Kendra wrote a nice piece on this the other day, and I agree.
The data that comes out of this helps to influence executives and managers. You can show them results, which might get them to help you change your job.
This is also a way that we can share information with each other. Are others doing their jobs better than you? Can they actually get code tested and reliably deployed? Are most people using VCS?
Or maybe not.
Share some information and learn something back. The results will be available online, and you can use them however you like to convince your organization to make changes.
We don’t manipulate the data, and we’ve hired a company that specializes in doing this, so we can try and get accurate accounting of the data.
