The company where I work decided to join the league of companies practising agility at the turn of the year.
Everywhere you turn, it's "agile", "agile".
I’ve being involved in complex software deliveries and maintenance using scrum ever since then, so I gained more practical knowledge.
I'm certified with PMP, Prince2, but in terms of agile, Scrum is way different, very interesting, more about additive product deliveries in short cycles
So, I decided to explore the concept. I preferred the scrum.org as I could see their demand for learning is thorough.
