About a decade ago, when I served on a local ASTD chapters board, I began to ponder the stalemate that can occur when trying to reach a decision through consensus. During one particularly drawn-out meeting, I found myself listening to human resource colleagues circling in conversation without deciding anything. Sitting there, I reflected on the fact that individuals within a group can hold different mindsets about the decision at hand. During that meeting, I created what I call ChoiceMarks for the best-possible decision makingmindsets for thinking about decisions.
