Go for excellence not perfection

Excellence says 'good'. It's the act and output of excelling with good qualities in high degree. Yet some parts may not be excellent and these we hope will be the parts that don't really matter or those that can be improved over time.

My mother, Shirley, put a little sign in our family home years ago that read: ‘I may not be perfect, but parts of me are excellent.’ This is what it's about! Parts of our project, task or activity could well be admirable, impressive, grand and outstanding. And other parts...may be less than that.

Industries that have established 'Centres for Excellence' - in my local region - include Science, Child and family health, Disability, Railways, Youth mental health, and Automotive.

These sectors know that everything isn't perfect but parts of them are excellent; the parts that matter.

They want to improve and get better with both the parts that are already excellent and the parts that need to be a bit more excellent!  

Let me know what you think. Could you go for something like ‘iterative improvement’ or ‘progressive excellence’, rather than trying to make things perfect?
