Project managers must make decisions constantly. If they fail to do so, their projects will likely not progress. If they do make decisions, they must make those that further the vision of their projects. Successful project managers, therefore, are individuals who make the "right" decision at the right place and right time. However, they do not do so in a vacuum . They know that they need input from others, especially from the people who must implement their decisions if they hope to avoid quixotic results. Involvement by others ensures that the people who implement decisions are committed to translate them into meaningful action and take corrective action.
