I had absolutely no knowledge of Scrum, until a colleague started talking to me about it, and I became minimally curious about the subject.
From there, we decided it's something we should gain more knowledge on, and possibly even try-out in our organisation. So, we signed up for the CSM course, with the intention to learn more about the subject and decide whereto from there...
Wasn't I pleasantly surprised, we attended CSM, and not after the course, not even after the first day, but minutes after starting, I was hooked. It's amazing how this world had been "unknown" to me, and my colleagues, in the sense of it all, until May 2011. Since then, I've never looked back, and neither have they.
In Aug 2011 we took yet another step, attending the CSPO course. A lot of the CSM teachings were revisited, refreshing our knowlegde gain from the previous course, but yet we continued to learn.
One of the greatest experiences of these courses are being amongst others whom are just as intrigued as you are, and learning from their experiences.
Exploring different ways in approaching the same situation, becoming more efficient and just overall better at it.
It's now Mar 2012, and boy have I come to learn, I've experienced, grown and it is ever continuous.
Still majorly in love with Scrum.
Best advice I can give anyone, read up on it, try it out, as I, you too will become intrigued by it, later unable / not wanting to go back to the waterfall ways that we all are so familiar with.
