We have a Kanban approach as our engineering process is too "fluent" to be completely railroaded and controlled by Scrum. Even with Kanban, it can happen that small tasks come and get handled even before they appear on the planning/kanban board. Sometimes they are relevant to the engineering process so I want to add them, even if they are already done.
I'm perfectly fine with tasks having different 'sizes', but I wonder what a good approach is to add tasks that I can basically immedeately file as "done."
Looking forward to you experiences with this.
