"Market intelligence can never be the goal, it's always 'just' a supporting tool for decision making, strategy creation, go-to-market decisions, product development and/or setting clear targets".
Market knowledge is never static, but always subjected to continuous change and improvement. Decision should be based on a mixture of several ingredients such as market knowledge, a serious dose of realism, momentum, information reliability, experience and specially common sense.
“Information in the absence of execution is overhead!”
