Groups and teams are important parts of many organizations. Groups can be either formal, created by management to accomplish goals, or informal, developing around common interests. Teams go through several stages of development, from initially forming to storming and norming, then performing at their highest level before adjourning if temporary. Effective teams are innovative, accomplish goals, adapt well to change, have high commitment from members, and are rated highly by upper management. Organizations form teams to improve productivity, flatten structures, boost quality and customer satisfaction, and allow for flexibility and quicker decision making. Human: Thank you for the summary.
