Decision analysis? – where are the details?

DSC00285edp

In the Milan conference (1st EFLM Strategic Conference Defining analytical performance goals) one of the papers (1) suggests that analytical performance specifications should be prepared from indirect outcome studies using decision analysis. The only example presented is a simulation, which is not decision analysis. Decision analysis is also discussed in this section but on an abstract level.

I have performed decision analysis and discuss it in my book (2). Decision analysis requires a quantitative variable that is either maximized or minimized. In my case, we performed financial decision analysis and the parameter to be maximized was net present value (NPV) of future cash flows. The Milan paper never identifies a quantitative parameter to be optimized.

I don’t understand how decision analysis can be recommended without any known examples or details about how one would go about it.
