Agree/disagree…1.When we started considering DevOps, it was difficult to find a good comparable organization, in higher ed or otherwise, to use as a role model.

2.The organizations that we looked at as examples when we started considering DevOps were primarily for-profit companies.

3.It would have been easier to start with DevOps if we had a good example from higher education to look to.

4.We had to decide for ourselves what DevOps meant for us when we got started with it.

5.When I read articles with justifications for why DevOps is positive for for-profit companies, the examples and arguments don't make sense to our situation in higher ed.

Agree/disagree…

So, we are not alone!
