One opportunity can map to mutually exclusive directions; do not narrow early

What it is

An unmet outcome can often be filled by several paths that cannot all be taken: mutually exclusive solution directions. Autocomplete versus keeping human review, local cache versus live fetch, explaining to the user versus deciding for them—choosing one often means you cannot pretend to “do a bit of both.” Collapsing to a single direction during identification finishes the selection before any comparison.

Why it happens

Exclusion comes from constraints, not from a shortage of ideas. Attention at one moment, ownership of the same data, a role inside a trust relation, cannot be shared by two opposite strategies. Early narrowing usually has a social cause: someone in the room already has a visual, one direction sounds like this team’s skill. Once a direction is written into the opportunity’s name, later work treats it as decided, and opponents can only attack the whole opportunity rather than that one path. Keeping directions under the opportunity, marked as excluding each other, puts the comparison where it belongs.

Studying it

List at least two workable directions under each opportunity, and write why they cannot coexist: resource, causality, role, or compliance. Use sketches or contrast prototypes to test whether the directions are truly exclusive or only written that way. Record when narrowing happened—identification meeting, first design review, or the afternoon a visual was dropped—and what evidence was in the room. The operational definition of premature narrowing is: a direction was deleted without comparative data on that outcome.

Where it stops holding

Some constraints are already hard at identification (the law forbids auto-approval). Write that as a constraint, not as a choice that emerged from exploration. Fake exclusives (the work could be staged) waste comparison. Narrowing itself is not the error; the error is deleting other directions from the file before comparison.

Applying it

• Hang a “directions” zone under each opportunity card, at least two, with one sentence on why they exclude each other.
• Run ideation per direction; do not draw mutually exclusive strategies as one feature on the same board.
• When a direction is deleted, leave a comparison record: what was compared, what was not, who decided.
• If a visual appears before directions are compared, label it as an instance of one direction, not as the opportunity’s only definition.
