How do we stop organisations doing stupid things?

Why do organisations do stupid things? I asked myself this question in December when I read that NatWest Bank had been fined £265m for failing to prevent the laundering of nearly £400m.  Over five years a company with an annual turnover of £15m had deposited £365m in bank notes. The cash had been delivered in black bin bags across 50 NatWest branches, including £700,000 at one branch. Some employees at the bank reported their suspicions to those in charge of investigating money laundering but no appropriate action was taken. Read the rest here.
