Finance ✦ Penny’s Take
Total Productivity Management (TPmgt)
David J. Sumanth · 1997
64/100
👎 Skip It
Sumanth built a genuinely comprehensive framework here, and it's been taught in university programs in over 50 countries, so the substance is real. But it's dense, technical, and nearly 30 years old now, which makes it a tough sit for anyone outside an industrial-engineering classroom. Respect it as an academic reference, not casual reading.
