Dodge,I am an experienced supply chain consultant who has worked for and with the Big4 supply chain practices and a couple of SC boutiques.Two of the best SC consultants I know (Snr Cons & Mngr) are non-graduates, both having been recruited from 3rd party logistics backgrounds - so don't let the degree thing put you off at all. SC practices really value people who have 'been there and done it' so long as:-You can handle yourself in front of senior clients i.e. give them confidence you can get the job done and then do it.You know the fundamentals of supply chain theory and how it works in practice.You are sufficiently self-sufficient in doing analysis / number crunching - if you think you'll have an army of SC-savvy people to do this for you quickly and accurately, think again, you'll come across a few but in my experience they're rare.My view is that SC people with solid experience soon become valuable sellers as well as doers - partners appreciate taking real-world SC issues and 'war stories' to prospective clients. Ability to sell as well as deliver is the quickest route to promotion.From your original post I'm sure you have a wealth of project experience to fall back on. One thing to be aware of is that at interview (and particularly if you are asked to do a case study) the emphasis will be on being able to see the 'bigger picture' and articulate the improvement opportunities concisely and persuasively - testing your ability not only to do the project work but identify opportunities to sell-on and build long-term relationships with clients.Your real challenge will be to quickly establish yourself as someone who can work and create selling opportunies independently (not solo, just low maintenance), and for your sake, be able to work ouside the normal SC frameworks, methodologies, processes etc that the bigger consultantcies (tediously) fall back on when there's nobody around with the experience and confidence to take an assignment/opportunity by the scruff of the neck.What you'll learn and enjoy will be largely due of the variety of problems you'll come across (in lots of different sectors) and working with some very good people to deliver under pressure - not from exposure to a consultancy's 'proven supply chain toolbox'.If you're commited to the lifestyle (sounds like you are!) then joining a SC practice could be a great opportunity and very enjoyable - don't let the 'irrelevant degree' (it's not) dent your confidence and don't be surprised how valuable your experience and knowledge could be in a 'typical' Big4 practice.Boutiques are also an option but in my opinion the opportunities for promotion/reward can be more limited and you could risk becoming a 'jobbing' project consultant forever - obviously not the case everywhere, just my limited experience.From what you say, it sounds like you want to properly do the 'consultant thing' and if that's the case, IMHO, a Big4 is the place for that.Good luck with whatever you decide. Any more specific questions, just let me know.
