CONTINUING PAYROLL PROBLEM • A
Refer to the partially completed payroll register which you worked on at the end of Chapter 3. You will now determine the amount of income tax to withhold for each employee, proceeding as follows:
1. In the appropriate columns of your payroll register, record the marital status and number of withholding allowances claimed for each employee, using the information provided.
2. Record the payroll deductions for the SIMPLE plan that the employer has established for participating employees. All of the employees are participating, and their weekly contributions are listed below. The tax deferral on these deductions applies only to the federal income tax.
3. Record the amount of federal income taxes using the wage-bracket method.
4. Record the state income taxes on the gross weekly earnings for each employee. The rate is 3.07% for the state of Pennsylvania.
5. Record the city income taxes on the gross weekly earnings of each employee. The rate is 3% for the city of Pittsburgh residents.

Ask if his or her organization uses any of the project human resource management features described in this chapter and Appendix A, and document the reasons given for using or not using certain features.

Go to YouTube™.com and search for “team building” or use any other resources to find
information. You are required to find at least two “team building” videos or other resources.
You will need to be able to contrast and compare the two videos or resources.
After viewing the video or other resource answer the following questions in a Word
document .
What type of team building concepts does the videos/resources promote? What type
of team dysfunctions does the video/resources address?
Do the videos/resources employ techniques you believe would benefit or enhance
team performance? Why or why not?
Have you experienced this type of team building within your organization? If so, how
did it work? If not, do you believe this type of team building would work within your
organization? Why or why not?
Do you believe one technique is better than the other? Why or why not?
How would you employ this technique within your organization? What changes would
you adopt? Why or why not?
Requirements Two different team building methods should be researched and discussed. The two
team building methods should be contrasted within the paper utilizing and
addressing each one of the above questions. The paper should be at a minimum
1000 words.

Network Security and Management Activities

1. Identifying Threats

Create a sample inventory of five main information assets in the company. Please follow the example in Figure 11-4 in the textbook. Complete the inventory of assets table provided in the Project Milestone 5/Network Security and Management page of the project template.

2. Threat Scenario and Control

For any one of the assets identified in inventory of assets table, identify possible threats and create a threat scenario and control table provided in the Project Milestone 5/Network Security and Management page of the project template. Please refer to the examples provided in Figures 11-6 and 11-7 in the textbook to guide you in completing the table.

The memory chip manufacturer, having identified the appropriate location for its major production facility, now wants your team to determine the optimal internal layout for the facility based on the following criteria:

The facility will manufacture several lines of memory chips, some with compatible components and some that do not have compatible components.

The facility will also house an administrative support workgroup that will receive and process orders, bill customers, and provide payroll/HR support for the local workforce.

The facility will also be responsible for shipping to national, international, and local customer locations.

Assignment #1: There are 4 types of potential layouts: product-based, functional, cellular and fixed-position layouts. Define each of the listed layouts from an academic context and specify how it might apply to the company’s facility.

Part #2

Deliverable Length:  1 – 2 pages in APA format

Assignment #2 Justify your and choice for the most appropriate method for the company.  Determine the most appropriate optimization models of the chosen layout(s). In other words, identify the best methods that the company can use to optimize workflow amongst those methods (individual layout types). Provide a full rationale.

A large, fast-food chain unveiled a new touch screen register for its franchises. Each cashier was assigned a user id and password combination to log in to the register. The system allowed the incorrect password to be entered four (4) times before the register would lock and require a manager to unlock it with a key card. To prevent unauthorized access, the registers would lock after three (3) minutes if the screen was not touched. When the register locked, only the cashier who was logged in prior to it locking could unlock it without a system restart.

After a few days in operation, restaurant managers started complaining about the amount of time they were spending unlocking the registers. Some cashiers were forgetting their user Id and password, so other cashiers would log in for them. It also seemed that the button layout made it easy for the cashiers to key in the incorrect password. The managers also complained that cashiers would leave for a break or end their shift and forget to log out of the locked register. The managers would have to reboot the system, a three to five (3-5) minute process in order for the next cashier to log in. Additionally, managers noticed that grease was building up on the touch screens, making them less responsive.

Write a five to eight (5-8) page paper in which you:

1. Analyze the new system and determine the design issues with this new system.

2. Describe how you would correct the design issues with the system to make the restaurant managers happy.
3. Create a design plan that:
   1. Lists and explains the tasks associated with improving this interface.
   2. Contains at least six (6) tasks.
   3. Includes realistic time estimates for each task to be completed.
   4. Analyzes the development of the system in your plan.
   5. Analyzes the testing of the system in your plan.
   6. Analyzes the implementation of the system in your plan.
4. Examine how this system balanced security and usability, and explain the challenges of incorporating system security and system usability into a design.
5. Suggest changes that could be made to the security of this system to still meet security objectives but make the system more usable.
6. Use Microsoft Visio or an open source alternative, Dia, to create a graphical representation of your proposed interface. Note: The graphically depicted solution is not included in the required page length.
7. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

Your assignment must follow these formatting requirements:

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
• Include charts or diagrams created in Excel, Visio, MS Project, or one of their equivalents such as Open Project, Dia, and OpenOffice. The completed diagrams/charts must be imported into the Word document before the paper is submitted.
