In closed-loop control systems, the system you seek to control is called the plant. The estimator seeks to understand what the plant is doing, and the controller influences the plant based on information from the estimator. Read, write, check, repeat.
As a team leader, your team is your plant. You are the estimator and the controller.
What kind of estimator do you want to be? …a listener? …a thinker? …compassionate? …thoughtful?
Without those critical qualities, how well can you expect to lead? What would you call a controller with no estimator, no gauge on how the team of humans (the plant) is really doing? Mindless.
