Hi Bill

Thank you for your reply.

I think that I did not formulate well enough my question.

The question was not if it is necessary to progress step by step,
which is often preferable (not always) and is largely dependant on the circumstances,
but the influence of the difficulty of the question that the model is supposed to solve, and the
ability of the modeller to ask simple questions but still useful that may generate a much more simple model to build.

The subjective side represents the variable part of the model,
the purposes, constraints, resources allocated
that are chosen by the client, the objective part being the reality.

To summarize the question is: how to choose adequate (preferably simple) purposes and 
constraints to allow for a more simple and manageable model?

Regards.
