First, you need to identify the blinders; next, you need to identify the trade-offs; and then you need to decide and iterate on a solution.
My strategy is different.
1) Identify the success/evaluation criteria (including deal-breakers). That is, what things are the most important. (This is closest to their #2, trade-offs; but we won't see trade-offs in my strategy until #3).
2) What are all of the options? List everything. This is for everyone's good; don't leave room for "but why aren't you considering <x>?" This should address blinders, their #1.
3) Evaluate the options (#2) against the criteria (#1). That is, decide which option has the trade-offs that best fit the success criteria (including best avoid the deal breakers). As I've said before, it's not about _finding_ the right answer, but figuring out which has the best trade-offs per your priorities.
