Eliminating waste from processes, per Toyota. Also, as an adjective, the corporate word for understaffed — 'we run lean' means the person who left won't be replaced.
Heard in the wild
“We're a lean operation, which is why voicemail is a myth here.”
Tone check: Euphemism
Methodology: legitimate. Adjective: audit it. 'Lean' teams missing deadlines aren't lean; they're starved.
