The cost strategic management methods can be classified as cost strategy formulation methods and implementation methods according to the strategic cost management process; and the cost strategy implementation methods are divided into strategy implementation basis confirmation method, organizational implementation method, supervision (surveillance) and variance (performance) analysis & adjustment method according to the contents to be implemented.展开更多
