Didactic Interaction – this is used when decisions to be taken are dichotomous in nature. For this method, instead of one group of experts, two group of experts are created, one favouring a “yes” decision and other favouring a “no” decision. The first group enlists all the “pros” of the problem solution and the second group lists all the “cons”. Each group then generates the list of justifications for their decisions and then interact and discuss with their findings. With mutual interactions and discussions, both the groups arrive at a consensus and a decision is taken.
