After 2 hours and 14 minutes of discussion, including 3 coffee breaks and 1 heated argument about the meaning of "synergy", the team finally reached a conclusion.
Decision: We will include the "optional" feature in the new software release.
Reason: Because someone in marketing said it would be a "game-changer".
Outcome: Estimated 4 hours of extra development time, 3 bugs introduced, and 1 unnecessary feature.
