Analytical Techniques (RCA Tools)   “Five Whys” Approach The “five whys” approach. By using this approach, root cause contributors can be identified along with the antecedent events, and potential mitigation or prevention strategies can be suggested on the basis of the answers. Once the initiating problem is specified, a consecutive series of “why” questions are…

When we perform RCA it is not unusual to come up against causal factors which show a specific relationship between the event and one or more human factors.

It is important for the reason that we should take careful steps to ensure that we have the necessary skill level and competence in the…

Multiple analysis tools are available to perform hazard analyses for each program. Ranging from the relatively simple to the complex. In general, falling into two categories: a) Event Driven – What could cause “EVENT” b) Consequence Driven – What would be the outcome from “XYZ Behaviour”   Hazard Analysis Objectives Identify hazards. To determine the…
