Many people, even the people supposedly using Agile, have too much work to do. You have project work. You have support work, formal for customer support or sales, and informal for your colleagues. You have reports to write or file, time cards to fill out, or other periodic events. You know your multitasking is slowing down your work, making you crazy, and making it difficult to deliver your best work. You need a way to say no to more work.
Agile and Scrum were supposed to free us from management: self-organized, cross-functional teams who get stuff done without that old-guard hierarchy. In this fauxtopia, some software developers were more equal than others. Can we get the healthy parts back without the Lumberghs? To bring back healthy engineering management, we must first de-mystify and de-stigmatize the concept of management.
