Is This a Dialogue Or a Discussion?

Teresa Torres argues that teams struggle when they mix up the phases of idea work: generating options and choosing among them need different rhythms and different conversational modes. Drawing on Tim Brown's divergent-convergent model and Peter Senge's distinction between dialogue and discussion, she shows how to match each phase to the right kind of conversation. She also stresses that the process spirals toward a solution rather than running in circles, and that managing transitions between phases matters as much as facilitating each one. The practical value is in giving product teams clear signals about where they are and how to talk during each stage.

01Key takeaways

• Recognize whether your team is in a divergent or convergent phase, and say so explicitly.
• Use dialogue to build on ideas during idea generation rather than critiquing them early.
• Switch to discussion when it is time to evaluate options and choose a direction.
• Give people time to reflect and sleep on ideas before moving to evaluation.
• When returning to brainstorming, explain what changed, such as a wrong assumption or a roadblock.
• Think of dialogue as inquiry and discussion as advocacy to guide each phase.

The Divergent-Convergent Rhythm

Tim Brown's model alternates between generating new options and eliminating them, with each iteration narrowing toward a solution. Torres notes that teams often get stuck in one phase, and that the process feels circular but actually spirals.

Communicating Where the Team Is

Leaders should explicitly signal whether the group is generating ideas or evaluating them. Clear guideposts make it easier for the team to shift phases together.

Managing the Transitions

Moving between phases needs deliberate care, such as checking whether anyone has more ideas before evaluating, or explaining why a path is no longer feasible before returning to brainstorming. Giving people time to reflect helps.

Dialogue for Divergent Thinking

Following Senge, dialogue is an open, listening-centered exploration where participants surface and test assumptions. The aim is to understand many perspectives, not to pick one, and to build on ideas instead of critiquing them.

Discussion for Convergent Thinking

Discussion is a debate-style exchange where views are defended and weighed to reach a decision. It suits the moment when ideas must be evaluated and a path chosen.

03From the post

“Have you ever been in a brainstorming meeting where the group gets stuck on one idea? They just want to run with it at the exclusion of all else. If your goal is to generate a lot of ideas, this can be pretty frustrating. But what about the opposite? You'”
