RankTracer - Amazon Sales Rank Tracking & Analysis

All business problems run around cost-benefit analysis. Business takes actions. Each action has cost. If it does not generate benefit greater than cost, the action need to revisit. Should cost can be reduced by finding another alternate or it does not generate any benefit? In fact several actions are taking place daily, in each moment at different places or by different person. Each action impacts cost and benefits of other actions. So final result need to be determined by coordinating and compiling such several actions. It is difficult (or imposible?) to determine cost and benefit of each action. Good manager does that. That is what good MBA curicula teach.
