On average what do you accomplish in a day / week / month / year?

Back when I coded as part of a team, we'd produce some 40K lines of professional code a year. Some days, nothing. Some days - lots of progress.

Progress for a Software Engineer isn't just code. For every month coding, there are 11 spent debugging, documenting, testing, integrating, shipping, supporting.

Further there are stages of code: program, project, product. It matures thru these stages as documentation and support develop.
