In Memory of a Mentor – RIP Geary A. Rummler

Geary A. Rummler

… was one of my key mentors early in my career – starting in week 1 back in 1979 when asked to read several of his articles.

Then I met him at a conference in 1980. And then I worked alongside him – carrying his pencils as the joke went – back in 1981-1982 at Motorola.

We then collaborated on several consulting gigs with several F500 clients and with our professional home, NSPI, now ISPI.
