Advantages And Limitations Of Mobile Applications Information Technology Essay

Advantages And Limitations Of Mobile Applications Information Technology Essay Mobile applications are a quickly emerging section of the overall mobile market. These applications are made up of software that runs on a mobile device and carry out specific tasks for mobile phones and Pocket PCs. The focus of this paper is to describe the business advantages and limitations of the Best Buy Geek Squads wireless Pocket PC mobile devices and how they overcame those limitations. Additionally, describe the software development challenges of wireless mobile devices and how Medstar Health and Unifi met those challenges. Lastly, identify the advantages and limitation of companies using software packages already unavailable for use with wireless devices. Best Buy Background For many of todays businessman, Pocket PCs have become like another appendage. While there are some definite advantages to carrying a Pocket PC, its easy to overlook some of the obstacles associated with conducting business on them. The Geek Squad is an ancillary of the Best Buy Company which is headquartered in Richfield, Minnesota. The company offers a variety of computer-related services for both residential and commercial customers. Geek Squad agents provide both in-store, on-site services, as well as, Internet, and additionally also provides 24-hour telephone and emergency support. Best Buys agents are equipped with Sprint PPC-6700 Smart Devices, a Pocket PCs/cell phone combination that run on Windows Mobile 5.0 (OBrien Marakas, 2008). Advantages and Limitations There are many advantages to the Geek Squad Agents using the Sprint PPC-6700 Smart Device. One advantage is that these devices have full access to Sprints EV-DO third-generation cellular network, and have complete Web browsing capabilities (Geek Squad, 2010). When an agent is on the road and needs directions to his next job, he can quickly access Google or Yahoo maps and easily navigate to his destination, rather than having to fumble around with a map or to call back to Best Buy dispatchers. Additionally, agents can use their wireless devices to log onto Best Buys order system where they can obtain price quotes, process payments, complete transactions, and generate receipts for the customers. As with most devices, the Sprint PPC-6700 does have a down side. The problem the Geek Squad agents are having with this device is the small slide-out keyboard. The small keyboard limits their ability to type quickly and accurately, therefore wasting precious time (OBrien Marakas, 2008). Overcoming Limitations Along with battery life, inputting text is one of the most difficult problems for users of mobile devices. First and foremost, the problem is lies in the physical size of the keyboard, followed by the conflicting needs of speed and familiarity. As wireless data services flood into the market, the need for efficient text entry is becoming ever more critical, yet essential tradeoffs limit the practical options. Best Buy solved its problem with the Sprint PPC 7600 with the use of handwriting recognition software. Handwriting recognition is a method by which a computer system can recognize letter, characters and other symbols written by hand in ordinary handwriting. This type technology is generally used on devices such as PDA and Pocket PCs where a stylus is used to write on a screen, after which the computer program converts the handwriting into digital text (Handwriting Recognition, 2009). Geek Squad agents can hand write notes that go directly into Best Buys order system to be used a reference for later transactions. The next time a customer calls in with a problem, the agent can quickly pull up his notes for quicker and more reliable customer service. Prior to this technology, agents would have to wait until they got back to the office to enter the customers information into the system. According to one agent, it saves them 10-15 minutes that could have otherwise been spent helping a customer or traveling to the next job (OBrien Marakas, 2008). Although this is a big improvement, Best Buy is not fully content with the limitations of the current handwriting recognition software. They are now testing voice recognition software will permit agents to open and close programs with voice prompts allowing for quicker and better customer service. Voice recognition is a computer technology that uses audio input for a means of entering data instead of the using a keyboard. Speaking into a microphone delivers the same result as typing words physically with a keyboard. Vo ice recognition software is constructed with a database of identifiable words or phrases. The computer program matches up the voice audio signature with the equivalent entry in the database (Voice Recognition, 2009). Although, changing speech into text might sound simple, it is enormously difficult. The problem starts with an almost infinite assortment of speech patterns and accents, compounded by the tendency for people to run words together or the use of slang words. Software Development Challenges Mobile systems and mobile applications have gained a lot of attention both in research and industry over the last years. The market share of mobile devices is constantly growing. More and more, users expect their mobile devices to provide functionality similar to the one they know from their desktop computers, but also to provide additional, mobile device specific functionality, like location based services. However, software development for mobile devices is still cumbersome and a methodology geared towards supporting the development of such mobile applications is still lacking. One key factor for the commercial success of mobile devices is the quick development of software applications (Software Challenges, 2010). On the other hand, developing mobile software can be especially difficult since applications need to be conscience of and adapt to changing resources such as battery life and bandwidth. At one point in time it appeared like some standardization might occur and a common platform emerge, but most attempts have stumbled, and ultimately come up short of the ideal they set out to accomplish. None of these approaches were specifically at fault. They each simply met a specific set of needs during which the evolution of mobile devices that made the best of existing hardware and bandwidth limitations. The problem that each of them faced was the speed of evolution of mobile technology (Grotnes, 2009). It is true that mobile devices are still restricted by screen size, lack of a full size keyboard, and limited bandwidth. But there are already plenty of mobile devices with readable screens, 3D graphics, touch screens, accelerometers, compasses, and GPS capability. The functionality is in place for some outstanding state of the art applications and for smart developers to exploit. On the other hand, there is little standardization as hardware manufacturers struggle to get the best out of their devices (Grotnes, 2009). Conquering Challenges MedStar Health is a non-profit healthcare organization that is facing similar software development challenges. MedStars IT department supports thousands of nurses and doctors, who use a multitude of mobile devises such as Pocket PCs, PDA, Blackberrys, and Palm Treos. Since there is no clear cut leader in mobile technology, it is hard for MedStars IT Department to push for a standard device. Because MedStars nurses and doctors are not forced to use a standard device, it is difficult for their IT Department to keep up with new mobile devices and ensure they are compatible with the companys applications. To overcome these challenges, MedStar thought outside the box and worked with vendor to tailor applications that would work on a wide range of devices. MedStar chose to work with Siemens Medical Solutions and came up with a software solution that allows medical practitioners to access their patients information through Siemens Invision mainframe using any of their mobile devices. This t ype of thinking by MedStars IT Department allowed the company to meet its goals without having to sacrifice any functionality. Many times off-the- shelf applications will not meet the needs of a customer and may require some tweaking by the manufacturer to accommodate its customers specific needs. Conclusion A management information system is a system or process that provides information needed to manage organizations effectively (Computer and Information Systems Managers, 2010). As with the case of Best Buy and MedStar, their overall strategies were affected by MIS. Best Buy chose to use standard mobile devices and off-the-shelf applications to meet both its customers and employees needs. Whereas MedStar, decided it was better for them to develop specific software to overcome their challenges. Neither way is right or wrong, it just depends on your specific situation and needs. In a slowing economy, MIS strategies would definitely have to be reevaluated to ensure the organization is being managed effectively. In the case of MedStar, I would opt for the strategy the Geek Squad took with standardizing mobile devices and using off-the-shelf applications. In a slowing economy, this would save a considerable amount of time and money not having to develop software that is compatible for a mult itude of different devices. Additionally, a smaller IT Department could be utilized, saving thousands of dollars in nonessential personnel.

Are Test Scores a Good Indication of a School’s Competency? Ever studied for a test and still manage to receive a failing score? It happens to almost all of us. Schools may effectively or ineffectively design study material for a chapter, but to me it does not have a big effect of the overall resulting test scores. A high grade average depends on the students’ method of studying and comprehension, the way that the instructor teaches the material, and the way that the test it produced. On numerous occasions, students have reviewed specific test material and gained plenty of confidence for success, but failed with the most horrifying score of their life. On the other hand, some students may choose to cram as much as they can right before taking the test and excel. Every student has a different level of comprehension; some may learn faster than others, or be a different type of learner. Normally, students will be informed of an approaching test, this way each student know to more attentive during class time and while studying. The amount of tine that one has to prepare for an upcoming test varies. That length of time may be brief or extended. Because of the fact that every student is different, the time they may require to study effectively varies. I personally need about a week’s worth of study time to retain most of the appropriate information. Some may only need a few days. This can sometimes be a reflection of the way the material has been taught to a stud ent. For effective education retention, a study plan must be well-organized and taught thoroughly. Some instructors become lackadaisical causing the students to not be fully prepared for a final test while depending solely on that professor’s teachings. No matter how organized and thorough a lesson plan is designed, if the material is not taught right, the scores will not be right. Students should not depend only on the professor. They should combine what is taught to the with their own study method so that they can comprehend. A lot of times, students will believe that attending class and paying attention is enough which is false. They can be taught one way and be tested on it the subject in another form. Often times, students may say, â€Å"that had nothing to do with what I studied  all week for.† From my past experiences, I would study diligently for a test and find that the test asks questions that were not given examples of in the study material. That has to be one of the most frustrating things for a student. If schools were to have tests contain more of what was taught to the students, there would be a higher test grade scale. By this I mean that tests should ask similar questions that the homework asks or that were given in examples. I am sure that many can relate to a test asking questions that they have never seen. To sum it all up, the end result of a test depends on how much effort is put forth from the student, the student’s comprehension level, and the effectiveness of the instructor’s teaching method. There may be an A student who experiences test anxiety, this can cause low testing scores. There may be a student who cheats, of course, this mainly results in higher scores. There also may be a student who just happens to be a great test taker. Test scores are not a good indication of a schools competency.

Ethical Dilemma - 1463 Words

Ethical Dilemma PlentErgy is an openly traded oil and gas exploration company with operations mostly in Texas and Oklahoma. We do not want to miss the oil exploration in North Dakota. We are highly skilled in hydraulic fracturing or fracking, which is a technique that is used to release oil and gas from rock formations. We are confident that we could use fracking safely to release oil and gas from sites in North Dakota. The ethical dilemma that stands in the way is fracking is closely linked to waste disposal. Millions of galloons of salty, chemical infused wastewater, know, as brine is part of fracking. Oil companies are dumping and spilling the waste onto the land and waterway with increasing regularity. They are supposed to put the†¦show more content†¦With the hundreds of thousands of galloons of brine that is spilled every year and that number is increasing with more oil companies coming there has only some cases where the oil companies actually owned up to there mistakes and tried to fix what happened. The oil companies committing crimes also shows distributive justice in this case and they should be held for the cost of the victims suffering. They are destroying these people lives, these people have been there for many years before the oil companies have but they are just coming in and taking over their land and destroying it. The oil companies need to take action for what they are doing and own up to their mistake. Once again the best alternative is to not spill the brine and if we do we will take care of it. This shows that we are paying for the actions that we have committed if we do spill the brine onto the farmland. We own up to what we did and we will do the best that we can to respect the famers that have been there before us because they are to trying to make a living. The second alterative once again is not a good idea because this shows that we do not care about the people that were there before us and that we are just in it for the money, like all th e other oil companies that are there.
