Microtasking is a great method of managing programmers, but it's very difficult or almost impossible to switch to this new model of work from traditional full-time management. There is a list of five simple steps I would recommend you making with your team if you want to get yourself ready for microtasking in a few months or a few years. First, make sure the use GitHub. Second, make them report their weekly results in a list of completed tasks. Third, make sure their code gets into the repository via pull requests and only after code reviews. Fourth, invite external reviewers and let them submit their ideas only through tickets. Fifth, let them work remotely, from home.
