If not, why bother?
Work is something which a human or machine (technology) does to affect some kind of change on our reality. That change may be something obvious (a new table has been made) or very subtle (a decision has been made). In all cases, something is made present which was not present before the work took place.
If an official product name/title does not exist for what you are working on, then it should be possible to describe what the product of your work is, in your own words.
If work has no product – think output – then the question should be raised as to whether it is valid and meaningful work to be doing.
