To understand the proper role of information systems one must examine what managers do and what information they need for decision making. We must also understand how decisions are made and what kinds of decision problems can be supported by formal information systems. One can then determine whether information systems will be valuable tools and how they should be designed.
This chapter has the purpose of leading the reader towards:
· An understanding of the different roles managers play and how marketing information systems can support them in these roles· An appreciation of the different types and levels of marketing decision making
· A knowledge of the major components of a marketing information system
· An awareness of the often under-utilised internal sources of information available to enterprises
· An ability to clearly distinguish between marketing research and marketing intelligence, and
· An understanding of the nature of analytical models within marketing information system.
The chapter opens with a wide-ranging discussion of the functions of management, the various types and levels of decision that marketing managers must make. This then comprises the first half of the chapter whilst the second pan deals with the main components of a marketing information systems.. Internal reporting systems, marketing research systems, marketing intelligence systems and analytical model banks are all discussed.
Clearly, information systems that claim to support managers cannot be built unless one understands what managers do and how they do it. The classical model of what managers do, espoused by writers in the 1920's, such as Henry Fayol, whilst intuitively attractive in itself, is of limited value as an aid to information system design. The classical model identifies the following 5 functions as the parameters of what managers do:
1 Planning
2 Organising
3 Coordinating
4 Deciding
5 Controlling
Such a model emphasises what managers do, but not how they do it, or why. More recently, the stress has been placed upon the behavioural aspects of management decision making. Behavioural models are based on empirical evidence showing that managers are less systematic, less reflective, more reactive and less well organised than the classical model projects managers to be. For instance, behavioural models describe 6 managerial characteristics:
· High volume, high speed work
· Variety, fragmentation, brevity
· Issue preference current, ad hoc, specific
· Complex web of interactions, contacts
· Strong preference for verbal media.
Such behavioural models stress that managers work at an unrelenting pace and at a high level of intensity. This is just as true for managers operating in the developing world as in the developed world. The nature of the pressures may be different but there is no evidence that they are any less intense. The model also emphasises that the activities of managers is characterised by variety, fragmentation and brevity. There is simply not enough time for managers to get deeply involved in a wide range of issues. The attention of managers increase rapidly from one issue to another, with very little pattern. A problem occurs and all other matters must be dropped until it is solved. Research suggests that a manager's day is characterised by a large number of tasks with only small periods of time devoted to each individual task.
Managers prefer speculation, hearsay, gossip in brief, current, up-to-date, although uncertain information. Historical, certain, routine information receives less attention. Managers want to work on issues that are current, specific and ad hoc.
Managers are involved in a complex and diverse web of contacts that together act as an information system. They converse with customers, competitors, colleagues, peers, secretaries, government officials, and so forth. In one sense, managers operate a network of contacts throughout the organisation and the environment.
Several studies have found that managers prefer verbal forms of communication to written forms. Verbal media are perceived to offer greater flexibility, require less effort and bring a faster response. Communication is the work of the manager, and he or she uses whatever tools are available to be an effective communicator.
Despite the flood of work, the numerous deadlines, and the random order of crises, it has generally been found that successful managers appear to be able to control their own affairs. To some extent, high-level managers are at the mercy of their subordinates, who bring to their attention crises and activities that must be attended to immediately. Nevertheless, successful managers are those who can control the activities that they choose to get involved in on a day-to-day basis. By developing their own long-term commitments, their own information channels, and their own networks, senior managers can control their personal agendas. Less successful managers tend to be overwhelmed by problems brought to them by subordinates.
Mintzberg suggests that managerial activities fall into 3 categories: interpersonal, information processing and decision making. An important interpersonal role is that of figurehead for the organisation. Second, a manager acts as a leader, attempting to motivate subordinates. Lastly, managers act as a liaison between various levels of the organisation and, within each level, among levels of the management team.
A second set of managerial roles, termed as informational roles, can be identified. Managers act as the nerve centre for the organisation, receiving the latest, most concrete, most up-to-date information and redistributing it to those who need to know.
A more familiar set of managerial roles is that of decisional roles. Managers act as entrepreneurs by initiating new kinds of activities; they handle disturbances arising in the organisation; they allocate resources where they are needed in the organisation; and they mediate between groups in conflict within the organisation.
In the area of interpersonal roles, information systems are extremely limited and make only indirect contributions, acting largely as a communications aid in some of the newer office automation and communication-oriented applications. These systems make a much larger contribution in the field of informational roles; large-scale MIS systems, office systems, and professional work stations that can enhance a manager's presentation of information are significant. In the area of decision making, only recently have decision support systems and microcomputer-based systems begun to make important contributions.
While information systems have made great contributions to organisations, until recently these contributions have been confined to narrow, transaction processing areas. Much work needs to be done in broadening the impact of systems on professional and managerial life.
Decision making is often seen as the centre of what managers do, something that engages most of a managers time. It is one of the areas that information systems have sought most of all to affect (with mixed success). Decision making can be divided into 3 types: strategic, management control and operations control.
Strategic decision making: This level of decision making is concerned with deciding on the objectives, resources and policies of the organisation. A major problem at this level of decision making is predicting the future of the organisation and its environment, and matching the characteristics of the organisation to the environment. This process generally involves a small group of high-level managers who deal with very complex, non-routine problems.
For example, some years ago, a medium-sized food manufacturer in an East African country faced strategic decisions concerning its range of pasta products. These products constituted a sizeable proportion of the company's sales turnover. However, the company was suffering recurrent problems with the poor quality of durum wheat it was able to obtain resulting in a finished product that was too brittle. Moreover, unit costs were shooting up due to increasingly frequent breakdowns in the ageing equipment used in pasta production. The company faced the decision whether to make a very large investment in new machinery or to accept the offer of another manufacturer of pasta products, in a neighbouring country, that it should supply the various pasta products and the local company put its own brand name on the packs. The decision is strategic since the decision has implications for the resource base of the enterprise, i.e. its capital equipment, its work force, its technological base etc. The implications of strategic decisions extend over many years, often as much as ten to fifteen years.
Management control decisions: Such decisions are concerned with how efficiently and effectively resources are utilised and how well operational units are performing. Management control involves close interaction with those who are carrying out the tasks of the organisation; it takes place within the context of broad policies and objectives set out by strategic planners.
An example might be where a transporter of agricultural products observes that his/her profits are declining due to a decline in the capacity utilisation of his/her two trucks. The manager (in this case the owner) has to decide between several alternative courses of action, including: selling of trucks, increasing promotional activity in an attempt to sell the spare carrying capacity, increasing unit carrying charges to cover the deficit, or seeking to switch to carrying products or produce with a higher unit value where the returns to transport costs may be correspondingly higher. Management control decisions are more tactical than strategic.
Operational control decisions: These involve making decisions about carrying out the " specific tasks set forth by strategic planners and management. Determining which units or individuals in the organisation will carry out the task, establishing criteria of completion and resource utilisation, evaluating outputs - all of these tasks involve decisions about operational control.
The focus here is on how the enterprises should respond to day-to-day changes in the business environment. In particular, this type of decision making focuses on adaptation of the marketing mix, e.g. how should the firm respond to an increase in the size of a competitor's sales force? should the product line be extended? should distributors who sell below a given sales volume be serviced through wholesalers rather than directly, and so on.
Within each of these levels, decision making can be classified as either structured or unstructured. Unstructured decisions are those in which the decision maker must provide insights into the problem definition. They are novel, important, and non-routine, and there is no well-understood procedure for making them. In contrast, structured decisions are repetitive, routine, and involve a definite procedure for handling them so that they do not have to be treated each time as if they were new.
Structured and unstructured problem solving occurs at all levels of management. In the past, most of the success in most information systems came in dealing with structured, operational, and management control decisions. However, in more recent times, exciting applications are occurring in the management and strategic planning areas, where problems are either semi-structured or are totally unstructured.
Making decisions is not a single event but a series of activities taking place over time. Suppose, for example, that the Operations Manager for the National Milling Corporation is faced with a decision as to whether to establish buying points in rural locations for the grain crop. It soon becomes apparent that the decisions are likely to be made over a period of time, have several influences, use many sources of information and have to go through several stages. It is worth considering the question of how, if at all, information systems could assist in making such a decision. To arrive at some answer, it is helpful to break down decision making into its component parts.
The literature has described 4 stages in decision making: intelligence, design, choice and implementation. That is, problems have to be perceived and understood; once perceived solutions must be designed; once solutions are designed, choices have to be made about a particular solution; finally, the solution has to be implemented.
Intelligence involves identifying the problems in the organisation: why and where they occur with what effects. This broad set of information gathering activities is required to inform managers how well the organisation is performing and where problems exist. Management information systems that deliver a wide variety of detailed information can be useful, especially if they are designed to report exceptions. For instance, consider a commercial organisation marketing a large number of different products and product variations. Management will want to know, at frequent intervals, whether sales targets are being achieved. Ideally, the information system will report only those products/product variations which are performing substantially above or below target.
Designing many possible solutions to the problems is the second phase of decision making. This phase may require more intelligence to decide if a particular solution is appropriate. Here, more carefully specified and directed information activities and capabilities focused on specific designs are required.
Choosing among alternative solutions is the third step in the decision making process. Here a manager needs an information system which can estimate the costs, opportunities and consequences of each alternative problem solution. The information system required at this stage is likely to be fairly complex, possibly also fairly large, because of the detailed analytic models required to calculate the outcomes of the various alternatives. Of course, human beings are used to making such calculations for themselves, but without the aid of a formal information system, we rely upon generalisation and/or intuition.
Implementing is the final stage in the decision making process. Here, managers can install a reporting system that delivers routine reports on the progress of a specific solution, some of the difficulties that arise, resource constraints, and possible remedial actions. Table 9.1 illustrates the stages in decision making and the general type of information required at each stage.
