1) We do need better awareness of what others around us are doing, especially across the dev/ops divide. 2) Communication, kanban is there to show interested non-devs how projects are progressing.
We update the kanban before the meeting and let one person per day read through the entire board for today/ongoing/blocked. If there are any tasks that person doesn't understand – this is the time to ask.
The process takes often less than 10 mins per day.
Any issues raised will be discussed in loosely formed groups afterwards to not waste everyone's time.
I think what I learned is that you mustn't let process be shoved on you by middle management. Take control to make these things productive for you.
