level of decision making in management information system

The solution is simple to find: even a technically mediocre solution may prove to be ‘effective’ (in the sense defined above) if it is implemented with enthusiasm and dedication. They are entrusted with responsibilities in decision-making. 11. 2. This often creates additional problems (which are often of a complex nature) because of shared power, bargaining activities and need for compromise present in most group decisions. That is, decisions are made within the context of, and influenced by, the objective or set of objectives defined by the decision maker. In fact, choosing the best alternative in terms of facilities, satisfactoriness and affordable consequences is the real crux (or the essence) of the decision-making process. There are two steps to this process: the first is to consider how the relevant environmental factors may change; the second is to assess the strategic implications of such changes for the firm. As managers “we will make different types of decisions under different circumstances. Evaluation of Alternatives and Selection of a Course of Action: The next step in the decision-making process is evaluating each of the alternatives generated in the previous step. Alvar Elbing has proposed the following five rules for evaluating alternatives: 1. Within the boundaries laid down by these factors his choices are rational-goal-oriented.”. When it comes to defining the criteria, organizational goals as well as the corporate culture should be taken into consideration. High-Quality, High-Velocity Decision-Making. A programme, for example, might be developed for the sole purpose of implementing a course of action for solving an organisational problem. Managers rarely consider all possible alternatives to the solution of a problem. Evaluate the outcome of your decision. In fact, managers often identify one or two alternatives very fairly and choose from among them. In order to make such an evaluation of the effectiveness of a possible decision, the following three conditions must be fulfilled: Firstly, there must exist a set of standards which act as yardstick against which to compare performance. Existing pay scales are used as guideline to fix the starting salary of a new factory guard or a new security officer. Since managers regularly have a series of decisions to make, organisations have to develop varying decision rules, programmes, policies, and procedures to use. Moreover, since there are always additional alternatives waiting to be discovered, the process of generating alternatives could conceivably go on forever. Their habits, or those of their peers, will help them decide quickly what to do about them. Finally, a major strength of group decision-making is the relative ease of implementing decisions that have been made. We will be reasonably confident that the supplier chosen will meet our expectations. In most situations managers will not have to worry about what to pay a new employee because most organisations have an established salary structure (or pay policy) for any position. This phenomenon can, of course, be prevented if the leader accepts ultimate responsibility for decision-making. The chapter also discusses information systems for making decisions at different levels of management – Decisions Support Systems (DSS), and TPS and MIS, … There are various types of decisions such as setting up a new area or adding or dropping a new product on the product line, or hiring additional sales persons to increase the market share for a particular product, or even dismissing a worker. Alternatively there may be prohibitive constraints. Most people think that an effective decision is one that optimism some factor such as profits, sales employee welfare, or market share. Identification of Resources and Constraints. In addition, we may make our own private decisions or may prefer a collective decision. General information which are impressionistic in nature about conditions and operations (such as the manager’s ‘feel’ for the situation). It is generally useful to design the process in such a way that both obvious, standard solutions and creative, informative solutions or alternatives are generated. Most often than not decision makers filter the information they receive, i.e., they pay more attention to some information than to other information. 1,000,000. Before uploading and sharing your knowledge on this site, please read the following pages: 1. The fact that someone must make a decision implies that there is a problem to be solved. Effective managers usually rely on policy as a time saver. 116 Management Information Systems ... Each type of information system serves a particular level of decision-making: operational, tactical, and strategic. Group Decision Making—Use of Committees: The steps in the decision-making process descried so far focused primarily on the individual decision maker. Every decision making process produces a final choice
It can be an action or an opinion. There are several ways of doing it. Secondly, more often than not group decisions are comprehensive decisions resulting from differing points of view of individual members, rather than the selection of the most appropriate (or the best possible) choice for solving the problem. Unexpected cost increases a less-than-perfect ‘fit’ with existing organisa­tional subsystems, unpredicted effects on cash-flow or operating expenses, or any number of other situations could develop after the implementation process has begun”. The central feature of the principle of bounded rationality is Simon’s contention that the so-called ‘administrative man’ does not follow an exhaustive process of evaluation of the options open to find a course of action that is satisfactory or good enough. Managerial decision-making is also concerned with regulating and altering the relationship between the organisation and its external (immediate) environment. Fig. In the process of decision-making, we may use many tools, techniques, and perceptions. Its purpose is “Planning involves the most significant and far-reaching decisions a manager can make. Prohibited Content 3. For example, the final criterion used to select a plant site might be its proximity to the manager’s home town. Do not work well in real-time systems however, it may work in a dynamic system being in equilibrium. A solution has to be acceptable to those affected by it and to those who must implement it. The ability to make good decisions is the key to successful managerial performance. It is, therefore, quite obvious that the key element in decision-mak­ing under a state of risk is accurately determining the probabilities associated with each alternative. Limited information processing - A person can manage only a limited amount of information. Decision to raise a Purchase Order
Most non-programmed decisions involve innumerable variables and it is neither possible nor feasible, with limited knowledge and resources, to examine them all. Thus the second step in the decision process is to establish objectives or to take account of those that have been previously defined. Once you go through from Step 1 to Step 5, this step is easy. Fig. Decision making is the developing concepts leading to the selection of a course of action among variations. Thirdly, managers’ acceptance of solution is increased through their participation. Identification of Resources and Constraints: Just as a business manager does not operate in isolation, problem solving does not occur in vacuum. To optimize the tolerance of manufactured parts. This definition has three different but interrelated implications. Here, we treat decision-making as essentially an individ­ual process, but a process that occurs in an organisa­tional context. The second factor is the ability of the decision-maker to differentiate accurately among alterna­tives determining the amount of time that he should devote in developing alternatives and cannot, in advance, tell the difference between two alternatives and cannot rank them accurately according to this likely effectiveness. Such a response refers to the reaction of the organisation and its individual members to an alternative that has been chosen. In this article we shall discuss how managers can best go about reaching good (rational) decisions. However, since most managerial problems are intimately concerned with the human element in the organisation, implementation of solution is no doubt a complex exercise. In fact, Simon’s view of the modern manager is different from the views of other writers on management. Execute your plan by yourself or with the help of subordinates. Business managers have to make various types of decisions. Another problem to consider when implementing decisions is people’s resistance to change. This explains why various organisations often build up inventories and forecasting of short-term changes in demand and supply conditions are integral parts of managerial decision-making. 1. As implementation of solution proceeds, organisation members should be able to modify the solution based on what they learn during implementation. Otherwise it may cease to exist. There will not be any rules to follow. The practice in America is just the opposite. Decision-making variable not clearly defined. When deciding to enter a new market, we will be much less certain about the success of our decision. Management information systems (MIS) serve the management level of the organisation, providing managers with reports and often online access to the organisation's current performance and historical 37 Kenneth Laudon and Jane Laudon: Essentials of Management Information Systems, 9th edition, 2011, pg. 2. However, decision-making is usually most closely associated with the planning function, inasmuch as it is an important tool for most planning activities. 8. 2 lakhs. Recognising and Defining the Decision Situation. A problem of an organization will have many stakeholders. When an implemented alternative fails to work, the manager has to respond quickly. There are different information requirements at different levels of responsibility in the organization that affect the types of decisions made at each level. These decision-makings are more complex and real-time. Content Guidelines 2. Such decisions obviously involve long-term planning and policy formulation. Type of information required. The normative model of decision-making considers constraints that may arise in making decisions, such as time, complexity, uncertainty, and inadequacy of resources. But unless some specific provision is made for modification of the chosen solution, the chosen alternative may be left untouched and implemented without any thought of possible modification — even in those situations where minor adjustments would produce better solutions. How much time and money should be developing alternatives: Time and money are the important resources at the disposal of the decision-maker. When plans go wrong or out of track, managers have to decide what to do to correct the deviation. “Programmed decisions are those that are made in accordance with some habit, rule or procedure. A related point may be noted in the context. Operational Research (OR) includes a wide range of problem-solving techniques involving various advanced analytical models and methods applied. However, 1978 Nobel Laureate H. A. Simon has made extensive study of managerial behaviour and on the basis of his investigation arrived at the conclusion that modern managers do not always attempt to maximize profits. 3. A more realistic decision-making situ­ation is a state of risk. Non-programmed decisions occur in unusual and non-addressed situations, so − 1. In short, while strategy should not be conceived as exclusively concerned with the relation between the enterprise and its environment, assessing the effects of possible future changes in the environment is an essential task in strategy formulation. However, most important and strategic decisions in modern organisations are taken under conditions of uncertainty. With changes in society and in its economic framework, an organisation must adapt itself to such changes. Managers know how important decision-making is from the organisational point of view. It therefore lies at the heart of business cost-benefit analysis. The third level represents management information systems to process information by managers. It may even mean selecting the best method for going out of business or terminating a contract. At the same time the amount of time top management must devote to the process is considerably reduced. Common constraints include legal restrictions, moral and ethical norms, authority constraints, or constraints imposed by the power and authority of the manager, available technology, economic considerations and unofficial social norms. Due to shortage of traditional sources of energy the passenger car industry of the U.S. was reeling under recession from 1973 onwards. Discuss the information system needed for different types of decision making of management? Executives need high-level data with the ability to drill down as necessary. 8.5 illustrates the steps in the decision-making process. Disclaimer 8. Programmed and Non-Programmed Decisions: Nobel Laureate H. A. Simon has distinguished between two types of decisions, viz., programmed and non-programmed moved decisions. Information plays a crucial role in every stage of the decision-making process. The key to effective decision-mak­ing under uncertainty is to acquire as much relevant information as possible and to approach the situation from a logical and rational perspective. There is no exception about that. Fourthly, managers can communicate decisions and their rationale to their own work groups. According to this model, decision-making is characterized by −. Such boundaries include limits to any manager’s knowledge of all alternatives as well as such elements as prices, costs and technology that cannot be changed by the decision maker.”. This is an important step because situation definition plays a major role in subsequent steps. In fact, different risks are involved for different individuals and groups in the organisation. Identifying the important criteria for the process and the result. Heuristic programming refers to a branch of artificial intelligence. Recognising and Defining the Decision Situation: The first step in making a decision is recognising that a decision is necessary — there must be some stimulus to initiate the process. and Other Details. Decisions concerning such activities are basically technical in nature. Finally, it is absolutely essential to develop a data analysis strategy. Intuition, judgement and experience always play a very important role in decision-making under uncertain conditions. Therefore, corporate decision-making is the most critical process in any organization. 5. In the case of the manager who must choose a site for a new plant, some of the minimum requirements for the site may be that it must be within 500 meters of a railroad spur and within 2 kilometers of a major highway, be located in a community of at least 40,000 people, and cost less than Rs. These conditions are repre­sented in Fig. Sensitivity analysis also helps in some other situations, like −. decision making. The decision maker has to develop a brief explicit list of the major resources which enables the decision maker to make the best possible utilization of the organisation’s resources. The decisions may be such as where to invest money, where to set up a new plant or warehouse, how to deal with to invest money, where to set up a new plant or warehouse, how to deal with an employee who is invariably late, or what subject should be brought into focus in the next departmental meeting. There are two types of decisions - programmed and non-programmed decisions. Information, as required at different levels of manage­ment can be classified as operational, tactical and strategic. It plays the most important role in the planning process. In the words of Boone and Koontz: “Institutional decisions involve long-term planning and policy formulation with the aim of assuring the organisa­tion’s survival as a productive part of the economy and society.” The implication is clear: if an organisation is to thrive in the long run as a viable organisation, it must occupy a useful, productive place in the economy and society as a whole. Therefore, Simon argues that instead of attempting to maximise, the modern manager satisfies. It consists of programs that are self-learning in nature. 1. Sensitivity analysis is a technique used for distributing the uncertainty in the output of a mathematical model or a system to different sources of uncertainty in its inputs. The inference is that rather than optimizing in the strict sense of proceeding to a maximum they consider all the constraints bearing on the decision situation and choose a course of action that is satisfactory to them (i.e., good enough under the present circumstances). If the organisation is to survive and grow in the long nm it must be ready to adapt and evolve in response to diverse environmental changes. The ability to make effective decisions that are rational, informed, and collaborative can greatly reduce opportunity costs while building a strong organizational focus. Decisions are no doubt made by managers but these are carried out by other members of the organisation. As the final step in the decision-making process, managers should be very sure to evaluate the effectiveness of their decision. When deciding what salary to pay a new employee, we will usually be able to be less cautious. If the firm consistently achieves a given objective, then the objective might be reviewed or changed to prevent under-achievement. Levels of Decision making. As Stoner puts it: “It does not take a wise manager to reach a decision when there are no other possible choices. This gap reveals the difference between the predicted or expected level of performance and the actual level. In other words, managers hardly enjoy any discretion in matters involving programmed decisions set managers, decide what to do. Copyright 10. Who are the affected parties of the problem? Empirical evidence available so far suggests that decision made by groups are more accurate than those made by individuals. Further, he argues that “the individual can be rational in terms of the organisation’s goals only to the extent that he is able to pursue a particular course of action, he has a correct conception of the goal of the action, and he is correctly informed about the conditions surrounding his choice. Decision Room − Participants are located at one place, i.e. A few examples of such decisions may now be given. Managers have to vary their approach to decision-making, depending on the particular situation involved. In other words, they act as obstacles to be overcome by the decision makers — when an organisation fails to achieve its goals, a performance gap is said to exist. For the process of information gathering, tools such as 'Check Sheets' can be effectively used. Satisfying - A person may choose a solution that is just "good enough". Alternatively, the manager might recognise that the situation was not correctly defined to start with and begin the decision-making process all over again. A solution should have substantial quality so that it can meet organisational goals. Usually each alternative has to be assessed to determine its feasibility, its satisfactoriness, and its consequences. This is more so in those situations involving complex problems where no one member is a specialist in the problem area. According to Simon modern managers act within bounded rationality. Simon does not attempt to prove that managers do not attempt to make effective decisions. the decision room. That is, they should make sure that the alternatives chosen in step 5 and implemented in step 6 have accomplished the desired result. In short, the concept of bounded rationality refers to “boundaries or limits that exist in any problem situation that necessarily restrict the manager’s picture of the world. It’s all about making better decisions and making them fast. The six-step decision making process increases the likelihood that a high quality, accepted decision will result (Certo, 1997). In addition, the selection of the best alternative is an informed decision since you have already followed a methodology to derive and select the best alternative. This should be of critical concern to the manager or decision maker. Similarly, the amount of information we will have available to us when making a decision will vary. Decision makers are unable or unwilling, or both, to fully anticipate the consequences of each available alternative. Essentially, Simon suggests that people may try to be rational decision makers but that their rationality has limits. In short, technical decisions are concerned with the process through which inputs such as people, information or products are converted into outputs by the organisation. Every organisation has written or unwritten policies that simplify decision-­making in a particular situation by limiting or excluding alternatives.”. The satisfying concept suggests that she or he will select this site even though further searching might reveal a better one. American managers often criticise the group (or committee approach) on two major grounds. In such a situation a programmed decision — that is a decision to advertise the product in accordance with budget guidelines — may prove to be wrong. Managers are faced with a wide range of decisions on any given day. All successful organi­sations have made various effective decisions under uncertainty. Moreover, since time management is a very real part of managerial work manages devote much of their time for problem solving and not for problem formulation. When making a decision managers have a purpose. In this step, the problem is thoroughly analyzed. These decisions have been taken several times. Report a Violation 11. In addition, there can be dozens of factors involved and affected by the problem. Account Disable 12. 7. In this step, the baseline criteria for judging the alternatives should be set up. As Boone and Kurtz have argued: “if judgement was suspended during the creative generation of alternatives in the previous step, most of the alternatives generated would fall into the infusible category. 371. It is also necessary to consider the various types of risks associated with each alternative. This step lies at the heart of the decision-making process. On the contrary, effectiveness is a measure of the extent to which an alternative meets the stated objective (regardless of the costs involved). The chief approach to formulating the data collection process is the design of management information systems. Decision-Making at Different Levels in the Organisation: A study of the decision-making in different organisations reveals that the three types of decisions listed above are not evenly spread throughout the organisa­tion. Typically, MIS are oriented almost exclusively to internal, not environmental or external, events. There is no denying the fact that programmed decisions limit the freedom of managers to a considerable extent.
