There is a subtle change that I would like to see in the Scrum Guide. The word requirement to describe the Product Backlog has been removed. However there is still one part in the Scrum Guide that makes the team think the Product Backlog is a fixed requirement.
I would like this part in the Product Backlog section
The Product Backlog is an emergent, ordered list of what is needed to improve the product.
to be changed to:
The Product Backlog is an emergent, ordered list of what might be needed to improve the product.
If the items in the Product Backlog are emergent, I think what is needed to improve the product is unclear even before the development start. By changing this part, it should encourage the Scrum team to
- Evaluate if what they have in the Product Backlog is still needed;
- If it is no longer needed then it should be removed from the Product Backlog;
- And also not to overthink or overly detailed all of the Product Backlog items upfront;
