Root cause analysis


 

Root cause analysis is the process of learning from consequences. The consequences can be desirable, but most root cause analysis deals with adverse consequences, e.g., the so-called d-words: death, damage, delay, disruption, dollars (of loss), disgrace, discredit, discharges (to the environment), etc.

  • Do all reasoning from solid evidence.
  • Determine what influenced the consequences, i.e., determine the necessary and sufficient influences that explain the nature and the magnitude of the consequences.
  • Establish tightly linked chains of influence.
  • At every level of analysis determine the necessary and sufficient influences.
  • Whenever feasible drill down to root causes.
  • There are always multiple root causes.

  • Define the Problem: What do we want to prevent from recurring? When and where did it occur? What is the significance of the problem?
  • Analyze Cause and Effect Relationships: Once the problem is defined, we need to understand the causes and how they interact with one another.
  • Identify Solutions: Solutions are specific actions that control causes.
  • Implement the Best Solutions: The best solutions are those that prevent problem recurrence, are within our control, and meet our goals and objectives.
