Who Is a Customer?

Life Skills · Entrepreneurship · conceptual

Understanding that a customer is someone who buys what you make or do; thinking about what customers want and need; the idea that businesses serve people

What mastery looks like

  • Define what a customer is in their own words
  • Suggest what a customer might look for when deciding whether to buy something (quality, price, looks nice)
  • Explain why it matters to think about what the customer wants, not just what you want to make

Check your understanding

If Who Is a Customer? was planning to sell lemonade at a school event, could they think about what would make people want to buy their lemonade rather than someone else's?
