Consensus: General agreement, unanimity, judgment arrived at by most of those concerned; group solidarity in sentiment and belief. From Latin consentire, cōnsēnsus agreement, from cōnsentiō meaning literally feel together.

For Americans, businesses, and therefore the teams within them, are not democracies. American team leads do not feel obligated to reach consensus within their leadership group in order to set strategy or to make a decision. Both sides of the relationship – leaders and led – are in agreement that the lead is paid to set strategy, make decisions, not to be a moderator.

Team members, as specialist in their areas, want and expect to be listened to. They want their input to have impact on the decision to be made, the strategy to be set. But they will and can not insist, without possibly damaging their working relationship with the team lead.

Decisive: having the power or quality of deciding; resolute, determined; unmistakable, unquestionable. Synonyms: firm, intent, purposeful, resolved, set, single-minded, do-or-die, hell-bent.
