Turn a business idea into questions you can answer
You may already know what you want to sell: a cleanup service, a repair visit, a design project or a useful digital resource. The harder question is how the whole business would work. Who needs it, how will they find you, what will they agree to buy, and what happens after they say yes?
Josh Kaufman’s The Personal MBA is useful here as a reference for thinking through those connections. In his official explanation of the five parts of every business, he identifies value creation, marketing, sales, value delivery and finance as interdependent processes. In plain terms: create something useful, attract interested people, reach an agreement, fulfill the promise and understand the money that keeps the operation working. A strong idea needs attention across those processes.
This study guide uses the 2020 tenth-anniversary edition published by Portfolio, paperback ISBN 9780525543022. Several videos discuss the earlier book or related business ideas; their labels explain the relationship. You can use the author’s free concept library alongside your reading.
Look for the missing connection
Imagine a small service that helps contractors leave an ordinary work area tidy. As an example for this exercise, the value might be a clearly defined cleanup job. Marketing would be how an appropriate customer hears about it. Sales would mean agreeing on what is included, the price and the terms. Delivery would mean completing that agreed work and checking it with the customer. Finance would mean understanding time, costs, payments and what remains.
That example is our illustration, not a case study from Kaufman’s book. It also leaves important questions open. What cleanup is within your skills and equipment? What would the customer consider finished? What travel, materials or disposal costs would the job involve? A broad promise such as “I’ll take care of everything” makes those questions harder to answer.
You can apply the same map to many ideas. A tutoring session, an editing service and a small software tool have different delivery needs, but each still needs a useful offer and a way to reach a customer. Use the map to find what you need to investigate before increasing your commitment.
Before you read or watch
Pick one idea and one kind of customer. Finish this sentence: “I think I can help ___ do ___ by offering ___.” Describe an observable task or problem rather than assuming everyone wants your solution.
Then ask yourself:
- What have I actually heard a potential customer say, and what am I only guessing?
- Which part of the work can I already do reliably?
- Where could an unclear promise create a disagreement?
- What would I need to learn before deciding this idea is worth pursuing?
In the Knowledge Project’s companion notes, Kaufman recommends sketching a business plan under the five headings. The exercise below adds our own assumption-and-evidence columns so that the map becomes a small investigation.
SelfGrowthVideos practice: build an evidence map
This is our original exercise inspired by the published framework, not an official Personal MBA worksheet.
- Make five rows on a page: value creation, marketing, sales, value delivery and finance. Add three columns: my current idea, what I am assuming and what I can check.
- Write one concrete sentence in each row. For delivery, name the work and the check for completion. For finance, list the time and costs you would need to estimate; do not invent a profit figure.
- Mark information you already have separately from guesses. “A contractor told me cleanup delays the next crew” and “contractors will pay my proposed price” are different levels of evidence.
- Choose one uncertainty that you can investigate with little commitment. For example, ask a willing potential customer how they currently handle the problem and what an acceptable result looks like. Listen before presenting a solution.
- Record what you learned and change one sentence in your map. An answer that weakens the idea is still useful evidence.
This is a learning trial. It does not establish customer demand or predict earnings. Start with a conversation or a safely scoped demonstration, and work through the Business Launchpad before taking on paid work. Its separate planning areas help you investigate responsibilities that a five-row map cannot settle.
Review the idea after your first check
What became more specific? Which assumption remains unsupported? If a customer expressed interest, what did they actually agree to, and what have you inferred? Decide whether to revise the offer, investigate a different question or set the idea aside.
Keep the original map and your revision. Comparing them makes your learning visible. You are trying to understand a business process, not prove that your first idea was right.
Choose a useful next step
Continue with the Build a Business reading path, The Lean Startup study guide or the Side Hustles learning areas. To work on the customer question, try listening before designing an offer and choosing a specific first audience.
The five videos below offer different ways into the material. Three are author talks or interviews; two are clearly identified reviewer discussions. Their titles are the uploaders’ headlines, including promotional language. Use the questions beside them to examine the ideas; a headline is not an income promise, and a discussion is not a substitute for checking the book.
