title: Infrastructual user story problem
body: <p>"We need to show quotes related with the current document."</p>
  
  <p>This user story will cause many of our subsystems to get modified, and it is more or less 4-5 sprint length. Splitting it into sub stories is impossible cause the modifications has no business value. But, in the 5th sprint, there will a business value.</p>
  
  <p>What do you suggest? How are we gonna create business value, demonstrate it to our customers each sprint and also let our customers to prioritize work on each sprint?</p>
