I thought your question was really interesting, and I wasn't aware of any research in the area. I know a bunch of folks are looking at creativity and ways to measure it, but I couldn't remember any of the top of my head. I just ran across this article on imagination, which I thought might be of help to you. You can look up some of the researchers they are citing. Hope it helps.

The Encyclopedia of Creativity lists several methods to measure creativity in organizational environments (highly recommendable book anyway):

Technical Audit for Creativity of Organizations. Stein MI (1959)

Epstein Creativity Competencies Inventory for Managers.  Epstein R (1998)

Jones Inventory of Blocks. Creativity Research Journal (1991),4, 303–315.

Creativity Audit for Organizations. Rickards T and Bessant J (1980) The creativity audit: Introduction of a new research measure in programs for facilitating organizational change, R&D Management10(2): 67–75.

Climate for Creative Productivity Index, Witt and Beorkrem (1989) Creativity Research Journal, 2, 30–40.

Hope this helps.

In an act of self-promotion, I would find it interesting to include playfulness as a personality trait.  It has been shown that PF is associated with creativity or innovative behavior at work; it also seems to be associated with group cohesion and team work. If you are interested I can recommend some literature and measures. 

From experience I can tell you that there are a lot of innovative ideas in an organistation, but not seldom the staff is lacking knowledge and vision to be able to appreciate them, It would help the staff to come down from the throne and talk with the people at the shop floor

 Sven Form,Thanks for the recommended links, it is useful to look at. Although many are closed access. But still, few meet the descriptions of procedures of diagnostic techniques of creativity.

René Proyer, Thanks for the offer.I would be grateful. if You will give me recommend some literature and measures

Do you want assess the creativity of individuals or creativity of organizational groups and teams as a whole?

Sven Form, I want to diagnose individual creativity

Then I would suggest a divergent thinking test, for example with a Alternative Uses Task.

Mike Allison,big thanks for the useful link. indeed, the author has interesting links
