It is vital to distinguish “data” from “information” 3

When an engineer must restart a project several times it requires multiple “set ups”. Unsynchronized concurrent tasks One of the most insidious wastes. It seems like the right thing to do but unsynchronized concurrency is often the root cause of a great deal of waste.
