End User Computing

How much end-user computing is too much? Should end users develop systems? This case looks at a study of end user computing within the engineering organizations of an electric utility undergoing deregulation. The case was initiated when management perceived that too much engineering time was spent doing IS functions. The case found that there was significant effort being expended on system development, support, and ad hoc use. Reviews of a few key systems illustrate quality problems found with the end-user developed systems. Several issues were identified affecting system development including use of programming standards, documentation, infrastructure integration, and system support. Additionally, the issues of obsolescence, security, and procurement are discussed.

What happens when end users do not respect the IS organization and have high computer self-efficacy? Will the end users develop usable systems and will they ignore IS? This chapter reports on a study of end-user computing within the engineering organizations of an electric utility undergoing deregulation. The study was initiated when management perceived that too much engineering time was spent doing IS functions. The study found that there was significant effort being expended on system development, support, and ad hoc use. Several issues were identified affecting system development, use of programming standards, documentation, infrastructure integration, and system support.

End User Computing

Although gender differences in a technological world are receiving significant research attention, much of the research and practice has aimed at how society and education can impact the successes and retention of female computer science professionals. The possibility of gender issues within software, however, has received almost no attention, nor has the population of female end users. However, there is relevant foundational research suggesting that gender-related factors within a software environment that supports end-user computing may have a strong impact on how effective male and female end users can be in that environment. Thus, in this article, we summarize theory-establishing results from other domains that point toward the formation of grounded hypotheses for studying gender differences in end-user computing. There has been much background research relevant to human issues of end-user computing, which we define here as problem-solving using computer software, also termed end-user programming in some of the literature (e.g., Blackwell, 2002; Green & Petre, 1996; Nardi, 1993). (See the glossary for definitions of these and related terms.) Despite this, few researchers have considered potential gender HCI issues and gender differences that may need to be accounted for in designing end-user computing environments. The most notable exception is Czerwinski’s pioneering research on the support of both genders in navigating through 3-D environments (Czerwinski, Tan, & Robertson, 2002; Tan, Czerwinski, & Robertson, 2003). Although individual differences, such as experience, cognitive style, and spatial ability, are likely to vary more than differences between gender groups, evidence from Czerwinski’s work as well as work in other domains, such as psychology and marketing, has found gender differences relevant to computer usage. In fact, some research has shown that some software is (unintentionally) designed for males (Huff, 2002). One reason gender HCI issues in end-user computing are important is that ignorance of gender issues has already proven to be dangerous: today’s low percentage of computer science females (Camp, 1997) has been directly attributed to the past unawareness of gender issues in computer science education and in the workforce. There is a risk that if gender HCI issues in end-user computing environments are ignored, a similar phenomenon could occur with female end users.

User Productivity

End-user computing (EUC) has led to increased end-user productivity and satisfaction. In order to reduce the risks inherent to EUC, organizations should better manage EUC. As a first step different groups of end-users must be identified. Existing classification schemes have weaknesses and fail to capture the different roles contemporary end users play. Cotterman and Kumar (1989) proposed a user cube based on the three main dimensions of EUC -development, operation, and control. Even though this is rational approach to end user classification, it has been largely ignored by researchers. This may be due to the lack of an instrument to implement the cube. Hence, in this paper, a 10-item instrument is presented and data collected from 292 end users show that the instrument has strong construct validity. Practitioners can find this instrument very useful in determining the characteristics of EUC in their firms which in turn would be beneficial to devise strategies for EUC management.

End-user satisfaction has always been an important component of Information Systems (IS) success. This is also true for online applications, including online shopping systems, where in addition to being a customer, the shoppers play the role of end-users. Shoppers may not come back to or make a purchase on a Web site if they have an unsatisfactory experience. In this research, we focus on this aspect of online shopping by examining shoppers’ experiences as end-users.

Knowledge is receiving recognition as a strategic force in organizations. Correspondingly, one form of knowledge capture and maintenance organizations are tempted to use is expert system design by end users. The chapter discusses difficulties associated with end-user development, both in terms of design quality and knowledge content. An analysis of 25 expert systems written by non-professional developers reveals significant quality and size limitations that indicate limited feasibility of end-user expert system development. Furthermore, the lack of design quality may not be easily compensated for by a “knowledge advantage” of the end users, as end users may have a performance advantage in using their knowledge, but not in “knowing” it. The chapter then offers suggestions for alternate forms of end-user oriented expert system development that considers end-user limitations and takes advantage of recent developments in information technology.

ABSTRACT The oil pollution prevention program of the U.S. Environmental Protection Agency (EPA) addresses a large regulated community—the owners and operators of several hundred thousand nontransportation-related facilities. Regulated oil facilities generally are thought of as refineries, terminals, production field tanks, fuel oil dealers, or gasoline service stations. Some studies of the nationwide petroleum storage capacity do not even consider tanks owned by petroleum consumers, while others recognize that end users constitute a significant part of the nation's oil storage. The storage capacity of fixed petroleum tankage in the tertiary segment (agricultural, commercial, electric utility, industrial, military/government, residential, and transportation sectors) is estimated to comprise more than 20 % of the total U.S. storage capacity. EPA estimates that more than one-half of the facilities required to prepare Spill Prevention Control and Countermeasure (SPCC) plans are such end users. The focus of oil pollution prevention, of course, is preventing spills. Several years ago, an American Petroleum Institute report on aboveground storage tank incidents stated that more than 25% of large petroleum releases in the United States were from tanks controlled by companies outside the petroleum industry. Recent data on large spills (10,000 gallons or more) show similar patterns. Of course, most nontransportation-related spills are from storage tanks or facilities in the petroleum industry (production wells, refineries, terminals, tank farms, and fuel oil dealers). More than 40%, however, are from electric utilities, manufacturing plants, military bases, airports, railroad yards, and other end user facilities. Smaller spills come from a variety of facility types. It is important for EPA and other groups to recognize the end user community and the threat of spills from end user facilities, and to begin to work with the owners and operators of end user facilities to educate them about EPA's oil pollution prevention regulation.

With an advent of gaining popularity in cloud computing, there is a huge demand in ad-hoc services by the end users. These ad-hoc services cannot fully be provided by a service provider; hence Cloud mashup is a solution for this requirement. Cloud mashup is technology where end users can integrate different services of cloud service providers and create their own customized ad-hoc services. This paper proposes an efficient enterprise cloud mashup framework which supports dynamic composition of services to create a new service to the end users. The proposed framework is composed of an adapter, widgets, widget library and a mashup constructor module. Even a non technical end user can easily generate their own customized service on a cloud platform. Experiments reveal that the proposed framework is an efficient enterprise with cloud mashup service integration framework.

End User Computing

Contemporary end users are more knowledgeable about computing technologies than the end users of the early ’80s. However, many researchers still use the end user classification scheme proposed by Rockart and Flannery (1983) more than two decades ago. This scheme is inadequate to classify contemporary end users since it is based mainly on their knowledge and ignores other crucial dimensions such as control. Cotterman and Kumar (1989) proposed a user cube to classify end users based on the development, operation, and control dimensions of end user computing (EUC). Using this cube, users can be classified into eight distinct groups. In this research, a 10-item instrument is proposed to operationalize the user cube. Such an instrument would help managers to identify the status of EUC in their firms and to take appropriate action. Based on the data collected from 292 end users, the instrument was tested for construct, convergent, and discriminant validities. Researchers can use this instrument to study the interaction between constructs such as development and control with end user computing satisfaction (EUCS).
