This course has major project assignments due in Week 3 and Week 5. It will take more than a week’s effort to adequately complete them. Plan time to start the research and work on those assignments earlier than the week in which they are due.
Recently, you have been assigned the task of assembling a multicultural, team in your organization. The purpose of the team is to design and implement a leadership development and succession process for the organization.
Based on research using the course text and other scholarly materials:
Analyze the stages of group development the teams should expect to experience. At each stage, make recommendations that will help move the team into the next stage.
Multicultural project teams often face problems with communication, expectations, and values. How do you think some of these challenges can be overcome?
Explain some of the group decision-making challenges the team may experience and recommend ways to overcome them.
Discuss at least three recommendations to help make these teams effective.
Submit your paper in a 4 to 5 page Microsoft Word document, using APA style.
Support your responses with examples and research.Week 3 Quiz
