A cause-and-effect analysis generates hypotheses
about possible causes(reasons) and effects(results) of problems
·
A Cause & Effect Chain (CEC) analysis
diagram is a structured way of expressing hypothesis about the causes of a
problem or about why something is not happening as desired

It helps to focus attention on the process where
a problem is occurring and to allow for constructive use of facts to narrow

·
It cannot replace empirical testing of these
hypotheses, it does not tell which is the root cause, but rather the
possibilities
