Past practices for engineering leaders.
Sampler
Three past practices worth starting with.
All practices
Judgment requires tolerating unresolved tension.
— Albert O. Hirschman
Organizations drift toward decisions that minimize conflict, not risk.
— Chris Argyris
Rules are best when they are treated as resources, not commands.
— Karl E. Weick
Organizations often treat symptoms because causes are politically difficult.
— Chris Argyris
The absence of complaints does not imply satisfaction.
— W. Edwards Deming
Every solution creates new problems.
— Daniel L. Katz
Organizations drift when learning is subordinated to performance.
— Chris Argyris
Management is prediction.
— W. Edwards Deming
Organizations drift when learning is decoupled from decision-making.
— Chris Argyris
What you reward is what you get.
— James Q. Wilson
Complex systems fail where learning is suppressed.
— Chris Argyris
An organization cannot outperform the quality of its decisions.
— Peter Drucker
Control increases predictability at the cost of adaptability.
— Chris Argyris
Complex systems amplify small coordination failures.
— Charles Perrow
The price of reliability is the pursuit of flexibility.
— Karl E. Weick
Complexity and tight coupling make failure inevitable.
— Charles Perrow
Systems fail where responsibility is diffused.
— Hyman G. Rickover
The more tightly a system is coupled, the more it resists local fixes.
— Charles Perrow
Most organizations change only after the cost of not changing becomes too high.
— John P. Kotter
Standardization makes things efficient, but it also makes them fragile.
— Charles Perrow
Systems drift because no one owns the accumulated risk.
— Barry Turner
Decisions without feedback are guesses.
— John Boyd
Organizations drift when risk is reframed as acceptable variance.
— Barry Turner
Judgment improves when leaders treat authority as a responsibility, not a right.
— Hyman G. Rickover
Organizations normalize risks that accumulate slowly.
— Barry Turner
Speed and learning are inseparable.
— John Boyd
Complex systems hide their failure modes during normal operation.
— Charles Perrow
Organizations prefer reversible decisions even when irreversible ones are required.
— Barry Turner
What appears to be irrational behavior often makes sense within a local context.
— James G. March
Control mechanisms reduce surprises while increasing fragility.
— Barry Turner
Judgment erodes when rules replace responsibility.
— Hyman G. Rickover
Systems drift when incremental changes escape scrutiny.
— Barry Turner
Nearly all failures in decision making come from making decisions in isolation.
— Irving L. Janis
Complex systems amplify small errors through normal operation.
— Charles Perrow
Organizations drift when small compromises go unexamined.
— Barry Turner
Good decisions leave room for correction.
— Herbert A. Simon
Control mechanisms age faster than the risks they are meant to manage.
— Barry Turner
Reliability is the absence of surprises, not the absence of change.
— Gene Kranz
Most failures are preceded by decisions that felt reasonable at the time.
— Barry Turner
You manage what you pay attention to.
— Herbert A. Simon
Organizations act rationally within irrational systems.
— Charles Perrow
Stability creates the conditions for surprise.
— Barry Turner
All models are wrong, but some are useful.
— George E. P. Box
Most breakdowns are preceded by a long period of unnoticed warning signals.
— Barry Turner
Judgment fails when leaders treat uncertainty as incompetence.
— Frank H. Knight
Every simplification hides a choice about what to ignore.
— Albert O. Hirschman
A good model enables you to be wrong faster.
— George E. P. Box
Without a theory, experience has no meaning.
— W. Edwards Deming
Systems drift when long-term consequences remain abstract.
— Albert O. Hirschman
Organizations adapt faster to pressure than to insight.
— Geoffrey Vickers
Control reduces variance at the expense of adaptability.
— W. Edwards Deming
Every standard carries an implicit theory of failure.
— Erik Hollnagel
Control reduces variation but also reduces information.
— W. Edwards Deming
Judgment improves when leaders decide what must remain uncertain.
— Frank H. Knight
What looks like a violation is often the only way the work gets done.
— Sidney Dekker
A system is never the sum of its parts; it is the product of their interactions.
— Russell L. Ackoff
Expert judgment requires accepting that some uncertainty is irreducible.
— Frank H. Knight
Every increase in efficiency increases vulnerability.
— Dietrich Dörner
Safety is not a component, but an emergent property of the system.
— Nancy Leveson
Every act of measurement disturbs the system being measured.
— Donella H. Meadows
Organizations often learn the wrong lessons from failure.
— Amy C. Edmondson
A complex system that works is invariably found to have evolved from a simple system that worked.
— John Gall
Organizations optimize what can be audited, not what matters.
— Jerry Z. Muller
The greatest source of error is the belief that one is not biased.
— Daniel Kahneman
Failures are rarely caused by isolated errors but by the unexpected interaction of multiple factors.
— James Reason
High reliability is not the absence of errors, but the presence of capabilities that detect and contain them.
— Karl E. Weick
Design is the art of arranging constraints.
— Charles Eames
A decision is a commitment to action under uncertainty.
— Howard Raiffa
The most dangerous failures are those that appear rational at the time.
— Barry Turner
