The article discusses a method called Earned Value Management that helps estimate the final cost and completion time of a project. However, this method doesn't consider future changes that could affect the project. The researchers propose using risk management to identify potential threats and opportunities that could impact the project's performance. By combining these two methods, a new coefficient is introduced to better estimate the project's final results. This approach aims to help project managers focus on achieving their goals by accurately predicting the project's outcome.
