Pipeline
also called sales pipeline
The set of open opportunities and the stage each has reached.
Everything in progress, by stage.
What It Is
You will find Pipeline in the Marketing layer, alongside the rest of Channels. The canonical meaning is the set of open opportunities and the stage each has reached.
It is a label with a settled working definition, so the value is in using it the same way every time. Once it is defined that clearly, arguments about it usually stop.
How It's Used
Pipeline earns its keep in campaign planning, channel choices and the reporting that follows them. It normally appears alongside Customer Relationship Management, Lead and Qualification. The practical test is whether everyone in the room means the same thing by it.
Why It Matters
The cost of being vague about Pipeline shows up later, not today. When it is unclear, spend keeps moving but nobody can say what it bought. Clarity here removes a surprising amount of downstream argument.
Picture a word everyone in the room has agreed to use the same way. Everything in progress, by stage.
Termshift™
How the meaning shifts depending on who is using it, and where.
Professionally, Pipeline carries the narrow meaning: the set of open opportunities and the stage each has reached.
Explained to someone with no marketing background, Pipeline is everything in progress, by stage.
The Bottom Line
If you only keep one thing about Pipeline: everything in progress, by stage. Everything after that is detail.
