What mistake did Gavin make during the brainstorming session when he dismissed Amy's idea for being too expensive?

In a brainstorming session, the goal is to encourage a free flow of ideas where participants feel comfortable sharing their thoughts without the fear of immediate criticism. By dismissing Amy's idea solely on the grounds of it being too expensive, Gavin failed to evaluate the idea in a constructive manner. Instead of considering its potential value or how it might be adjusted to align with budget constraints, he halted the discussion and overlooked the merit it could have brought to the overall project.

Evaluating an idea effectively means assessing it in the context of its feasibility, creativity, and potential impact, among other factors. Gavin's premature dismissal reflects a common pitfall in brainstorming where ideas aren't fully explored, which can stifle innovation and reduce the chances of uncovering a viable solution. In a productive brainstorming environment, even expensive ideas can lead to new insights or inspire adaptations that might reduce costs or enhance value.
