"Managerial accounting is part of a dynamic business world. A companys business strategy will change over time, often due to external factors such as technology changes, market competition, and government regulation. The companys organizational structure (the 3-legged stool) will change with a change in business strategy. Likewise, the internal accounting system will change with a change in organizational structure. Before implementing an accounting system or other organizational change, it is important to understand what is driving the change. Changes in the accounting system rarely occur in a vacuum. Accounting system changes generally occur at the same time as changes in the firm's business strategy and other organizational changes, particularly with regard to the partitioning of decision rights and the performance evaluation and reward systems. An accounting system should not be changed without concurrent, consistent changes in the way decision rights are partitioned as well as in the performance reward systems. All three parts of the organization's structure must be internally consistent and coordinated. An accounting system should NOT be adopted merely because other firms are doing so; they may have different external factors driving their changes. An accounting system should not be changed without solid ethical and professional reasoning behind the changes. Many decisions are made based on the reliability and relevance of internal accounting information changes to an accounting system should improve the usefulness of that information, otherwise, if it aint broke, dont fix it." I only need a response to this
