Abstract Services are combined and then controlled through an orchestration engine for achieving a business process. These services can be internal to the organization or COTS, which raises the question of authenticating the quality of the services. The problem currently being faced by the SOA developers is the lack of a system that guarantees a third-party service. A service provider may provide claims about a service but those claims need to be validated. Even the service provider might not have an idea that his service has degraded over time due to increase in traffic, data or some other elements. Each consumer has his own expectations from the service and different criteria are set as standards for the acceptability of a service. This paper contains the research conducted on the impact of a third-party service on a composite service and a model has been proposed for the testing of these services. INTRODUCTION Web Services have formed an important part of the internet in the current I.T driven economy. The Web Service is an interface that describes a collection of operations that are remote accessible through standardized XML messaging [17]. These services provide functionality ranging from simple mathematical functions to more complex banking applications over the web. Different businesses have adopted the technology of web services and started providing services through the web to their customers. Businesses have been striving to provide the best possible service to their customers by introducing new innovations into their services. The latest innovations in the field of web services include the concept of service oriented architecture and composite services. Service Oriented Architecture provides the principles that mak... ... middle of paper ... ...s”, International Workshop on Systems Development in SOA Environments (SDSOA'07) 0-7695-2960-7/07 © 2007 IEEE Anton Michlmayr, Florian Rosenberg, Christian Platzer, Martin Treiber and Schahram Dustdar, “Towards Recovering the Broken SOA Triangle – A Software Engineering Perspective”, IW-SOSWE ’07, September 3, 2007, Dubrovnik, Croatia Copyright 2007 ACM ISBN 978-1-59593-723-0/07/09 Matthias Galster, Eva Bucherer, “A Taxonomy for Identifying and Specifying Non-functional Requirements in Service-oriented Development”, 2008 IEEE Congress on Services 2008 - Part I . 978-0-7695-3286-8/08 2008 IEEE.

...iary. We achieved that by requesting a SOC3 report from the third party and interpreting/learning about the boundaries of their system. We learned that the company maintained effective controls over its system, which included controls over the infrastructure, software, people, and procedures. Therefore, we concluded that the system works effectively and the information gathered through this third-party intermediary will be reliable.
QoS – Quality of Service - is the overall performance of a telephony or computer network, particularly the performance seen by the users of the network.
Few systems for example: an embedded system is safety critical when installed in a vehicle. Such systems are extremely expensive to change; others must change frequently in response to varying requirements (e.g. business systems). Systems which are very expensive to change need extensive in advance analysis to ensure

Basically, a Browser/Server (B/S) model is adopted in the system design where nearly all computing load is located on the server side, while the client side is only responsible for displaying. In this project, SOA is used to facilitate data communication and interactive operations for the reason that each web service is an independent unit in SOA. The general structure of the web-based UMS using SOA is described as follows (Figure 2). In Figure 2, the server side is composed of GIS web service providers, an image cache server, a web server and a firewall.
While some large firms are able to find a service provider to cover some of their outsourcing needs. Few firms have found a service provider that can take over entire functions. Some have found that finding a service provider capable of providing services required only at a non-cost-effective-rate. The lack of a competitive marketplace may adversely affect the cost savings.

It is commercial software that enables integration of transaction oriented data and process throughout an organization. It comprises of several modules which enables the cross-organization integration based on the transaction data and business process. It is not a distinct object but acts as an umbrella by covering the whole business process. It supports the entire organization at various levels by providing with information in a highly integrated manner.
The subject matter of this paper is the integration of single sign-on based web architecture in place of the current design that provides multiple sites for company employees. Currently, employees wishing to access company related information are required to access approximately eight different websites and maintain records for different user names and passwords for each site. This paper will outline the design specifics that will be necessary for full integration and user functionality of the new web-based portal.
The eTOM Business Process Framework serves as a model for categorizing all the business activities performed by the service provider. Each area of business activity is defined in form of process components which can be broken into different levels of detail. These process components can then be positioned within a model to show organizational, functional and other relationships. They can also be linked to process flows facilitating end-end modelling. The eTOM can be used as a blueprint for categorizing and standardizing the activities performed by the service provider.

Operating system design goals and requirements are divided into two groups. What are these two groups?
Today, cloud services are widely used by people around the world in purpose of business, government, and personal use. With cloud services, users use resources - could be storage, computional capability, or software- from cloud service provider mediated by Internet. Doing computational work with cloud services involves a number of computers to do the large-scale works, therefore it usually called by distributed system over Internet (reference, paper?). Cloud service also offers a large-scale service where users only pay for what they use (on-demand). Therefore, companies migrate to business-to-business cloud as they don’t have to spend money building intial cost for their computational business. For instance, instead of building their own storage, network, cooling, they could just “rent” resource from cloud provider for the lower cost. Besides money benefits, cloud resources also able to be shared by multiple...
A service firm performance is usually measured in terms of quality. Nevertheless, these performance measurements can also be measured in terms of time, flexibility and cost, and they can also be used by a manufacturing company. In order to analyze the measures, I will divide them to the three main parts of operations, input – process – output:
The company has multiple standalone computing solutions and applications which it acquired through the purchase of provider companies. These systems are not fully integrated and are not compatible. They do not share data in real time making communication, access, and interoperability difficult. The current system does not provide a well designed and unified solution for customers. The different provider companies that XYZCorp has acquired currently have their own customer relationship management (CRM) systems. Currently, it is not possible to have interconnectivity and functionality between providers and external sources, causing customers to be unable to take advantage of and fully benefit from the range of services the company has to offer. Also, web technologies are not being used to their potential and backend applications are not integrated. A customer web portal, which can help to integrate services such as buying, selling, delivery, payment and overall customer support, is non-existent and a deterrent to overall consumer satisfaction and business growth.
