As a manager I'm guilty in part of driving the cult of speed

However I noticed that whether a team member thought for a day, or thought for a week, the result was essentially the same. The tactics may have more details but the overall plan and impact id expect was roughly the same. They had blind spots, opportunities that could make it more impactful that only came to light when they talked thru it.

So for me, it was better to touch base sooner than later and get the broad plan right, then let them figure out the details and get to it

(Note I work in marketing, not engineering)
