MIS2 - Assignment 9

The existing models of information technology (IT) acceptance were developed with the concept of the static individual computing environment in mind. As such, in today's rapidly changing IT environment, they do not serve as adequate indicators of an individual's IT usage behavior.

“The rate and magnitude of change are rapidly outpacing the complex of theories -- economic, social, and philosophical - - on which public and private decisions are based. To the extent that we continue to view the world from the perspective of an earlier, vanishing age, we will continue to misunderstand the developments surrounding the transition to an information society, be unable to realize the full economic and social potential of this revolutionary technology, and risk making some very serious mistakes as reality and the theories we use to interpret it continue to diverge." - Cordell (1987)

The three changes that likely to have substantial impact on USEP in the next three years are the following:

1. Electronic Processing of all services

Electronic Data Processing (EDP) can refer to the use of automated methods to process commercial data. Typically, this uses relatively simple, repetitive activities to process large volumes of similar information. For example: stock updates applied to an inventory, banking transactions applied to account and customer master files, booking and ticketing transactions to an airline's reservation system, billing for utility services. Its advantages are: speed, it operates the speed of electric flow which is measured in billions and trillionth of a second. It is faster than any other machine designed to do similar works; accuracy, high speed processing by computer is accompanied by high accuracy results the electronic circuitry of computer is such that, when the machine are programmed correctly and when incoming data is error free, the accuracy of the output is relatively assured; automatic operation, an electronic computer can carry out sequence of many data processing operations without human interaction, the various operations are executed by way of a stored computer program; decision making capability, a computer can perform certain decision instruction automatically; compact storage, electronic data processing system have the ability to store large amounts of data in compact and easily retrievable form; discipline imposes, to solve problem-with computer you must, first understand the problem, second, program the computer to give you right answers. Understand a problem is one thing but understanding it to the depth of detail and insight required to program the computer is a completely different matter.

2. Virtual Learning

A virtual learning environment (VLE) is a set of teaching and learning tools designed to enhance a student's learning experience by including computers and the Internet in the learning process. The principal components of a VLE package include curriculum mapping (breaking curriculum into sections that can be assigned and assessed), student tracking, online support for both teacher and student, electronic communication (e-mail, threaded discussions, chat, Web publishing), and Internet links to outside curriculum resources. Its advantages are: learning without any restriction as to time or space; courses based on modules with flexible time schemes, which take individual learning needs into account; and greater responsibility taken by students in the learning process.

3. RFID

RFID stands for Radio-Frequency IDentification. The acronym refers to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less. The RFID device serves the same purpose as a bar code or a magnetic strip on the back of a credit card or ATM card; it provides a unique identifier for that object. And, just as a bar code or magnetic strip must be scanned to get the information, the RFID device must be scanned to retrieve the identifying information. Its advantages are: RFID tags are very simple to install/inject inside the body of animals, thus helping to keep a track on them. This is useful in animal husbandry and on poultry farms. The installed RFID tags give information about the age, vaccinations and health of the animals; RFID technology is better than bar codes as it cannot be easily replicated and therefore, it increases the security of the product.; Supply chain management forms the major part of retail business and RFID systems play a key role by managing updates of stocks, transportation and logistics of the product; Barcode scanners have repeatedly failed in providing security to gems and jewelries in shops. But nowadays, RFID tags are placed inside jewelry items and an alarm is installed at the exit doors; The RFID tags can store data up to 2 KB whereas, the bar code has the ability to read just 10-12 digits.
