‘We made the best decision we could given the information we had at the time.’
And it might turn out you made the wrong decision or didn’t choose the best decision of the ones available…but see the opening line…all you had was what you had at the time.
So if ‘at the time’ is a constantly limiting the ability to make the perfect decision, the temptation would just be to delay, gather more intel so the pool of information is bigger at the time of the decision.
But life doesn’t work that way. There’s not enough time and the decisions are too important to keep delaying.
