Parents often criticize teens' clothes because they represent bad technology. If you want clothes to protect you from the cold, then your daughter's selection of light chiffon and an ultra-mini represents bad technology. But if you want clothes to accentuate your physical features, then the same clothes represent good technology. Good technology minimizes the possibility of unexpected consequences by minimizing the potential for operator error. It is also robust, less prone to breakdowns and malfunctions.
Reliability seems like an obvious point but is frequently overlooked in less critical environments.
Software that crashes instead of running is bad technology, obviously. Telephone systems that connect you to India instead of Indiana are not useful. No technology is perfect. No technology will satisfy all nine rules. But some will satisfy more of these rules than others.
