Information Technology Advantages and Disadvantages

reading engineering science Advantages and DisadvantagesThe importance of Information engineering scienceThe importance of engineering comes from that Technology has an with child(p) impact on establish manpowert and the development of societies and economies. This impact rotter be observed in three yards.The first step is substitution, new name engineering substitutes for the old. For example, consumers start substituting their fixed skirt lines with mobile teleph unitarys. The chip step is the diffusion, when adopting the new applied science is widely across society beca hire it is law salute or better or more answerive than the previous engineering science. The final step is transformation when the new engineering ways start written reportings and emerging beca role the new technology is diff give wayoutd so widely in society. For example, the widespread adoption of the networking has led to interesting innovations in the communication patterns of individual s such(prenominal) as executives conducting transaction while waiting in airport lounges or traveling in trains.( DUTTA MIA , 2001)World Economic Forum.ICT offers more opportunities for economic development and plays really important role in international competitiveness, rapid economic change, and fatty capacity of improvements for developing countries. ICTs offer the developing countries umteen opportunities, as it has through in the positive world, when it created unprecedented possibilities for them. Studies deport emphasized that in that respect is depict of a strong linkage among GDP harvest-feast and ICT investing constituteing the importance of ICT investment for development. According to an OECD seek project, which was conducted in the yr 2002, in that location is an impact of ICT on the economy. In addition, in the GDP growth per capita, ICT investment accounted for amid 0.5% and 1.3% (Nodu, 2004).Also, Organizations read join ond their investment in br eeding technology IT for planning in enjoin to incr simplicity the skill of their task processes. Support encounter it awayment decision making and improve productivity. So IT bring forth important tool to attaining competitive advantage for the physical composition and improves employees productivity and efficiency (Kim lee(prenominal) Law, 2007)Besides, M each researches investigate the correspondingness betwixt IT investment and incr slackening the productivity and the performance in the companies one of these studies (sircar et al, 2000) which put in several strategy of rules success with the spending on the IT but others were failed. (Agarwal karahanna, 2000) argue in this end that IT investment depart be successful when IT utilized by the governance intended intaker in the way contribute to the dodging and the goals of the firms. in that locationof workr borrowing is the severalize for the successes of the IT investment (Darsono, 2005).Also, for mo re than two decades nurture technology has been the focal point for researcher in instruction establishment this is beca subroutine IT considers as the key to lead the organization for the good performance so many researches focus in the initial agreement for IT or continuous procedure of goods and services foe IT (Premkumar Bhattacherjee, 2005).The advantages and disadvantages from adopting development technology(brien maracas, 2008, management reading brass, edition 8, chapter 1, p55) the advantages (for strategy advantage).Information technology hires to certification the competitive strategy in helping the companies to reduce the costs of the order to give special offer for its products and operate and give better cargon ab off customers and suppliers and to develop unions among the company and the company with the environment around the company and incr backup man the virtue of its investment in IT resources.By development the cultivation technology the org anization or the companies ordain be able to develop the value of its business through out making the customer value the focus of its strategy which is to keep get behind of its customers p impactences to supply its products and services any conviction anywhere by using the internet or intranet and extranet(e-commerce websites).A lot of organizations/companies enforce reading technology and internet to reengineering its business process beca implement breeding technology can even off integration for the organization to work for the same goal of the organization and this improves the design of the work flows or the requirements of the job even the organization structures even improve the efficiency and the ensn beiveness.Information technology provides the communication and the information required for the managers in order to manage the different activities within the organization and the resources from the partners to get the advantage from the changes in the food market e nvironment.Information technology can support the organization competitive strategy by making the organization as the k without delayledge creating to make innovation by creating its process style or product and service for its work or learning organization by doing similar in what the other companies created by using the internet to get the k straightawayledge that it needs.The disadvantagesSome disadvantages of information technology includeUnemployment While information technology may have streamlined the business process it has too crated job redundancies, downsizing and outsourcing. This promoter that a lot of lower and middle take jobs have been do away with causing more people to become unemployed.Privacy though information technology may have made communication quicker, easier and more convenient, it has also bought along privacy issues. From cell phone signal interceptions to netmail hacking, people atomic number 18 now worried about their once snobby information becoming public knowledge.Lack of job security exertion experts believe that the internet has made job security a big issue as since technology keeps on changing with each day. This center that one has to be in a constant learning mode, if he or she wishes for their job to be secure.Dominant culture While information technology may have made the world a worldwide village, it has also contributed to one culture dominating some other weaker one. For example it is now argued that US influences how just about young teenagers all over the world now act, dress and behave. Languages too have become overshadowed, with English becoming the principal(a) mode of communication for business and e rattlingthing else (http//www.smallbusinessbible.org/advan_disadvan_informationtechnology.html 3/4/2009 510am). vex reviewBehavior markAccording to (Davis , 1989 Kiraz Ozdemir, 2006 Hwang Y. Yi, 2002 Phau Gan, 2000)The technology betrothal framework TAM consists of four briny component p arts as major determinants of technology credence these factors argon discernd facilitate of engagement, sensed riding habitfulness, the trademarkures toward the usage and the relative frequency of habituate of technology. That meat if people want to accept or jib any specific technology they should surpass utilisationrs believes that this technology will help them do their work better and this refer to sensed physical exercisefulness and extend their believes in that the system is alleviation of engross and the benefit is more than the drive from the excogitation for this technology. In another wards, If the utilizationrs embrace easy of riding habit from that technology and perceive proceeds from the technology for their work purposes .that means, there are Positive attitudes toward the technology usage n have a prescribed kindly intercourse with the demeanour objective to utilize the technology.Therefore, (Chang, 2004) was conducted The correctio n which purposed to search the validity of the annexe of Technology Acceptance Model (TAM) based on societal and facilitating as main factors to predict intranet/portal usage beca aim those factors are most overriding in the educational environment. The moot found that there was strong positive semblance among perceived re liberate, comprehend remainder of use and users attitudes towards the intranet. And the Attitude has strong affinity with the user aim to use. And the objective to behave had a strong congenator with the essential usage this conform the positive substantial likeness in TAM and its constructs are to predicting the user credence of the intranet/portal. take down there are relation between experience and comprehend avail and sensed rest of use. Even experience is a stronger predictor for comprehend alleviation of use and perceive value than age does.So, Technology Acceptance Model (TAM) which created by (Davis Bagozzi Warshaw, 1989 Davis et al., 1989) Studied some important factors bear upon in the use of the information technology. the TAM explained how the way goal to use the technology raiseed by one basic factor to cause the existing use for the new system, therefore the sort invention to use the technology is the merely or only determined related to developed use for the system, beside that the latest studies sustain that the behavior bearing to use the technology is the merely mediated factor. In another words, the TAM explains attitude factors affecting the behavior objective to use with putting the focus on the attitudes as a factor to use the technology (Kiraz Ozdemir, 2006).And in contrast that, the attitude not the only the factor who is affecting on the behavior intention to use but there are another factors can affect the behavior intention to use as in the con was conducted by (Gong Xu Yu, 2004) which aimed to identify additional determinants factors for the technology word sense in the educ ation sector. The get a line found that there are cipher and mediate satisfying assemble for perceive improvement on the behavior intention to use the system and this effect is strong on the behavior intention to use more than the effect on the attitudes and the attitude was formed by perceive usefulness. Beside, that perceived relievo of use has effect on perceived usefulness and the attitudes of the users but the effect on the attitudes was not earthshaking this collectible to the combination of the factors like organization, subjects and the technology or collect to the users have one month experience and they need to use the system easier and free of effort .and self-efficacy has strong ship effect on intention to use and perceived puff of use but on easement of use more effect than intention to behavior.Another reckon was conducted to swan that intention to behavior is determined the actual behavior by (Aversano, 2005) which purposed to explore why some people retract to use the mobile telephone in USA. The look at used the possible action of Ajzen to give exploration of adult male behavior to instinct a persons actions in behavior like social attitude and personality trait it considered as important to explain merciful behavior. And the meditate used TPB to confirm that intention to behavior is determined the actual behavior. And there are three factors predicting the function to behavior are attitude, inbred norms and perceived behavior control as same as TRA with focus in the important of the intention to behavior with the adoption for the technology. Even the speculate used the TAM2 which explains perceived usefulness in terms of cognitive and social influence processes.(Aversano, 2005) was conducted the charter which purposed to explore why some people refuse to use the mobile telephone in USA. The study used the theory of Ajzen to give exploration of human behavior to sense a persons actions in behavior like social attit ude and personality trait it considered as important to explain human behavior. And the study used TPB to confirm that intention to behavior is determined the actual behavior. And there are three factors predicting the Intention to behavior are attitude, prejudiced norms and perceived behavior control as same as TRA with focus in the important of the intention to behavior with the adoption for the technology. Even the study used the TAM2 which explains perceived usefulness in terms of cognitive and social influence processes.Moreover, in the latest studies, like the study was conducted by (Hwang Yi, 2002) in the inseparable motivation and computer self-efficacy research to Technology Acceptance Model in order to predict the use of web-based information systems. The study found that behavioral intention and self-efficacy have a significant effect on actual use. Even perceived usage and self-efficacy were significant determinants of ease of use. Even was found that self-efficacy w as a strong determinant for ease of use and actual use. The study support all the dealings were purposed in the technology acceptance model. Even the studies (Klloppiing McKiinneyy, 2004 Jones S. Hubona, 2005) support that relation.Also, the study was conducted by (Jones Hubona, 2005) which aimed to determine the effect of staff seniority, age, and education level on usage behavior. The study back up all TAM construction. Even Education level would directly affect actual usage behavior besides effect on perceived ease of use and perceived usefulness. But in contrast, the study was conducted by (Al Mutairi, 2007) which goaled to examine TAM pertinence in capital of Kuwait ministries. The study determination did not support the birth between the variables as were in TAM. In another ward, the study didnt find relation between ease of use and usefulness this in one hand and in the other hand there is no relation between ease of use and usefulness with actual usage. And the study mention that maybe because the differences in the national cultural, public organization context, dependent variables nature.Also, in the study was conducted by (Chismar Patton, 2002) which made among the physicians to examines their intention to adopt Internet-based health applications by using the pertinence of the (TAM2). The study found that the strong determinant for intention to use was perceived usefulness. Intention to use by physicians was explained by the make of usefulness and takings quality. And the relation between perceived usefulness and intention to use was significant, whereas image, subjective norm and perceived ease of use were not significant. And that due to that physicians have uplifted level of adaptability, cognitive capacity and intellectual, they comprehend faster than the universal people for new technologies. And they are willing to adopt information technology that has beneficial applications even if it not easy to use.Attitudes and BelievesAccordi ng to (Davis , 1989 Kiraz Ozdemir, 2006 Hwang Y. Yi, 2002 Phau Gan, 2000)The technology acceptance model TAM consists of four main factors as major determinants of technology acceptance these factors are perceived ease of use, Perceived usefulness, the attitudes toward the usage and the frequency of use of technology. That means if people want to accept or reject any specific technology they should set up their attitudes by increase users believes that this technology will help them do their work better and this refer to perceived usefulness and extend their believes in that the system is ease of use and the benefit is more than the effort from the use for this technology. In another wards, If the users perceive easy of use from that technology and perceive usefulness from the technology for their work purposes .that means, there are Positive attitudes toward the technology usage n have a positive relation with the behavior intention to use the technology.Therefore, in order to p ut spotlight in the important of mediating the attitudes for the relation between the beliefs and the actual usage for the technology (Chang, 2004) conducted The study which purposed to explore the validity of the extension of Technology Acceptance Model (TAM) based on social and facilitating as main factors to predict intranet/portal usage because those factors are most dominant in the educational environment. The found were that there was strong positive relation among Perceived usefulness, perceived ease of use and users attitudes towards the intranet. And the Attitude has strong relation with the user intention to use. And the intention to behave had a strong relation with the actual usage this conform the positive significant relation in TAM and its constructs are to predicting the user acceptance of the intranet/portal. Even there are relation between experience and perceived usefulness and perceived ease of use. Even experience is a stronger predictor for perceived ease of us e and perceived usefulness than age does.Also, the study was conducted by (algahtani, 2004) which aimed for more understanding of the acceptance for the technology in different cultures. The study found that there is strong support for the effect of the attitude in the behavior to use the computer and satisfaction. Even though this was back up in the study was conducted In Malaysia by (Mohd Syed-Mohamad Zaini, 2005) to identify the relation between information quality and the acceptance of doctors for Electronic Medical Record System (EMR) in one of Malaysian hospital. The study found that the information quality has significant consanguinity with perceived usefulness and perceived ease of use .even the perceived usefulness and perceived ease of use have significant relationship with attitude of using EMR system. Moreover, the user acceptance factor Information Quality has significant relationship with attitude of using EMR system through out easy of use and usefulness.The study c onducted by (Gong Xu Yu, 2004) which aimed to identify additional determinants for the technology acceptance in the education sector. The study found that there are direct and indirect significant effect for perceived usefulness on the behavior intention to use the system and this effect is strong on the behavior intention to use more than the effect on the attitudes and the attitude was formed by perceived usefulness. Beside, that perceived ease of use has effect on perceived usefulness and the attitudes of the users but the effect on the attitudes was not significant this due to the combination of the factors like organization, subjects and the technology or due to the users have one month experience and they need to use the system easier and free of effort .and self-efficacy has strong direct effect on intention to use and perceived ease of use but on ease of use more effect than intention to behavior.In contrast to The study conducted by (Gong Xu Yu, 2004), The study was conduct ed by (Yang, 2007) which Focus on the time in the affect of perceived usefulness and ease of use on the attitudes, which aimed to study the usage of the technology acceptance model for doing another examination of the relationships between students attitude toward the use of weather vaneCT and the determinants of the actual usage in light of social front line and sociability. the study found that The perceived usefulness and perceived ease of use was supported by self-efficacy, but more strong to the ease of use and twain(prenominal) perceived usefulness and ease of use support the attitude toward the actual usage this was in the first test for the relation and in the second test was found that the subjective norms was negative value to the social presence and the actual use but lower support for the actual use. The study focuses on the time which makes the personal effects of the variable in the attitude. Which means perceived usefulness directly changed by times after(prenomi nal) use the system.And the study was conducted by (Yalcinkaya B.A M.S, 2007) to investigate the acceptance for the police officer for the POLNET system in Turkish. The study found that Perceived ease of use has a positive effect on attitude and intentions to use the system. And the study considers that the variable ease of use considered the main factor effecting in the attitude toward behavior care to actual usage. This Result supported the depart for the last study by (Venkatesh Davis, 2000) which conformed that perceived ease of use is strongly related to the system usage. Beside that the study found that there is positive affect for Perceived ease of use on perceived usefulness of police Officers using the system. In another ward, those police officers preferred to use the system because its easy to use. And the same for Perceived usefulness has a positive effect on the attitude and has a strongly effect on Attitude and Intention to Use the information technology, the study mentioned that Turkish police officers using the system because they perceive the system is useful. Hence, perceived usefulness and perceived ease of use are very strong predictive factors on attitude and intention to use the system.From the receptive two studies, both studies (Yang, 2007 Yalcinkaya B.A M.S, 2007) confirm that perceived ease of use and perceived usefulness affect on the attitude which in the same time attitude affect on the behavior intention to use toward the actual use for the technology. Regardless the stronger affect on the attitude.The study conducted by(Ahn Ryu Han, 2007)which its goal to investigated the waggery effect ion on user acceptance of online retailing , tested factors of Web quality and the relationship between those factors and user acceptance behavior. The study found that there are significant between playfulness and attitude and behavior intention to use. Even there is significant and influences for service quality, perceived strengths of system and information on playfulness, usefulness, and perceived ease of use. Even there are significant for System quality influence on usefulness, ease of use and playfulness. Even Information quality had significant influenced on usefulness, ease of use and playfulness. Service quality had significant influence on playfulness, ease of use and usefulness. Besides that Playfulness considered an important factor affecting the attitude and intention to use online retailing users.In contrast, to the study conducted by (Kiraz Ozdemir , 2006) which target the utilisation of technology integration in the classroom focused on educational ideology, a factor not related to technology that also affects decisions in terms of educational applications. The study found that there is a direct effect of perceived usefulness on the actual use, and there is also a direct affect of perceived ease of use on attitudes. Besides, this study showed that attitudes towards the usage effected by perceived usefulness, and there is no significant effect of attitude towards usage and the actual use, this contrast the result in (TAM).Also, the study shows that there is no significant relationship between perceived ease of use and perceived usefulness. In another wards, there is a strong positive relationship between pre-service teachers perceived ease of use of educational technology and their attitudes toward use. The study mentioned that all of the ideologies were mentioned have effects on attitudes toward use. Moreover, educational anarchism, educational libertinism, and educational intellectualism have an effect on the perceived usefulness of technology. Both studies show that there is affect for perceived ease of use and usefulness on the attitude towards the behavior intention to use toward the use of the technology.Perceived ease of use and perceived usefulnessIt is important to understand that the perceived usefulness and the perceived ease of use of the technology are not forme d solely by the usefulness and ease of use of the technology. According to the study was conducted by (Park Brien Caine Rogers Fisk Ittersum Capar Parsons, 2006) which aimed to identify variables that can provide more understanding for technology acceptance. The study mentioned that there are many variables affecting the technology acceptance like technology characteristics, organization characteristics, subjective norm, User characteristics all interacted with the acceptance through out a positive effect on perceived usefulness.Beside that, the study was conducted by (Kishore Lee McLean, 2001) which used social cognitive theory (SCT), computer self-efficacy (CSE), technology acceptance model (TAM), the risk management, personal general innovativeness and specific computer self-efficacy to extend TAM. The study was mentioned that perceived usefulness and ease of use were granted as the main factors effecting in the actual usage.Also, the study was conducted by (goeke, 2006) which aimed to examine the effects of experience and expertise on the actual use for the data storage warehouse by using TAM. The study found that perceived usefulness and ease of use had significant effect on the usage for the technology and the usefulness stronger in the effect then ease of use. Even there is direct effect for the usefulness in the actual usage for the system. Also found there is direct effect for ease of use on perceived usefulness. And there is positive effect for the external variable on both perceived usefulness and ease of use.The result from (goeke, 2006) was supported in the study was conducted by (Brown, 2002) which aimed to examine perceived ease of use for the technology web-based in learning environment in developing country not developed country. And the finding was that the study confirms TAM relations that ease of use predicts the usefulness and the actual usage but usefulness doesnt predict the actual usage. besides, there are significant influences for self-efficacy and ease of finding and ease of understanding on perceived ease of use and ease of understanding more influences than ease of finding on perceived ease of use and the self-efficacy is the strongest influences on the ease of use but computer anxiety was the fewer influences.Inconsistent with former research (Bani-Ali Money, 2005) the effect of ease of use is lower than other proposed factors. A possible explanation is that users level of experience with new software may influence the relative importance of system ease of use. Despite, the study which contacted by (Hasan Ali, 2006) to distinguished between general, system-specific CSE and examines the effects of both levels of CSE on two key nurture outcomes reactions and learning performance. Reactions were examined with respect to perceived ease of use and perceived usefulness. The findings were that general CSE had significant effects on perceived ease of use and far-transfer learning. Even the study found that GCSE demonstrated a non-significant positive effect on perceived usefulness. On the other hand, SCSE exhibited a non-significant negative effect on perceived usefulness this because study were measured two weeks after training.Also, The Study was conducted by (Saeed Helm, 2008) which proposes that perceived usefulness affected by information quality and system integration which will then drive post adoption usage of the IS. The study findings support that system integration and information quality are significant predictors for usefulness, even usefulness positively and significantly relates to extended usage and exploratory usage. The Study mentioned that perceived usefulness affects the initial acceptance of IS, that means, there is a stronger relation between exploratory usage and usefulness.More over, the study was conducted by (Gyampah Salam, 2003) which aimed to examine ERP training and ERP project communication, will affect the TAM variables only through the psychological varia ble-shared beliefs in the perceived benefits of the ERP system. The study found that perceived usefulness is the important factor affecting in the beliefs to make positive attitudes towards the system. Even that the study supports that perceived ease of use not affect attitude towards using particular system. This supports others studies that show that perceived ease of use does not have a significant on attitude in the usage for the system. Even was found that training has important and significant positive influences on the shared beliefs in the benefits of the system and shared beliefs influence both the perceived usefulness and perceived ease of use of the system through out affect attitude, which in turn affects intention to behavior. Study confirms that communication with effective training affect the join TAM variables. And the training on the system has significant affect on perceived ease of use.Besides that, the study was conducted by (Yi Hwang, 2003) in the intrinsic mot ivation and computer self-efficacy research to Technology Acceptance Model in order to predict the use of web-based information systems. It found that behavioral intention and self-efficacy have a significant effect on actual use. Even perceived enjoyment and self-efficacy were significant determinants of ease of use. Even was found that self-efficacy was a strong determinant for ease of use and actual use. The study supported all the relations were purposed in the technology acceptance model. Even the studies (Klloppiing McKiinneyy, 2004 Jones S. Hubona, 2005) support that too.Perceived usefulness and playfulness considered as importance from the inexperienced e-commerce shoppers prospective. That means sites playfulness is essential to perceptions of usefulness, while for more experienced e-commerce shoppers, the perceived usefulness of the site can be evident independent of its playfulness, that was proved in the study was conducted by (Klopping McKinney, 2006) which conducted to examines the role of experience on consumers intentions to shop online. The study found that experience has direct and indirect effects on intention to use e-commerce, and there are moderating effects on perceived usefulness, playfulness, and self efficacy to intention to use e-commerce. Besides, there is a significant difference in the relationship of playfulness on perceived usefulness between inexperienced e-commerce shoppers and experienced e-commerce shoppers.Even, in the study was conducted by(T-Pikkarainen K-Pikkarainen Karjaluoto Pahnila ,2004) which aimed to increase the understanding of the factors that influence online banking acceptance from the technology acceptance model (TAM) prospective and to study consumer acceptance of online banking in Finland . it found that Perceived usefulness, Perceived ease of use, perceived enjoyment, information on online banking, and security and privacy have an impact on the acceptance of online banking and Perceived usefulness an d the amount of information on online banking the most factors influence the use of online banking services. And found that Perceived usefulness was more than Perceived ease of use effective in explaining technology acceptance.There is significant in the relation between perceived usefulness and perceived ease of use for accepting the technology, that was supported by (Almutairi, 2007) which aim to test the applicability of the technology acceptance model (TAM) in Kuwaiti ministries in order to understand the information technology in the government utilities, that also was supported in The study conducted by (Singletary Akbulut Houston, 2002) which purposed to identify factors that effect the acceptance of high school students for software application when the initial use of the application is mandatory. The finding was that there are positive relationships between perceived usefulness, ease of use and innovative usage behavior and there is a positive relationship between perceive d usefulness and perceived ease of use.The study was conducted by (Venkatesh Morris, 2000) which aimed to investigated gender differences in the context of individual adoption and the study conformed technology usage in the workplace by using technology acceptance model. The study found that There is a difference between women and men in that men perceived usefulness to a greater longitudinal than women in using a new technology. And perceived ease of use was more important to women compared with men after basic training and by the time with more experience in using the system that make not significant and not affect on the intention to use the system. But for women ease of use consider the important to affect the intention to use the system.Individual differencesIndividual acceptance for IT becomes an issue for resea
