You can look at a domain or an issue from many perspectives.
Each perspective will have slightly different models, frameworks, and other representations to understand the domain or issue.
The perspectives are judged by their usefulness.
As there are many different reasons for understanding domains or issues, there are many different uses for the information.
If the use is to design a new solution, the perspective is different than if the use is to make a strategic decision.
Determine the use to determine the usefulness of different perspectives and then pick the perspective that best suits the use.
