NOTE: The Modelling
Discipline is special. It could be called a Meta-Discipline. It is special
because it is never done on its own, It’s only every used by the other
Here we see the five main sub-disciplines of Modelling:
Determine the Question
Here we identify a question that needs to be answered. There is
no reason to model anything unless it will be used to answer a question. Either
the question cannot currently be answered or the quality and confidence in an
existing answer is too low to be useful.
Determine Required Data
Having understood what the question is, here we identify what
information will be required in order to answer it.
Populate the Model
Here we find the information identified and populate the model
with it. This should be thought of as effectively a data migration exercise -
as illustrated by the sub process shown.
Integrate the Data
Here we ensure that information that has been loaded into the
model is sustainable and will be maintained.
For each source of the information loaded, there are two
alternatives (which were identified in the Analysis Phase of the Populate the Model sub process).
The source is removed - The people and/or processes and/or
technology using the original source will stop using it and will use the
information in the model in the future.
The source is preserved - The necessary Methods, Artefacts,
Cultural and Environmental things are put in place to enable the synchronisation
and management of the data going forward with the people using it.
Answer the question
Having populated the model, it is now possible to use the model
in concert with the tools and analyses provided by the modelling tool to answer
