A colleague and I are about to do the practitioner five day course. Went on a seminar last week. It's about £ 1000 all in at the moment so it's a good time to do it. From the seminar it all looks pretty common sense, anyone with any project management experience should be pretty familiar with the concepts, it's just the terminology you need to get your head around. I'm purely doing it for the CV, no chance what so ever of using it properly where I work, principle number one, have an viable business case as you move forward – FAIL.
It's becoming a pre-requisite for many project management type jobs and as I said it actually looks quite sensible in it's approach. We're looking to do it through a training provider called SPOCE.
