In this chapter, we will talk about the importance of investigation in organizational learning processes. We will understand how an investigation, familiar to us from the military world, can be used as a powerful tool for improving processes, learning from successes and failures, and even strengthening the culture of learning in the organization. We will discuss the prominent advantages of an investigation, such as identifying weak and strong points, developing effective methods of action, and creating preparedness for unexpected events. #organizational_learning #Learning_Lessons #performance_improvement
