04 · THE RESPONSEONE OF THE NINE BOXES
What is the smallest useful way to address the problems?

What this square means

The Solution square outlines what you plan to deliver. Keep it brief: one simple idea or feature linked to each major problem. You are describing a starting approach, not a final feature roadmap.

What to write in it

A filled-in example

CampusKit’s possible solution: (1) A searchable list of available project tools. (2) A one-week rental or loan option with simple pickup. (3) A reservation and return confirmation system.

The first pilot might simply be a spreadsheet of twenty tools and a human-managed checkout desk. That could test demand before building software.

A common mistake

Designing a sophisticated app with payments, delivery tracking, subscriptions, and recommendations before knowing whether students will borrow tools.

A simple way to test it

Run a two-week manual pilot with a small inventory. Measure actual reservations, completed pickups, returns, and repeat requests.

How it connects to the rest

The features should solve the Problem, not distract from it.

Add a short, specific statement to the matching box on your canvas. Treat it as a hypothesis until you have evidence.
