Every PM has a lot to tell you about different fuck-ups on his projects. But why we share our fails so rarely? Of course, it is difficult to tell others about your failures, so we prefer to tell only funny stories or “one of my friends…”. We with my colleagues suggested to create the list of most common problems on our projects. I can’t hope it contains some new and fresh ideas but al least it should persuade you that you are not lonely in this world of failures.
