Which two criteria are useful in deciding if something should be documented every sprint?
- A. It has always been documented in the past
- B. It is required by the definition of done
- C. The software tool being used requires it
- D. The documentation is used to enhance and maintain the software
- E. The scrum master demands it
Answer: B,D
Explanation:
if the documentation is adding to the quality and maintenance of the software this is definitely a good argument for documenting every sprint.

If the company's definition of done says so, you must :)
