【REVIEW】 calculations involving new technology or a new IT approach emerging IT project ROI, such as SOA most of the time will be an art, not just a science. SOA provides four basic benefits: reduced integration expenses, improve asset reuse, improve business flexibility and reduce business risk.
In the increasingly complex rules, the increasingly fierce global competition, rapid changes in the budget is relatively tight in today Internet world, the company (or government) need from their technology investments in the necessary results. No CEO is not willing at a fixed expected value of new technology investment. When people understand that a defined technology and its return on investment over time, after the calculation of the risk of an IT investment ROI (return on investment) will be a very straightforward process. However, a calculation involving new technology or emerging IT methodology IT project ROI, such as SOA most of the time will be an art, not just a science.
Return on SOA investments made more challenging factor is that this structure allows the company itself does not offer may be different from them in return for some specific characteristics. Ultimately, this structure is a company must do well before any return, and to the SOA implementation process ongoing investment. So, how can we calculate these projects to fruition before the SOA investment returns? What is a limited return on investment for the implementers of SOA brings the visible profit? On the other hand, the company should provide to the organization how to calculate that the visible expected profit return it? only understand the value of the SOA program, companies can calculate the return on investment for SOA. Even so, before the completion of the project, SOA in the real return on investment is unknown, because SOA is a fundamentally unpredictable business changes.
Reduce fixed costs
SOA provides four basic benefits: reduced integration expenses, improve asset reuse, improve business flexibility and reduce business risk. These four core benefits for the organization and part of the revenue at many levels, depending on the type of company will apply to business problems SOA. Preferred, but loose combination of methods to reduce complexity, thus reducing the synthesis and control the cost of distributed computing environment. Despite the standard interface, such as Web services, integration costs will reduce the number, the true value, SOA coarse Ke Li Zai Yu Yong, loose structure of Fuwuqudai a small fine granularity, Congerkeyi Bi-based API for more convenient synthesis of The scope for more comprehensive treatment.
Consolidated expenditure using SOA to reduce the return on investment calculation is quite straightforward. Company may in the SOA-based Web services in the investment equivalent of the traditional complex with a method of comparison among devices, and will directly license and configuration reduce the cost of maintaining a longer period and changes in the cost comparison. As we in the Understanding the Real Costs of Integration ZapFlash as described in detail in the company can achieve a simple loose from the tightly integrated structure to the integrated structure of the important and immediate return on investment. Ultimately, companies can phase out their more expensive integrated approach and avoid bear the traditional, and infrastructure stripping losses. Companies can use their existing EAI and ETL projects step by step implementation of the SOA, to provide direct cost savings for the long term, SOA can significantly reduce the complexity, the company can gradually replace their traditional Intermediate Technology.
Improve asset reuse
Despite the comprehensive expenditure reduction can determine an initial SOA project, only to SOA as a way to reduce this expenditure is very short-in. SOA in a consistent environment is feasible. In addition, when the company needs to present a new infrastructure use, an integrated model for the center will not provide return on investment. However, the reuse of existing services for companies looking to implement SOA to provide additional return on investment. As we all know, the company has continued to change for those projects that required construction of new equipment, the time and budget are very small. Lack of attention to the development of new equipment as part of the reasons is that these new applications require frequent and before production and not related to existing applications, which will lead to a new IT issues, which will result in new elements to be integrated, so that we have mentioned comprehensive exacerbates the problem. Clearly, the establishment of new applications not only need to reduce development costs, and over time to maintain invariance.
SOA is an important income users can create new business processes of service delivery and the present synthesis. In other words, re-use of services better than the application of comprehensive. Since they can create new services, and can be recycled, the company can be synthesized from the application of their return on investment. Therefore, the synthesis of SOA application development as a lever of the economy will be with the company to create and then reuse the number of services increases. This may make now for 70% of consolidated funds for new development. The company's assets in the implementation of this SOA reuse is not only simplify the gains brought by a comprehensive cost reduction and improved time to market from product to more sensitive room service, reducing the overall number of employees, and better able to external procurement or production, implementation and composition of offshore services. SOA-based assets of any re-use of return on the investment earnings must be all part of the SOA value proposition are taken into account.
Increase the commercial vitality
Reduce costs and increase the reuse of the SOA provides a clear ROI, compared to increased business activity is the most promising benefits SOA also the most difficult to quantify. Reuse based on integrated technology to simplify and increase the revenue for the center, business users also expect from the IT industry to obtain greater flexibility. Start with a simple necessary conditions for building and then a hit in months of the realization of a long cycle of IT "Development of wall", the business users want more direct control over their operations in order to be able to quickly change the market to change their business .
To calculate the required ROI business activity programs focus on business users direct control of the accuracy and business process management capabilities. Through service-oriented process, the company that they will all be divided into many parts of the business process to appoint to the different organizations, each organization (the charge) the actual operation of the business of direct, timely control. The resulting SOA investments from the business profit (return) was significantly improved business efficiency, while the company's business processes embedded in their suppliers or business partners, its operation went. Therefore, not only affects the profits of the underlying operation of the company, but also affect its upstream (industry). Increase in business activity might be considered to obtain the company's previous revenue sources can not get the results and offer different ways for the company for their suppliers or business partners in order to obtain significant new profit business opportunities. By the regional expansion of SOA to business users, ROI as a whole can be developed into commercial areas, rather than simply as part of the IT industry.
However, the calculation of the commercial viability of SOA ROI is extremely difficult, because traders will want to add IT resources are naturally unpredictable. After all, the vitality of the global point may involve unexpected changes. Therefore, restrictions on commercial activity in a specific ROI range is justifiable, for example, changes in product information under the rules, procedures or other business partners and supply chain roles, corresponding to modify the regular
Reduce business risk
In accordance with the rules of business activity to improve an essential program, because this rule is arbitrary and will change as time changes. Now, like Sarbanes Oxley, PATRIOT Act, and Base II and other rules implemented in a number of IT within the company already has changed. If you do not obey the rules, the company's economic situation and the freedom of managers will have serious negative effects. Many companies in the business operations is not transparent, so they had to rely on the decision making framework to enact smart to 控制 their risk, but they ignore the increasing transparency Xing's request, this transparency of the rules of what they needed to.
