Textbook Question
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).

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

- 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.arrow_forwardWrite a short note on project implementation on the below topic Identification of possible risks (Classification of risks)arrow_forwardA project scope definition document for a Reusable Water Bottle.

The center needs to remodel one ofthe rooms in time for the start of a new program. Delays in the project mean that the center mustrent other space at a nearby church at additional cost. Time and cost data for your project arecontained in below table. Your interest is in minimizing the cost of the project to the communitycenter.Using the normal times for each activity, what is the earliest date you can complete the project?Suppose the variable overhead costs are $50 per day for your project. Also, suppose that thecenter must pay $40 per day for a temporary room on day 15 or beyond. Find the minimum-costproject schedule using below format.The AON diagram for the community center project is below. Crash 4 times and find total cost.arrow_forwardRefer to the Table 1 and do the following: Calculate the Expected time, mean time. Develop the Network diagram using the expected time and use PERT Analysis to know the mean and Sd of the project. Based on these estimates and the resultant expected project duration of 69 days. The executive committee wants to know what is the probability of completing the project before a scheduled time of 68 days? How do you measure project risk exposure? Explain and propose ways to reduce the project risk exposure.arrow_forward
