An exploratory study into factors of service quality for application service providers

An examination of the services offered by application service providers (ASPs) indicates that their current service quality needs to be improved to satisfy current and future clients. This study attempted to fulfill this need by identifying the dimensions of service quality for the ASP industry through both qualitative and quantitative approaches. As a result, seven dimensions were identified (features, availability, reliability, assurance, empathy, conformance, and security). In addition, an initial checklist was developed to help ASPs assess and diagnose their service quality performance. Some insights and implications to the ASP practitioners were also discussed.     

Myths about outsourcing to application service providers

Which applications are organizations outsourcing to ASPs? What did they hope to gain? And what are the critical success factors for organizations using ASPs? To assess these issues we cosponsored a study to assess organizational attitudes and adoption metrics for ASPs. Our survey garnered 256 usable responses from businesses regarding their use of ASPs. The study indicated that a significant number of respondents believed ASPs offer a fast-track way of implementing IT projects. However, 80 percent also favored internal implementation for core IT projects, which suggests that other factors still present a substantial barrier to ASP adoption. Nevertheless, companies are outsourcing some core applications - such as supply chain management and e-commerce - and several non-core applications. This outsourcing implies that companies perceive a significant benefit to ASP adoption. The message for users is unambiguous: to succeed, understand how Internet outsourcing works for your company, benchmark against successful ASP adopters, and establish a common criterion for evaluating an ASP     

Price and capacity competition of application services duopoly

In this paper, we study the price and capacity competition of two application service providers (ASPs). The customers realize an intrinsic time-independent value from transactions processed by the ASP. The cost to the customers includes both the price charged by the ASP and the delay cost due to turnaround time of the ASP service system. Customers will choose to join the ASP who delivers a higher net value of the service. This paper examines the competition between two ASPs and the impact of customers' delay cost on ASP's pricing and capacity decisions. We find that the ASP with higher capacity will charge a higher price and enjoy a larger market share and, surprisingly, that customers' delay cost has no direct impact on the arrival rates to the ASPs but affects the ASPs' pricing decisions. The ASPs will charge a higher price premium to capitalize customers' higher delay cost. For the long-run problem, we find that in the presence of higher customer's delay cost, both ASPs' optimal profits suffer, in contrast to the short-run problem where a higher customer's delay cost leads to a higher profitability for both ASPs.     

Resource provisioning for cloud applications: a 3-D,provident and flexible approach

The scalability feature of cloud computing attracts application service providers (ASPs) to use cloud application hosting. In cloud environments, resources can be dynamically provisioned on demand for ASPs. Autonomic resource provisioning for the purpose of preventing resources over-provisioning or under-provisioning is a widely investigated topic in cloud environments. There has been proposed a lot of resource-aware and/or service-level agreement (SLA)-aware solutions to handle this problem. However, intelligence solutions such as exploring the hidden knowledge on the Web users’ behavior are more effective in cost efficiency. Most importantly, with considering cloud service diversity, solutions should be flexible and customizable to fulfill ASPs’ requirements. Therefore, lack of a flexible resource provisioning mechanism is strongly felt. In this paper, we proposed an autonomic resource provisioning mechanism with resource-aware, SLA-aware, and user behavior-aware features, which is called three-dimensional mechanism. The proposed mechanism used radial basis function neural network in order to provide providence and flexibility features. The experimental results showed that the proposed mechanism reduces the cost while guarantees the quality of service.     

“When Do You ASP?” The Software Life Cycle Control Model

Application Service Providers (ASPs) now offer a new alternative for the acquisition and operation of application software, enabling companies to rent or lease applications that are delivered via the Internet. In determining the appropriateness of this strategy, companies must tradeoff the cost and time advantages of this approach with its risks. This paper introduces a Software Life Cycle Control Model that describes the dimensions of control over software features and operations associated with various software acquisition strategies, including internal development and operation, purchasing packaged applications, outsourcing, and ASPs. Transaction cost economics (TCE) is used to identify the key costs and risks that must be considered in the software acquisition decision. We propose when ASPs may be appropriate for companies with existing IT infrastructure and companies lacking infrastructure to develop and operate new applications.     

Application Service Providers: Will They Succeed?

This article examines the likelihood of success for application service providers (ASP) drawing from the outsourcing literature, interviews with ASPs in the USA, and the experience of Bennett who has held leadership roles in ASP and ERP in South East Asia. This article proposes that application service providers (ASP) rent packaged software, predominantly over the Internet. It shows why organizations might employ the ASP model to manage their enterprise resource planning systems. Using a framework adapted from Lacity and Hirschheim, it demonstrates that the financial, business, technical and political reasons why organizations evaluate outsourcing can be applied to ASP model. While ASPs generally target the mid-market, large enterprises are also using ASPs to introduce new ERP modules. Potential users of ASP should regard the risks of outsourcing prior to entering into business arrangements. This examination concludes that there are strong financial and technical reasons for adopting the ASP model and therefore it has potential to succeed.     

A Framework for Certification and Audit of Application Service Provider—ASP

Application service provider (ASP), network-based application rental service provider of information system (IS), has appeared as a new business style in information technology (IT) market. However, there are two main differences between the ASP model and traditional IS model. First, the relationship between ASPs and customers in ASP model is more temporary than in traditional IS model. Second, information resources of ASP's customers are located at the public network and data center. In these reasons, it is important that third parties need to certify and audit an ASP for successful implementation of the ASP model. This paper investigates characteristics of the ASP model and designs the framework for certification and audit of ASP. It is examined how the framework can remove potential threats and risks of the ASP model, and how the framework can be compared with traditional approaches.     

Exploring the supply-side of IT outsourcing: evaluating the emerging role of application service providers

The paper explores the supply-side of IT outsourcing by focusing upon the emerging role of application service providers (ASPs). It traces the transition from first wave IT outsourcing in the 1960s, to business-centric outsourcing in the 1980s and 90s to application outsourcing in the 21st century. Drawing from empirical research on a taxonomy of ASPs, the paper explores how application outsourcing is currently changing the nature of the outsourcing contract and relationship between client and supplier. This will have significant implications for traditional outsourcing and ERP vendors in the software and computing services industry, in addition to presenting new opportunities to SMEs with little history or experience of outsourcing.     

Asps: Do They Work?

Application service providers (ASPs) offer and manage outsourcing application services to many organizations via the Internet. Organizations outsource applications to ASPs to reduce upgrade and maintenance costs and to focus their efforts on core competencies. To that end, it is essential for CIOs and senior IT executives to understand the dynamics of the ASP market, services provided, and outsourcing trends within their particular industries. This study identifies the critical success factors (CSFs) for ASPs to sustain the fierce competition in the outsourcing market. the CSFs include delivery of applications, efficiency in responding to demands, management of resources, assurance of 24/7 access, meeting IT needs, and economic distribution of applications. Moreover, the study highlights issues of concern involved in outsourcing internal applications via the Internet, such as security, reliability, quality of service, employees' concerns, and existing infrastructure, and provides managers with an action plan to address these concerns.
