e/Case analysis

Information
has gloss	eng: Case analysis is one of the most general and applicable methods of analytical thinking, depending only on the division of a problem, decision or situation into a sufficient number of separate cases. Analysing each such case individually may be enough to resolve the initial question. The principle of case analysis is invoked in the celebrated remark of Sherlock Holmes, to the effect that when one has eliminated the impossible, what remains must be true, however unlikely that seems.
