Assume you are working on a complex project in your organization, and it involves in-house staff, as well as contractors. Some of your team members work in different locations. At first, the team members did not really understand their roles and responsibilities and were not that committed to the project. To avoid cost and schedule overruns, you learned you needed to have a lot of meetings with your team to obtain their buy-in and use more of a command and control leadership approach. Now, however, a year has passed, and the project is on schedule and within budget. There is greater trust among the team members. You have learned since this team is more mature that you—

a. Can use an adaptive project life cycle

b. Should focus on networking and professional development

c. Can use a flexible leadership style

d. Can promote interface relationship management
