We are a software testing team that uses Kanban for visualizing our work. In our backlog we have both work items related to the work of testing but also the work of preparing and maintaining test systems, computers, lab etc.
Our backlog is huge at the moment and it is hard to see how work items connects to larger initiatives. Let's say we have a new feature to test. We create a test plan, a word document, and put everything in that related to the test of the feature. Then we create work items in the backlog for planning, configuring, preparing test systems, creating test cases, executing tests etc.
But it's very hard to see the connection between the work items and what part their playing in the bigger picture of the feature testing.
Are there anyway recommended ways to handle this?
