TUI Network Architectures and Technologies Discussion

 

The evolution of WAN architectures has involved a variety of dominant designs such as T-1 and T-3 lines, which are still quite popular but do not meet high-traffic demands. Instead, Frame Relay and ATM are more commonly used to provide an interface to public high-speed switched networks. ATM, SDMS, and SONET are capable of handling voice, image, and data traffic concurrently. In addition, most ATM suppliers provide permanent virtual connections of dedicated time division multiplexing (TDM) channels to set up private networks.

1.Explain the differences between ISDN and IDN. How is ISDN accessed?

2.What is broadband ISDN? Compare and contrast the services used in B-ISDN.

CSC 340 TUI Networking and Data Communication Research Paper

 

The most widely used data communication service is Frame Relay, which was developed as part of the ISDN project. It can be used in private and public network configurations. Frame Relay uses variable size pockets or frames, and the process is simpler than X.25. Data rates of 2 Megabits can be achieved.

According to Forouzan, Frame Relay provides permanent virtual circuits and switched virtual circuits. For example, Frame Relay network can be connected to the Internet and internal LANs and WANs through the use of routers. Frame Relay WANs can be used as one link in the global Internet.

ITM 490 TUI Management Integration and Implementation Essay

 

MANAGEMENT INTEGRATION AND IMPLEMENTATION

In Module 4 SLP, we return our focus from the specifics of information technologies and the formulation of ideal strategies to the wider world of real corporate behavior. Our emphasis now shifts to the actual implementation of information technologies and the sociotechnical dynamics that implementation not infrequently founders upon. No technical solution—however brilliantly designed or competently backstopped or elegantly integrated with other corporate plans—is any better than its implementation at the lowest levels of the system to which it is addressed. All too frequently, plans and solutions are developed in a vacuum apart from the context within which they are to be deployed and used. It is hard to overestimate the quantity of corporate resources that have been squandered on poor IT implementations over the years—to say that it would exceed the GNP of many third world countries would probably not be an exaggeration. Implementation is by no means an all-or-nothing proposition; even though the full measure of system changes may not be as successful as desired, there can often be positive local results, particularly if the implementation process is oriented toward learning as well as doing, or even more so, doing unto others. The one sure way to implementation failure is to assume that all knowledge resides in IT management—or even in management generally. Success is inevitably based on user involvement in varying degrees, generally more rather than less.

All modules in the course draw on everything that you have learned in the program; however, this module most specifically draws on your courses in computer-human interaction, systems development, and project management as well as on your general introductory courses. Implementation is a drawn-out process requiring effective collaboration among many different kinds of specialists and generalists, extended over time and across space, and requiring explicit attention to both the social and technical systems of the organizational units affected. Above all, implementation must be sensitive to feedback, resilient enough to deal with changing circumstances, personnel, and goals, and focused much more on the users than on the technologists. Effective implementation always embraces the fundamental sociotechnical criterion of “incompletion”—that is, the idea that no change process is ever “finished” as such, but that change is an ever-flowing river in which one set of adjustments is merely the prelude to another set. Sociotechnical life in organizations is a soap opera, not a novel. There is never a “happily ever after,” just an ever-evolving and constantly reconfiguring cast of players and problems. Sometimes things get better; sometimes they get worse—but they will always be different.

Videos of Interest… Something to Think About…

Andrew McAfee discusses an array of revolutionary technologies that are replacing routine jobs with machines that can speak, understand, translate, and hear. McAfee believes that this kind of innovation will lead to creating new jobs that involve more than enhancing creativity. He refers to this cycle of innovation as “The New Machine Age.” Think in terms how technology-driven changes could impact the ERP implementation for Aux Bons Soins’ case study below.

TED Ideas Worth Spreading. (2012, September). Andrew McAfee: Are droids taking our jobs? Retrieved from http://www.ted.com/talks/andrew_mcafee_are_droids_…

For the last assignment, we will be introducing a new case, the real-world story of an ERP implementation for Aux Bons Soins. This case details the rather frustrating experiences that the company encountered in trying to implement an integrated management system after an acquisition and merger, and the range of circumstances that affected the process. Not every implementation is this sticky, but in varying ways most partake of greater or lesser parts of this experience. Please note that there is nothing particularly pathological about the experience described here, despite the frustrations experienced. There are no great villains, but neither are there any great heroes; implementation seldom turns up either. This may seem a rather inconclusive note on which to conclude both this course and your IT management program, but it is how things are. For better or worse, this is what real IT management is all about—the good, the bad, the ugly, and above all the reasonably acceptable. Over the next decades, the profession is likely to evolve far beyond any ways that can be reasonably forecast today; after all, 20 years ago there was not any such thing as the Internet, and today’s information environment was ranked science fiction. You are entering the profession at a most exciting and dynamic time; always remember how much you do not know, but also remember that you do know how to learn.

Please read the following parts of the case:

Use information from the course background readings as well as any good quality resource you can find. Please cite all sources and provide a reference list (use APA format) at the end of your paper.

Your answer to the following will be assessed:

  • What were the main causes of the difficulties with the project at Aux Bons Soins?
  • What were the key elements that led to the success of the project at Aux Bons Soins?

    HC Risk Management & Empowering an Organization Discussion

     

    1. Risk management is one of the most important components in empowering an organization to achieve its ultimate vision. With proper risk management culture and knowledge, team members will be “speaking” the same language, and they will leverage common analytical abilities to identify and mitigate potential risks as well as exploit opportunities in a timely fashion. In order to consolidate efforts, the existence of an integrated framework is crucial. This is why an ERM is necessary to the fulfillment of any organization’s goals and objectives. In your final research project for the course, your task is to write a 7-10 page paper discussing the following concepts:
      • Introduction – What is an ERM?
      • Why Should an Organization Implement an ERM Application?
      • What are some Key Challenges and Solutions to Implementing an ERM?
      • What is Important for an Effective ERM?
      • Discuss at least one real organization that has been effective with implementing an ERM framework/application.
      • Conclusion – Final thoughts/future research/recommendation

      The paper needs to be approximately 7-10 pages long, including both a title page and a references page (for a total of 9-12 pages). Be sure to use proper APA formatting and citations to avoid plagiarism.Your paper should meet the following requirements:

      • Be approximately seven to ten pages in length, not including the required cover page and reference page.
      • Follow APA7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
      • Support your answers with the readings from the course, the course textbook, and at least FIVE scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find supplemental resources.
      • Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.
