Research-supported

Here are ideas that have research backing, but it’s not as direct and unambiguous as in the “Evidence-based” section. It may be a synthesis of adjacent data, an influential practitioner book grounded in research, or a field where consensus is still forming. The grounding is real, but with caveats.

1. Theory of Constraints

   Eliyahu M. Goldratt (with Jeff Cox) (1984) — The Goal: A Process of Ongoing Improvement

   Goldratt showed that the throughput of any system is limited by a single 'bottleneck', and that management begins with finding and relieving it.

2. Leverage points in systems

   Donella H. Meadows (1999) — Leverage Points: Places to Intervene in a System

   Meadows laid out a hierarchy of 12 places to intervene in a system — from parameters to paradigm shifts — and showed that the most powerful leverage points are usually the least obvious.

3. Full Range Leadership Model (transactional/transformational leadership, management by exception)

   Bernard M. Bass (1985) — Leadership and Performance Beyond Expectations

   Bass distinguished transactional leadership (exchange and 'management by exception') from transformational leadership, laying the basis for the modern full-range leadership model.

4. Lean Startup / MVP methodology

   Eric Ries (2011) — The Lean Startup: How Today's Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses

   Ries proposed the 'build-measure-learn' loop and the concept of the minimum viable product as a way to test business hypotheses faster and more cheaply.

5. Bus factor (knowledge concentration risk)

   Software engineering community (folk/community-originated term; earliest documented use attributed to Michael McLay) (1994 (coined)) — Bus factor

   The bus factor is the minimum number of team members whose loss would halt a project — a popular way to describe the risk that arises when critical knowledge is concentrated in one person.

6. Non-zero-sum games / game theory

   John von Neumann and Oskar Morgenstern (1944) — Theory of Games and Economic Behavior

   Von Neumann and Morgenstern founded the mathematical theory of games, and in 1950 John Nash extended it with an equilibrium for non-zero-sum games, where parties can win simultaneously.
