A market research institute determines that 80% of all newly introduced products flop in a certain branch. But even when the decision to mass produce a new product is based on the results of a test market, mistakes happen. From past experience, we know that 70% of successful products performed well in the test market. In 20% of cases, they performed mediocrely, and in 10% of cases they performed poorly. With flops, it’s exactly the opposite.
