Most spreadsheet work that goes nowhere started without a decision attached. Someone asked for a report, the report was built, and nothing changed. Good analysis begins at the other end: with the choice a person has to make, the options in front of them, and what evidence would make one option clearly better than another.
Name the decision, not the topic
Customer churn is a topic. Whether to extend the onboarding call from fifteen minutes to thirty is a decision. The second version tells you what to measure, which customers to look at and how precise the answer has to be. Write the decision as a sentence with a verb and a deadline, and name who will act on the answer.
List the options on the table
Every decision has at least two options, even if one is to change nothing. Writing them down keeps the analysis honest, because the data has to discriminate between real alternatives rather than simply describe the situation.
Decide what would change your mind
Before opening a single export, ask what result would push you toward each option. If no plausible number would change the choice, the analysis is not worth doing. If a rough estimate would settle it, do not build an elaborate model.
Action Step
Write one decision you currently need data for, in a single sentence with a verb, an owner and a date. Beneath it list the options, including doing nothing. Then write one line for each option describing the result that would make you choose it.
This lesson is educational and reflects general practice. Results depend on your situation, market and effort; adapt what you learn to your own context.
