Wiley has now created a way to sample The Five Behaviors of a Cohesive Team experience (with the MBTI compatible version). Send Sue an email and she'll send you an access code to try the whole 5B experience for free. You'll get an actual report showing your results within the Decision Tech team. That's the team in Lencioni's book.
There will be a 5B DiSC version demo coming later and we'll let you know when that happens.
In the meantime, see for yourself what the 5B experience is all about. Contact Sue at firstname.lastname@example.org.
