A Kanban development team has a WIP limit of 4 on their in-dev column.
One of the team members is part-time i.e. not 100% and they are working on a story and therefore holding up 1 spot in the WIP dev column. The team member has many other responsibilities so is not 100% focused on this story.
Should we remove the team member and create a kanban board specifically for them to manage all their tasks or what is a good solution?
