It was a nice problem to have: the Scrum team was performing well, but stuck on a plateau.
At each retro they’d consider what had been working well and what hadn’t, and take some actions to address the problems - but nothing moved the needle very far.
Then the Scrum Master (Chris) tried something new, with dramatic results. You could say it was a 14-fold increase in Agility, in that they went from getting customer/stakeholder feedback once a fortnight to at least 7 times per week. Customers and sales people were delighted to be getting software that really met their needs much more quickly, and relationships improved all around.
