Documentation
Just got off the phone with the owner of a technology outsourcing company I use to work for. Their client is suing the company for more than half a million dollars for a web application they developed because it did not meet specifications.
It was almost a year long project with plenty of scope creep and rolling change requests, and because everyone was so anxious to get the product out the door, no one documented properly. Now they’re fighting a legal battle with insufficient documentation to prove what requirements everyone agreed too.
The thing that scares me is that their documentation was better than most companies I’ve worked for.
