Case Study Cultivating Customers the Social Way

To most people, Facebook and Twitter are ways to keep in touch with friends and to let them know what they are doing. For companies of all shapes and sizes, however, Facebook, Twitter, and other social media have become powerful tools for engaging customers, amplifying product messages, discovering trends and influencers, building brand awareness, and taking action on customer requests and recommendations. Half of all Twitter users recommend products in their tweets. It has been said that social media are the world’s largest focus group, with consumers telling you what they want every single day.

About 1.3 billion people use Facebook, and more than 30 million businesses have active Brand Pages to develop “fans” of the brand by enabling users to interact with the brand through blogs, comment pages, contests, and offerings on the brand page. The Like button gives users a chance to share with their social network their feelings about content and other objects they are viewing and Web sites they are visiting. With Like buttons on millions of Web sites, Facebook can track user behavior on other sites and then sell this information to marketers. Facebook also sells display ads to firms that show up in the right column of users’ Homepages, and most other pages in the Facebook interface such as Photos and Apps.

Case Study Questions

10-15 Assess the management, organization, and technology issues for using social media to engage with customers.
10-16 What are the advantages and disadvantages of using social media for advertising, brand building, market research, and customer service?
10-17 Give some examples of management decisions that were facilitated by using social media to interact with customers.
10-18 Should all companies use Facebook and Twitter for customer service and marketing? Why or why not? What kinds of companies are best suited to use these platforms?

● The body of your document should be at least 1500 wrds in length.

●  Please, in a Microsoft Word document, must cite and reference at least 4 credible sources.

 APA format is required.

 Discuss the principles of ethics and medical professionalism in strategic planning.

 Examine the role of leaders in ethical decision-making and problem solving strategies in the U.S. health system.

Unit 8 Assignment Case Study:   Problems at the V.A.  Health System

In 2009, President Barack Obama appointed retired Army Chief of Staff, General Eric Shinseki, to the position of secretary of Veterans Affairs (VA), the federal department responsible for providing healthcare and federal benefits to U.S. veterans and dependents. As part of its strategic plan, Secretary Shinseki was tasked with implementing 16 major initiatives to bring the VA into the 21st century. One of the 16 initiatives was the enhancement of the veteran’s experience with and access to healthcare.

In 2013, CNN was among the news outlets reporting that veterans were experiencing delayed care at the Williams Jennings Bryan Dorn Veterans Medical Center in Columbia, SC. In fact, the delays were so serious that six veterans died while waiting for months to receive necessary diagnostic procedures. The VA launched an investigation into the GI clinic at Dorn and found several issues, including low staff census; leadership turnover that resulted in a lack of understanding of roles, responsibilities and system processes; and ineffective program coordination. Allegations of long wait times also emerged from VA facilities in Arizona, Pittsburgh, and the Phoenix VA Health Care System. Delays, however, were not the only shortcomings alleged. In the Phoenix VA Health Care System, for instance, there were claims of manipulated patient wait times, bad scheduling practices, and patient deaths.

In 2014, the Office of the Inspector General (OIG) launched an investigation into these allegations. Two questions were addressed in this review:

1. Did the facility’s electronic wait list (EWL) purposely omit the names of veterans waiting for care and, if so, at whose direction?

2. Were the deaths of any of these veterans related to delays in care?

3. The investigators confirmed “inappropriate scheduling issues throughout the VA and health care system” (VA 2014, iii).

In the Phoenix VA, specifically, investigators found that 1,400 veterans did not have a primary care appointment but were listed on the EWL. It was also determined that 1,700 veterans were waiting for a primary care appointment but were not listed on the EWL. Because veterans were not on the EWL system, the Phoenix leadership significantly understated the time new patients waited for the appointments. The investigators found that the average wait time was 115 days for the first primary care appointment and about 84 percent of these patients waited more than 14 days.

The Office of Inspector General (OIG) identified multiple types of scheduling practices that were not in compliance with Veterans Health Administration policy. Since the multiple lists found were something other than the official EWL, the additional lists may be the basis for allegations of “secret” wait lists.

- Secretary Shinseki called the findings “reprehensible” and resigned from his post on May 30, 2014.

  Case Study Questions:

 1. From a leadership perspective, analyze the problems at the VA relative to ethical decision making practices.

 2. Discuss the ethical issue of having 1,700 veterans, who were not listed on the EWL, wait for a primary care appointment at the Phoenix VA. NEED AT least two (2) policies/standards to ensure ethical leadership practices with respect to improving coordination of the EWL and primary care appointments.

3. Explain why Secretary Eric Shinseki resigned his position. Identify at least two (2) alternative options that Secretary Shinseki could have taken to resolve the unethical decision-making practices in this case study.

4. Apply the American College of Healthcare Executives (ACHE) Code of Ethics to the VA Health System case study.

IT 315 Final Project Part I, II AND III

IT 315 Final Project Part I, II AND III Milestone One Guidelines and Rubric

IT 315 Final Project Part I Milestone One Guidelines and Rubric

Overview: Throughout this course, you will develop the skills required of a software architect—a role that is in high demand in the software industry. The final project resembles a typical development project of an actual software designer or software architect. You will have the opportunity to apply, practice, and receive feedback on how software systems are designed using object-orientation and Unified Modeling Language (UML) modeling.

For this assessment, you will assume the role of a consultant tasked with designing a student information system (SIS) for a small college that offers both online and face-to-face classes. The SIS should keep track of students’ information and their course registrations. You will be provided with information about the system, its business context, and its requirements. With this information, you will need to design the software system by applying object-oriented techniques and methods and UML modeling.

Specifically, this final project is divided into three different parts, which will each be submitted separately. Each part focuses on a different stage in the development process, and will be completed in sequence throughout the course. Additionally, at each stage you will validate and verify your design, explain how you arrived at it, and reflect upon your process and lessons learned. Through the milestones, you will have an opportunity to gather feedback first before you submit final versions. The three final project submissions are Part I: Functional Model, submitted in Module Four; Part II: SIS Structural Model, submitted in Module Six, and Part III: Behavioral Model, submitted in Module Eight.

Prompt: The Student Information System Requirements Definition document is the requirements definition document of a new SIS for a small college. The college offers both online and face-to-face, brick-and-mortar classes to its undergraduate student population.

The goal of the SIS is to maintain and track the college’s information about its students, courses, and classes. The SIS is also used to automate the class registrations process. The SIS system should be accessible as a website and as a mobile app to both students and enrollment staff.

You are hired as a consultant software architect to design the SIS functional model consisting of the following:

· A use case diagram

· A use case description for each use case in your model

Analyze the SIS requirements and formalize them as use cases. You should have between four to six use cases. Generate a use case diagram showing the actors associated with each use case, and structure your use cases using <<include>>, <<extend>>, and generalization relationships. The use case diagram must be generated by a UML drawing tool such as or Visio.

Using the Final Project Part I Solution Submission Template document, provide a description for each use case in your use case diagram. Use this same document to complete and submit your deliverables. Your functional model should be complete and professional.

IT 315 Final Project Part II Milestone One Guidelines and Rubric

Based on your SIS functional model, create an SIS structural model consisting of:

· A class responsibility collaboration (CRC) card for each class in your model

· A class diagram

From the SIS functional model, identify the classes of your structural model. You should have between six to nine classes. Using the provided Part II Solution Submission Template document, document each class showing its responsibilities, collaborations, attributes, and relationships.

Formalize the information from the CRC cards into a class diagram. Your class diagram should use the class relationships of association, generalization, aggregation, and composition to structure the classes and should indicate the multiplicities of these relationships. The class diagram must be generated by a UML drawing tool. After creating your model, make sure to complete the other deliverables listed below.

Links to UML drawing tools:


· Visio

IT 315 Final Project Part III Milestone One Guidelines and Rubric

Based on your SIS functional model and structural model, create an SIS behavioral model consisting of the following:

· A sequence diagram for the Register a Student for Classes use case

· A communication diagram for the Register a Student for Classes use case

From the SIS functional model, Register a Student for Classes use case, and the structural model, identify the objects and the actors that participate in either the sequence diagram or the communication diagram. Identify the messages that are sent and received among these objects and actors and determine the order of message passing. Formalize your findings as a sequence diagram and a corresponding communication diagram. For the sequence diagram, show the execution occurrence when a message is sent or received. Both the sequence diagram and the communication diagrams must be generated by a UML drawing tool.

Links to UML drawing tools:


· Visio

Using the Final Project Part III Solution Submission Template document, provide a description for each use case in your use case diagram. Use this same document to complete and submit your deliverables. Your behavioral model should be complete and professional.

Specifically, the following critical elements must be addressed:

· Creation: From your functional model and structural model, create a UML behavioral model showing how objects from the classes of the structural model collaborate to implement the use case behaviors described in the use case descriptions. Your behavioral model should include at least a UML sequence diagram and UML state machine diagram. The behavioral model should clearly identify the methods of each class that are needed for the collaboration in each use case. Provide a method contract and method specification of at least two methods of your sequence diagram.

· Testing: Verify and validate your behavioral model against the structural model and functional model of the SIS system.

· Approach Explanation: Explain your approach to creating your behavioral model and the design decisions you made to create it.

· Self-Reflection: Discuss your experience creating your behavioral model and the lessons you learned from it. Specifically, draw connections between your experience and the object-oriented techniques and methods discussed in this course.

Guidelines for Submission: Use the Final Project Part III Solution Submission document and follow the formatting directions therein when submitting your work. Your behavioral model should be complete and professional.

Instructor Feedback: This activity uses an integrated rubric in Blackboard. Students can view instructor feedback in the Grade Center. For more information, review these instructions.
