BDM is designed for use in making deliberative decisions—those made based on canvassing and weighing up the arguments.
In these two key elements, BDM is similar to the natural or typical way of making decisions.
However, it differs from typical, informal decision making by providing a structured, semiformal framework, and using visual language, taking advantage of our ability to grasp and make sense of information faster and more easily when it is graphically presented.
BDM aims to support the decision process, making it easier, more reliable and more accountable.
It addresses some major problems that can afflict business decision-making the way it is generally done, including stress, anxiety, time pressure, lost thinking and inefficiency.
