Here’s a quick thought that you might like to use in your next retrospective: Do you know that the software you just released has realised the expected value?
What if the answer is that you don’t know? How could you find out? And what might be the positive or negative side-effects of going to find out?
Here’s another way to look at the same question: Do you deliver more value by moving to the next story/MMF, or by helping the current story/MMF to release its full potential? Is there a single answer for your software/service? If not, what factors or conditions would cause the answer to change?
