Risk matrices and the semiotics of colour


Just updated my post on Designing a Better Risk Matrix with some material on the semiotics of colour and the advantages, as well as disadvantages, that it’s use in constructing a risk matrix brings.

    I am asking about the disadvantages of risk matrices.
    And is there a deference between risk matrices and risk matrix

      Hi Ramy, see my post Decision Theory and the Risk Matrix for a discussion of their limits. The comments thread for this post is quite useful as well. Risk matrices are simply a thinking and decision making tool, but they can’t make a subjective risk assessment quantitative… If you’re distrustful of subjective, ‘professional judgement’ based assessments then you should be just as distrustful if a risk matrix was used. And no matrices is just the plural of matrix.
