Which changes would not shift the demand curve for a good or service?

There is just one person in our group, silvia, who seems to have radically different ideas about how to complete our project. she seems to purposely disagree with the majority opinions of the rest of us though yesterday she said something that made a lot of sense to us solve our production problem. i suggested to the entire group today that we hear silvia’s suggestions and asked silvia to share in-depth more of what she said yesterday. i am using which adaptive leader behavior?
