I have just come across this document called "Engineering better care a systems approach to health and care design and continuous improvement at
raeng.org.uk/publications/r...
It is produced by the Royal Academy of Engineering.
There are some nice approaches in it that may be applicable to people who are trying to get a better service from the NHS.
I like the quote on page 24 figure 2: "Figure 2: A system of systems — different perspectives on the human body The human body is a system of systems, comprising amongst others the circulatory, digestive, nervous, integumentary, muscular, skeletal and respiratory systems. Each has its own purpose and function and yet when combined, they produce for the body qualities not present in any of the individual elements."
It is better than any document that I have seen produced by the NHS marketing people to try and imply they are doing a wonderful job.
I hope some people will find it useful.
