In my previous discussion of the ACPO national decision model (May 2014), I promised to return to the methodological question, namely what theories of decision-making would be relevant to NDM and any other decision models. I have just happened upon a doctoral thesis by Maxwell Mclean looking at the decision-making by coroners, which analyses local variation in coronial outcomes at three decision-making stages: whether to report the death, whether to advance to inquest, and the choice of inquest conclusion.
Mclean notes that there is no decision-making model for coroners equivalent to the police national decision model and focussed on standards and consistency of outcome. He finds other examples of decision-making models in nursing (Lewinson and Truglio-Londrigan, 2008; Husted and Husted, 1995; Jasper, Rosser and Mooney, 2013); social work (O’Sullivan, 2011; Taylor, 2010); and probation work (Carter, 1967; Rosecrance, 1985). However, several of these are descriptive models rather than normative models.
Within the professions mentioned by Mclean, I found a lot more work on evidence-based nursing as well as some interesting international discussions on decision-making within offender supervision. Looking further afield, I was interested to find an article about a decision-making model in the US Army, but this turned out to be merely a polemical article by a former Navy Seal advocating the use of Design Thinking.
Rosecrance introduces an interesting concept of the Ball Park, where a professional decision is influenced by the anticipated reaction of a more senior professional. For example, the decisions of a probation officer are not solely designed to achieve the desired outcomes for the client, but also designed to meet the approval of (1)
judges, (2) prosecuting attorneys, and (3) probation supervisors. When a
recommendation seems likely to meet the approval of these three
entities, it is said to be "in the ball park". The "ball park" concept is also used in sales negotiations, and this hints at the idea that the focus here is on "selling" (or at least defending) the decision rather than just making it.
Coming back to the police, this frames the NDM not just as a way of making the best decision but also avoiding censure if anything goes wrong. See my post on the National Decision Model and Lessons Learned (February 2017).
