A major step forward came with the development of the DISC Graph or DISC Profile, a graphical
shape representing aspects of a persons behaviour in a form that was easy to understand with little experience
or training.
Now, it was possible to present the complex results produced by a behavioural profile in the form of a simple
profile shape that could be understood and interpreted by the layman. While some training was still
necessary to analyse a DISC profile shape, the psychological and statistical background that had once been a
prerequisite of profiling was no longer necessary.
