When the concept of agile was first being established, a very simple set of statements was written to help define it. Of the 12 principles behind the agile manifesto, five are related to interacting with people.
Being agile means putting people first, and that includes our stakeholders, managers, coworkers, and ourselves. For me as a manager, I have a customer that my team is working for, but my employees are also my customers. In a similar manner, I am a customer of my employees, and we all need to keep each other in mind.
Several years ago, my team had made a series of small mistakes. These were relatively little things, like getting an inventory wrong, or failing to notice something in a facility, or messing up a software configuration. But when you added the half dozen or so small mistakes together, it meant that my team had produced nothing but failure for two weeks. We had been screwing up over and over again, and now my boss expected me to drop the hammer on my team.
