My first impression of the process at the Board was that the judgmental team made its forecast without a model and the model team made its forecast without judgment, leaving the blending of model and judgment to be worked out in the process of discussion and iteration as the judgmental group looks at the model output and the model group joins the discussion of the forecast.
The process is, I have come to appreciate, more complicated and subtle than this caricature. For example, when there have been important shocks (e.g., unexpected rise in oil prices or an increase in the minimum wage), model simulations of the effect of the shocks will provide a point of departure for the initial judgmental forecast.
