The Osborn checklist provides suggestions for critically questioning existing things by consciously changing individual properties. By changing various properties in different ways, what has been modified appears completely alienated to the observers. In looking at this modified version, they can then ask themselves what other object corresponds to this “modified existence” and how in that object certain problems have been solved. The questions Osborn provides as suggestions are, for example: What is like this? What can be copied? Are there alternative uses if the existing is so modified?
