To think is to make decisions: which facts to pay attention to, how to weight and combine them, what experience and knowledge applies to them, how to mix together the facts and legal knowledge, what to respond – all are decisions.
Everything that happens in a law department results from someone’s decision (or someone’s not making a decision). For example, delegation can be defined as assignment of decision making to someone else. Not evaluating law firms is a negative decision, but with quite profound consequences nevertheless. Creativity, to pick one other relationship, depends on decisions made.
Other characteristics of decisions come to mind. All decisions have probabilities as to whether they are fit for purpose, i.e., was it a good decision, which depends in part on the time period for the assessment. Two months later the evaluation may fall one way, will a year later the evaluation may even reverse. You also need to separate the decision from the process employed to reach it.
