Conclusion Indrajit Das;REC;IIT-KGP

Indrajit Das;REC;IIT-KGP Merits De-merits 1. Helpful when confronting hazards that are difficult to quantify - Hazards rooted in human performance and behaviours - Hazards that are difficult to detect, analyse, isolate, count, predict, etc. -Methodology doesn’t force you to explicitly rate or measure deviation probability of occurrence, severity of impact, or ability to detect 2. Built-in brainstorming methodology 3.Systematic & comprehensive methodology 4. More simple and intuitive than other commonly used risk management tools 1. No means to assess hazards involving interactions between different parts of a system or process 2.No risk ranking or prioritization capability --Teams may optionally build-in such capability as required 3.No means to assess effectiveness of existing or proposed controls (safeguards) --- May need to interface HAZOP with other risk management tools for this purpose
