Avoid redundancy, don’t repeat information from views or concepts.

In the tabular version of the solution strategy (shown in tip 4-2 (solution strategy as table) and tip 4-3 (solution in context with quality requirements)) you should document only briefly - and refer (link) to detailed explanations in arc42 sections 5 (building blocks), 6 (runtime view) or 8 (crosscutting concepts).

Links to external documents or references are ok, as long as your stakeholders can easily find and access such refered-documents.
