Hi there,
I'm a developer and I want to get a certification from scrum.org, because I want to introduce Scrum in my company. I wonder which of both certifications (PSM and PSD) is more appropriate. Can I be a Scrum Master when I get a PSD certification? Apparently PSD is harder to get, but does this mean it has a certain reputation over PSM? Does it include PSM? Since I am developer now, my co-workers will ask me about implementing specific techniques if I try to implement Scrum.
