It has been long-established that traditional costing systems are inadequate and therefore managerial accounting has been transformed to include strategic elements and consequently it helps managers to strategically manage their business. Today, costs need to be controlled in terms of long-term development because the short to medium-term view which has been applied to date has ceased to be sufficient. What has caused the previous traditional management accounting systems failed? With the advent of new technologies, products are no longer burdened by direct labor as they did before, and the share of overhead costs on a product has changed to a completely opposite position [14]. Previously, direct labour and other direct costs accounted for a large part of product costs while overhead costs accounted for a small component as compared to the current situation. Today, a major share of the product is represented by overhead costs, and direct costs no longer constitute the dominant position as before.
