Timing is Key - If you wait until it's obvious, it's too late

tjmaxal made a good point in another comment about specifically focusing on big picture for one month per year. I think it'd be useful to do that on different levels (one month per year, one week per month, etc). Managers could definitely measure time spent on big picture projects or automation versus handling crises. There are people I've worked with that spent 80% of their time handling crises. That should be a huge warning sign that aren't planning properly, or they're cleaning up somebody else's mess. Either way, that's a situation that'd be worth poking into.
I can't really say whether it's MBA wankery or useful business process, though.
