Project #12132 - Enterprise Application

The assignment needs to be at least 2 paragraphs or 1 page. 

 

Chapter 5, which you read last week, is focused on the IT foundation needed to support management information systems (MIS). In Ch. 1 (p.11), this concept of MIS was introduced to explain how companies are dependent on turning data into useful information to support decision making. This knowledge derived from the information helps companies adjust their strategy, if needed, to meet changing environmental factors – such as new competition, threat of substitute products, changes in customer preferences, etc. Chapter 5 also contains a lot of information regarding the concepts to help you develop an understanding for the inter-relationships of hardware, software, and services as well as the many management issues that must be considered when selecting and deploying new technology. Understanding the basics of these components and how they inter-relate is useful for managers as they identify IT solutions to support business problems.

 

While the continuous growth in the power of IT provides an opportunity for new business models and processes, the management challenges of making sound investments (understanding the total cost of ownership), addressing issues of scalability (the ability to expand as the numbers of users increase), changes in technology, along with appropriate management and control are critical issues that take a skilled management team to effectively address. Investments in technology do not guarantee the viability and profitability of an organization. The competitive forces model (shown below) illustrates the six factors that need to be considered when looking at how much your organization should spend on IT infrastructure. Too often firms may get swept up on the latest technology and adopt a solution that is not a good fit for the organization. The economic losses in such a situation include not only the expenditures of hardware and software but also the time spent implementing a failed solution--this can include the time to redefine business processes, train employees, and other complementary assets.

As pointed out on p. 170 in the text, the MIS infrastructure supports operations, change and sustainability of the organization. The components and characteristics shown in the chart are the foundation upon which business will implement different enterprise systems, decision support tools, and other software applications to solve business problems. In summary:

   Information MIS Infrastructure – management of information required to support operations, including elements of disaster recovery and business continuity planning.

   Agile MIS Infrastructure – "includes the hardware, software, and telecommunications equipment… to provide the foundation to support the organization's goals." (p. 170) When considering infrastructure agility, one must consider factors such as accessibility, availability, maintainability, portability, reliability, scalability, and usability.

   Sustainable MIS Infrastructure – technology support for organizational growth and the pursuit of more efficient operation and environmental awareness. Advanced technologies such as grid computing, cloud computing, and virtualization play important roles in this area.

The text lists seven primary characteristics of agile MIS infrastructure (the “ilities”):

1.Accessibility

2.Availability

3.Maintainability

4.Portability

5.Reliability

6.Scalability

7.Usability

In addition, there are three aspects of IT security that you will need to understand to complete your Stage 3 project:

1.Authentication & Authorization

2.Prevention & Resistance

3.0. Detection & Response

 

For this week's conference, each member must select one of the ten characteristics above and respond with an example of what this term means in terms of IT architecture and why it is so important to a solid architecture to support MIS. These terms can be applied to other aspects of IT and business in general, but the focus here is on IT architecture. Some additional research will provide specific examples including what companies have focused on in these areas. Simply typing "IT Scalability" (or whatever characteristic you select) into your web browser should provide good results, but be sure to evaluate the sources to make sure they are relevant to this discussion. Remember to distinguish between objective articles and vendor's marketing information.
