One Issue makes life simpler
Keep it Simple, Stupid – or the ‘KISS’ principle – has been recognised since the 1960’s (originally by the US Navy) as a very effective way of making systems work better – particularly when humans are involved. Keeping each step as simple as possible can allow a process to be faster, more repeatable and accurate by inducing less human error and avoiding complexity which can create confusion and doubt – both to be avoiding when the operator is under stress.
