Web Service Implementation Essay Example for Free

Web Service Implementation examineChristiansen, S. (2002) once described web function as a potential political intrusion (p. 15). When we find what does this sentence mean and when we add the fact that web service are hot -by their nature- and not short to make them workable in practice like Siddhartha, P. (2002, p. 587) mentioned then we could be able to imagine nigh of the potential hurdle race that need to be all overcome to boffoly implement web services. Web services by their nature- belongs to IT projects category.Thats why it is important to realize the reality of IT projects. A 41% of IT projects failed to deliver the judge value and more than ? of IT projects were canceled (Needmuchwala, A. , 2008, p. 3) not to mention that only 11% of organizations consider technology as a strategic weapon (p. 3). Despite the fact that web services do not require gamy costs to be implemented like early(a) IT systems or solutions (ERP systems for example), the way to impleme nt web services isnt a bed of roses.And if we add those information mentioned above- to the fact that only 20% of companies gained significant hold with web services technologies (Altova, 2008), the picture will be clearer that there are some murder hurdles to be overcome such as the technological, organizational and cultural obstacles that stand in the way of capital punishment (Saugatuck, 2007, p. 3) prototypal of all, implementation is only a phase in managing IT solutions (web services in this case).And if the strategic supplying phase was successful and was done collaboratively by both top business management and IT department, taking into condition all possible hurdles or challenges, the implementation phase will be easier than with a reeking plan. However, despite the advances made in web services standards, achieving the seamless interoperability among heterogeneous platforms for the participating entities which is required for successful implementation of web service s- could be tricky as Siddhartha, P. (2002) mentioned (p. 587)What softens the situation is the fact -mentioned by Aponovich, D. (2002)- that none of these hurdles is insurmountable, each one of them could cause (1) potential delays to implementation or (2) adding barriers in the way to get maximal business value of web services (or return on a web services investment). Also, (Valentine, L, 2004) mentioned the fact that lack of standards in such technology wont be a deal surf maybe- because the extra coding process required for this standardization wont be too dramatic. The quin hurdles mentioned by Aponovich, D.(2002) was (1) lack of experience in architecting web services, (2) difficulties in managing the organizational culture change, or the ever-present hurdle, resistance to change as Provost, D. (2004, p. 19) mentioned- (3) lack of standards, (4) lack of perceived business cases, and (5) difficulties in managing relationships with other organizations There are numerous examp les for companies (or sites) that overcome these hurdles and successfully implemented web services with a real business value or return on investments (ROI). Amazon (http//www. amazon. com/) and eBay (http//www. ebay.com/) are two examples for those sites. In Amazons case, partners needed better data access but the process of collaboration was high-ticket(prenominal) and brittle (Dumbill, E. , 2003) thats why Amazon decided to provide web services. Certain issues were taken into context right from the planning phase thats why Amazon succeeded in referenceing these issues and finding the appropriate solutions. First of all, Amazon aligned the web services with their business strategy and decided to pursued revenue ground on the successful relationship with Amazons associates and seller (Dumbill, E. , 2003).Secondly, to guarantee success, the license was important to guard Amazons business model (Dumbill, E. , 2003). The third issue was concerning protocols Amazon provided both S OAP and XML over HTTP (REST) and let developers decide between them (Dumbill, E. , 2003). The fourth issue was to create a software platform and they address this by borrowing best practices (Dumbill, E. , 2003). The final issue was to successfully provide support for developers by information a combination of some tools such as discussion board, weekly chat, regular newsletter, software development kit, and online FAQ (Dumbill, E. , 2003).The most important is that Amazon provided openness with developers to foster creativity and focused on effectiveness by ensuring data freshness and preventing excessive server load (Dumbill, E. , 2003). Finally, it is obvious that the main factor, that leads to a successful implementation for web services, is the the full participation and engagement of the business (Jahnke, A. , 2004). Or in another word, to have warming the whole business into what Brynjolfsson, E. (2003) called the digital organization.And this digital organization includes (1) automation of tasks, (2) skilled labor, (3) decentralization of conclusiveness making, (4) improving the information flow across the organization, (5) adopting performance-based incentives programs, (6) more emphasis on the effectiveness of training and recruiting, and having employee and guest satisfactionReferencesAltova.
