Choosing between work in progress vs work in process can be confusing because both phrases describe something that is not finished. In many cases, people even use them as synonyms.
For most everyday writing, work in progress is the better choice when you mean that a project, task, essay, design, or other piece of work is still being completed. Oxford defines work in progress as a project that is not yet finished and is still being developed.
Work in process also has a real meaning. It is especially common in manufacturing, accounting, and production. It can describe goods that have started production but are not yet finished.
This difference is useful when you write emails, reports, school work, business documents, or project updates. You will also see both phrases shortened to WIP, depending on the context.
Below, you will learn when to use each phrase, what they mean, how they differ, common mistakes, and simple examples.
Work in Progress vs Work in Process – Quick Answer
Work in process can have the same general meaning, but it is often used in manufacturing, production, and accounting for partially finished goods.
Simple rule
- Work in progress = an unfinished project, task, essay, idea, or piece of work.
- Work in process = unfinished work, especially goods or tasks moving through a production process.
For example:
My website is still a work in progress.
The factory has a large amount of work-in-process inventory.
If you are talking about a normal project or something you are still improving, work in progress is usually the clearest choice.
What Does Work in Progress Mean?
Work in progress means something has started but is not finished.
It can describe many kinds of work:
- A school essay
- A website
- A painting
- A building project
- A book
- A business plan
- A personal skill
- A software project
Oxford gives the example of an essay that is still a work in progress.

The products have started production. They still need more work before they become finished goods.
In accounting, work in process can also refer to the costs tied to unfinished goods, including materials, labor, and factory costs.

Work in Progress vs Work in Process in Simple English
Think about the two words progress and process.
Progress focuses on moving toward completion.
The project is making progress.
Process focuses on the steps used to complete something.
The product is going through a process.
This gives you a useful memory trick:
Project → Work in progress
Production → Work in process
This is not an absolute grammar rule, but it is a helpful guide for everyday use.
Origin and History
The two phrases developed from common English words.
Progress comes from the idea of moving forward or moving toward a goal. In work in progress, the focus is on work that is moving toward completion.
Process refers to a series of actions or steps used to produce a result. In work in process, the focus can be on work moving through those steps.
Modern business and manufacturing language uses work in process as a term for unfinished goods. At the same time, work in progress has a broad everyday meaning for unfinished work.
Both phrases are also abbreviated as WIP in different contexts. Collins lists WIP as work in progress in British English and both work in process and work in progress in American English. )
British English vs American English
There is a usage difference worth knowing.
Work in progress is widely used in both British and American English for something unfinished.
Work in process is also used in American English, especially in business, manufacturing, and accounting.
Collins lists WIP as work in progress in British English. For American English, it lists both work in process and work in progress. )
However, this does not mean that British speakers never use work in process, or that Americans only use work in process. The meaning and field matter.
Examples
General English:

Manufacturing:

So, there is no simple rule that says one phrase belongs only to Britain and the other only to America.
