Tomada de decisão em investimentos industriais: estudo de casos múltiplos

Abstract

This thesis deals with the relationship between the adoption of different models, based on cost concepts, costing principles and methods, and the investment decision-making process in industrial companies. As a reference for addressing the subject at hand, a set of publications that deal with the subject were studied and critically evaluated, covering conceptual elements such as: the firm's economy and the strategic environment, models and decision-making, cost models and, finally, investment models. The method selected to conduct the research was the Multiple Case Study, having been chosen, elaborated and described two investment cases. In addition, nine interviews were conducted with professionals internal to the company, market professionals and academics. Based simultaneously on the theoretical framework and the analysis and critical synthesis of the interviews, an investment analysis framework was designed. Based on this framework, a Decision-Making Method for Industrial Investments was constructed. From an academic point of view, the main contribution of the thesis was to clarify and highlight the importance of costing principles and their influence on mental models in decision-making, emphasizing the need to consider only relevant costs when constructing investment analysis models. In addition, it emphasizes the relevance of qualitative elements and models and methods for more accurate, integrated and systemic decisions. From a managerial point of view, the study resulted in the construction of a Decision-Making Method for Industrial Investments, with steps that make the decision-making process more assertive and effective.
