The problem with most SaaS pipelines is the definition of a stage
Ask a team what their demo stage means and you usually hear that a demo was delivered. That is a description of what the seller did. It says nothing about whether anyone on the buyer's side intends to proceed, which is the only question the pipeline exists to answer.
A stage should advance on buyer evidence. The buyer confirmed a timeline. The buyer involved security. The buyer reached an activation event in the product. The buyer agreed to a mutual plan with dates. Each of those can be checked by someone who was not in the room, and a pipeline built from them forecasts far better than one built from seller effort.
