This was my takeaway too. Too much talking about doing at big corporate companies, and not enough actual doing. Drives me up a wall.
No, if the CEO tasks an executive with something that guy/gal should responsibly* think about the task, analyze it, break it down, and hand off "smaller" chunks to underlings.
And smaller could even mean a lot more detailed but with better scoping. Fixed budget, concrete goals, etc.
* - said exec should/must ask the CEO about the priority of this task, what other tasks will be demoted, is it possible, do they have enough budget, resources, timeframe, etc.
