Why ABM Implementations Fail
ABM can fail as a system for a variety of reasons. One of the major reasons is the lack of support of higher-level management. Not only must this support be obtained before undertaking an implementations project, but it must also be maintained. Loss of support can occur if the Implementation takes too long or the expected results do not materialize. Results may not occur as expected because operating and sales managers do not have the expertise to use the new activity information. Thus, significant efforts to train and educate need to be undertaken. Advantage of the new data need to be spelled out carefully, and managers must be taught how these data can be used to increase efficiency and productivity. Resistance to change should be expected; it is not unusual for managers to receive the new cost information with skepticism. Showing how this information can enable them to be better manager should help to overcome this resistance. Involving nonfinancial managers in the planning and Implementation stages may also reduce resistance and secure the required support.
Failure to integrate the new system is another major reason for an ABM system breakdown. The probability of success is increased if the ABM system is not in competition with other improvement programs or the official accounting system. It is important to communicate the concept that ABM complements and enhances other improvement programs. Moreover, it is important that ABM be integrated to the point that activity costing outcomes are not in direct competition with the traditional accounting numbers. Managers may be tempted to continue using the traditional accounting numbers in lieu of the new data.
