The complexity of economic activities, in conditions of competition imposed by the market economy leads to the increase in the role of economic and financial information in decision-making process. The quality of information depends on the quality of current decisions, decisions made on long term and the results expected by the company. In an environment where ordinary standard product gives way to what some call "Product-service", cost analysis requires more refinement, focusing on service and quality characteristics associated to products. The concept of activity came to the fore in recent years. Controlling costs and performance must be achieved through performance acknowledgment by people who are capable of making important decisions. In addition, management accounting seems to be ideal for remote "Pilotage".
