highly structured selling process pioneered by the US Rank Xerox photocopier sales organization during the 1960's, and adopted by countless business-to-business sales organizations, normally as the ' Seven Steps of the Sale', ever since. PSS places a huge reliance on presentation, overcoming objections and umpteen different closes. Largely now superseded by more modern 'Open Plan' two-way processes, but PSS is still in use and being trained, particularly in old-fashioned paternalistic company cultures. The regimented one-way manipulative style of PSS nowadays leaves most modern buyers completely cold, but strip it away to the bare process and it's better than no process at all.
