My opinion is that any player is ready to be a CEO any time they wish - they just might be a bad CEO.
Of course, the members of their corp might be bad corp members, so they can learn to be good together.
Obviously, bad and good are rather subjective here. Someone might be really effective at herding a small amount of HS miners and keeping them “safe”, fat, and happy, including knowing and instructing when to drop and reform the corp. They might not fare too well leading other types of corps, such as a FW Unit, merc/wardec outfit, WH residency, or NS bloc. These all require different leadership skill sets and can lend to different leadership styles as well.
There are probably a few skills that do make a superior CEO that are found across the board. What these are likely needs its own thread. However, assuming that these shared skills can be identified, then they could be taught - but only if a prospective or current CEO wishes to pursue them. I don’t think that an in-game tutorial would work so well. These skills are likely to be soft skills that won’t be able to effectively transmitted in an artificial setting. Especially to someone without any actual leadership experience.
EvE is a game about doing. A player can read all the forums and blogs, watch all the videos, listen to all the veterans and conspiracists that she wishes to. At the end of the day, that pilot will need to get in game and DO these things.
Having said this, I also believe that doing diligent research is also part of EvE. Find your own answers in whatever way you can - read, ask, observe, experiment, etc. The current tutorials can only go so far, and for ‘what-button-does-what’ I don’t have a problem with them. But beyond the technical operations, I don’t think that in-game tutorials will help in teaching someone to be a good CEO.
