grill-for-unknowns

To identify hidden risks and architectural gaps, you can adversarially stress-test project plans by classifying assumptions into a four-quadrant matrix and evaluating them against seven predefined blindspot lenses to surface unknown unknowns.

The four-quadrant classification method categorizes project gaps into known-knowns, known-unknowns, unknown-knowns, and unknown-unknowns, allowing teams to systematically prioritize focus on material decisions and hidden assumptions during design review.

To review a technical design, apply seven specific analytical blindspot lenses—covering scale, security, failure modes, and rollback—to rigorously evaluate the architecture and identify structural weaknesses before implementation begins.

You need adversarial risk assessment during software engineering and product planning phases when you have a draft architecture and must ensure the team has not missed critical edge cases or irreversible trade-offs before committing to implementation.

The limitation of this adversarial approach is that it requires a draft architecture or project plan to already exist, and it focuses strictly on surfacing structural weaknesses rather than generating new design solutions or writing implementation code.
