Process feedback. Less focus on what they’re doing, more on how they’re doing it. This is especially necessary if their process is disruptive or harmful – for example, the person on a development team who just goes ahead and implements changes without discussion or notification. Process feedback has to focus less on the process itself, and more on the harm caused. It can be tricky to offer, is generally better done via backchannels, but may have to be escalated to a group level. At the very back edge of process feedback has to be the possibility of saying “if you can’t play nice, you can’t play.”
