Chapter 17, Problem 13P
Here is a list of activity times for a project as well as crashing costs for its activities. Determine which activities should be crashed and the total cost of crashing if the goal is to shorten the project by three weeks as cheaply as possible. First construct a network diagram. You can use either an AOA or an AON (see Solved Problem 5).

For this assignment, you will design a risk management plan for a project titled “prolonged waiting times for patients in a large outpatient hospital” that will include the following elements:
Risk Register/Matrix (list of at least 5 (five) risks along with the associated impact and probability scores along with risk score)
Contingency plan (list of any risks you will plan for in advance along with what triggers the contingency).
Be sure to include any information useful to stakeholders on the rationale for the creation of these elements as well as any outside references supporting the risk management plan.
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
