    The importance of people in Digital Transformation

    Digital transformation has become a topic of great relevance in the business world, comparable in importance to the Industrial Revolution in its time. In fact, it is considered the continuation of the history of the industrial revolutions. The first one, 1.0, was the period of mechanization, followed by 2.0, which brought the use of electricity, and 3.0, which marked the era of computing. Now, we are living the Industrial Revolution 4.0, known as the digitalization revolution, where digital transformation is the key element. This revolution is changing the way organizations operate and how people live their lives.

    The human dimension of "Lean"

    It is well-known that high competitiveness and the changing market environment require organizations to quickly adapt to changes while reducing costs and ensuring the quality of their products and services. Being competitive in this environment involves revising traditional management methods, which is why we increasingly hear about 'Lean', not only in industrial sector companies but also in the service sector. Companies implementing this methodology seek to gain in terms of competitiveness, as 'Lean' is ultimately a method that helps the company focus on achieving the strategic objectives of the business.
