Can you explain to me how someone who spends their entire day in k8s and helm charts would benefit by exploring the UX of an application through the lens of the user? Beyond a normal study, that is?
I've run every one of my companies with some form of everyone participating at a user level regularly. Either through support or using the product. Each type of role gets something out of it. A k8s engineer can achieve more understanding of their mission and connection to how their seemingly siloed activity has a real world impact while more directly product focused roles might gain actual product insight. In my experience employees who genuinely care about what the company is seeking to achieve do gain something from the experience.
If the application actually uses that k8s cluster, then you might actually want to see the real-world performance of it all instead of just aggragated response time graphs.
