Amazing; this is just about how I approach it, except I have a bit more slack for the "CIP": 90 days is not a long time at many organizations larger than a certain size (say, about 100 people). I'm generally content as long as progress is being made to improve at a reasonable pace, and few or no regressions occur.
To be fair, the only time I saw a complete reversal of state in a short period of time was during the dot com implosion. The CEO at the company just lost it (he was under a lot of stress), and the working conditions went from meets to needs improvement remarkably quickly.
And its possible to have one aspect being wonderful to compensate for another aspect which is not so great. For example the company mission might suck but you really like your manager and your co-workers.
