Slove the quation: Tony and his team identified some risks during the first month of the Recreation and Wellness Intranet Project. However, all they did was document the risks in a list. They never ranked the risks or developed any response strategies. Because the project has had several problems, such as key team members leaving the company, users being uncooperative, and team members not providing good status information. Tony has decided to be more proactive in managing risks. He also wants to address positive risks as well as negative risks. The quation is ; Develop a response strategy for one of the negative risks and one of the positive risks. Enter the information in the risk register.

Project Scope Management Khan, (2006) (see below) states that, "Managing the scope of a project is the most important function of a project manager ... Effective scope management of a project also ensures the success of key completion areas, including time, cost, and quality. Project scope management can be further subdivided into its components which include: project initiation, scope planning, scope definition, scope verification, and scope change control." Based on your Integrated Project: Select two of the subdivisions above and discuss the primary issues that could arise from the process. Your response should begin with a definition of the selected subdivision before detailing the selected process
