I knew an entire custom manufacturing company with 40 employees run with one main engineer, who worked 50-60 hours to complete his work so the employees in the shop could run the machines and do assembly. He died one day suddenly at 50 years old. He had been the sole engineer for 10 years. A week later I was training his replacement on how to use the PM tool I provide for his company. Same office, same chair.
