The best way to do this is for improvement community members to work side by side with development team members on something important to the development team. This is what Google’s “test mercenaries” do. Test mercenaries are members of the testing community who are experienced engineers with a passion for and expertise in testing. They spend up to 20% of their time for three months on a project other than their own. During this time they add tests and refactor code as a direct help to the development team.
