What term would be used to describe a tool that allows for interaction and input from multiple stakeholders?

The correct term for a tool that facilitates interaction and input from multiple stakeholders is "collaborative games." Collaborative games are interactive methods designed to encourage participation, idea generation, and creative thinking among diverse groups. They allow stakeholders to contribute their perspectives in a structured yet flexible environment, making it easier for everyone to share thoughts, brainstorm solutions, and build consensus.

Using collaborative games enhances engagement and helps uncover insights that might not surface through traditional elicitation techniques. These tools are particularly useful in environments where input from various stakeholders is vital for effective decision-making, as they promote dialogue and collaborative problem-solving.

In contrast, "business requirements" refer to the high-level needs of an organization and do not inherently involve stakeholder interaction. "Closed questions" primarily lead to limited responses, which would not foster the interactive dialogue needed for stakeholder input. A "decision requirements diagram" is a visual representation of decisions and their relationships but does not serve as a tool for active stakeholder engagement in the same way as collaborative games do.
