Systems Thinking

In essence: Complex systems can't be understood by looking at their parts in isolation—the connections and feedback loops between components often matter more than the components themselves.

Core Ideas

  • Emergence: System behavior emerges from interactions, not individual parts
  • Feedback Loops: Actions create reactions that amplify or dampen the original action
  • Unintended Consequences: Complex systems often respond to interventions in unexpected ways
  • Holistic View: Understanding requires looking at the whole, not just the parts

Common Pitfalls

  • Optimizing parts while harming the whole
  • Ignoring feedback loops
  • Focusing only on immediate effects
  • Assuming linear relationships

Olive Garden pasta water memo

During due diligence, it was discovered that Olive Garden stopped salting their pasta water to extend pot warranties. This perfectly illustrates how optimizing for equipment maintenance (a subsystem) undermined food quality (the system's purpose). It shows how focusing on a subsystem without considering the whole system can lead to perverse outcomes.

A classic example of a feedback loop where attempts to manage a system create more of the problem you're trying to solve.

"If you drop a frog into boiling water he will scramble to get out. If you drop him into room temperature water he will sit still no matter the temperature increases. The frog reacts to sudden changes but not slow gradual changes."

Organizations often fail to notice and respond to gradual changes in their environment, making them vulnerable to systemic threats that build up slowly.

Complex Organizations

"A Detroit auto maker examining a Japanese import found the Japanese car used the same bolt throughout the engine where the American car used 3 different bolts in 3 different components designed by 3 different engineers."

This example shows how system-level thinking (standardization) versus component-level thinking (individual optimization) leads to vastly different outcomes. Systems designed holistically often outperform those designed in isolation.

"A company is like a cthonic beast with many writhing tentacles that is in fact composed of thousands of cats. A black mass of cats, writhing, seeking, crawling toward anything that will increase its share price or get a cat promoted..."

This vivid metaphor captures how large organizations often act as emergent systems, with behaviors arising from thousands of individual actors pursuing their own interests rather than following central direction.

"Most successful corporations are learning organizations. The ability to learn faster than the competition is the only sustainable competitive advantage."

Learning and adaptation are fundamental to system survival and success. Organizations that can't learn and adapt quickly become obsolete.

"Early innovations and movers pave way for learning organizations. The Wright brothers first flight was 1903. First commercial flight was 1935."

System evolution often follows long periods of experimentation before reaching commercial viability. The path from innovation to widespread adoption is itself a complex system.

"Survival learning = doing minimum necessary to service. Generative learning = learning that enhances our capacity to create."

Systems can operate at different levels of learning and adaptation, from basic survival to generative growth.

"FedEx in the late 1990s crunched the numbers on its 30 largest clients—a group that generated about 10% of the shipping firm's total revenues and volume. The company found that certain clients, including some who required lots of residential deliveries, weren't bringing in as much revenue as they had promised when they first negotiated discounted rates with FedEx."

Even seemingly valuable customers can create systemic inefficiencies when analyzed holistically. What looks profitable at the surface level may hide deeper system-wide costs and complexities.
