Two weeks is the worst sprint length

Your understanding of Kaizen is wrong

Most Agilists and Leanists use Kaizen in the context of team improvement. That is, an agile team should continuously improve, and thus excluding the managers/leaders and the rest of the company. This is exactly where the understanding goes wrong.

A Quick Measure of Sortedness

How do you measure the "sortedness" of a list? Here, I propose another measure for sortedness. The procedure is to sum the difference between the position of each element in the sorted list, x, and where it ends up in the unsorted list, f(x). We divide by the square of the length of the list and multiply by two, because this gives us a nice number between 0 and 1. Subtracting from 1 makes it range from 0, for completely unsorted, to 1, for completely sorted.
