Evaluation of SOA in Manufacturing
Based on an analysis of the secondary research used for the completion of this paper, approximately 40% of all companies today with SOA frameworks which serve as the foundation of their strategies are actively tracking the ROI of these activities according to Gaughan, Gannon and Swanton (2006). The development of transaction-based APIs is necessary for many manufacturers, as their order management systems are significantly different than their trading partners, distribution channel partners, service and support third-party organizations as well. This aspect of SOA adoption in manufacturing is comparable to the development of transaction-based private trading exchanges (PTX), where transactions were the only element everyone could agree on (AMR Research 2001). The use of these APIs to enable transactions has however become much more pervasive and agile compared to their previous-era PTX counterparts. Transaction-based APIs require the use of XML to ensure pervasive synchronization of all systems using the communication protocol according to Alonso, Kuno, Casati, and Machiraju, (2004). Abrams and Andrews (2005) also make the point that ERP system integration is increasingly be completed to ensure real-time transaction data as a result of XML's growth and the use of transaction-based APIs. The highly transaction-oriented approach to integration is a catalyst for the adoption of Web Services throughout manufacturing today, as the majority has multiple sourcing, production and fulfillment locations, and further increasing adoption of SOA frameworks throughout manufacturing companies. SOA's reliance on XML, EDA, and Web Services in conjunction with composite applications is what makes this strategy differentiated and agile, according to Andrews (2005).
From the research completed within this paper, there is evidence on the greater the maturity of the SOA framework within a manufacturer the more precisely Web Services align to customer-facing strategies. In the case of the objective of Increasing Revenues for example, it's clear that to attain the metrics defined in Figure 3 there must be tight process integration across, Sales, Engineering, Manufacturing, Pricing, Service and Management. This is also supported by the extensive work of Austvold, Carrillo, Preslan (2003).

Based on the research completed to define the KPis and their results in Figure 3 it was found that a manufacturer's ability to capture and re-define processes is just as important as the build-out of an SOA architecture including its many components. The results of Forrester's Business Technographics Survey (2005) also support this assertion. For those manufacturers that has started measuring the financial impact of their SOA strategies, the role of business process re-engineering in conjunction with EDA and the selective use of Web Services has made this task more aligned with business objectives, supported by research...
This specific research finding is supported by research from the Aberdeen Group, AMR Research, Gartner Group and others who have quantified the gains of SOA integration in the context of order capture. These research and advisory firms report that the net effect has been a drop of order cycle times from, worst case 33 hours, to less than 1 hour, also supported by research by Baghdadi (2005). In aggregate the order cycle times dropped significantly as a result of the combined effects of integration, creating an EDA-based structure for exception handling (which is the part of any process that takes the majority of time to complete manually in an order capture and order management system), and the development of business process exception handling using BPEL-based applications. It is also a significant finding from this research that integrating the quote workflows to reflect both Available-to-Promise (ATP) and Capable-to-Promise (CTP) on each customers' quote and order minimizes follow-on order inquiries while increasing the likelihood of a customer ordering again. Giving supply chain visibility to customers alleviates uncertainty while increasing trust and re-purchase, especially when the orders, however complex, are delivered on time (Manes 2003), (Columbus 2003).
Manufacturers are embracing SOA architectures and strategies to revolutionize and make more efficient the most complex processes in fulfilling customer requirements. Globalization, increasing pressure on pricing, and the need for increasing the speed of new product introductions are all macroeconomic factors that are forcing manufacturers to embrace SOA frameworks to unify, synchronize and ultimately strengthen their ability to attract, sell, serve and retain customers. From the research completed for this paper, a significant finding emerges that the majority of manufacturers are moving to SOA frameworks to streamline their customer-facing processes first. The quote-to-order process has been critically analyzed in this paper to illustrate the quantifiable gains manufacturers are making to one of their most complex customer-facing processes. From this analysis another key finding emerged from the research, and that was that the greater the complexity of customer-facing processes the greater the need for process and system integration, the higher the Return on Investment (ROI) as a result.
From this research it was also ascertained that the majority of manufacturing companies, nearly all of which have a highly-oriented metric-driven culture already, are measuring the performance gains to the process level when an SOA framework is introduced to support sell-side processes. A key conclusion is the evolving trend within manufacturers of measuring the impact of their SOA strategies has been an increasing focus on the Key Performance Indicators (KPIs) that signal financial performance increases as a result of greater collaboration and integration internally. Specifically the role of DSO (Days Sales Outstanding) as a measure of customer satisfaction as a result of tighter SOA integration is critical, as are many measures specific to the quote-to-order processes manufacturers are targeting with EDA and Web Service components of their SOA architectures and strategies.

In addition to the empirical evidence collected from secondary research illustrating SOA frameworks' performance over time, this study illustrates how pervasive the use of BPEL-based applications are becoming to re-align critical, revenue generating processes throughout manufacturing companies. The emergence of XML as the integration standard between BPEL-based applications, Web Services, analytics applications, and business strategies is clearly illustrated throughout the examples shown in this paper as well. Underscoring the convergence of business process re-engineering, Web Services, XML and the analytics applications used to measure performance is the redefinition of the role of the Chief Information Officer (CIO) as well. While the scope of this paper has specifically been on the adoption of SOA frameworks into manufacturing, during the research the trend of CIOs becoming more responsible for process redefinition over simply maintaining Information Technologies' (it) assets in a company. The need for greater research into the transforming role of the CIO as business process owner and enabler of strategic change through the use of SOA frameworks is an…
The vision Oracle has is one of unifying all of their enterprise applications into their Fusion architecture and creating a single unifying Service oriented Architecture (SOA) was first announced in 2006 (Krill, 13). Since that time Oracle has continually strived to create an SOA in Fusion that would appeal to its corporate customers. The proposed Fusion SOA platform has been designed to be robust and scalable enough to encompass enterprise-level

A book entitled "Surviving Security: How to Integrate People, Process, and Technology" explains that the rapid expansion networking and networking technologies necessitates greater security needs. The author asserts that parts of the network such as routers, switches and even network printers are vulnerable (Andress). The article further explains that the router or switch contained
Furuholt, (2006) argues that lack of management engagement to the acceptance of information systems has been a barrier to the implementation of information systems. The issues are even common with organizations in the developing countries where management does not give enough priority to the information systems implementation. Importantly, implementation of information systems requires management support since management will need to approve fund that would be used for IS implementation.
It is possible to avoid becoming a victim of such crimes through some basic precautionary methods. Firstly, it is essential to store or discard personal information in a careful manner. This means personal documents should not be left lying around or shared through internet. All personal information should be stored in a secure place. All sorts of old receipts, expired cards, bank statements and checks should be disposed of
Information System MIS stands for "Management Information System." It is one of the computer-based tools to manage organizational operations efficiently. It consists of software that managers' use in making decision, for data storage, in project management applications, for records and procedures for making customers relations etc. Nowadays most of the organizations have separate MIS department which is basically responsible for computer systems. MIS is also called "Information System" or "Information Technology."
