Hey! Loved the article. I am currently employed as a scrum master in a scrum environment. About your proposed "fix" to management: even with the light pairing you recommend, wouldn't kanban eventually cause siloing? Even using scrum at my job, we have individuals becoming the "Feature X" guy or the "Feature Y" guy. This person then essentially disappears into a hole perfecting that one feature for weeks/months, even if there are more pressing/interesting matters. I don't see how kanban wouldn't increase that even more. Also, how do you estimate? Individual or group? Does everyone on the team possess the skills to estimate every story?
