An abstraction ladder allows you to frame your problem in order to come up with a solution. It asks the “why” questions for the more abstract ideas from your initial problem statement and the “how” questions for more concrete ideas. Discovering these two sides of the problem will help you and your team be able to understand aspects of the problem that may not have been obvious before.
When your team feels stuck on a problem that needs to be solved, using this abstraction ladder to break up the various aspects of “why” and “how” can allow you to find solutions within defining the problem.
