Bad estimates: You don't know what you don't know. You don't know how much time it will take to do something you never have done. Problems are dam hard: What we do is really hard, so basically we have to trim our projects to the basics, instead of doing what we want to do, which is way more. Creative people want to start-create always way more projects that what they could finish, so we need discipline here. *Complexity and lack of documentation. Another thing that needs a lot of discipline. People believe that what they know after thinking on it for a lot of time is evident for everybody else. It is not. Not only that, people forget what they know today if they do not document it, so if you do not document a year from now you will repeating most of your work, with the company's budget.
