Change in a University
Leah, if you are evaluating the extent to which change has taken root in the University, I suppose you are really having the right tool - ADKAR model. Usually I find it useful especially in measuring the buy-in from stakeholders.
If however, you are assessing the readiness of the University to embrace change, you may be better-off using a different model I suppose. Usually this is mostly predetermined by the nature of issues to be addressed. I find it that there is no one-fit-all model. My best approach has always been in developing a tailor-made diagnostic tool - especially in determining the leadership capability to drive and sustain the changes envisaged in the organisation. I have my own too developed for this purpose.
