Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++'

Fowler's approach to UML aims to come up with a good design with minimal diagramming. This means that he wants to streamline the design process by only using diagrams that are essential for understanding and communicating the design, rather than documenting every small detail. Therefore, the other options, to document every part of the process and maintain a complicated design, are incorrect because they go against the goal of simplifying and streamlining the design process. Additionally, promoting Extreme Programming, while it may be a part of Fowler's approach, is not the main goal and therefore is not the correct answer.
