Some tasks in software development are mundane such as formatting and code conventions. Where possible tooling should take away some of this pain, however sometimes you need a developer to take on a task that requires a great deal of time and/or effort to complete. Tooling will only get you so far.
An example of this would be declaring that all projects build and compile with zero warnings. I've tried this in the past after a team retrospective. We had hundreds of errors per project, covering about fifteen projects at the time. Spending several weeks of development time resolving these would not have be fun nor financially viable. However we really wanted to implement this change
- I wrote a single test which would execute as part of the build process that asserted the count of the errors per project.
- Every now and then whenever I had some slack time (10 mins before a meeting, 30 mins at the end of the day etc...) I would open up a project and fix some errors. Then run the test and try and lower the number of errors it was asserting against until I hit the lower limit.
- Rinse repeat this process and after a while a project would assert that there are no errors.
- From here on it was impossible for a developer to commit in a change that would raise a warning.
- The limit would ensure that during this period no new errors were added, increasing the work load.
After a month or so all the projects reported zero warnings. Going forward the test was modified so that new projects added to source control would be checked and have the same tests run against them, meaning no new projects can have a warning count greater than zero.
