Vol. 8, No.2 Systems Theory and Information Resources Management: Integrating Key Concepts RAYMOND McLEOD, JR. Texas A&M University Since the introduction of the computer as a business tool some forty years ago, its role in the firm has become increasingly complex. In the middle of this evolving complexity is the person who has the greatest responsibility for computer use in the firm—the chief information officer, or CIO. The 1980s saw an ascension in the CIO’s status within the firm, reaching a position of parity with vice presidents of other functional areas. The 1990s, however, are seeing indications that the CIO’s responsibility is eroding. Firms are beginning to pursue strategies that disburse more and more of their information resources throughout the organizational units, and give information processing responsibilities to outsourcers. If firms are to engage in strategic planning for their information resources and engage in information resources management, there must be a clear understanding of the forces that influence computer use and the role of the CIO in managing these forces. As a means of achieving such an understanding, the author explores the possible application of systems theory. The result is a normative structure that makes it possible to evaluate the extent to which a firm practices information resources management, and to project future trends in the role of such component elements as the CIO and the information systems unit. The management information systems (MIS) field has never been short on concepts—views in people’s minds of phenomena. In fact, MIS itself is a concept—a view of how the computer can be used to provide managers with information for decision making (Aron, Dearden, Zani). The decision support system (DSS) is also a concept (Gorry and Scott Morton, Sprague). Since computer and management scientists have been free to view these systems as they see fit, there has always been a certain amount of disagreement concerning the concepts and their interrelationships. The 1980s saw interest in computer use shift from applications that meet individual needs to those designed to meet organizational needs, and the idea that information can be used to achieve and maintain an advantage in the marketplace led to the concept known as competitive advantage (Porter and Millar). In a like manner, the concept of strategic planning for information resources, or SPIR, was devised to describe the way that the firm’s executives develop long-range plans describing how their information resources will be used to support the attainment of the firm’s strategic objectives (King, 1988). During this same period, a concept emerged that captured the idea of a person on the executive level having primary responsibility for all of the firm’s information resources. This idea assumed more than simply a title, and became known as the chief information officer (CIO) concept (Rockart, 1982). These concepts—competitive advantage, SPIR, and the CIO—all reflect organizational views of computer use. Another concept of the same type, perhaps the loftiest of all in that it was intended to represent a global view of computer use at the top-management level, was named information resources Manuscript originally submitted December 20, 1993; Revised May 18, 1994; Accepted July 27, 1994 for publication. Spring • 1995 Information Resources Management Journal 5 management, or IRM. Several different views of IRM have been offered (Guimaraes; March and Kim; Cheng and Kanabar), but essentially it recognizes that data and information are given as much management attention as such physical resources as personnel, materials, machines, and money. Another concept that came to fruition during the 1980s probably stimulated more interest than all the others combined. This was the concept of end-user computing (EUC), which captured the capability of users to actively contribute to the development of their own computer-based systems (Yaverbaum). Although EUC would appear to focus on individual users, firms quickly recognized the potential impact on the organization. The interest in EUC grew so quickly that many firms lost control of their information resources and took inappropriate actions due to lack of proper technical training (Alavi and Weiss; O’Donnell and March). In response to this loss of centralized control, firms modified their organizational structure and enacted policies and practices aimed at ensuring the growth of EUC in a coordinated way (Munro, Huff, and Moore; Pyburn; Rockart and Flannery; Simmons, Burbridge, Harris, and Ames) So, end-user computing had its organizational implications. Although one would suspect that all of these organizationally based concepts affect each other in some way, very little study has been aimed at identifying and explaining the interrelationships. Ein-Dor and Segev (1988) explained the relationship of EUC and IRM, and Henderson and Treacy (1986) related EUC to competitive advantage. But, there has been no effort aimed at establishing a structure to encompass all of the concepts. If all of the concepts are interrelated, practically everyone in the firm would benefit from knowing what those interrelationships are. The firm’s executives would benefit by better understanding the importance of strategic planning for the firm’s information resources in achieving IRM, the need to accomodate end-user computing in IRM, and the role that the CIO plays in IRM. The CIO would benefit by understanding the need to participate with other executives in all aspects of IRM, and the role of the information systems (IS) unit in EUC. In a like manner, computer users throughout the firm would benefit by understanding the influence of strategic planning on their developmental efforts, and the way that responsibilities are to be shared with IS. Whereas several approaches to exploring the interrelationships between these organizational views of computer use and responsibility no doubt are possible, one that would be expected to hold substantial promise is systems theory. Systems theory is appropriate because it has provided the basis for the design of computer-based systems. The computer is a physical system, as are the firm, and the people within the firm who use the computer. Computer applications take the form of input-processing-output modules that incorporate feedback mechanisms. Also, such methodologies as the system development life 6 Spring • 1995 cycle, prototyping, and rapid application development (RAD) are expressions of an application of systems theory known as the systems approach. The task of this paper is to use systems theory as a means of understanding the constituent relationships within IRM, and projecting those relationships as they apply to the CIO and IS. Systems Theory Systems theory defines phenomena in systems terms. Ackoff (1971) recognized that a system must consist of multiple component parts by definining a system as “a set of interrelated elements.” Churchman (1968) recognized that the elements exhibit goal-oriented behavior by stating that a system “is a set of parts coordinated to accomplish a set of goals.” Open and Closed Systems Systems can be classified based on their relationships with their environments. The two types are open systems and closed systems. Andrew (1965) distinguished between the two as follows (Andrew’s italics): A closed system is isolated from its environment. There is no import or export of material and its final state is unequivocally determined by its initial conditions. An open system, on the other hand, exchanges materials with the environment and has the basic characteristic of self-regulation. System Elements An open system must include component elements that facilitate an interaction with its environment and contribute to the self-regulation. Von Bertalanffy (1962) used the diagram of a simple feedback model in Figure 1 to illustrate the basic structure of an open system. As the system regulates itself so as to achieve its goals, it seeks to maintain a steady state, a constant composition that is achieved by a continuous exchange and flow of component material. This steady state is also known as the goal state (Andrew). Source: Ludwig von Bertalanffy, General Systems Theory: A Critical Review. General Systems (1962), p.6. Figure 1: An Open System Information Resources Management Journal Vol. 8, No.2 The feedback mechanism is essential to achieving the goal state. Johnson, Kast, and Rosenzweig (1967) state that “any system, if it is to achieve a predetermined goal, must have available to it at all times an indication of its degree of attainment. In general, every goal-seeking system employs circuits, or feedback.” Systems Hierarchies Systems can exist in a hierarchical array, with a system on one level being incorporated in the system immediately above. When attention is directed at a level, the system immediately above is the supersystem or suprasystem, and the system immediately below is a subsystem. Although some systems assume a greater status than others because of their position within the hierarchy, it is important to recognize that systems on all levels have the same basic structural composition. This means that systems theory can be applied just as well at the bottom level in the hierarchy as at the top. General Systems Theory Applied in its broadest sense, systems theory is known as general systems theory (GST). GST is the view that all phenomena can be explained in systems terms, and its founder was Ludwig von Bertalanffy, a German biologist (von Bertalanffy). Another contributor was Kenneth E. Boulding, an American economist and social scientist, who recognized that the purpose of GST is to “provide a framework or structure of systems on which to hang the flesh and blood of particular disciplines and particular subject matters in an orderly and coherent corpus of knowledge” (Boulding). Since the pioneering work of von Bertalanffy and Boulding, GST has been applied a variety of ways. For example, Forrester (1958); Brewer and Rosenzweig (1961); and Katz and Kahn (1966) used GST to describe business organizations. Duncan (1964); Hopeman (1969); Thompson (1975); Brix (1980); Kefalas (1980); and Hambrick (1981) applied GST to the environments in which business organizations can be positioned. Viewing the Firm as a System The efforts of systems theorists show that business organizations can be explained in systems terms. When someone regards a phenomenon as a system, it is known as taking a systems view. Figure 2 illustrates such a systems view of the firm. When a manager takes a systems view, the management task boils down to four basic steps (Tilles): 1. 2. 3. 4. Define the company as a system. Establish system objectives. Create formal subsystems. Integrate the subsystems. Spring • 1995 Figure 2: The Firm as a System Unfortunately, friction can exist among subsystems due to the fact that they often have different and partially incompatible requirements (Etzioni). As a means of avoiding such conflict, Etzioni recommends that subsystem managers recognize that intersubsystem concessions are necessary. Andrew (1965) also recognizes the need to make concessions. He observes that some subsystem goals can be achieved without affecting the other subsystems, but other goals require the subsystems to adapt to each other. Subsystem goals, therefore, must be compatible. A subsystem that stays in its goal state at the expense of the other subsystems may be extruded from the system. The reality of subsystem friction in business organizations does not diminish the value of systems theory. To the contrary, the theory provides a means of projecting how the organization will deal with such friction. According to Andrew, “The system model makes it possible to predict the likelihood of such ‘shape-ups’ and the actual purpose they serve in a given instance” (Andrew). Competitive Advantage Managers seek to gain a favorable position for their firms within their environments—a status called competitive advantage. Such an advantage can be gained in many ways, such as quality products, low prices, and fast service. Recently, management has become aware of the potential of information Information Resources Management Journal 7 Figure 3: An Environmental Systematic Construct as a competitive weapon. Most of the descriptions of how information can be used to achieve competitive advantage have focused on the firm’s customers (Johnston and Vitale). Although obviously effective, this customer-oriented approach is rather narrow. Systems theory provides the basis for taking a broader view. The firm’s environment contains elements in addition to the firm’s customers, as shown by the diagram in Figure 3. The five major functional areas of the firm, in the center, are connected to the environmental elements by resource flows. Each functional area has primary responsibility for resource flows to and from certain environmental elements, and the IS function assists the other functional areas in establishing and maintaining information flows. Competitive advantage can be achieved by improving the information flow between the firm and its each of the environmental elements. For example, an improved information flow between the firm and its suppliers will ensure that raw materials are available when needed; an improved flow between the firm and its stockholders and owners, and the financial community will ensure that funds are available when needed; an improved flow between the firm and labor unions will ensure a continuing supply of skilled workers; and so on. A systems view enables the firm’s executives to see that relationships with each of the environmental elements can contribute to competitive advantage. Further, it becomes clear that information flows play key roles in these relationships. Systems theory contributes a systematic, rather than haphazard, approach to the design of environmental information systems. 8 Spring • 1995 Strategic Planning for Information Resources In his classic study of management systems, Anthony (1965) described strategic planning as the process of deciding on objectives of the organization, on changes in the objectives, on the resources used to attain the objectives, and on the policies that govern the acquisition, use, and disposition of the resources. Functional Strategic Plans It is not unusual for the functional areas of the firm to engage in their own strategic planning, and during the late 1970s and early 1980s, the prescribed approach was to gear the functional plans to the strategic plan of the firm. In describing how IS followed this top-down approach, King explained that “The heart of MIS strategic planning is the process through which the organizational strategy set is transformed into a set of system objectives, system constraints, and system design principles which comprise the MIS strategy set” (King, 1978). This top-down influence on strategic plans for IS worked well until the firm’s executives recognized the potential contribution of the computer as a competitive weapon. The executives began to evaluate their information resources prior to finalizing the firm’s strategic plan. Now, in addition to the information resources being influenced by the strategic plan, the plan is influenced by the information resources. King (1988) used the term strategic planning for information resources (SPIR) to describe this approach. Figure 4 illustrates the two-way relationship that exists between the firm’s strategic plan and the resources of each functional area. The Chief Information Officer (CIO) Information Resources Management Journal Vol. 8, No.2 Figure 4: A Participatory Approach to Developing the Firm’s Strategic Plan As the firm’s executives began to recognize the strategic value of information, they also began to regard the top computer manager as an executive. This recognition reflects what is known as the CIO concept. According to this concept, the top-level IS manager participates equally with top-level managers of other functional areas in making the firm’s strategic decisions (Rockart, 1982). When a systems view is taken of the CIO concept in today’s world of distributed information resources, it becomes obvious that responsibility for managing those resources should not be borne by a single individual. Rather, the key decisions should be made jointly by executives from all of the firm’s functional areas. This joint responsibility is an important consideration. The CIO cannot prepare a strategic plan for information resources without a knowledge of the strategic plans of the other functional areas (Evans and Hague). Conversely, the functional managers cannot engage in their own strategic planning without a knowledge of the capabilities of IS to support their plans. A reciprocal planning relationship therefore exists among the functional areas, as shown in Figure 5. End-User Computing As users throughout the firm saw the benefits of doing their own computer work, the functional areas then began establishing their own IS operations, complete with computer specialists and often utilizing minicomputers and even mainframes. This rapid growth in end-user computing too often turned into a nightmare. The firms’ executives realized that they had lost control over the information resources, and were forced to take actions designed to provide the necessary constraints. Two of these actions were organizational in nature. The first action involved the MIS steering committee, the group within the firm that enforces the firm’s computerrelated policies, and oversees the various developmental ef- Spring • 1995 Figure 5: A Joint Approach to Developing Functional Strategic Plans forts. The executives began to charge their MIS steering committees with enterprise-wide responsibility for establishing policies concerning systems development, computer acquisition, and computer use (Doll and Torkzadeh). The second action saw firms implement information centers as a means of controlling the acquisition of hardware and software. Rather than provide everyone with their own resources, the information center includes the hardware, software, and technical assistance that a person needs when engaged in end-user computing. By giving the MIS steering committee the responsibility for achieving the firm’s strategic plan for information resources, and providing users with the necessary resources within an organizational setting, firms were able to achieve and maintain control over end-user computing. Such actions are important ingredients in the strategic plan for information resources. An Integrative IRM Feedback Model The organizationally based topics (competitive advantage, SPIR, the CIO, EUC, and IRM) discussed above do not all exist on the same hierarchical level. IRM can be regarded as the system, with the other concepts existing as subsystems. The subsystems are connected in a chain-line fashion, as shown in the IRM model illustrated in Figure 6. The numbers in the model correspond to the sections below. 1. Competitive Advantage The environment of the firm provides the context for all of the firm’s activities. The firm interfaces with the environmen- Information Resources Management Journal 9 Figure 6: An IRM Model 10 Spring • 1995 Information Resources Management Journal Vol. 8, No.2 tal elements by means of resource flows. These flows are external influences on the firm’s activities. The firm strives to achieve a competitive advantage in this environment. The firm remains alert to environmental activity by engaging in business intelligence. This intelligence is made available to those persons in the firm who are responsible for certain of the firm’s environmental interfaces. The executive committee is a primary user of business intelligence. 2. Strategic Business Planning The executive committee engages in strategic business planning, and considers the levels of support that can be provided by the functional areas. These functional resources represent internal influences. The CEO serves as committee chairperson. The top-level managers of the functional areas comprise the remainder of the membership. The CIO is a member, as are the vice-presidents of finance, human resources, manufacturing, and marketing. One of the tasks of the strategic business plan is to chart the future course of the firm as it seeks to achieve and maintain a long-term competitive advantage. 3. Strategic Planning for Information Resources The firm’s strategic business plan influences the strategic plans developed for each of the functional areas. Each functional plan is coordinated with the plans of the other functional areas. The CIO participates in the planning for all of the functional areas as required. In terms of the strategic plan for information resources, the CIO may play the primary role. 4. MIS Steering Committee It is the task of the MIS steering committee to ensure that the strategic plan for information resources is accomplished. The committee performs its duties by overseeing all aspects of computer use, and applying policies and standards as needed. Particular attention is focused on the system development life cycles of ongoing projects, ensuring that the systems are implemented as intended. 5. Information Resources The strategic plan for information resources describes how user needs will be satisifed by resources in three main locations—the central computing facility, user areas, and perhaps one or more information centers. Users who do not engage in end-user computing make use of the resources located in the central facility and, when present, in their own areas. Users who do engage in end-user computing make use of information resources in all three areas. IRM as an Open System environment, and consisting of a transformation process, a control mechanism, and feedback. The Environment The environment is that of the firm, and is the setting where competitive advantage is achieved. Transformation Process Information is gathered both within the firm and from its environment, and is transformed into plans, policies, and standards, which represent the system outputs. The outputs guide users and end-users as they use the information resources. Control Mechanism The control mechanism consists of the executive committee, supported by the MIS steering committee. Feedback Feedback flows keep management aware of the outcome of their planning and control efforts. • At the top of the model, feedback exists in the form of business intelligence, which keeps the executive committee informed concerning environmental activity, both current and projected. • In the center of the model, feedback is directed from the MIS steering committee to the executive committee, which uses the information in monitoring the performance of the firm in terms of the strategic business plan. • At the bottom of the model, feedback is directed from the information resources to the MIS steering committee, which uses the information in monitoring computer-related activity. IRM is therefore a system, with subsystems that achieve competitive advantage, prepare strategic plans, and manage the firm’s information resources. Application of the Theory Systems theory can be applied to the management of information resources in two ways. First, the IRM model can represent a normative framework that a manager can use to gauge the extent to which her or his firm is practicing IRM. Second, the theory can be used to study any of the IRM The model depicts IRM as an open system, existing in an Spring • 1995 Information Resources Management Journal 11 subsystems, or component concepts, for the purpose of understanding why they behave as they do and what their behavior might be, given certain stimuli. The IRM Model as a Normative Framework If a firm is to practice IRM in accordance with systems theory, its management will: 1. Recognize that the firm exists in an environment that exerts an influence on the firm’s activities. 2. Identify competitive advantage as an environmental objective of the firm. Such an objective will enable the firm to best serve all of the elements in the environment, excluding competitors. 3. Gather business intelligence, which keeps the firm informed of environmental activities. 4. Engage in strategic business planning, which takes into account the level of support that can be provided by all functional areas as the plans are made, and spells out how to achieve competitive advantage. 5. Engage in strategic planning for information resources, which considers the information needs of the entire firm, and spells out the firm’s policies in relation to end-user computing. 6. Designate a group within the firm, such as the MIS steering committee, to carry out the strategic plan for information resources. 7. Make information resources available to users who prefer to rely on IS for systems support, as well as to end-users who prefer to do some, or all, of their systems development work. These are the key ingredients to achieving IRM in terms of systems theory. In applying the ingredients to a particular firm, management must determine the extent to which each is carried out. Systems Theory as an Explanation of IRM Component Concepts Systems theory can explain any of the IBM component concepts in terms of how they should function. The CIO is an excellent candidate for such a study. The question of who in the firm should be responsible for its information resources is one that has persisted throughout the computer era (Thurston). However, the question is especially relevant today in view of changes that are taking place as many firms cope with the challenges of information resources management. Outsourcing, downsizing, and distribution of resources throughout the firm are all options that a firm can follow, and all have a profound effect on the CIO’s scope of responsibilities. The path that the CIO and IS follow during coming years will depend to a great extent on their power in relation to that of other functional areas. The Power Position of the CIO and IS 12 Spring • 1995 One way to achieve a position of power within an organization is to offer a product or service that others desire. Brix (1980) elaborates: The most important social attribute of an element, that is, a human being, a group or organization, is the possession of some desired good or service which can be dispensed as a surplus. This good or service must be in relatively short supply. In seeking a position of power within the organization, IS has an advantage in that information is recognized as one of the basic resources and, hence, has value. More importantly, information is seen as giving power. Miller (1972) hypothesized that the ability of a subsystem to provide information to the control unit of the system gives that subsystem a power advantage over the other subsystems. During the first thirty or so years of the computer era, IS was, for all practical purposes, the sole supplier of computerbased information. This power position was one of the main reasons for the ascension of the CIO to executive status during the mid-1980s. The thrill of accomplishment, however, was short-lived as end-user computing and other encroachments on IS responsibilities began to erode the CIO’s power base. The question today is just how far the erosion will go. In order for systems theory to provide an answer, IS must be evaluated in terms of its environment, management, objectives, inputs, transformations, outputs, and feedback mechanism. The IS Environment The IS environment consists of elements that exist outside and inside the firm. External Environment Using Hopeman’s (1969) classification, the external elements with which IS most often interacts include the government, competitors, and suppliers. Of these, only competitors appear to have a direct influence on the future role of IS in the firm. The competitors include outsourcers that can assume some portion of the IS workload, but the likelihood of this happening depends primarily on IS relationships with its internal environment. Internal Environment In its internal environment, IS interacts with peer organizations, such as other functional areas that use the information output, as well as groups on higher levels in the Information Resources Management Journal Vol. 8, No.2 organizational hierarchy, such as the executive committee and MIS steering committee. The task of IS is to avoid friction with the other units, and establish a power position in relation to them. Avoid Friction Friction can be avoided by pursuing a three-pronged strategy. The origin of each strategy, from systems theory, is identified in parentheses. 1. Ensure that IS goals are compatible with goals of user organizations (Andrew). 2. Identify users who have critical responsibilities in terms of the industry’s dominant environmental requirement, and make special efforts to ensure that those users receive the needed support (Etzioni, Hambrick). 3. Emphasize joint, rather than unilaterial, effort with users in systems development projects (Morgan). Achieve Power The CIO can achieve a position of power for IS by applying the two following recommendations while providing user support. 1. Understand the activities and needs of peer units (Brix). 2. Place a premium on information support for the firm’s executives, as in the form of executive information systems (Miller). Systems theory, therefore, identifies for the CIO the appropriate strategies for particular environmental elements. Some, such as those designed to avoid friction, emphasize cooperation. Others, such as those designed to achieve a position of power, are more aggressive in nature. IS Management The CIO should assemble a management team that can perform the control function in the IS system. Applied at the IS level, this activity consists of establishing objectives, creating subsystems within IS, and integrating the subsystems (Tilles). With the management team in place, its task is to keep IS on track in terms of its goal state (Andrew). IS Objectives IS management should establish objectives that are directly related to, and provide maximum support for, the objectives of the firm (Etzioni). Further, objectives should emphasize building positive relations with users rather than focusing strictly on the end products of those relations (Morgan). IS Inputs, Transformations, and Outputs Spring • 1995 The CIO and IS management team should assemble information resources that can outperform any other supplier, inside or outside the firm, in providing a quality information product at an attractive price. The quality product can be achieved, in part, by achieving higher levels of specialization within the IS staff (Katz and Kahn). The attractive price can be achieved by refraining from predatory pricing policies (Brix). IS Feedback Mechanism IS management should assemble a feedback mechanism that is capable of keeping themselves informed of IS performance in relation to its objectives (Johnson, Kast, and Rosensweig). Such a mechanism would take the form of a functional information system similar to those pioneered in marketing and more recently achieved in human resources. The Future of the CIO By applying the underlying systems theory, it is possible to prescribe certain strategies that the CIO can follow in solidifying his or her position, and the position of IS, in the firm. These are not the only strategies available to the CIO. Others, emphasizing components such as economic and behavioral considerations, should also be taken into account. If the CIO will follow the prescribed strategies, then he or she should continue to be included among the firm’s top-level executives, and IS should continue to be a major functional area. Conclusion IRM is an excellent candidate for the application of systems theory. IRM is a multi-dimensional phenomenon, subject to influences by the business environment. IRM has an objective, and the firm’s management team serves as the control mechanism to ensure that the objective is met. Feedback circuits keep management informed of IRM performance. It is unlikely that any other theory would capture the intricate nature of IRM as well as systems theory. Systems theory can also be used to explain subsidiary IRM concepts, such as the CIO. The CIO is a part of the control mechanism, serving on the executive committee, the MIS committee, and managing the IS unit. The CIO is a major role player in IRM, having a strong influence on the extent to which the key elements are achieved. Systems theory provides some prescriptions for CIOs to follow in solidifying their position as References a key executive in their firms. Ackoff, R. L. Towards a System of Systems Concepts.
