Consider a project with seven tasks. Three tasks – tasks 3, 4, and 5 – require a specific resource for completion; all needed resources must be available at the site before a task can be started. Task Duration Predecessor (s) Units of Value of Resource Completed Task Needed 3 3 10 $4000 3 1 10 S3000 3 12 $5000 1 4 7 2, 5,6 Each resource unit cost $100; no quantity discounts are available. In addition, it costs $2 per unit per time period to hold this resource in stock, and it costs $45 just to place an order for materials (independent of the number of units ordered). When should each task in the project be started and when and how many resources should be ordered to minimize total project costs? 1. 1, en en 1. 2. en

The table below contains data for the installation of new equipment in a manufacturing process for a steel corporation. Your company is responsible for the installation project. Indirect costs are $6,000 per week, and a penalty cost of $10,000 per week will be incurred by your company for every week the project is delayed beyond week 15.

Image of Diagram included Using the diagram, find: The critical path. How long it will take to complete the project? How does simulation determine the probabilities of various project completion times? What is "slack" and why is it important? Why is activity-on-arrow (AOA) or activity-on-node (AON) of significant value to the project manager? How is the uncertainty in project scheduling dealt with? Should the critical path activities be managed differently from noncritical path activities? Explain.
1 Cara's clients, Emily and Dave, have just had a baby and she would like to do something nice for them. She signs them up for a baby registry that sends them a small gift. Emily and Dave will be sent information and service lists that are geared toward helping new parents. She provided their names, address and phone numbers so that they will not miss any of the activities provided in the package. Has Cara dealt with her clients appropriately? NUYLOTNQhObm1bEVKUTO90 a0 Cara did not protect her clients' privacy when she shared their personal information with the baby registry. O Cara should not make this a regular practice. Her clients will begin to expect gifts and she will not be able to sustain this. CO Cara should have set up an appointment to re-evaluate her clients' needs now that they have had a baby. 40 Cara's gift is very thoughtful and will help to build a relationship with her clients.
