A lot of development teams typically have a “In Test” column on their boards to indicate when things are being tested. Some even have “Waiting for Test” columns this way the Test team know what work to pick up next and are never left idle. This also allows the Dev team to keep busy while Testers are verifying the system is fit for purpose. Which all seems like a good idea but what a lot of teams don’t realise is this is actually leading them to have more work in progress rather than focusing on finishing work.
In this talk I’ll explain why the “In Test” column causes these problems, how to apply the Theory of Constraints to solve them and how you can use the same approach to other processes too.
