| Ideally, an agile document is just barely good enough, or just barely sufficient, for the situation at hand.

| In this fourth and final part of the series I'll share some of my advice for writing good specs.
The biggest complaint you'll hear from teams that do write specs is that "nobody reads them." When nobody reads specs, the people who write them tend to get a little bit cynical. It's like the old Dilbert cartoon in which engineers use stacks of 4-inc... |
