Insightful, and concise article by Charles Lambdin on the trap that even successful agile teams can fall into if they do not pay attention to human centered design (UX/CX). As Henry Ford said: if I had just listened to customers, I would have designed a faster horse. Discovery Kanban and dual track scrum are attempts to address this issue.
Highly informative article and video by Patrick Steyaert regarding customer kanban aka discovery Kanban. Patrick is the originator of this concept and he explains it beautifully. This is a must-read / must-watch for all agile practitioners, regardless of your agile method of choice.
