Well I hope that the last seminar for NMOR in SSM modelling crystalised a few more insights into usefulness of the approach. I've found that this weeks modelling provoked some 'critical' questions as to where to set the boundary to the model on 'professional planning of production plans.
You might not be that keen on manufacturing operations (as I once was in a previous role) but if you take your observations about what doubts and questions you were faced with in the modelling ( Here is where your blog comes in…. make use of it!), you can reflect upon these and ask 'why might it be useful to be guided by the modelling to ask that kind of question?' – you will have lots of useful material to be able to evaluate SSM.
