- It gives you a good basis to understand what SOA is all about
This way you can put this into better perspective when using or selecting SOA tools like ESB and BPM. I always compare it with learning first Object Orientation before diving into C++ or Java. This way I truely believe you get better (reusable, maintainable) code.
- Just that little more focus on the content then by just reading a good SOA book
It forces you to really study the material.
- It helps when planning an architecture roadmap
I know that you always get presented the ideal SOA picture, but at least it helps you when you have to define a SOA roadmap. It also helps you where to give attention and what kind of discussions you have to do. This way it will help to change the mindset of developers/designers/architects/business.
However the question remains "What is the value of this certification within the market and how is it valued by customers?". I still do not discover the questions by customers, but Java certifications are valued. Maybe it is a question of time?
