Many excellent engineers are caught off guard and unprepared for the multiple new dimensions of responsibility required by a management role. The four streams described in this book are a simple, memorable mental model of these new dimensions of responsibility, attention to each of which is necessary to becoming a successful manager. Kudos to Mr. Cirne for his mathematical precision in reducing the complexity of an otherwise bewildering transition!
