| Criterion |  Systems Thinking Stock and Flow Diagram |  Architecture ARID (Active Reviews for Intermediate Designs) |
|---|---|---|
Purposedifferent | A Stock and Flow Diagram shows how stocks, inflows, and outflows shape a system over time. It is especially suited when growth, delays, or capacity limits determine the dynamics. | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. |
Complexitydifferent | High | Medium |
Timedifferent | 2-6 h | 2–4 h review as a planning range; preparation and evaluation additional |
Participantsdifferent | 1-6 | Designers, developers as users, and facilitation |
Formatsame | Workshop + async | Workshop + async |
Outputdifferent | Stock and Flow Model, Dynamics Notes, Simulation Hypotheses | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions |
