domains offer a "sense of place" from which to analyse behaviour and make decisions. The domains on the right, clear and complicated, are "ordered": cause and effect are known or can be discovered. The domains on the left, complex and chaotic, are "unordered": cause and effect can be deduced only with hindsight or not at all. Clear The clear domain represents the "known knowns". This means that there are rules in place (or best practice), the situation is stable, and the relationship between cause and effect is clear: if you do X, expect Y. The advice in such a situation is to "sense–categorize–respond": establish the facts ("sense"), categorize, then respond by following the rule or applying best practice. Snowden and Boone (2007) offer the example of loan-payment processing. An employee identifies the problem (for example, a borrower has paid less than required), categorizes it (reviews the loan documents), and responds (follows the terms of the loan). According to Thomas A. Stewart, This is the domain of legal structures, standard operating procedures, practices that are proven to work. Never draw to an inside straight. Never lend to a client whose monthly payments exceed 35 percent of gross income. Never end the meeting without asking for the sale. Here, decision-making lies squarely in the realm of reason: Find the proper rule and apply it. Snowden and Boone write that managers should beware of forcing situations into this domain by oversimplifying, by "entrained thinking" (being blind to new ways of thinking), or by becoming complacent. When success breeds complacency ("best practice is, by definition, past practice"), there can be a catastrophic clockwise shift into the chaotic domain. They recommend that leaders provide a communication channel, if necessary an anonymous one, so that dissenters (for example, within a workforce) can warn about complacency. Complicated The complicated domain consists of the "known unknowns". The relationship between cause and effect requires analysis or expertise; there are a range of right answers. The framework recommends "sense–analyze–respond": assess the facts, analyze, and apply the appropriate good operating practice. According to Stewart: "Here it is possible to work rationally toward a decision, but doing so requires refined judgment and expertise. ... This is the province of engineers, surgeons, intelligence analysts, lawyers, and other experts. Artificial intelligence copes well here: Deep Blue plays chess as if it were a complicated problem, looking at every possible sequence of moves." Complex The
