Integração do método do custeio variável à demonstração financeira de resultados: um estudo de caso em uma indústria de médio porte.

Abstract

This research deals with the conflicting differences among the diverse costing methods presented by the literature in management accounting and production management, focusing on the question of the understanding conflicts which are created between the "accounting world" and the "production management world" since the figures presented and analyzed by both are usually disparate. Such conflicts may sometimes drive to a poor management, with reflex many times in inadequate short term decision making. The research has as main objective to integrate the management method of variable costing to the financial statement without impairing the aggregated results. It is proposed for it the utilization of a hybrid model of analysis that presents at the same time the results determined from management criteria of direct costing and the results determined from the financial accounting, based on absorption costing. As secondary objectives it pursues to evidence the theoretical aspects that define the conflicts and limits which permeate the costing topic when put under the management accounting and the financial accounting perspectives and to raise specialized literature about costing methods, identifying their main differences. Thus, it is performed a general revision on the literature related to systems, methods and tools for costing and economic production management, aiming at providing a general framework that delineates the mentioned context, including, but not limiting to, the questions that permeate the subject. The research is constructed and based on a case study with qualitative approach, where it seeks to capture, besides the numeric differences question, the nuances of managing and understanding the results experienced by a real company. It provides an integrated view of the costing process that enlightens both the management decision making and the impacts caused in final aggregated results from financial accounting.
