What development methodologies have you encountered in your career? Did these seem aligned to the purpose of the system in question? What challenges did you find (or can you imagine) the developers may have run into? What challenges do you think the Security people ran into for that system? What benefits do a Maturity Model deliver and how do you go about choosing one? How would you measure the maturity? Have you ever seen such a model in use? Change management is often a sleepy and uninspiring topic. Have you ever seen it fail? What was the effect? If it were you swooping in after the problem, what best practices would you suggest to them and why?
