What's after the PSM I Certification ?

Rami, the scaled scrum would be focused at a framework level as opposed to the PSPO at the role level. It depends on how you want to position your expertise. Realistically, you could go for both. From my perspective and what I see the needs and organizational directions, I'd want to stay more 'big picture' with the Scaled Scrum. But that is based on what I see and where I want to go. I had earned my PSM b/c I had been asked to change roles (though, that never happened).

What is your motivation? How do you want to position yourself?

Rami,
Congratulations on your new certification.
How do you see it being apply in construction? Of those other certification any that have more potential in construction?

Congrats Rami, I'm sure this achievement will help you a lot down the road. If you see the potential, I think you should go for both certification. Anyway it depends on your individual priority and expertise.
