02 · The idea

How I understand it.

Start with a customer need and list the components of the current offer. Then apply a deliberate change: remove a component, divide a task, combine functions or give an existing element a new job. Each change creates a concrete possibility to examine. Consider who would benefit, what becomes easier and which drawbacks appear. Constraints such as a fixed budget, limited space or a short delivery window focus the search and help people evaluate ideas against real conditions. Judge the resulting concepts by their usefulness to the customer as well as their novelty. Select a small number for testing and observe whether customers understand the value. This approach gives a team a repeatable way to explore improvements to products, services and the buying experience.

03 · A fictional example

Put it into a business.

A meal-kit company explores a service for small kitchens. Its team removes the assumption that every ingredient needs separate packaging. Combining compatible ingredients reduces the number of containers and preparation steps. A trial with ten households measures storage space, preparation time and satisfaction. Feedback reveals which combinations help customers and which need changes before a broader paid launch.
