- Data Modelling
- Business Rules Management
- Business Process Modelling, and
- Interaction Modelling (i.e. Use Cases)
We as a community of analysts tend to get early exposure to one and then work to master it. And that works to a point because some disciplined analytical thinking goes a long way no matter how it is applied.
We then augment these basics with more advanced skills and techniques and complement them with social and interpersonal skills and gradually become highly competent analyst/consultants (and sometimes even an Analyst-Therapist.)
Imagine if instead of investing all that energy into mastery of one modelling school we were to instead become generally competent at two, three or even all four? By applying multiple thinking models to the problem at hand we will get a better and more broad understanding that we will from improving our artistry in techniques such as BPMN or Use Case Narratives.
