Deming Cycle is a Spiral

I like to conceptulaize the Deming cycle as a spiral, moving outward with each full turn, rather than a circle coming back to the same point. The idea is that improvement opens new space and leads to further improvement. The idea of a wheel rolling uphill with a backstop does not do it for me.

Deming Wheel as a Spiral

I completely agree with the spiral model of Deming cycle. This way better shows the idea of continuous improvement than the simple wheel.

The Backstop of the Deming Cycle

Tee, regarding your comment on your (natural) uncomfortableness with "the idea of of a wheel rolling uphill with a backstop," I think Deming is making an intentional, important point. When introducing improvements, human nature is such that old practices and habits will quickly resume if you take your eye off the gains. Part of "securing improvement" is to stay with the gains until wholesale new habits have replaced old habits.
There is also an element of wisdom to keeping guard against "Murphy's law".
