Would love to be a fly on the wall for a couple of months to see what corporate CxO's actually do.
Surely I could do a mediocre job as a CxO by parroting whatever is hot on Linkedin. Probably wouldn't be a massively successful one, but good enough to survive 2 years and have millions in the bank for that, or get fired and get a golden parachute.
(half) joking - most likely I'm massively trivializing the role.
"Surely I could do a mediocre job as a CxO by parroting whatever is hot on Linkedin"
Having worked for a pretty decent CIO of a global business I'd say his main job was to travel about speak to other senior leaders and work out what business problems they had and try and work out, at a very high level, how technology would fit into that addressing those problems.
Just parroting latest technology trends would, I suspect, get you sacked within a few weeks.
A charitable explanation for what CxOs do is that they figure out their strategic goals and then focus really hard on ways to herd cats en masse to achieve the goals in an efficient manner. Some people end up doing a great job, some do so accidentally, other just end up doing a job. Sometimes parroting some linkadink drivel is enough to keep the ship on course - usually because the winds are blowing in the right direction or the people at the oars are working well enough on their own.
Funny enough, the author of this blog post wrote another one on exactly that topic, entitled "What do executives do, anyway?"[1]. If you read it, you'll find it's written from quite an interesting perspective, not quite "fly on the wall," but perhaps as close as you're going to get in a realistic scenario.
