Vol. 11, No. 2 Copyright ©1998, Idea Group Publishing. A Conceptual Development of Process and Outcome User Satisfaction JONATHAN B. WOODROOF Middle Tennessee State University, USA GEORGE M. KASPER Virginia Commonwealth University, USA Integrating three prominent organizational behavior theories of motivation (equity, expectancy, and needs) with concepts of information systems success, this paper develops a broad conceptual foundation from which to view and understand user satisfaction in information systems. This integration attempts to clarify many of the diverse dimensions of user satisfaction and examines the notions of process and outcome satisfaction and dissatisfaction in information systems. Much research has been done on the relationship between the success of an information system and the satisfaction of the people who use them. Yet many studies report inconsistent or contradictory results. Despite these inconclusive findings, the relationship between user satisfaction (US) and information systems (IS) success has great appeal. Historically, US research has been plagued by many problems. Directly measuring the success of an IS has been found to be impractical and perhaps impossible (Galletta & Lederer, 1989). Therefore, surrogates are used. The linkage between the operationalizations of US and the IS success construct has been tenuous at best. Methodological problems, such as weak construct validity, have also contributed to the lack of progress and the mixed results on US (Jarvenpaa, Dickson, & DeSantis, 1985; Zmud, Byrd, Sampson, Lenz, & Reardon, 1993). Perhaps the most compelling problem, however, is the lack of conceptual development (Jarvenpaa et al., 1985; Kim, 1989; Straub, 1989; Melone, 1990; Zmud et al., 1993). While the US construct has often been used to evaluate system effectiveness, there is no clearly articulated theory relating US to IS success (Klenke, 1992; Melone, 1990; Yaverbaum & Nosek, 1992). The purpose of this paper is to develop a more comprehensive model of US. The proposed model of US integrates three prominent organizational behavior theories (equity, expectancy, and needs) with the concepts of IS success. In addition to suggesting a theoretical foundation for US, this integration identifies the notions of process and outcome as critical to assessing IS satisfaction and dissatisfaction. The paper begins with a discussion of the various definitions of user satisfaction that have been used in IS research. Next, a model of US that synthesizes organizational behavior theories and the concepts of IS success is proposed. By integrating the organizational behavior theories of equity, expectancy, and needs with the concepts of IS success, a broad, theory-based foundation for US in IS is developed. The conclusions are then presented and implications of the model for US research are discussed. Manuscript originally submitted January 26, 1997; Accepted April 11, 1997 for publication. Spring • 1998 Information Resources Management Journal 37 The US Construct US has been defined as a learned disposition toward the objects of an IS (Lucas, 1973), a set of beliefs about the relative value of an IS (Swanson, 1974), “the sum of one’s positive and negative reactions to a set of factors” (Bailey & Pearson, 1983, p. 531), and “the extent to which users believe the information system available to them meets their information requirements” (Ives, Baroudi, & Olsen, 1983, p. 785). Other definitions include terms like “felt need,” “system acceptance,” “perceived usefulness,” “MIS appreciation,” “feelings about a system,” and “system friendliness” (Melone, 1990). There is currently no agreement on a definition for US and many of the current definitions of US are conceptually inadequate. According to Melone (1990, p. 80), This lack of agreement on the conceptual definition of the user-satisfaction construct has lead to a situation in which there are many operationalizations and an equal number of conceptual definitions, for the most part lacking theoretical foundation. There is also no consensus on how US should be measured. A plethora of instruments has been developed and used in past US research, and these US instruments are as diverse as they are numerous (Lucas, 1973; Noland & Seward, 1974; Swanson, 1974; Schultz & Slevin, 1975; Schewe, 1976; Pearson, 1977; Bailey & Pearson, 1983; Ives, Baroudi, & Olsen, 1983; Barki & Huff, 1985; Raymond, 1985; Raymond, 1987; Baroudi & Orlikowski, 1988; Montazemi, 1988; Tait & Vessey, 1988; Doll & Torkzadeh, 1988; Galletta & Lederer, 1989; Tan & Lo, 1990). Moreover, the scales from which these instruments are constructed lack theoretical basis (Shirani, Aiken, & Reithel, 1994; Sanders & Garrity, 1995). In summary, US research in IS is plagued by many problems, including the lack of consensus on a conceptual definition of the US construct, the lack of agreement on how US should be measured, and the inconsistent and even contradictory results that have been reported over the past two decades. The core reason for these problems and the resulting lack of progress in this area of research seems to be that, while much effort has been expended on the measurement of US, there has been very little work on the construct itself. Because of this, some IS researchers have called for a richer conceptual foundation for the US construct (Melone, 1990). In response to this call, Sanders and Garrity (1995) extended the model of IS Success developed by DeLone and McLean (1992) by identifying four dimensions of US: Task Support Satisfaction, Quality of Worklife Satisfaction, Interface Satisfaction, and Decision Making Satisfaction. The DeLone / McLean model, as modified by Sanders and Garrity, is presented in Figure 1. The four dimensions Sanders and Garrity (1995, p. 18) identified are defined as follows: • Task Support Satisfaction measures the fit between the job and the computer system. Items for this scale attempt to measure the functionality of the system in terms of how the system helps the individual to get a job done and fulfill task requirements. • Quality of Worklife Satisfaction measures how a computer system affects an individual’s quality of worklife and job satisfaction. Items for this scale attempt to measure whether the system supports the social needs, intellectual needs, and/ or physiological requirements of the individual in the context of job related activities. • Interface Satisfaction measures the quality of the computer system interface. Evaluation focuses on the characteristics of the interface in terms of presentation, format, and efficiency. Items for this construct attempt to determine whether Figure 1: The DeLone/McLean Model of IS Success, as modified by Sanders and Garrity (1995). 38 Spring • 1998 Information Resources Management Journal Vol. 11, No. 2 the outputs are arranged logically, the presentation media is acceptable, and/or the information is readily accessible. • Decision Making Satisfaction measures how well a system supports decision and problem solving activities. Items for this construct attempt to determine whether the system supports the individual in recognizing problems, structuring problems, and/or making decisions related to the goal of controlling some business process.1 Support Satisfaction, Quality of Worklife Satisfaction, Interface Satisfaction, and Decision Making Satisfaction is relabeled “Dimension,” because each of these dimensions could be related to satisfaction or dissatisfaction. And finally, note that the term “User Satisfaction” is changed to the more generic term, “User Affective Response” (UAR), allowing for the user’s response to be either satisfaction or dissatisfaction (Woodroof & Kasper, 1996). The model presented here extends the DeLone / McLean model by including notions of IS process satisfaction and outcome satisfaction, as well as dissatisfaction. Concerning the notion of dissatisfaction, Woodroof and Kasper (1996) have shown that US in IS may be a separate construct from IS user dissatisfaction (UD), and the wording of IS satisfaction instruments (whether positively or negatively) can significantly impact a user’s affective response. Concerning the notions of process and outcome, a user’s satisfaction with the process of an IS (how easy it is to learn and use) may be significantly different from that user’s satisfaction with the outcome of an IS (output in the form of generated documents and reports). Given these notions, each of the four dimensions identified by Sanders and Garrity can be considered along two additional dimensions: satisfaction / dissatisfaction and process / outcome. The addition of these dimensions (together with the dimensions identified by Sanders and Garrity) to the DeLone / McLean model, results in the model in Figure 2. Note, in Figure 2, the mappings of the process, outcome, satisfaction, and dissatisfaction combinations onto each of the four dimensions identified by Sanders and Garrity. Also note that the word “Satisfaction” in the terms Task A Theoretical Foundation for UAR A theoretical foundation for the UAR construct can be found in the organizational behavior literature. Landy and Becker (1987) identify three theories of motivation that use satisfaction as the dependent measure: equity, expectancy, and needs. Using the common dependent measure of satisfaction to integrate these three organizational behavior theories results in a well-founded and broad-based foundation for the study of UAR. The theoretical foundation for the User Interface dimension of the UAR construct in IS is presented in Figure 3. Figure 3 shows the User Interface dimension; however, any dimension of UAR can be mapped into the model. As shown in Figure 2, the Interface Dimension can be evaluated along the dimensions of process, outcome, satisfaction, and dissatisfaction. The attributes of an interface that research has shown to be important are: input/output attributes like readability of characters, color schemes used, layout of fields and text, and message feedback (Zmud et al., 1993), user friendliness attributes like response time, time required to learn, rate of errors and ease of recovery, and retention over time (Shneiderman, 1992), as well as information quality attributes Figure 2: An Extension of the DeLone/McLean Model of IS Success, based on the Sanders/Garrity (1995) Modification Spring • 1998 Information Resources Management Journal 39 Figure 3: Theory Foundation for the User Affective Response (UAR) Construct such as content, accuracy, and timeliness (Pearson, 1977).

Thus, equity theory emphasizes efficiency. Those Equity (or inequity) is the result of an individual’s users who have considerable interaction with the IS (i.e. entry evaluation of his or her inputs and rewards in comparison to clerks) may give added importance to the efficiency with another’s inputs and rewards. People appraise rewards in which the processes produce the outputs. Process facets terms of their fairness (Locke & Latham, 1990). If a discrepwould include the ease of learning and using an application, ancy is perceived between one’s efforts and rewards compared recalculation speed, refresh rate, and error recovery rate. to another’s efforts and rewards, the individual is motivated to Expectancy Theory — Outcome reduce this discrepancy. As Figure 3 shows, one’s perception of fairness is also moderated by one’s cognitive development. Expectancy theory focuses attention on outcome. Ex“People who have attained high levels of cognitive developpectancy theory posits that individuals consider alternative ment are better able to apply equity propositions than are those outcomes, analyze the costs and benefits of each outcome, and who have not achieved these levels” (Landy & Becker, 1987, choose an outcome that maximizes their utility. As shown in p. 16). There is evidence that equity in the mind of an Figure 3, affecting this decision are valence — the strength of individual is continually being recalculated and reassessed one’s preference for an outcome, and expectations — the (Greenberg & Ornstein, 1983). It follows that UARs ebb and likelihood that a particular outcome will occur. Likewise, flow based on one’s equity recalculations. valence and expectations affect UAR. If a user’s valence is In an information systems context, equity theory focuses high, UARs are affected depending upon how strongly the attention on the fairness of the process. A user’s perception outcome is expected and whether the outcome actually occurs. of the inputs required and the results obtained using one In an IS context, expectancy theory emphasizes the system are compared to the inputs required and the results effectiveness of the outcome. For most managers who rely on obtained by others using other systems. Inputs are what a user IS to support decisionmaking, outcomes (generated docu40 Spring • 1998 Information Resources Management Journal Vol. 11, No. 2 ments and reports) are the very reason for the existence of an IS. The importance of the layout and format of reports to decision makers is well documented (Swanson, 1974; Gallagher, 1974; Igersheim, 1976; Zmud, 1979; O’Reilly, 1982; Jenkins & Ricketts, 1985). To many users (upper management and users who do not interact very often with the IS), the outcome of an IS is more important than the processes that produced the outcome. Both the perceived efficiency of the process and the effectiveness of the outcome have an impact on UAR, and the effects of both equity (process) and expectancy (outcome) are moderated by needs. Both process and outcome must be considered in light of users’ needs. Needs Theory Needs theory is primarily based on the works of Maslow, Alderfer, and Herzberg. All three agree that there are “need levels,” although they disagree on the number of levels and the categorization of needs. They also view satisfaction differently. Maslow introduces a satisfaction-progression dimension, Alderfer adds a dissatisfaction - regression component, and Herzberg, in his two-factor theory, discusses satisfaction and dissatisfaction as two different constructs (Herzberg, Mausner, Peterson, & Capwell, 1957). Landy and Becker (1987) stress the cognitive element in needs theory by arguing that individuals create their own unique needs categories. As seen in Figure 3, the creation of these needs categories is influenced by an individual’s cognitive abilities, experience, and the situation in which he or she works. Because individuals construct their own unique needs categories, any evaluation of UAR must consider needs theory. In summary, the notions of process and outcome have roots in foundational theories of organizational behavior, and this provides a basis from which to consider the impact of these notions on user responses to an IS. Although theory suggests that these notions impact user responses to an IS, process and outcome do not necessarily have an equivalent impact. For example, users who have considerable interaction with the IS (i.e., entry clerks) may give added importance to the efficiency with which the processes produce output. Also, in some group decision support systems, the process by which the decisions are made may take precedence over the decision itself. Alternatively, there are situations where the outcome is considered more important than the process. There are some application environments where the outcome is considered so important that a frustrating process will be tolerated. Here, outcome dominates process in the UAR evaluation. One example is the current state of equation editors. Most are very tedious to use and require disproportional amounts of computer resources, yet many find the professional looking output to be worth the frustrating process. US and UD In Figure 3, US and UD are shown as related but separate constructs. That US and UD are separate constructs is also Spring • 1998 suggested by equity, expectancy, and needs theories and supported by both empirical and anecdotal evidence. In fact, depending upon the theory, US or UD may be the more salient. In terms of equity theory, the more salient of the two in an IS context is UD. This is a result of overselling the capabilities of a system. Wittingly or unwittingly, information systems are often oversold and users are rarely pleasantly surprised by the efficiency of the system that is actually delivered. In this way, US is not increased because the system simply performs as the designer claimed it would. Rather, users become dissatisfied when the system fails to meet their understanding of the designer’s claims. In expectancy theory, US and UD depend upon the combination of expected outcome and valence. Combining expected or unexpected outcomes with high or low valence produces four possibilities: 1) high valence and expected outcomes; 2) high valence and unexpected outcomes; 3) low valence and expected outcomes; and 4) low valence and unexpected outcomes. These are shown in Table 1. As Table 1 shows, only the high valence situations, affect US and UD. Only when the user has a high desire for a particular outcome is US or UD affected. If the user has no preference for a particular outcome, neither US nor UD is affected. Assuming high valence, US is obtained when the user has low expectations of realizing the outcome, and yet the outcome is realized. Conversely, UD occurs when a user strongly desires an outcome, fully expects to realize the outcome, and yet the outcome does not materialize. Consider the following example. Suppose a decision is to be made about an operating system. DOS is currently in use, but a move is underway to move to either UNIX or Windows NT. If the user has no preference for either UNIX or Windows NT, then neither US nor UD will be associated with the decision. On the other hand, if the user has a strong preference for one of these operating systems, either US or UD will be associated with the outcome. A user who strongly wants to move to Windows NT, but who has low expectations of this occurring, will experience some degree of US if Windows NT is chosen. Conversely, the selection of Windows NT will produce UD in those who had a strong preference for UNIX and who fully expected it to be chosen. In related empirical work, Avery and Jones (1985) show that reward and punishment are not points on a single continuum, but are two independent constructs. The factors that Valence (desire for outcome) High High Zero Zero Expectancy (likelihood of outcome) High Zero High Zero Outcome Occurred Outcome Did Not Occur Zero US High US Zero US Zero US High UD Zero UD Zero UD Zero UD Table 1: Valence and Expectation Combinations Information Resources Management Journal 41 are considered rewards are not necessarily the same factors as those whose absence defines punishment. Likewise, the factors that produce satisfaction are not necessarily the same factors as those whose absence produces dissatisfaction. Locke and Latham (1990) suggest one possible explanation for the believed nonsymmetrical relationship of satisfaction and dissatisfaction. Human beings often assume too much credit when an outcome is successful and too little blame when an outcome is not successful. Because success is often attributed to one’s own efforts, when a successful outcome is obtained, higher satisfaction results (Locke & Latham, 1990). Conversely, when an unsuccessful outcome occurs, dissatisfaction does not necessarily occur because humans tend to attribute unsuccessful outcomes to others, discounting the contribution of their own shortcomings to the failure. Expectancy theory also suggests that satisfaction and dissatisfaction are independent constructs. For example, Landy and Becker (1987, p. 20) write, ...when positive outcomes are involved, more is better. The same relationship does not hold, however, when negative outcomes are involved. The decision process seems to be much more primitive. When negative outcomes are involved, it does not seem to matter how negative they are. In other words, the extent of negativity is not related to the force to avoid that outcome — more is not worse. The case of negative outcomes seems to be all or none. Likewise, needs theory points to the nonsymmetrical relationship between satisfaction and dissatisfaction. In fact, this is the essence of Herzberg’s two-factor theory (Herzberg, et al., 1957). Despite its virtual dismissal as a theory of motivation, Herzberg’s work has merit as it relates to the constructs of satisfaction and dissatisfaction. Indeed, one of the criticisms of Herzberg’s two-factor theory is that it focuses on “satisfaction” rather than on the actual motivation of an employee (Szilagyi & Wallace, 1987). In fact, Herzberg considered satisfaction and dissatisfaction to be two different constructs. In IS, US and UD seem to be two separate unipolar constructs. The items or situations that contribute to US are not necessarily the same as those that promote UD. Empirical results support this contention (Woodroof & Kasper, 1996). Integrating equity (process) and expectancy (outcome) theories with US and UD results in a four category classification scheme shown in the center of Figure 3: US and UD with a process and US and UD with an outcome. Needs are nested within each of these four categories, and may differ with the particular IS situation. Implications measuring UAR, two phenomena are apparent: 1) the outcome-oriented questions far outnumber the process-oriented questions, and 2) the positively-framed questions far outnumber the negatively-framed questions. Without adjustment, this can produce misleading results. Consider, for example, the “overall” satisfaction statistics provided by Doll and Torkzadeh (1988). According to their measures, an overall satisfaction score of 49 or more would indicate that a user was satisfied with an application, while an overall satisfaction score of less than 49 would indicate that a user was not satisfied with an application. However, because of the disproportionate weighting of process and outcome questions (less than 20% of the questions are related to process), the scores are inconclusive. For example, it is possible for a user to respond with low satisfaction to an application’s outcome, high satisfaction with the process of an application, and yet have a low overall US score on this instrument. Summary and Conclusions Research on users’ affective responses to information systems has suffered from a lack of conceptual development. This paper proposes such a foundation, integrating three established organizational behavior theories. This conceptual foundation provides a framework for studying UAR. The framework is significant because it integrates theories of satisfaction and categories of IS support, identifying process and outcome satisfaction and dissatisfaction as salient to UAR. The contribution of this paper may be seen in three ways. First, for information systems to be considered successful, they must be both effective (outcome) and efficient (process). When studying user responses to an IS, it is important to consider the potential impact that the notions of process and outcome have on US and UD. Second, research on the development of future instruments should consider the mix and weighting of process-oriented and outcome-oriented questions. Finally, the conceptual development of this paper has IS design implications, suggesting that information systems should be designed to enhance the user’s process and outcome satisfaction, or perhaps a more realistic goal, to reduce the user’s process and outcome dissatisfaction. Endnote 1 According to Sanders and Garrity (1995, p. 6-7), “Decision making satisfaction is related to task support satisfaction, but there is a difference in terms of focus and details... Whereas task support satisfaction applies to both managers and non-managers, decision making satisfaction focuses on personnel that primarily have decision making responsibilities.” In reviewing most of the more popular instruments 42 Spring • 1998 Information Resources Management Journal Vol. 11, No. 2 References Avery, R.
