Long before the sustainability debate went mainstream, Peter Senge poineered a new way of thinking about organisational sustainability. Remarkably, his theory of SYSTEMS THINKING (first published in 1990) was based on the concept that the world of business and markets are entirely interconnected, similar to the planet’s ecosystems. Therefore, organisations must learn and evolve in order to survive and thrive. This process has been named ‘organisational learning’, where ‘people are continually learning to see the whole together’. Senge has been widely acclaimed and awarded because of his many books and articles on Systems Thinking, Organisational Learning and Sustainability: He was named as one of the top 20 most influential business thinkers by the Wall Street Journal in 2008.
