-Level Business Business Analysis and Strategy (A2 Unit 3): a deep dive on data, elasticity, forecasting, ratios, strategy, growth and investment appraisal

What Business Analysis and Strategy actually demands

Business Analysis and Strategy is the first A2 unit of WJEC A-Level Business, and it builds on the AS theory with sharper analytical and quantitative content. You analyse data and elasticity, forecast sales, interpret financial ratios, apply strategic models, weigh methods of growth, and use formal decision-making and investment-appraisal techniques. The paper is data-response plus structured questions, so examiners test accurate calculation, application to a business context, and balanced evaluation that recognises the limits of each model.

This guide ties together the eight dot-point pages for the unit. Each has its own page with worked exam questions and cross-links; this overview shows how they connect and where the marks lie.

Data and market analysis (including elasticity)

Data analysis turns raw figures into insight. Price elasticity of demand (PED = % change in quantity / % change in price) shows whether demand is inelastic (raise price to lift revenue) or elastic (cut price to lift revenue). Income elasticity (YED) is positive for normal goods, strongly positive for luxuries and negative for inferior goods, helping firms plan for the economic cycle.

Sales forecasting and time series

Time-series analysis separates sales data into trend, seasonal, cyclical and random variation. A moving average smooths the data to reveal the trend. Extrapolation projects the trend forward - quick and cheap, but it assumes the past continues, so it is unreliable in a changing market and the further ahead it reaches.

Financial analysis: budgets and ratios

Budgets set targets and variance analysis (favourable or adverse) controls performance. Ratio analysis interprets the income statement and balance sheet: profitability (margins, ROCE), liquidity (current ratio, acid-test) and efficiency. Ratios are most useful as comparisons over time and against rivals but rest on historic data and ignore qualitative factors.

Business objectives and strategy

Aims and SMART objectives set direction. SWOT audits internal strengths and weaknesses and external opportunities and threats. The Ansoff Matrix maps growth by product and market (penetration, product development, market development, diversification, in rising risk). Porter's Five Forces judge a market's attractiveness through entrants, substitutes, buyer and supplier power and rivalry.

Growth and methods of expansion

Organic growth expands from within (slower, lower-risk, keeps control); external growth uses mergers and takeovers (faster, costlier, integration risk). Franchising scales a proven format using franchisees' capital, outsourcing contracts activities to specialists, and rationalisation cuts capacity to raise efficiency. Each is a trade-off of speed, cost, risk and control.

Decision-making models

Decision trees map options, probabilities and outcomes; the firm picks the highest expected value net of cost. Critical path analysis schedules a project and finds the critical path (the longest, zero-float sequence) that sets the minimum time. Cost-benefit analysis weighs all costs and benefits, including social ones. All rely on estimated data and ignore qualitative factors.

Investment appraisal

Payback is the time to recover the cost (simple, liquidity-focused, but ignores later cash flows). ARR = (average annual profit / initial investment) x 100. NPV discounts future cash flows to the present and subtracts the cost; a positive NPV is worthwhile and it captures the time value of money. The methods are best used together.

Special order decisions

A special order at a below-normal price is judged by contribution (price minus variable cost). With spare capacity, fixed costs are already covered, so a positive contribution adds to profit and the order is worth accepting - subject to qualitative factors, above all the risk of undercutting normal prices.

How Business Analysis and Strategy is examined

A typical WJEC profile for Unit 3:

• Quantitative calculations. Elasticity, ratios, moving averages, expected value, payback, ARR, NPV and contribution, with method marks.
• Data-response analysis. Apply a model or calculation to a stimulus about a business.
• Strategic application. Use SWOT, Ansoff or Porter to justify a strategy.
• Evaluation. Weigh the limitations of a model or method and reach a supported judgement.

Check your knowledge

A mix of calculation, model and evaluation questions covering the whole unit. Attempt them under timed conditions, then check against the solutions.

1. A price rises 8% and demand falls 16%. Calculate the PED and state whether demand is elastic or inelastic. (3 marks)
2. Sales over four quarters were 20, 40, 60 and 80 (£000). Calculate the four-quarter moving average. (2 marks)
3. A firm has current assets of £90,000 and current liabilities of £45,000. Calculate the current ratio. (2 marks)
4. Explain why diversification is the highest-risk Ansoff strategy. (3 marks)
5. Distinguish between organic and external growth. (3 marks)
6. A decision has a 70% chance of a £40,000 gain and a 30% chance of a £10,000 loss. Calculate the expected value. (3 marks)
7. A machine costs £30,000 and earns £10,000 a year. Calculate its payback period. (2 marks)
8. A special order of 400 units is offered at £13 each; variable cost is £8 and there is spare capacity. Calculate the total contribution. (2 marks)
