Scott, Thanks for the comment. Well said. I was asked to present this topic to set of classic service desk folks of various sized orgs a few months ago. Not top level management or procurement or contract management people, and I was wondering what they would think. By the heads nodding and the comments afterwards, service desk people are feeling the associated pains today.
After years of consolidation and rooting out non-sanctioned IT, the forces of entropy are back at work. Bring your own device and use your own app moves to secure your own infrastructure (via Amazon or whomever) and procure your own (departmental) app and so-on and so-forth.
