Decision making is a process that lasts a certain amount of time within which a choice is made between two or more options and ends with a decision being made. A team is a disciplined group of people who possess various talents, skills and abilities and use them to achieve a set goal within the company. It turns out that team decision-making is the team’s need for it to fulfill its mission. The most characteristic types within organizations are problem teams, self-managed work teams, interfunction teams, and virtual teams. In order for teams to make the best possible decisions, they must be efficient, that is, "do the right things." Effective teams have clearly defined necessary knowledge of team members, number of team members, team roles or personalities of individual team members and ways of decision-making within teams. Teams use different decision-making techniques, and the most common are: Delphi technique, nominal group technique and brainstorming technique.
