Delivery Pipeline Step 2: Write the Backlog
Turn your project's remaining work into user stories, each with a 'so that' clause you can genuinely complete. Split anything that would take more than two days, splitting so each piece still delivers something usable. Write acceptance criteria for the top five. Then write your definition of done, once, and put it where you will see it. Finally, look for any story whose 'so that' you could not write, and either find the reason or delete the story.
