we wouldn't drink from a milk carton without checking for the expiration date first. So why don't we act the same way at work?
Why not give every policy, every vendor, every machine...every employee... an expiration date. On that date, we need an overwhelming reason to keep he/she/it or out it goes.
Today, of course, the opposite is true. Inertia is in charge, and as a result, we get stuck, we don't evolve.
Fast feedback loops, quick generations--that's what the fashion world is about and that's how we evolve quicker.
