A team member missed a project meeting without approval and was penalized per the ground rules. The team claims they had never seen this rule and dispute the penalty. What should the project manager have done to prevent this?

The correct answer is to ensure the team charter was developed by the team members. When team members collaboratively create the team charter, they are more likely to understand, accept, and adhere to the established ground rules, including consequences for non-compliance. This fosters a sense of ownership and commitment. "Ensure team members fully support all decisions" is incorrect because while support is ideal, it's not always achievable for every decision, and the focus here is on understanding and adherence to established rules. "Distribute the project charter to all team members" is incorrect because the project charter defines the project, not the team's operating procedures or ground rules. "Use a charismatic leadership style" is incorrect because while charisma can be beneficial, it doesn't guarantee understanding or adherence to ground rules; a structured, collaborative approach to rule-setting is more effective.
