在WJEC商务课程中，掌握案例分析是将理论知识转化为高分的关键。本文将通过一个完整案例，手把手教你如何分析企业、运用核心概念并写出高分答案。你将全程跟踪一家名为“柠檬乐”的虚构企业，并使用真实的考试技巧进行分析。
1. What is a Business Case Study? | 什么是商务案例分析？
A business case study is a detailed description of a company facing a particular situation or problem. It could be about a start-up, a multinational, or even a school enterprise. In your exam, you will read a short case and then answer questions that test your ability to apply business knowledge — not just repeat it.
商务案例分析是对面临特定情况或问题的企业进行的详细描述。它可能涉及初创公司、跨国公司，甚至学校企业。在考试中，你会阅读一个简短的案例，然后回答问题，这些问题考查的是你应用商务知识的能力，而不仅仅是复述知识。
Case studies often include information about the owner, products, costs, customers, and competition. Your job is to spot the important business ideas hiding in that information and then explain them using the correct terminology. That is exactly what we will practise here.
案例材料通常包含企业主、产品、成本、顾客和竞争对手等信息。你的任务是从这些信息中发现隐藏的重要商业概念，并用正确的术语加以解释。这正是我们接下来要练习的内容。
2. Introducing Our Case Study Business: Lemonade Delight | 引入案例企业：柠檬乐
Lemonade Delight is a small business owned and run by 13-year-old Emily. She started selling fresh lemonade from a stall in her local park every Saturday during the summer holidays. Each cup of lemonade is priced at £1.50, and the ingredients (lemons, sugar, water) cost around £0.30 per cup. Emily pays a weekly stall fee of £5.00 to the local council. Her two friends, Jake and Mia, help her serve customers but do not get paid; they simply enjoy being part of a team and learning about business.
柠檬乐是一家小企业，由13岁的艾米莉拥有并经营。她在暑假期间每周六在当地公园摆摊售卖鲜榨柠檬水。每杯柠檬水售价1.50英镑，原料成本（柠檬、糖、水）约为每杯0.30英镑。艾米莉每周需向地方议会支付5.00英镑的摊位费。她的两个朋友杰克和米娅帮忙招待顾客，但不领取工资；他们只是享受参与团队和了解商业的过程。
Emily has one main competitor: a small cafe at the park entrance selling bottled lemonade for £1.80. She wants to stand out by offering a homemade product with a friendly personal touch. Her immediate goal is to earn enough profit to buy a proper lemonade machine and eventually sell at two locations.
艾米莉有一个主要竞争对手：公园入口处的一家小咖啡馆，出售瓶装柠檬水，每杯1.80英镑。她希望通过提供自制产品和亲切的个人服务来脱颖而出。她的近期目标是赚取足够利润购买一台像样的柠檬水机，并最终在两地销售。
3. Setting Business Objectives | 设定商业目标
Every business needs objectives — the targets it sets to measure success. Common objectives for a start-up like Lemonade Delight include survival (covering costs and making a small profit), profit maximisation, and growth. Emily’s primary objective is profitability: she wants her revenue to be significantly higher than her costs so she can reinvest the surplus into better equipment.
每家企业都需要目标——即衡量成功的指标。像柠檬乐这样的初创企业的常见目标包括生存（覆盖成本并获得小额利润）、利润最大化和增长。艾米莉的首要目标是盈利：她希望收入远高于成本，以便将盈余再投资于更好的设备。
A secondary objective is to build a brand that customers trust. By using fresh ingredients and a cheerful service, Emily hopes her regulars will choose her over the cafe even if her price is eventually raised. Objectives can be expressed financially, like ‘achieve a weekly profit of at least £30’, or non-financially, like ‘achieve 100% customer satisfaction’.
第二个目标是建立一个顾客信赖的品牌。通过使用新鲜食材和热情服务，艾米莉希望顾客们即使在她涨价后也会选择她而非咖啡馆。目标可以用财务指标表达，比如“实现每周至少30英镑的利润”，也可以用非财务指标表达，比如“实现100%的顾客满意度”。
4. Identifying Key Stakeholders | 识别关键利益相关者
Stakeholders are individuals or groups who have an interest in the activities and success of a business. For Lemonade Delight, the main internal stakeholder is Emily, the owner. She is directly affected by the profit or loss and makes all the key decisions. Her two helpers, Jake and Mia, are also internal stakeholders because they contribute their time and effort and may expect future rewards or a share of recognition.
利益相关者是对企业的活动与成败有利益关系的个人或群体。对于柠檬乐来说，主要的内部利益相关者是所有者艾米莉。她直接受到盈亏的影响，并做出所有关键决策。她的两个帮手杰克和米娅也是内部利益相关者，因为他们贡献了时间和精力，并可能期待未来的回报或认可。
External stakeholders include customers, who want a tasty and affordable drink; the supplier of lemons and sugar, who depends on repeat orders; and the local council, which collects the stall fee and expects the pitch to be kept tidy. Sometimes stakeholder interests conflict: customers may want lower prices, but Emily wants higher profits to grow. Understanding these relationships helps a business make balanced decisions.
外部利益相关者包括顾客，他们想要美味且价格实惠的饮品；柠檬和糖的供应商，他们依赖反复的订单；以及地方议会，他们收取摊位费并希望摊位保持整洁。有时利益相关者之间会发生利益冲突：顾客希望价格更低，而艾米莉则希望获得更高的利润以促进增长。理解这些关系有助于企业做出平衡的决策。
5. SWOT Analysis: A Simple Tool | SWOT分析：一个简单的工具
SWOT is a framework that helps businesses analyse their Strengths, Weaknesses, Opportunities and Threats. Strengths and Weaknesses are internal factors, while Opportunities and Threats come from the outside environment. Let us apply this tool to Lemonade Delight.
SWOT是一种帮助企业分析其优势、劣势、机会和威胁的框架。优势和劣势是内部因素，而机会和威胁则来自外部环境。让我们将这个工具应用到柠檬乐上。
Strengths: Low material cost per cup (£0.30), strong personal service, fresh homemade taste, no wage bill for helpers.
优势：每杯材料成本低（0.30英镑），强有力的个人服务，新鲜自制口味，无需支付帮手工资。
Weaknesses: Only operates one day per week, no brand recognition yet, limited working capital for expansion, reliant on good weather for outdoor sales.
劣势：每周仅营业一天，尚无品牌知名度，用于扩张的营运资金有限，户外销售依赖好天气。
Opportunities: Growing demand for healthy refreshments, possibility of selling at local events, adding new flavours, using social media for free promotion.
机会：对健康清凉饮品的需求日益增长，有可能在当地活动中销售，增加新口味，利用社交媒体免费推广。
Threats: Competition from the park cafe, changeable summer weather, possible increase in ingredient costs, new regulations on street trading.
威胁：公园咖啡馆的竞争，多变的夏季天气，可能的原料成本上涨，关于街头贸易的新法规。
6. The Marketing Mix (4Ps) in Action | 营销组合（4P）实战
The marketing mix describes the four key elements a business can control to influence customers: Product, Price, Place and Promotion. For Emily, getting the mix right is essential to stand out from the cafe competitor.
营销组合描述了企业可以控制以影响顾客的四个关键要素：产品、价格、地点和促销。对艾米莉来说，正确的组合对于从咖啡馆的竞争中脱颖而出至关重要。
Product: Freshly squeezed lemonade, served with a slice of lemon and a smile. Emily can add varieties like strawberry or mint lemonade to attract different tastes.
产品：鲜榨柠檬水，配上一片柠檬和微笑服务。艾米莉可以增加草莓或薄荷柠檬水等品种以吸引不同口味。
Price: £1.50 per cup, which is penetration pricing compared to the cafe’s £1.80. This undercuts the competition while still leaving a generous margin. Emily might use psychological pricing, such as £1.49, or offer a loyalty card for repeat purchases.
价格：每杯1.50英镑，与咖啡馆的1.80英镑相比属于渗透定价。这既低于竞争对手，又留下了可观的利润空间。艾米莉可以使用心理定价，如1.49英镑，或者提供回头客积分卡。
Place: A stall in the busiest area of the park, near the playground. This location gives direct access to families. In future, Emily could add a second stall near the sports field or sell at school fairs.
地点：在公园最繁忙的区域，靠近游乐场的摊位。这个位置可以直接接触到家庭群体。未来，艾米莉可以在运动场附近增加第二个摊位，或在校园集市上销售。
Promotion: Emily currently relies on a chalkboard sign and word of mouth. She plans to create an Instagram page showing how her lemonade is made, and run a ‘buy five cups, get one free’ offer. These low-cost promotions fit her budget.
促销：艾米莉目前依靠黑板招牌和口碑宣传。她计划创建一个Instagram页面展示柠檬水的制作过程，并推出“买五送一”的活动。这些低成本促销符合她的预算。
7. Financial Health: Revenue, Costs and Profit | 财务健康：收入、成本与利润
Understanding financial performance is at the heart of any case study. The basic profit equation is:
理解财务表现是任何案例分析的核心。基本的利润公式如下：
Profit = Total Revenue – Total Costs
Let us build a simple weekly profit statement for Lemonade Delight. Assume Emily sells 40 cups every Saturday. Her total revenue per week is 40 × £1.50 = £60.00. Variable costs (ingredients) are 40 × £0.30 = £12.00. Fixed cost (stall fee) is £5.00. Thus total costs = £12.00 + £5.00 = £17.00. Weekly profit = £60.00 – £17.00 = £43.00.
让我们为柠檬乐构建一份简单的每周利润表。假设艾米莉每个周六卖出40杯。她的每周总收入为40 × 1.50英镑 = 60.00英镑。变动成本（食材）为40 × 0.30英镑 = 12.00英镑。固定成本（摊位费）为5.00英镑。因此总成本 = 12.00英镑 + 5.00英镑 = 17.00英镑。每周利润 = 60.00英镑 – 17.00英镑 = 43.00英镑。
| Item | Amount (£) |
| Revenue (40 cups × £1.50) | 60.00 |
| Variable costs (40 × £0.30) | 12.00 |
| Fixed costs (stall fee) | 5.00 |
| Total costs | 17.00 |
| Profit | 43.00 |
A healthy profit margin allows Emily to save for her machine quickly. If sales drop on a rainy day, profit could fall below her break-even point. Break-even happens when total revenue exactly equals total costs. For Lemonade Delight, the break-even number of cups per week is given by: Fixed Costs ÷ (Selling Price per Cup – Variable Cost per Cup). That equals £5.00 ÷ (£1.50 – £0.30) = £5.00 ÷ £1.20 = 4.17, so Emily must sell at least 5 cups to avoid a loss.
可观的利润率能让艾米莉迅速存钱购买机器。如果遇到雨天销量下降，利润可能降至盈亏平衡点以下。盈亏平衡点是指总收入恰好等于总成本时的销售量。对于柠檬乐，每周盈亏平衡杯数由公式计算：固定成本 ÷ (每杯售价 – 每杯变动成本) = 5.00英镑 ÷ (1.50英镑 – 0.30英镑) = 5.00英镑 ÷ 1.20英镑 ≈ 4.17，所以艾米莉每周必须至少卖出5杯才能避免亏损。
8. Operations and Quality Control | 运营与质量控制
Operations refers to the process of turning inputs into outputs. For Lemonade Delight, inputs include fresh lemons, sugar, water, ice, cups and the labour of Emily and her friends. The main production process is squeezing and mixing on the spot. The output is each cup of lemonade handed to a satisfied customer.
运营指的是将投入转化为产出的过程。对于柠檬乐而言，投入包括新鲜柠檬、糖、水、冰块、杯子以及艾米莉和朋友们的人工。主要的生产过程是现场挤压和混合。产出则是递给满意顾客的每一杯柠檬水。
Quality control is important because a single bad experience can lose a regular customer. Emily uses the same recipe every time, tastes a sample before starting, and checks the cleanliness of the stall. She also asks customers for quick feedback and adjusts the sweetness if needed. These methods are simple but constitute a quality assurance approach suitable for a micro-business.
质量控制很重要，因为一次糟糕的体验就可能失去一位常客。艾米莉每次都使用相同的配方，在开始前试喝样品，并检查摊位的清洁状况。她还向顾客征求快速反馈，并在需要时调整甜度。这些方法虽然简单，却构成了适合微型企业的质量保证体系。
9. Making Recommendations and Justifying Decisions | 提出建议并论证决策
Many WJEC case study questions ask you to recommend a course of action and justify it. The best answers link suggestions directly to the business’s objectives and SWOT findings. For Lemonade Delight, based on our analysis, we could recommend the following:
许多WJEC案例分析题会要求你提出一项行动建议并加以论证。高分答案会将建议直接与企业目标和SWOT分析结果联系起来。根据我们的分析，我们可以为柠檬乐提出以下建议：
Recommendation 1: Introduce a new flavour each week (e.g. raspberry lemonade). This exploits the Opportunity of changing consumer tastes and reduces the Threat of being seen as boring next to the cafe. It also builds on the Strength of low ingredient costs, as adding a small amount of fruit syrup only increases variable cost by £0.05 per cup, while the new flavour could justify a small price increase to £1.70, increasing the contribution per cup from £1.20 to £1.35 and boosting weekly profit significantly.
建议一：每周推出一款新口味（如覆盆子柠檬水）。这利用了消费者口味不断变化的机会，并降低了让顾客觉得比咖啡馆单调的威胁。该建议还基于原材料成本低的优势，因为添加少量果味糖浆只会使每杯变动成本增加0.05英镑，而新口味可以为每杯提价至1.70英镑提供理由，使单位贡献从1.20英镑上升到1.35英镑，从而大幅提升周利润。
Recommendation 2: Use part of the current profit to advertise on social media. Emily’s weakness is low brand awareness. Spending £10 per month on targeted local Instagram ads could attract 20 new customers per Saturday. This aligns with the objective of growth and strengthens her promotional mix without hurting cash flow. Justification should include a simple forecast: even 10 extra cups weekly would bring an additional £12.00 profit after deducting the ad cost, thus paying for itself quickly.
建议二：利用部分当前利润在社交媒体投放广告。艾米莉的劣势是品牌知名度低。每月在Instagram上花费10英镑进行本地定向广告，可以在每个周六吸引20名新顾客。这符合增长目标，并能增强促销组合而不损害现金流。论证应包括一个简单的预测：即使每周多卖10杯，在扣除广告费后也能增加12.00英镑利润，因此很快就能收回成本。
10. Practice Question and Model Answer | 练习题与参考答案
Exam-style question: Using the information provided, analyse one strength and one weakness of Lemonade Delight, and recommend one strategy to improve its chances of long-term success. (6 marks)
模拟题：利用所提供的信息，分析柠檬乐的一个优势和一个劣势，并推荐一项提高其长期成功机会的策略。（6分）
Model answer: One key strength is the very low variable cost per cup of £0.30, which creates a high contribution margin of £1.20 per cup. This allows Emily to price competitively at £1.50 while still earning strong profits. As a result, she can quickly build up capital for reinvestment. A significant weakness is the dependence on good weather, because the stall is outdoors and sales collapse on rainy Saturdays. This makes revenue unpredictable and could discourage helpers from attending regularly.
参考答案：一个关键优势是每杯很低的变动成本0.30英镑，这创造了每杯1.20英镑的高贡献毛利。这使艾米莉能够在定价1.50英镑与咖啡馆进行竞争的同时赚取丰厚利润，从而快速积累资本用于再投资。一个显著的劣势是依赖好天气，因为摊位在户外，下雨的周六销量会骤降。这使得收入难以预测，并可能降低帮手们到场帮忙的意愿。
To improve long-term success, I recommend Emily develop a simple weather contingency plan — for example, investing in a pop-up canopy and posting on social media when the stall is open. This reduces the threat from weather, keeps customers informed, and protects revenue. This strategy directly addresses the identified weakness and builds on her existing strength of low costs, because a basic canopy is a one-off fixed cost that can be funded from just two weeks’ profit.
为了提高长期成功的机会，我建议艾米莉制定一个简单的天气应急计划——例如，投资一顶折叠式遮阳篷，并在摊位营业时在社交媒体上发布消息。这可以降低天气带来的威胁，让顾客随时了解情况，从而保障收入。该策略直接针对已识别出的劣势，并利用了她现有的低成本优势，因为一顶基本的遮阳篷只是一次性固定成本，用两周的利润即可购得。
