ECO.10:1 - Problem frame

Use this pattern when a method or technology uses less of a resource per useful result and you need to know whether total resource use will also fall. Start by naming the useful result, resource, boundary and comparison without the change. Then follow the responses which can change total use.

The useful result is a conditional total-use comparison or a response threshold that matters to the decision. A fixed-output engineering comparison can stand alone when that is the stated question and output truly remains fixed.
