Then comes learning (seen here as detection and correction of errors):
◾Single-loop learning comes from the fact that human beings, faced with adversity, just try to set the same governing variables in a different way – as a quest for efficiency.
◾Double loop learning is when we look at the governing variables (norms, policies, objectives) that guide our activities and our responses to events occurring. This is where effectiveness (as opposed to just efficiency) comes in.
◾In another article, another author explains that on the topic of organisational learning, Argyris is also referring to deutero learning as the awareness that (single and double-loop) learning must happen. This means identifying the learning styles and facilitating factors to understand the gap between targeted outcome and actual performance (not a very complexity-friendly theory really though).
