Foundation Sprint Magic Lenses

Day 2 afternoon of a Foundation Sprint. The team evaluates each candidate approach from multiple perspectives, surfaces contradictions, and produces a top bet plus a backup plan. The Decider names both; without an explicit backup, invalidation of the top bet sends the team back to ambiguous debate.

When to Use

• Day 2 afternoon of a Foundation Sprint.
• Approach Options is signed; the team has 3-7 candidate approaches advancing.
• The team has at least 1 team-specific custom lens prepared (per ratified spec decision; classic lenses alone are insufficient).

When NOT to Use

• Approach Options is unresolved or under-numbered (fewer than 3). Force a third option through the approach-options skill first.
• The team has pre-committed to a top bet. Magic Lenses is a sense-making exercise; if the decision is already made, the time is better spent on Founding Hypothesis.
• The team is exhausted and cannot evaluate clearly. Postpone to Day 2 morning of a follow-up sprint rather than rush.
