A man walking is never in balance, but always correcting for imbalance.
From Leverage Points
Missing feedback is one of the most common causes of system malfunction.
From How to Use Conscious Purpose Without Wrecking Everything
Ignoring feedback merely means that the system will eventually experience a massive unpleasant surprise rather than a small unpleasant surprise.
The amount of feedback that is built into living organisms differs by many orders of magnitude from the amount that we build into manmade systems.
Flexibility means the willingness to act in response to the feedback message by actually changing how the system works.
From The Principles of Product Development Flow
The speed of feedback is at least two orders of magnitude more important to product developers than manufacturers...
The human effect of fast feedback loops are regenerative. Fast feedback gives people a sense of control; they use it, see results, and this further reinforces their sense of control.
Fast local feedback loops prevent the accumulation of variance.
From Quality Software Management. Vol 1. Systems Thinking
The feedback model says you can't successfully control anything for very long without information.
From Quality Software Management. Vol 2. First-Order Measurement
Software development is not primarily a manufacturing operation for we (ideally) never develop the same software twice. This uniqueness of product means that Deming's "statistical signal" - though necessary - is not sufficient for feedback control, because there often isn't enough repetition - enough stability - to generate meaningful statistics.
From Quality Software Management. Vol 3. Congruent Action
Information about past behaviour, delivered in the present, which may or may not influence future behaviour.
From Quality Software Management. Vol 4. Anticipating Change
In a feedback control system it's only our perception that determines which is controller and which is controllee.
From What Did You Say?
In other words, it's not so much the feedback that counts, but the struggle to get it - not the feedback, but the feeding-back.
We structure our world so we will not receive feedback that threatens our view.
We don't even wait to ignore feedback, but actively take steps to prevent such feedback from ever happening in the first place.
Don't concentrate on giving feedback; concentrate on being congruent - responding to the other person, to yourself, and to the here-and-now situation...
From Management 3.0
Feedback is only feedback when there is a purpose behind it.
From Talent is Overrated
Practicing without feedback is like bowling through a curtain that hangs down to knee level. You can work on technique all you like, but if you can't see the effects, two things will happen: You won't get any better, and you'll stop caring.
Feedback? At most companies this is a travesty, consisting of an annual performance review dreaded by the person delivering it and the one receiving it. Even if it's well done, it cannot be effective. Telling someone what he did well or poorly on a task he completed eleven months ago is just not helpful.
From Agile Development in the Large
Quick feedback should be the first thing you introduce.
From The Dance of Life
All societies depend for the stability on feedback from the people. Depersonalization reduces feedback to a minimum, contributing to instability and lowering the overall level of congruence in the society.
From Understanding the Professional Programmer
Many programmers… work in environments in which they receive essentially no real feedback embodying the consequences of what they do. Lacking no real feedback, they lack the motivation to attempt changes, and they also lack the information needed to make the correct changes.
From The Systems Bible
Just calling it "feedback" doesn't mean that it has actually fed back. To speak precisely: It hasn't fed back until the system changes course. Up until that point it's merely sensory input.
From The Aesthetics of Change
All simple and complex regulation as well as learning involve feedback. Contexts of learning and change are therefore principally concerned with altering or establishing feedback.
From Surfing the Edge of Chaos
Feedback is the means by which a system talks to itself.
From The Fifth Discipline
Virtually all feedback processes have some form of delay.
