What do you mean by 'Confidence Vote' in Scrum? Why is it important?

After the risk analysis, the Confidence Vote is conducted at the Program Increment Planning session. It is when all members of the team meet together and raise their voices and vote with their fingers on their confidence level in the completion of the PI Targets. Only when all of the features and user stories have been appropriately estimated and prioritized can the confidence vote be used. All of the work that is being done must be transparent to all parties involved, with all dependencies and hazards clearly defined.

With a vote of confidence, you can create an environment where individuals feel free to share and express their opinions. It boosts team members' morale since they should feel that their opinions are respected.
