The market growth of printing industry in Indonesia is followed by the emerging of new companies in this business. This phenomenon forces Ref Graphika, as incumbcnts in a middle-size company in Jakarta, to create strategy that not only to make them survive, but also to gain more pieoes of the market cake. In 2006, the company applies new strategy in the marketing section to focus on the targeted markets that still grow. Those new market are corporate and publisher. Apparently, the strategic changes that the company’s brought in 2006 somehow are not only increase their profit, but also increase its cost, especially in outsourcing cost This company is outsourcing some of their processes to the suppliers. One way to decrease the outsourcing cost is by recalculating the possibility of this process to outsource or to insource.
