DISC works by measuring four fundamental factors in a person's behaviour, and using those four factors to describe their personality by developing a 'DISC profile'.
How do we go about creating a profile of a personality? We start, naturally enough, with a questionnaire: a set of questions structured to focus on certain key elements. For DISC, these questionnaires typically consist of a series of just twenty-four questions, and each question is made up from four different options (which can be simple adjectives or descriptive phrases).
The person answering the questions chooses two of these options, one that best represents their behaviour, and one that's least relevant to their general approach. Once we have those answers, they can be rated and calculated to produce a set of results. With an automated DISC system, of course, this is all done automatically.
An obvious question here might be: can we measure an entire personality with just four factors like this? In fact, we can't, but what DISC can do is focus on a series of key traits that directly affect a person's behaviour and performance. There will always be other factors to consider - notably things like experience and knowledge - but DISC focuses on more fundamental questions about the ways a person will naturally react in different situations.
You can get a feel for the way DISC works by considering a diagram we call a Style Card, which relates to a person's Assertiveness and Openness. Here are a couple of examples that give a broad overview of two quite different personality styles:
This example shows a highly Assertive person, but generally less Open to others. A person like this tends to be determined and demanding in style.
This is far more Open person, sociable and accepting in their general approach, tending to be less direct or forceful, but working more effectively as part of a group.
From basic information like this, gleaned from a DISC questionnaire, we can put together a graph showing the relative Dominance, Influence, Steadiness and Compliance that drive a person's approach to their life and work. In fact we can go further and build a series of graphs that look at different motivations in different situations.
If you're interested in finding out more about the technicalities behind DISC, we provide comprehensive reference material that covers all of this in detail, and we even offer an interactive online Training Course that explains DISC from first principles.
Bear in mind that you don't actually need to understand the theoretical principles behind DISC to use it. The profiling system takes care of the interpretation for you, with an advanced expert system that produces a personality report in plain language.
