The project team is slogging through an invisible morass and its bus factor (https://goo.gl/68Lis6) is approaching zero (critical information is lost even though no one left the team). If this seems familiar to you, you may be suffering from the effects of poor documentation whether you know it or not. You can prevent this scourge, but getting your team to invest in documentation may not be easy. Come to this session and find out how to sell the value of good docs and how to produce them. Avoid dead documentation just as you would dead code, by understanding what to include, what to leave out, and how to create living documentation that never goes stale. Practical techniques based on real world experience will be presented, with plenty of examples. Start raising your project's bus factor today.
