What does rationalisation mean?
Rationalisation is the process or result of making something logical, efficient, or defensible through careful reasoning. It can refer to simplifying a system, reorganizing resources, or explaining a decision in terms of sound principles rather than personal or political motives. In business and public administration, the word often denotes a programme intended to cut costs, streamline procedures, or improve performance. It can also have a mildly critical use when an explanation appears designed to excuse a questionable decision. The term is common in British English, while American English generally uses the spelling rationalization. Because rationalisation can describe both a rigorous analytical process and an institutional effort to make limited resources work harder, it combines ideas of logic, efficiency, and justification.
nounThe process of making something reasonable, efficient, or based on logical principles. It may also mean an explanation or reinterpretation of an action or belief as rational.
- The process of making something logical, efficient, or based on rational principles.

In business writing, rationalisation can sound reassuring while concealing painful cuts: the process may be rational, but its human consequences need not be.

Where does rationalisation come from?
The word was formed in the 19th century from rational together with the suffix -isation, meaning the process of making or becoming something. Rational comes through French from Latin rationalis, a derivative of ratio, meaning reason or relationship. The same Latin root also underlies rationale and ratio.
