What a pipeline is before you count them
A single pipeline
A single pipeline is one ordered set of stages that every deal passes through. Every card on the board means the same thing at the same stage, so the board can be read at a glance and conversion between stages is directly comparable across the whole business.
Multiple pipelines
Multiple pipelines are separate stage sets for genuinely different sales motions. New business, renewals and channel partner deals do not share milestones, so forcing them onto one board makes every stage name a compromise. Each pipeline gets its own stages, its own conversion maths and usually its own owner.
