Given the need to study di erent areas of analysis during the investment decision process, it is imperative to know which tools and methods are used by companies to assess various financial and non- financial aspects. As regards tools, we find that fi rms use checklists of analysis for non- financial aspects, whereas they use their past experience in risk assessment, gathered from other projects. Records of past evaluation tend to be maintained in companies and those that use external advisors to evaluate projects tend to perform political analysis. As for the methods, companies use the identi cation of risk factors and assessment of eff ects and risk probabilities, the discussion and assessment of favorable and unfavorable factors to the project's execution, a coordinated analysis of nancial and non- nancial aspects, and the creation of lists of risk indices, attributing a qualitative weight to each item. We have also analyzed the relationship between these tools and methods and each area of analysis in project evaluation.
