Jack Welch
LIE-D "開拓者" CEO · American · 20th c.Former CEO of GE (General Electric) (1935–2020). Called "the greatest manager of the 20th century" — his "vitality curve" (annual bottom-10% firing) and portfolio strategy grew GE into one of the world's most valuable companies. His methods were widely imitated and widely criticised — particularly his shareholder-value primacy, which critics blame for short-termism in American management.
主導機能-Te-p (Optimization & Ingenuity)
"Fix, sell, or close" as three options, combined with annual firing of the bottom 10% (rank and yank) — thorough management optimisation as the core of -Te-p action. Growing GE from $12B to $410B market cap over 20 years from his 1981 appointment.
創造機能+Ni-c (Future & Challenge)
"Every business must be #1 or #2 in its industry or be sold or closed" — an irrational selection-and-concentration declaration executed immediately upon appointment. "Bureaucracy will lose competitive advantage in the information age" as a 1980s insight that proved prescient.
脆弱機能1-Si-p weak (Sensibility & Subtlety)
Weak -Si-p: publicly declaring shareholder value maximisation as the top management priority over factory workers' welfare. "I'd like to put the factory on a barge and ship it to India" — cost optimisation with no sensory consideration of workers' comfort.
脆弱機能2+Fe-c weak (Elation & Revelation)
Weak +Fe-c: consciously declaring "promote people with positive energy" but this is a supplementary action for the vulnerable function — actual management centred on fear and competition. Annual bottom-10% firing as evidence.
クアドラ・気質・クラブ
クアドラ: Gamma Quadra (Market) — thorough loyalty to market principles: competition, efficiency, shareholder value. "Destroying the concept of company loyalty" — shifting from long-term employment to performance-based management as γ competitive value.
気質: Linear-Assertive temperament: synonymous with "brutal candour" — nicknamed "Neutron Jack." Publicly declaring and executing annual bottom-10% firing; returning criticism with "that is honest management."
クラブ: Researcher Club: absorbing management engineering, quality control (Six Sigma), finance, and media industry for combat deployment as the Researcher Club practitioner. Engineering background expanded into finance, broadcasting, and medical devices.
世界観・変化への態度
"Organisations must be continuously transformed or they decay" — structural danger awareness. Trust in competitive efficiency as the foundation.
変化への態度: Executing GE's transformation as a realistic plan — a practitioner of staged, failure-resistant change.
