In Progress vs In Process: What’s the Difference?

Quick answer: “In progress” is the standard, widely accepted phrase meaning something is currently happening or underway, as in “the project is in progress.” “In process” is used less often and usually appears in more technical or formal contexts, such as manufacturing or legal procedure. For everyday writing, “in progress” is the safer, more natural choice.

What does “in progress” mean?

“In progress” means something has started and is actively moving forward but is not yet complete. It is the standard, everyday phrase used across business, casual and formal writing alike.

You will see it constantly: “Your download is in progress,” “The renovation is in progress,” “Negotiations are in progress.” It works smoothly in almost any context where something is underway, which is why it’s the safer default choice for most writers.

What does “in process” mean?

“In process” means something is currently moving through a defined set of steps or stages, often within a formal or technical system. It appears less frequently than “in progress” and tends to show up in specific fields.

For example, in manufacturing, “work-in-process” (sometimes “work-in-progress” is used loosely instead) refers to partially completed goods on the production line. In government or legal contexts, “your application is in process” suggests it is moving through an official, multi-step procedure, not just happening casually.

In Progress vs In Process: Which One Should You Use?

For general, everyday writing, “in progress” is almost always the better choice. It is more widely recognized, sounds natural in casual and professional contexts alike, and rarely raises questions about tone.

Reach for “in process” mainly when referring to a formal, defined procedure, such as a manufacturing stage, a legal filing moving through a system, or specific industry terminology where “in process” is the established convention. Outside those specific contexts, “in progress” is the more natural fit.

Is “Work-in-Process” the Same as “Work-in-Progress”?

They sound alike but serve different purposes. “Work-in-progress” (WIP) is a broad, everyday phrase for anything unfinished, from a half-written novel to an ongoing renovation.

“Work-in-process” is a more specific accounting and manufacturing term referring to partially completed inventory, goods that have entered production but haven’t yet become finished products. In casual writing, “work-in-progress” is almost always the right choice; “work-in-process” belongs mainly in inventory, accounting and operations contexts.

In Progress vs In Process: How Can You Remember Which One to Use?

Default to “in progress” unless you have a specific reason not to; it fits nearly every everyday situation. Think “progress” like “moving forward,” which matches its general, flexible meaning.

Reserve “in process” for formal procedures and defined systems, and think “process” like “a procedure with steps,” which matches its narrower, more technical use.
