We require environments where people can provide input and ideas. If we limit engagement, we limit success. We still have organizations who either believe or act like they believe some types of workers are “stupid.” This idea dates back to the ideas surrounding Scientific Management, Fredrick Taylor, and Henry Ford. The concept of the stupid or unskilled worker that I mentioned was common in the early 20th century. In various writings about agile and agile ideas, we often refer to or see references to avoiding Scientific Management, Classic Scientific Management, or Taylorism. These management ideas limit engagement from people, which is going to limit success.
Understanding the past can be quite helpful to see where you might be able to improve today.
