There are plenty of books, thinkers, and pundits covering management techniques and leadership out there.  Moving beyond buzzwords and acronyms you begin to get to fundamentals.  One fundamental I use is the notion of "spot it, got it."  We have all been in meetings or discussions where a problem is restated over and over or someone will point out that something needs to be done about X.  My approach to these scenarios is that if you bring it up, you own it – be that figuring it out, researching it, or coming up with the solution.  I sincerely believe that merely stating a problem without a proposed solution is intellectually lazy.  You’d be surprised what kind of discipline that this will bring to a team or company – as well as drive creative thinking from those around you.
