The Loop You Can’t Get Out Of

A few words from the father of system dynamics on organizational decision making, human frailty and the reasons that managers trying to solve problems so often just make them worse.

You’ve already looked at the photograph here, so you already know that Jay Forrester must have seen some things. But the legions who’ve built on Forrester’s work would be quick to tell you that it’s not how many things Forrester has seen, but how he’s seen them, that counts. He’s seen them as the most intricate and interactive of puzzles.

The leading question

How does a renowned “systems” thinker look at the challenges of sustainability?

Findings
  • The biggest challenge facing leaders: how to manage a successful nongrowing company.
  • The biggest problem with how sustainability is being addressed is that we’re treating symptoms, not causes — the same as in most attempts by managers to solve problems.
  • The downturn will likely push real sustainability issues to the rear.

Forrester is famously the originator of the field of system dynamics. It’s helpful (not entirely accurate, but helpful) to think of the approach as an extremely grown-up version of the popular computer game SimCity. Here’s Forrester’s description: “System dynamics deals with how the structure of a system and its information flows determine behavior — the control of growth, stability, decay, success and failure. The field focuses on the way internal feedback-loop relationships cause a system to change through time. Understanding why a system behaves as it does permits redesign of structure and policies to improve behavior. … The field combines theory and computer simulation with a very practical application to real-world problems.” Forrester, now 90 and an MIT Sloan School of Management professor emeritus, joined the Sloan School when it formed in 1956. He was fresh from inventing what we now call RAM (random-access magnetic core memory), and undertook to discover what computers could help us understand about organizations. By the late 1960s he had expanded system dynamics modeling to address the problems of cities (eventually publishing Urban Dynamics) and, after that, world civilization (World Dynamics). It is impossible today not to see these as books about sustainability — maybe among the first great books anywhere about sustainability — even if Forrester wouldn’t call them that.

    I share the same thoughts as Forrester. The two greatest threats to our sustainability are ever increasing population in certain parts of the world and at the same time ever increasing use of technology to make everything more efficiently leading to elimination of work for more through automation. The net effect of these two opposing phenomena will be more people on the earth but less and less of those working and living meaningfully.

    System Dynamics remains a terribly underutilized tool for understanding messy social problems and looking at potential policy solutions. If we are to survive and thrive in the twenty first century, Jay Forrester’s ideas must be embraced and built-upon — not only by tomorrow’s managers, but by tomorrow’s activists, policymakers, citizens, teenagers, program coordinators, philanthropic foundations, etc.

    Very profound and analytical thinking here. Sometimes business owners have to think outside the box, take a step outside there daily objectives and operate from that level. This kind of reminds me a quote that went something like “Dont’ work in your business, work on your business”.
