Work In Progress is a term used to describe unfinished work. This can be code, documentation, testing, etc.
Use cases and Examples
You will find the term used as a label usually in its short-form WIP in places where other developers can see the work of their colleagues.
One of such popular places is in GIT messages. The message lets others know the code or document is still being worked on and might not work or should not be touched.
