Idea Worksheet.

An idea is a start. Give it a next step.

Put your idea into a few clear sentences. Then choose one thing to learn before you go further.

Books, a brass key, an open doorway, and a table for sharing ideas.
A LITTLE ROOM TO THINK. A PRACTICAL PLACE TO BEGIN.
What to bring
An unfinished idea, a person you want to help and one question worth testing. Unknowns are welcome.
What you keep
A short plan describing the person, the question and a practical next test. This is an early idea worksheet, not a full business plan.

Compare relevant resources and services by what they offer, their cost and how you can use them.

Start with three useful questions.

You can begin with an unfinished idea. The point is to make the next question easier to see.

01 / THE PERSON

Who is this for?

Picture a particular person in a particular situation. What are they trying to do, and what gets in their way?

“People who cycle to work and struggle to fit a bike repair into their week.”

02 / THE QUESTION

What do you need to learn?

Pick an assumption that matters to the idea. Write down what you know and what you are still guessing.

“Is getting to a repair shop actually a problem for these people?”

03 / THE NEXT STEP

How could you find out?

Choose a small action that produces something you can examine: a conversation, an observation, or a simple trial.

“Ask five bike commuters about the last time they needed a repair.”

Leave with a next step of your own.

A short worksheet turns these questions into a plan you can copy and keep.
