In the 1990s, Prоcter & Gаmble set оut tо develop а better floor-cleаning soap. Early focus groups actually rejected the initial concept sketches. The real breakthrough came when researchers visited a customer's home and asked what she wanted in a new soap. Instead of answering, she led them to a closet full of mops, brooms, and buckets, and told them a better soap wouldn't fix her real problem. That direct observation revealed customers didn't want a better soap at all; they wanted an entirely different kind of tool. This insight led to the Swiffer, launched in 1999, which has sold billions of dollars in product since. P&G's team discovered, through direct observation, that customers didn't want a better floor soap -- they wanted an entirely different kind of tool. This discovery process is best described as:
