Shmi comments on The Centre for Applied Rationality: a year later from a (somewhat) outside perspective

I wonder if a Kumon-style approach, with lots and lots of small steps and exercises done at one’s own pace would be resistant to redesign.

If so, that would be evidence that it is not the best way to implement. The ability to improve a class by redesigning it is a feature of the organization.
