Understanding the dynamics of information technology implementation: The case of clinical information systems

The ultimate intent of this dissertation was to broaden and strengthen our understanding of IT implementation by emphasizing research efforts on the dynamic nature of the implementation process. More specifically, efforts were directed toward opening the "black box" and providing the story that explains how and why contextual conditions and implementation tactics interact to produce project outcomes. In pursuit of this objective, the dissertation was aimed at theory building and adopted a case study methodology combining qualitative and quantitative evidence. Precisely, it examined the implementation process, use and consequences of three clinical information systems at Jackson Memorial Hospital, a large tertiary care teaching hospital.^ As a preliminary step toward the development of a more realistic model of system implementation, the study proposes a new set of research propositions reflecting the dynamic nature of the implementation process.^ Findings clearly reveal that successful implementation projects are likely to be those where key actors envision end goals, anticipate challenges ahead, and recognize the presence of and seize opportunities. It was also found that IT implementation is characterized by the systems theory of equifinality, that is, there are likely several equally effective ways to achieve a given end goal. The selection of a particular implementation strategy appears to be a rational process where actions and decisions are largely influenced by the degree to which key actors recognize the mediating role of each tactic and are motivated to action. The nature of the implementation process is also characterized by the concept of "duality of structure," that is, context and actions mutually influence each other. Another key finding suggests that there is no underlying program that regulates the process of change and moves it form one given point toward a subsequent and already prefigured end. For this reason, the implementation process cannot be thought of as a series of activities performed in a sequential manner such as conceived in stage models. Finally, it was found that IT implementation is punctuated by a certain indeterminacy. Results suggest that only when substantial efforts are focused on what to look for and think about, it is less likely that unfavorable and undesirable consequences will occur. ^

The impact of information technology on organizations: A study of enterprise resource planning system influences on job design and organizational culture

The primary purpose of this research is to study the linkage between perceived job design characteristics and information system environment characteristics before and after the replacement of a legacy information system with a new type of information system (referred to as an Enterprise Resource Planning or ERP system). A public state University implementing an academic version of an ERP system was selected for the study. Three survey instruments were used to examine the perception of the information system, the job characteristics, and the organizational culture before and after the system implementation. The research participants included two large departments resulting in a sample of 130 workers. Research questions were analyzed using multivariate procedures including factor analysis, path analysis, step-wise regression, and matched pair analysis. ^ Results indicated that the ERP system has introduced new elements into the working environment that has changed the perception of how the job design characteristics and organization culture dimensions are viewed by the workers. The understanding of how the perceived system characteristics align with an individual's perceived job design characteristics is supported by each of the system characteristics significantly correlated in the proposed direction. The stronger support of this relationship becomes visible in the causal flow of the effects seen in the path diagram and in the step-wise regression. The perceived job design characteristics aligning with dimensions of organizational culture are not as strong as the literature suggests. Although there are significant correlations between the job and culture variables, only one relationship can be seen in the causal flow. ^ This research has demonstrated that system characteristics of ERP do contribute to the perception of change in an organization and do support organizational culture behaviors and job characteristics. ^

Managing Strategic Change

The essay - Managing Strategic Change – by K. Michael Haywood, Associate Professor, School of Hotel and Food Administration, University of Guelph, is initially characterized by Haywood as: “The ability to manage strategic change is critical for hospitality industry executives today. Executives must be capable of creating a vision of the future and implementing its direction. The author gives avenues for that management process.” “The effective management of strategic change is the major challenge confronting hospitality executives,” says Associate Professor Haywood. “Responding to a rapidly changing business environment and constantly evolving competitive threats and opportunities requires executives who can anticipate and plan for change.” According to Professor Haywood, the management of strategic change is a future imperative for hospitality executives. Implementing those changes will be even more difficult. “Survival and growth for many hospitality firms during the next decade will depend on the development of new strategic visions which can provide significant competitive advantages,” he says. “Strategies for managing costs and technology will be central to this task,” Haywood expands the thought. Haywood suggests two primary types of change hospitality executives should be aware of. First, is change that is anticipated, anticipatory change. Second, is the other more crucial type of change, strategic change in the face of crisis, or simply stated, reactive change. Professor Haywood describes the distinction between the two. In describing the approach that should be implemented in responding to an anticipatory change, Haywood says, “If time permits, and change is to be introduced gradually, pilots and trials should be run to assess the impact of the new strategy on the organization. These trials are used to create pockets of commitment throughout the corporation, build comfort levels with the new approach, and neutralize or win over potential opposition.” There are the obvious advantages to using an approach like the one described above, but there are disadvantages as well. Haywood discusses both. In addressing reactive change, Haywood offers that the process is a more - time is of the essence – condition, and that strong leadership and a firm hand on employee control is imperative. “Personal leadership, tough-mindedness, the willingness to ruthlessly abandon the familiar and the past, and the use of informal strategic levers are the hallmarks of sterling executive performance in such periods,” he says. “All these changes involve substantial technical, financial, and human risks,” Haywood wants you to know. “In order to make them, and still remain competitive, hospitality and travel-related corporations require executives capable of creating a vision of the future, able to sell that vision to their employees, and tough-minded enough to implement strategies to make the vision a reality.”
