As I read the original post, it does not ask for a definition of design output:
"What constitutes Design Input?"
"What is the difference between "requirements" and "specifications"?
I must add that people who study these things will tell you that definition by example is the least useful form of definition. It is the difference between someone asking "What is a fruit?" and being told that it is the "edible reproductive body of a seed plant, especially one having a sweet pulp associated with the seed" and "things like apples, oranges, and pears." The latter is of limited value to someone who doesn't already know what a fruit is, since it enables them to recognize only apples, oranges, and pears as fruits. It tells them nothing about why these items are fruits, or how to identify other fruits as fruits. It does not contribute to an understanding what a fruit is. As I read the question, tantan seeks understanding.
