know your solution before letting others adopt it

When you are an expert on a team, don't rely on the opinions of others less informed in your discipline. If you propose a solution that others quickly adopt, be sure of the solution. If the solution is incomplete or lacking in some way, the others on your team may simply reply that they relied on the expert in accepting the solution. They were understandably ignorant. You, on the other hand, are the expert.
