Management Information System Essay Organizations and Information Systems * Information technology and organizations influence one another * Complex relationship influenced by organization’s structure, business processes, politics, culture, environment, and management decisions The Two-Way Relationship between Organizations and Information Technology This complex two-way relationship is mediated by many factors, not the least of which are the decisions made—or not made—by managers. Other factors mediating the relationship include the organizational culture, structure, politics, business processes, and environment. What is an organization? * Technical definition: * Stable, formal social structure that takes resources from environment and processes to produce outputs. * A formal legal entity with internal rules and procedures, as well as a social structure * Behavioral definition: * A collection of rights, privileges, obligations, and responsibilities that is delicately balanced over a period of time through conflict and conflict resolution The Technical Microeconomic Definition of the Organization In the microeconomic definition of organizations, capital and labor (the primary production factors provided by the environment) are transformed by the firm through the production process into products and services (outputs to the environment). The products and services are consumed by the environment, which supplies additional capital and labor as inputs in the feedback loop. Figure 3-2 The Behavioral View of Organizations The behavioral view of organizations emphasizes group relationships, values, and structures. Figure 3-3 * Features of organizations * All modern organizations share some characteristics, such as: * Use of hierarchical structure * Accountability, authority in system of impartial decision-making * Adherence to principle of efficiency * Other features include: Routines and business processes and organizational politics, culture, environments and structures * Routines and business processes * Routines (standard operating procedures) Precise rules, procedures, and practices developed to cope with virtually all expected situations * Business processes: Collections of routines * Business firm: Collection of business processes Routines, Business Processes, and Firms All organizations are composed of individual routines and behaviors, a collection of which make up a business process. A collection of business processes make up the business firm. New information system applications require that individual routines and business processes change to achieve high levels of organizational p erformance. Figure 3-4 * Organizational politics * Divergent viewpoints lead to political struggle, competition, and conflict * Political resistance greatly hampers organizational change * Organizational culture: * Encompasses set of assumptions that define goal and product * What products the organization should produce * How and where it should be produced * For whom the products should be produced * May be powerful unifying force as well as restraint on change * Organizational environments: Organizations and environments have a reciprocal relationship * Organizations are open to, and dependent on, the social and physical environment * Organizations can influence their environments * Environments generally change faster than organizations * Information systems can be instrument of environmental scanning, act as a lens Environments and Organizations Have a Reciprocal Relationship Environments shape what organizations can do, but organizations can influence their environments and decide to chang e environments altogether. Information technology plays a critical role in helping organizations perceive environmental change and in helping organizations act on their environment. Figure 3-5 * Organizational structure * Five basic kinds of structure * Entrepreneurial: Small start-up business * Machine bureaucracy: Midsize manufacturing firm * Divisional zed bureaucracy: Fortune 500 firms * Professional bureaucracy: Law firms, school systems, hospitals * Adhocracy: Consulting firms * Other Organizational Features * Goals * Constituencies * Leadership styles * Tasks Surrounding environments How Information Systems Impact Organizations and Business Firms * Economic impacts * IT changes relative costs of capital and the costs of information * Information systems technology is a factor of production, like capital and labor * IT affects the cost and quality of information and changes economics of information * Information technology helps firms contract in size because it can reduce transaction costs (the cost of participating in markets). Outsourcing expands * Transaction cost theory Firms seek to economize on cost of participating in market (transaction costs) * IT lowers market transaction costs for firm, making it worthwhile for firms to transact with other firms rather than grow the number of employees The Transaction Cost Theory of the Impact of Information Technology on the Organization Firms traditionally grew in size to reduce transaction costs. IT potentially reduces the costs for a given size, shifting the transaction cost curve inward, opening up the possibility of revenue growth without increasing size, or even revenue growth accompanied by shrinking size. Figure 3-6 * Agency theory: * Firm is nexus of contracts among self-interested parties requiring supervision * Firms experience agency costs (the cost of managing and supervising) which rise as firm grows * IT can reduce agency costs, making it possible for firms to grow without adding to the costs of supervising, and without adding employees The Agency Cost Theory of the Impact of Information Technology on the Organization As firms grow in size and complexity, traditionally they experience rising agency costs. IT shifts the agency cost curve down and to the right, enabling firms to increase size while lowering agency costs. Figure 3-7 * Organizational and behavioral impacts * IT flattens organizations * Decision-making pushed to lower levels * Fewer managers needed (IT enables faster decision-making and increases span of control) * Postindustrial organizations * Organizations flatten because in postindustrial societies, authority increasingly relies on knowledge and competence rather than formal positions Flattening Organizations Information systems can reduce the number of levels in an organization by providing managers with information to supervise larger numbers of workers and by giving lower-level employees more decision-making authority. Figure 3-8 * Organizational resistance to change * Information systems become bound up in organizational politics because they influence access to a key resource information * Information systems potentially change an organization’s structure, culture, politics, and work * Most common reason for failure of large projects is due to organizational amp; political resistance to change Organizational Resistance and the Mutually Adjusting Relationship between Technology and the Organization Implementing information systems has consequences for task arrangements, structures, and people. According to this model, to implement change, all four components must be changed simultaneously. Figure 3-9 * The Internet and organizations * The Internet increases the accessibility, storage, and distribution of information and knowledge for organizations * The Internet can greatly lower transaction and agency costs * E. g.
