I'm trying to apply Jira's Kanban to our development team to make our work more manageable and predictable. The development team consists of three backend Java developers and one tester. The developers implent new features, write unit tests, fix bugs. A tester performs manual testing and new writes tests. We came up with the following workflow: READY_FOR_DEVELOPMENT, DEVELOPMENT, CODE_REVIEW, TESTING, DONE.
But it never happens that we have a large amount (or zero) of tasks in one column. I don't feel like this board is helping us in any way.
Maybe the steps we have chosen for our wolrkflow are too trivial? What Kanban workflow have you used in development teams (consisting of developers and testers)? How did it help your team?
