MDPE.21:2.4 - Develop several architecture candidates
Do not let the first plausible intervention define the architecture. Develop materially different candidates. For example:
| Candidate emphasis | Change considered | What it may reveal |
|---|---|---|
| Capability-first | Change drills, embodied correction, listening practice, rehearsal, or ensemble training. | Whether performers can enact the distinction in representative Work. |
| Recognition-first | Change examples, comparison tasks, partner cues, judging or curation, and how learner, partner, listener, judge, or curator observations are used in later teaching or selection. | Whether a relied-on Agent can discriminate the distinction and use that observation in the next Work. |
| Transmission-first | Change teaching, joint practice, notation, demonstrations, recordings, or reconstruction tasks. | Whether another Agent can reproduce and adapt the practice rather than copy one artifact. |
| Circulation-and-memory-first | Change event recurrence, repertoire, archives, publishing form, access, or retrieval. | Whether later Work can recover the practice under changed people, places, or media. |
| Medium-first | Change instrument, software, camera arrangement, platform, venue, or production System. | Whether the support System enables the intended Work instead of selecting another result. |
| Coupled minimal change | Change two or more tightly linked relations whose separate repair would fail. | Whether the joint change resolves a conflict that neither local repair can resolve alone. |
These are candidate emphases, not prescribed kinds. A useful candidate states the Systems and Methods it changes, the Agents whose Work or capability is involved, the direct signal, contact, access, teaching-use, observation-use, selection, or other relations changed, the authority and consent needed, the expected effect, and the earliest observation that could defeat it.
