The book “The Human Factor: Successful Projects and Teams” by Tom DeMarco and Timothy Lister is a translation of the 2nd edition of the world-famous bestseller about managing software development projects. The first edition contained revolutionary ideas at the time (1987) that have stood the test of time. The authors have adjusted their conclusions and added several new chapters. The value of this book is that it describes principles, each of which has a real story behind it. All chapters contain observations and innovative approaches that will challenge readers and leaders to see important issues in new, smarter ways. With humor and wisdom gained from years of leadership and consulting, DeMarco and Lister demonstrate that the biggest problems in software development are human, not technical, in nature. They don't give simple answers, but they do give correct answers, backed by scientific research. The publication is intended primarily for project managers, but will also be useful for ordinary programmers.
