Dassault Systemes is heavly into "PLM" -- short for "product lifecycle management." Who was the first to use the phrase? Let's look at the press release record:
Dassault's press release archive goes back to 1996. The earliest date for one of their press releases including the terms "PLM" or "product lifecycle management" is June, 2000.
Over at the SAP.com press release archive, the earliest mention of PLM is in a press release dated February, 2000: "SAP PLM is available via a flexible, role-based licensing model with mySAP.com Edition 1 Update December 1999."
So we know the term was in use in December, 1999. Anyone have an earlier date?
