Its similar to the concept of forcing them to take personality and aptitude tests. It serves no purpose, and takes time and money. I remember having to sit through a meeting after taking one of these where the presenter explained the best way to approach members of different personality styles. My takeaway was that this is the real world and I am not going to prep to understand someones personality profile before every meeting or human interaction. No one at the manager level or above in the company as far as I am aware ever utilized it again. Lower level people tried but it had no positive results or changes to their career so they eventually abandoned it and worked for their C.O.L. increase. This is a 5k+ employee company.
Just treat your employees like real people who have lives and value them, best way to get employee engagement.
