Datawarehouse Career Progression Path

In My opinion, actually, you can think of going ahead with your datawarehouse career in 3 Directions

1 - Technical BI Solution Architect Role --> Requires you to be totally focuced on the Technical Side. Doesnt matter about the business domain (though sticking to a specific Business Domain will be an added advangte.)

2 - Techno functional Business Analyst Role --> Here you will be more inclined towards a Business Domain, a specific functional area. It will be a mixture of technical and functional role.

3 - Corporate Performance Manager Role --> It is a total functional area, where in your role will require to look at the corporate from a 50000-feet level and analysis how can you measaure the performance and improve on a continual basis. It requires a great level of expertise in terms of # of years in technical and Business Area.

Also, it depends upon your interest.
What kind of thinking you have ... A pure Technical or Techno Functional or just functional. I have witnessed the thinking changing as the time progresses.
