Categorizations of severity cannot be made objectively for uncertain consequences.The can result in suboptimal resource allocation as effective allocation of resources to risk treatments cannot be based on the categories provided by risk matrices.They can mistakenly assign higher qualitative ratings to quantitatively smaller risks to the point where with risks that have negatively correlated frequencies and severities they can lead to worse-than-random decisions.They can correctly and unambiguously compare only a small fraction of randomly selected pairs of hazards and can assign identical ratings to quantitatively different risks.Risk Matrices they have the following limitations: In the hands of the inexperienced, the biased or individuals with an agenda, they can of course generate misleading ratings. They are not without flaws however and are definitely not an answer for all ills. Present complex risk data in a concise visual fashion (e.g.Focus decision makers on the highest priority risks.Help keep participants in a facilitated risk workshop on track.Provide some consistency to prioritizing risks.Promote full-bodied discussion on the hazards and risks.In the right hands, they are a practical and easy to use tool, which can help most organisations in most circumstances to: Risk Matrix: The Benefits & Challenges 09-06-2016įor very good reason, risk matrices have been widely promoted in risk management standards and reference books, and despite much criticism, they’ve been widely adopted by many organisations. ![]()
