|---|---|---|---|
Purposedifferent | When the picture of the problem still needs to become solid, it asks about real situations and consequences. It separates genuine suffering from mere interest in a solution. | When an idea can first fail or grow through genuine hands-on support, it relies on manual work instead of automation. It shows whether user value holds up even under manual execution. | With defensive reactions to problems, the method shifts the view from justification to ownership. It makes visible which reaction stage a person or team is currently stuck on. |
