Companies must have total Confidence when hiring a Marketing Advisor, because otherwise, the Marketing Advisor could only work with part of the information, and with the totality as appropriate. I would only know part of the problem and not the whole, so it is obtained as a result, and misdiagnosis of the situation, and equivocal strategies. The company must make a decision when hiring a Marketing Advisor, and if you want to hire it, you must trust him and his experience 100%.
