Decision-Making Models

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 d…

National Decision Model and Lessons Learned

The appointment of Cressida Dick as the first female commissioner of the Metropolitan Police has been criticized in some quarters because of her involvement in the fatal shooting of Jean Charles de Menezes in 2005.

Dick was the “gold commander” who instructed armed officers to “stop” de Menezes. At the time, however, armed officers were following a new set of police guidelines known as Operation Kratos. In the context of these guidelines, Dick’s orders were interpreted as shoot-to-kill. At the Old Bailey in 2007, Dick denied that this had been her intention.

As Mary Dejevsky argues, the de Menezes case provides a lasting reminder of what can go wrong

“whether because the overall atmosphere has not been properly appraised, because the orders given were not precise enough, or simply because insufficient account has been taken of the human factor”.

The National Decision Model, which was introduced a few years after this incident, provides a framework that should (at least in theory) prevent this kind of miscommunication. See my post on the National Decision Model (May 2014). Perhaps this is one of the areas where “lessons have been learned”. Or perhaps not.

Iain Gould is a solicitor. One of his clients was involved in an incident in 2013 that resulted in his being tasered. The Independent Police Complaints Commission (IPCC) attributed this escalation, in part, to a failure to follow the National Decision Model.

“I would question whether PC B gave enough emphasis to the first element of the National Decision Model, which is to communicate. … More effort should have been made, in line with the National Decision Model, to engage Mr S in dialogue.”

The IPCC commissioned a report in 2015, which contains some analysis of the National Decision Model, and some recommendations for its improved use. There are two versions of the report:

    People have a complicated relationship with the concept of cause and effect.

    Situational awareness, according to Wikipedia, is defined as “…the perception of environmental elements and events with respect to time or space, the comprehension of their meaning, and the projection of their status after some variable has changed, such as time, or some other variable, such as a predetermined event”. In other words, it’s having a […]

    In my post “Strategic Tunnel Vision”, I touched on the concept of capability.

I also spoke to how choices about strategic capabilities can trickle down to effect tactical capabilities. What […]
