If Birkman® Express is Birkman "lite", is it worth having?

Emphatically, yes!

Birkman Express doesn't give you all the fine-grained detail available in the full version - but what it does give you is a) still way more powerful and detailed than any other tool of this kind and b) is enough to understand a great deal about what motivates, supports and stresses you. By way of illustration, the team performance work that Elaura does with corporate and public sector clients usually begins with exactly the same data that is available through Birkman Express, and only moves on to the more detailed data when very specific performance issues are being addressed.
