Describe a scenario where you would choose a workshop over one-to-one interviews, and one where you would do the reverse.

1. I choose a workshop when the process crosses several teams and the handoffs are contested. Getting sales, service, and finance in one room with a swimlane on the wall resolves ownership questions in an hour that email would take a month to settle.
2. Workshops are also better when I need shared buy-in to a change, because people commit more readily to a design they watched being built.
3. I choose interviews when the topic is politically sensitive, when there is a strong power imbalance in the group, or when I need deep detail from one specialist whose work nobody else understands.
4. Interviews also work better for early exploration, when I do not yet know enough to run a productive group session.
5. In practice I usually sequence them: interviews first to build a hypothesis and surface the disagreements, then a workshop to resolve those disagreements with everyone present.
