Jack Welch
LIE-D "Pioneer" 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.
Leading Function-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.
Creative Function+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.
Vulnerable Function 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.
Vulnerable Function 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.
Quadra / Temperament / Club
Quadra: 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.
Temperament: 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."
Club: 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.
Worldview & Attitude
"Organisations must be continuously transformed or they decay" — structural danger awareness. Trust in competitive efficiency as the foundation.
Attitude toward Change: Executing GE's transformation as a realistic plan — a practitioner of staged, failure-resistant change.
