When he was at Shelby, Constantine was always one of my "go to" guys for real-world stories from the implementation trenches (he was one of many who confirmed the early challenges of Ariba cloud P2P limitations from a systems integration perspective). Given his experience advising clients on systems selection and implementation in the consulting world, I have no doubt his skills will be put to great use at Aberdeen. Moreover, Constantine will do much to break the often false stereotype of industry analysts being unapproachable, standoffish and aloof when it comes to what actually transpires in the field.
Please join me in wishing Constantine luck in his endeavors at Aberdeen. He's from the school of hard knocks and is a no BS type of guy who I think will make Aberdeen's research that much more grounded and pragmatic, hopefully finding a way to help the firm deviate from the entirely scripted quantitative studies which fail to highlight the ability of truly skilled and expert analysts to provide advice based as much on what they know as what they interpret. Moreover, now that Constantine has an expense account not coming out of his own K-1 distributions, I look forward to his extravagant wining and dining of Spend Matters team members (in exchange for industry insight and scoop and business leads, of course...)
