A problem can be defined as anything that is not going as
per plan, per schedule or as it is expected to. We perform Root cause analysis
for understanding the root causes of the problem and try to give a solution to
the problem. It should be noted that Root Cause Analysis is not only used for
problem solving, rather it can also be used for continuous process improvement.
It can be also used for tracking and investigating. In some scenarios Root
cause analysis is also used for measuring and reporting.
We have various Root cause analysis tools available: Viz. 5
Whys, Barrier Analysis, Change Analysis, Failure mode and effect analysis, Fishbone
diagram, Pareto Analysis and Fault Tree Analysis. We have discussed the Fish
bone diagram in detail with an example.
