9. Architecture Decisions

[TBD]

Tips for completing this section

Contents

Important, expensive, large scale or risky architecture decisions including rationals. With "decisions" we mean selecting one alternative based on given criteria.

Please use your judgement to decide whether an architectural decision should be documented here in this central section or whether you better document it locally (e.g. within the white box template of one building block).

Avoid redundancy. Refer to section 4, where you already captured the most important decisions of your architecture.

Motivation

Stakeholders of your system should be able to comprehend and retrace your decisions.

Form

Various options:

  • ADR ((Architecture Decision Record)) for every important decision
  • List or table, ordered by importance and consequences or:
  • more detailed in form of separate sections per decision

Further Information

See Architecture Decisions in the arc42 documentation. There you will find links and examples about ADR.
