Strategy: Maslow pyramid

Maslow's pyramid identifies the products required by customer needs. It is a theory in psychology that Abraham Maslow proposed in his 1943 paper A Theory of Human Motivation, which he subsequently extended. His theory contends that as humans meet 'basic needs', they seek to satisfy successively 'higher needs' that occupy a set hierarchy.
Maslow's pyramid is often depicted as a pyramid consisting of five levels: the four lower levels are grouped together as deficiency needs associated with physiological needs, while the top level is termed growth needs associated with psychological needs.
