Assessments are often a good place to start to get a good perspective on a company's personalities and relationships patterns. They can provide an objective, outside metric on a number of different factors and influencers. That said, assessments have the obvious substantial limitation in that they can only provide a very limited perspective on complex and changing human behaviors and personalities. Whatever broad generalizations any assessment provides, we have to realize that it is not the last word, and is barely even the first word about an individual. We have to know that at best, assessments provide "usually" or "often" predictors about people, and so we have to approach results with plenty of flexibility.

This assessment provides an in-depth psychological profile that is interesting to the individual but is difficult to gain value from across a larger number of employees.
