Is funny to hear people feeling that documentation is not required as per scrum. How often have I heard this thing? I was once involved with tool development for sun microsystems. The scrum master and product owners then choose not to create stories with this comment. I could quote one more instance where in an mm it was a question in scrum master all hands that teams spend a lot of time in writing documentations like high level design, low level design, customs documentation etc and this is against lean principles.
Hey guys hold on! Can you spot which mean principle tells you that lean is against documentation? Lean is about delivering value. Systematically identify activities which don't add value and eliminate them to enhance profitability in long term.
Ask yourself if a particular piece of documentation ads value? If yes, lean is never against it.
