Introducing work-in-progress limits
In January this year, we (the NET-A-PORTER GROUP Product Management team) introduced work-in-progress limits to our software development process. For example, we have at most five items “in development” (including in code review) and four “in test”. An item in this case is a user story, bug fix or investigation task.
We added the work-in-progress limits as part of a Kanban-inspired move away from a fixed-iteration process to a continuous flow of work.
