Dude, Cut Me Some Slack

Since I enjoyed reading Tom DeMarco’s “Slack: Getting Past Burnout, Busywork and the Myth of Total Efficiency” years ago, this diagram in¬† Jamshid Gharajedaghi’s “Systems Thinking: Managing Chaos and Complexity” brought back some fond memories of that book:


The diagram shows the slow, insidious erosion in flexibility that occurs in a complex system when efficiency and optimization initiatives are relentlessly applied to the system by its uninformed stewards. As the “slack” is stretched out of the system due to increasing internal pressure, it: 1) loses its robustness to external stressors, 2) the tension between connected nodes increases, and 3) the inter-node couplings harden. At the system breaking point, one or more of the connections crack open, the nodes fly apart, and the conglomeration ceases to function as a whole – a system. I hate when that happens!

A Danger To Themselves And Others

“Efficient systems are dangerous to themselves and others” – John Gall

A new system is always established with the goal of outright solving, or at least mitigating, a newly perceived problem that can’t be addressed with an existing system. As long as the nature of the problem doesn’t change, continuously optimizing the system for increased efficiency also joyfully increases its effectiveness.

However, the universe being as it is, the nature of the problem is guaranteed to change and there comes a time where the joy starts morphing into sorrow. That’s because the more efficient a system becomes over time, the more rigid its structure and behavior becomes and the less open to change it becomes. And the more resistant to change it becomes, the more ineffective it becomes at achieving its original goal – which may no longer even be the right goal to strive for!

Eff vs Eff

In the manic drive to make a system more efficient (so that more money can be made with less effort), it’s difficult to detect when the inevitable joy-to-sorrow inflection point manifests. Most managers, being cost-reduction obsessed, never see it coming – and never see that it has swooshed by.¬†Instead of changing the structure and/or behavior of the system to fit the new reality, they continue to tweak the original structure and fine tune the existing behaviors of the system’s elements to minimize the delay from input to output. Then they are confounded when (if?) they detect the decreased effectiveness of their actions. D’oh! I hate when that happens.
