RDM– AHP: scientific on intutive?
While studying AHP, I came across conflicting idea about the nature of this particular decision tool.
Whereas some authors suggest that it is a combination of subjectivity and rationality, others suggest that is is entirely based on scientific judgement.
In my view even though the approach may be scientifc in nature, it is largely affected by the subjectivity of the decision maker. Most importantly, the factors that a decision maker chooses for the model can largely determine the validity of the results. However, that suggests that subjectivity is never the problem of the tool itself but the decision maker. This makes me think that the decision maker himself has a huge role to play. No matter which decision tool you pick, in the absence of an effective and objective decision maker, the tool by itself will be dysfunctional.
