The Origin of Work in Progress vs Work in Process
Both expressions came from industrial and project language, but they developed in different ways.
Work in progress appeared first in general English during the 19th century. Builders and engineers used it to describe projects that were not finished. Over time, the phrase moved into everyday language. Today people use it for writing, art, software, and personal development.
Work in process, however, came from manufacturing and accounting terminology. Factories needed a term to describe products that were still moving through the production line. Accountants then used the phrase when tracking inventory and production costs.
Because both phrases share the same words, people often assume they mean the same thing. However, their usage fields became very different, which causes confusion today.
