Field Notes
As you learn patterns, it is useful to look for the following forces and concepts:
What implementations does this pattern hide? Thereby allowing me to change them.
What commonalities are present in this pattern? This helps me identify them.
What are the responsibilities of the objects in this pattern? As it may be easier to do my decomposition by responsibility.
What are the relationships between these objects? This will give me information about the forces present with these objects.
How may the pattern itself be a microcosmic example of designing by context? This affords me a better understanding of why the pattern is good design.
