Solution Strategy
A short summary and explanation of the fundamental decisions and solution strategies, that shape system architecture. It includes
-
technology decisions
-
decisions about the top-level decomposition of the system, e.g. usage of an architectural pattern or design pattern
-
decisions on how to achieve key quality goals
-
relevant organizational decisions, e.g. selecting a development process or delegating certain tasks to third parties.
These decisions form the cornerstones for your architecture. They are the foundation for many other detailed decisions or implementation rules.
Keep the explanations of such key decisions short.
Motivate what was decided and why it was decided that way, based upon problem statement, quality goals and key constraints. Refer to details in the following sections.
See Solution Strategy in the arc42 documentation.
