A more thorough explanation:

Definition: Work-in-process refers to a product that is currently being made or put together, but is not yet finished. It is also known as work-in-progress.

Example: A car that is being assembled on a factory line is an example of work-in-process. The car has not yet been completed and is still missing some parts, but it is in the process of being made.

Explanation: Work-in-process is a term used in manufacturing to describe products that are in the middle of being made. These products are not yet finished, but they are not raw materials either. They are somewhere in between. The example of a car being assembled on a factory line illustrates this concept well. The car is not yet complete, but it is also not just a pile of metal and plastic. It is in the process of being made into a finished product.
