I am now officially a Certified Scrum Practitioner.
So it signifies that my peers recognize that I understand Scrum pretty well. The certification shows I have actually applied Scrum for real, on a real project, in a real organization, for real stakeholders. It’s not a big deal, really. It’s just a token from an independent group of people–not me, not my friends, not my coworkers or business partners–that I probably know what I’m doing. But there are only about 1,000 CSPs in the world, so it helps distinguish me from people who haven’t been similarly recognized by their peers.
