In these times where we are paying the heavy price of move fast and break things, I think we need to move slower, not faster.
I am not a fan of sprints EXCEPT as a way to do ideation. Design thinking is a mindset, not a methodology (no matter what IDEO says, there is previous work that shows you become a design thinker by doing years of design.)
What we need now is good, vigorous Interaction Design and Information Architecture. Let's bring back slow and cautious. Let's start acting like real engineers who earn their iron band and know better than to subject the humans who depend on them to their whims.
