So how do you channel all that energy back into the normal work week? Timebox it? 1 day a week for 6 weeks after the off-site, to work exclusively on initiatives raised? Off-sites usually serve as a great reminder of how nice it would be if you didn't have a ton of stuff to do and could just get dinner in nice hotels. Maybe you need a rule of thumb that says for each strategic initiative raised, you need 3 tactical actions that can take place in a given time frame and no future off-sites can be scheduled until they are done (in one way or another)?
