Good architects are rare and busy people. There is a great shortage of good architects. Compare them to mid fielders in football or soccer, they will go the extra miles. They are fire fighters, especially where it concerns supporting fellow architects and responding to email. They have good nerves and can stand stress. And even with a busy schedule they will find the time to assist other, more junior architects. They fly from place to place to sort things out, bringing order to chaos.
Simple systems do not need architects.The following books may make sense in this respect :
Chaos and Complexity.
Good architecs have good nerves - they have composure to champion new ideas. They are like grand masters of chess, with the able capacity to manage all 64 squares of the board. Many of them have a background in mathematics. They are both learning and teaching, both student and master of the trade, artists, really.
They are the spider in the web, the center, between business development, delivery and operations.
