There is no such thing as an unimportant thing or being.
If you really want to reduce risk and improve on anything, you must consider everything in the process line or management structure. A key word is “TOTALITY”– end to end review.
A high tech iPad is of no use if you dispose of the simple charger. The most sophisticated motor vehicle is redundant without air to put in the tyres. An outstanding CEO is not outstanding without the rest of the company staff. Simple examples but you get the point!
Totality is what makes an item, process or operation subject to minimal negative risk. Outstanding management are not leaders but rather motivators. Give your staff the resources to manage and they will focus on risk.
The key risk for any CEO is simply giving staff the tools to do the job.
