We talked about the 4 key questions yesterday. Let's try them out against anything you did and you will see the problem - if there is any:
"What are we doing?"
"How are we doing it?"
"Why are we doing it?"
"How do we know if it's working?"
My concern is the last one. How do we know if _____________ is working?
(fill in the blank with anything that needs an answer, e.g. the toilet, the final project)
If you cannot provide an answer, it is useless!
