On an agile project the team agreed that decisions would be made by vote and that a 90% agreement threshold will carry a decision. At the first technical design meeting the team makes a decision the project lead strongly disagrees with. How should the project lead proceed?

The correct answer is to note the reasons for the disagreement and let the team proceed. In agile, self-organizing teams are empowered to make decisions. The team established a clear decision-making rule (90% agreement), and that rule was followed. While the project lead may disagree, overriding a team decision made by an agreed-upon process undermines team autonomy and agile principles. Documenting the disagreement is good practice for lessons learned or future reference. Refusing to allow work to proceed or trying to persuade a team member to change their vote are autocratic actions that contradict agile values of self-organization and respect. Involving the project champion for intervention is an escalation that bypasses the team's established process and should be reserved for more significant, unresolvable conflicts, not a disagreement where the team followed its own rules.
