|---|---|---|---|---|
Purposedifferent | The TOWS Matrix connects internal strengths and weaknesses with external opportunities and threats into action-oriented strategies. It goes a step further than a pure stocktaking. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. | In early decisions, alternatives are often still vague, incomplete, or blended together. Option Framing brings every possibility into a comparable form and makes visible which variant actually fits the question. |
Complexitydifferent | Medium | Low | High | Medium |
Timedifferent | 1-2 h | 1-2 Tage | Preparation, scenario analysis, and findings review; effort depends on scope | 45-120 min |
Participantsdifferent | 3-10 | 1-4 | Architecture experts and stakeholders for scenarios and weighting | 3-8 |
Formatdifferent | Workshop | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | TOWS Matrix, Strategic Options, Priority Actions | Architecture Document, Context View, Runtime View, Deployment View | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives | Option Frames, Assumption Notes, Comparable Shortlist, Decision Inputs |
