The usual failure
Stages are labels copied from a template. 'Won' is a feeling. Lost reasons are optional. Reporting is a screenshot someone does not believe.
What to make true
Every stage has an exit rule. Owners are unambiguous. Lost is captured. A new hire can explain a contact in thirty seconds.
Worked example
Keep it this plain. A team uses pipeline as if buying the software installed the meaning. It did not. Stages are labels copied from a template. 'Won' is a feeling. Lost reasons are optional. Reporting is a screenshot someone does not believe. The move is not a new integration. Every stage has an exit rule. Owners are unambiguous. Lost is captured. A new hire can explain a contact in thirty seconds.
