The analysis has also been focused on the company's attitude to overcome the financial crisis. Secondly, the authors have analyzed if the recovery project has required the introduction of a new management control system or changes to the existing management control system. The methodology is composed of several steps. First of all, the authors have analyzed the existing literature. Secondly, the authors have referred to a sample of 98 Italian recovery projects formalized by Italian private companies. The analysis of the literature and the recovery projects permits to achieve some provisional results, which have been tested through surveys. The methodology approach is inspired by the grounded theory. The findings have been several: (1) The crisis is a usual event in the lifecycle of a firm, due to a deterioration of its strength and a change of the context; (2) The timing factor has played a fundamental role in managing the crisis situation, because a late identification of the symptoms or a minimization of them can generate an irreversible situation; and (3) In addition, a recovery project includes the introduction of a new management control system or changes to the existing management control system. These new or modified management control systems use "feed-forward" mechanisms, which make early predictions about the changes in the characteristics of the competitive framework. 展开更多
