DB 1 Leadership and Ethics

 

Provide an example of when a person (boss, coworker, peer) really expected you to either perform well or fail and treated you like you would, which resulted in your success or failure…. “Do ethics matter?”

 

DB 2 Case Study PF Chang

 

Based on the video below, in what ways does PF Chang’s create organizational commitment among its workers? How might a manager at PF Chang’s use the Big Five personality factors to assess whether a candidate for a position on the wait staff would be suitable?

ANSWER THE ABOVE QUESTION AND THEN REPLY TO MY CLASSMATE RESPONSE TO THE ABOVE QUESTIONS AND EXPLAIN WHY YOU AGREE? (A MINIMUM OF 150 WORDS EACH)

 

 There was an incident I had with the head of my division at a previous job. He thought I was going to fail at meeting a deadline for a project we worked on. He kept interrupting and criticizing me but he didn’t have any idea how the project was supposed to be completed because that wasn’t his area of expertise.  He just wanted it done on time. Aside from all of his verbal abuse, which was something he did on a regular basis, I was able to complete the project on time with no errors. Since we were in the same unit and the project was to benefit the agency, it would have been good to have received some assistance and positive reinforcement. I was very happy when I was able to find employment with another agency.

 

Ethics matters. Our course material tells us that the golden rule of ethics is to lead others as you want to be led and that there is a direct link between being ethical and being an effective leader. People with positive attitudes about ethics tend to be more ethical. I feel that my supervisor could have had a better attitude and been more supportive to all of us in the office. His negative attitude was not beneficial to the unit and certainly did not contribute to building goodwill amongst the staff.

 

DB 2: Case Study PF Chang

 

After watching the video, I can see that PF Chang is a great place to work. The managers are caring and it shows in their positive attitudes. They encourage their staff not to just see their job as “just a waiter” and just give mediocre service but to really interact with the customers and make it a great experience for them as well as the customer. The managers have a pre-shift meal with the staff to encourage and motivate them to have a great attitude on the job so they will want to provide the customers with a higher level of service that they won’t forget,  which inevitably can lead to bigger tips. This will also make them want to come again which is great for business.

 

One way the Manager’s at PF Chang can use the Big Five personality factors to access whether a candidate for a position on the wait staff would be suitable would be during the interview to do as  Mark Miller, Operating Partner at PF Chang, does: get them to give specific answers about personal experiences that may have been negative and how they were able make it positive.  Get them to share their personal experiences with you about how they dealt with former employers, guests and fellow employees and you will get a better idea as to whether or not they will fit in with your business based on their answers. A candidate with a positive attitude is a definite win for any company.

Laws and policies are much needed in our society as they help in maintaining law and order in the society and help in shaping political and social aspects of the society. Though policies and laws can be interrelated, they are definitely two terms having different purposes (Gau, 2018).   No nation can go forward without having certain laws and policies. A policy is that which outlines what a government is going to do and what it can achieve for the society as a whole. Policy also means what a government does not intend to do. It also evolves the principles that are needed for achieving the goal. Policies are only documents and not law, but these policies can lead to new laws. Laws are set standards, principles, and procedures that must be followed in society (Kozlowski, Glazener, Mitchell, Lynch, & Smith, 2019). Law is mainly made for implementing justice in the society. There are various types of laws framed like criminal laws, civil laws, and international laws (Gau, 2018). While a law is framed for bringing justice to the society, a policy is framed for achieving certain goals.

 

A project can be described as one-off operation that has certain objectives and required to be met within stipulated time. A project represents a single effort. It is a group of people forming a team working towards a common goal. A program is different it is a collection of projects. Together all the projects form a cohesive package of work (Gau, 2018). The different projects are complimentary and help the program achieve its overall objectives.  A project differs from a program in the sense that the latter is a bundle of related projects, managed in a coordinated manner, to attain the benefits, which is available only when the projects are managed in groups (Kozlowski, et al., 2019). There are many people and employees who misconstrue project for the program,

Course Scenario

 

Oil Company X is a large oil refinery which has been expanding and  taking on new investment projects. Recently, they have considered  building a pipeline that stretches across the United States, from Canada  to New Orleans.

 

This particular process will generate high revenues, but also high  costs. The expected profit generated from the initial investment after  10 years will be approximately 8%. Assume that stocks tend to average a  return of approximately 10% over a 10 year period.

 

Recently, the CEO has faced backlash from the company Board who  have asked specific questions concerning the recommendations put forth  by the Cost Analysis Department. The Cost Analysis Department has  indicated that the marginal analysis does not support the project.   However, the Board feels that this would be a profitable project due to  the massive revenues that would be generated. They have questions in  relation to marginal analysis, and how it is undertaken. As a Cost  Analyst, you have been asked to make a presentation to the Board.

 

Instructions

 

The head of the Cost Analysis Department has asked you, a recent  hire, to make a presentation to the Board explaining your  recommendation. You will provide the Board with an introduction to  marginal analysis used by the company when making investment decisions.

 

Your PowerPoint should include narration as you make your presentation to the Board.

 

Your presentation should justify your Department’s recommendation  not to undertake the project. This should include an explanation of the  following terms and how they relate to the department’s decision:

 

1. Opportunity Cost
2. Marginal Benefit
3. Marginal Cost

 

There are many free screen recording software/Webware options  available (such as Screencast-O-Matic) to use in presenting your  PowerPoint. Make sure that both your voiced narration and the PowerPoint  slides are captured during your screen recording.  

 

– Don’t do the recording, just put in reference what should be presented for each of the slides as a memo and I can complete the recording.

 

Pay attention to your audience. Remember that you are explaining  the concepts of marginal analysis and opportunity cost to someone who  may have no previous knowledge of economics.

A. Using the Internet, review at least 3 articles on Profit-Cost-Volume relationship. Summary (300 words or more) the articles in your own words.

 

B. As a manager, why is Profit-cost-volume important in planning? Support your response with numerical example(s)

D. As a manager, discuss how you would use Variable Costing in managerial decisions Support your response with numerical example(s)

Technical Paper: Proof of Concept (POC)

 

Due Week 10 and worth 230 points

 

Your company is a 4-year-old startup called XYZ Software Enterprises. XYZ produces a point of sale system and was awarded a Proof of Concept (POC) to one of the largest and oldest restaurants in the industry (you know, the ones in the commercials all the time). The restaurant wants XYZ to prove that the software will do what the sales people said it could do.

 

Your Proof of Concept will include four parts:

 

· Part 1: Gantt Chart

 

· Part 2: Testing and User Acceptance Report

 

· Part 3: Use Case Diagram

 

· Part 4: Activity Diagram

 

Part 1: Gantt Chart

 

A Gantt Chart (see page 353 Figure 11-18) needs to be created for the entire process of the Proof of Concept. There is a two-month deadline from today to complete the POC.

 

Using Visio or Excel, create a Gantt Chart that includes all of the items listed below and adds five more tasks minimum from the concepts learned from the course:

 

· The initial meeting — today.

 

· Should appear as the first line.

 

· Teams selected to participate in the project (1 week).

 

· Information gathering (add the information gathering methods you will use and how long each will take).

 

· System configurations based on information gathering methods (2 weeks).

 

· Create Activity Chart based on information gathering (info to create chart supplied).

 

· Create Use Case Diagram based on information gathering (info to create chart supplied).

 

· Show the finished configurations to the team and get feedback (1 day).

 

· Make changes based on feedback (3 days).

 

· Install the system in the test store (2 days).

 

· Train staff (1 day).

 

· Run a live test of POC (2 weeks).

 

NOTE:

 

· The five or more additional tasks can be subtasks for information gathering methods as well some other subtask or major task not in the initial list.

 

· You may add items from the SDLC, specific item(s) on testing, or any other concept you think should be part of the POC process learned in the course of this semester.

 

NOTE: Remember that events in a Gantt chart can happen at the same time as other events. Some items also cannot start until others are completed. Everything has an estimated timeframe and it is displayed in the chart.

 

 
 

 

Part 2: Testing and User Acceptance Report

 

As part of the expected documentation in the POC, XYZ wants a report on Testing and User Acceptance.

 

Your manager is asking you to research the testing criteria they listed in the POC documents.

 

The POC document states that they are looking for:

 

1. System and Stress Testing

 

2. User Acceptance Testing (UAT)

 

For both categories, research and report on:

 

1. What these tests are.

 

2. Why the industry leader would want these particular tests.

 

3. The best ways, in detail, to accomplish the tests so that your company meets the criteria they are looking for.

 

o These items can be added to your Gantt Chart (Part 1)

 

Part 3: Use Case Diagram

 

The restaurant, as part of the information gathering, outlined a use case in a chart (below).

 

Your manager assigned you to create the Use Case Diagram using Visio, MS Word, or any other software. (See the diagrams on Page 84 and 85 of the textbook.)

 

· Paste the diagram into the created report.

Between 200 and2016, the US experienced remarkable changes internationally and domestically. By any measure, the terrorist attack of Sept. 11, 2001, was a game changer. With that a long, still-ongoing “war on terror” began that meant military engagements overseas and increased domestic security measures. In 2008, remarkably, the US elected its first African American president, Barack Obama. He was elected to a second term in 2012.

 

 

 

Discuss the following topic related to American history under President Obama:

 

 

 

1. Discuss president Obama’s election and presidency. (Considering our many explorations of race relations and Civil Rights in our history, there is much that can be said of President Obama’s election and presidency, and it is still perhaps too early to evaluate fully.)    
   • Identify two specific examples that you think were the most important developments of Obama’s presidency.
   • Explain why you chose those two examples.
   • Identify the source(s) where you read about these changes of the early 21st Century.

• Go to BizFiling’s website and read the article titled “Identifying and Addressing Employee Turnover Issues,” located at http://www.bizfilings.com/toolkit/sbg/office-hr/managing-the-workplace/employee-turnover-issues-tactics.aspx. Next, examine your current job position or a job position with which you are familiar. Then, choose three (3) significant factors that you believe have contributed to employees leaving the organization. Next, suggest three (3) methods organizations could utilize to retain their employees. Support your rationale with two (2) examples of such factors / methods.
• Based on the case study Retention: Deciding to Act (Pg. 735 – Pg. 737), determine whether the major complaints presented in the case study are the true reason for Wally’s Wonder Wash’s high turnover rate. Then, suggest two (2) reasonable retention strategies that Wally’s Wonder Wash could implement. Justify your rationale. Note: Remember, turnover is not always about salary. Therefore, please present strategies that would not involve pay increases.
