1. INTRODUCTION The objective of this paper is to have a critical assessment of what are Decision Support Systems, particularly in the Organizational context, historical genesis of these systems and the latest trends in this sub field of MIS. Along with the above mentioned objectives, we have tried to explore, by way of examples, the relevance and importance of DSS in large, complicated decision making settings. We also will attempt to visualize, how DSS’s may evolve 20 years from now in a vastly connected world and which type of problems it could help solve efficiently 2. DECISION MAKING- CONCEPTUAL UNDERSTANDING Decision-making, in effect is a cognitive process in which human beings select the best course of action from various multiple choices/alternatives. Since it is a very tacit and subtle process , making is invisible, it is called a psychological construct1. The decision making leads to final action. Decision-making acts as an important part of the job in many professions wherein important and critical decisions are made by the specialists who possess requisite expertise in that given area. The areas can be related to as diverse as politics(as in Mr Obama, the US President making a decision to deploy forces in a war torn country), or scientific discovery or may be a typical business decision (Apple launching a new product next summer).As there are different considerations in decision-making, the decision support systems belong to a multidisciplinary environment which includes database research, artificial intelligence, human-computer interaction, simulation methods, and software engineering. In short , DSS are support systems which are expected to cut across huge data points , perhaps contradictory and give a reasonable... ... middle of paper ... ...nces of the group decision-making process. With the development of Local Area Networks (LAN), the GDSS concept evolved into computer supported cooperative work (CSCW). In this way, researchers recognized that decision makers not only come together to make decisions (as supported in the decision war room context), but also often work together over time on projects and problems. DSS research and practice have evolved along with information technology. The concept of DSSs to support concentrated human problem solving was not possible until humans could interact with computers. IT could not support groups until networking infrastructure was readily available. Knowledge-based DSSs were not feasible until AI and expert systems concepts were developed. As information technology seems to be expanding exponentially, the opportunities for DSSs will become ever more extensive.
The four simple steps taught me how. Making decisions will be significantly easier if I utilize the DDM. I know that the D.A.R.E. Decision Making Model will be beneficial to me even as I grow older and I am grateful that I have learned such a useful tool to implement in my life. D.A.R.E. has taught me useful techniques, tips, and strategies that will undoubtedly impact my actions in the future.
Asemi observe that Management Information System (MIS) is one of the information systems that is computer based. Besides, Asemi defines MIS as “an organizational method of providing past, present and project information related to internal operations and external intelligences. It supports the planning, control and operation functions of an organization by furnishing uniform information in the proper time frame to assist the decision makers,” (2011). The aim of MIS is to satisfy the general information need of the entire manager in an organization. Before the advent of computers, the process of decision-making was one that was full of built-in advantages and ad hoc methods. Computers technologies have changed the landscape of the decision-making process completely by making the process less demanding and easy to undertake. The reason for this situation is that information technology has made access to information more automated, efficient, effective, timely, and less ambiguous. Consequently, the ordinary t...
In the business world today, technology is becoming an essential staple. Every big business relies on it one way or another. More importantly than just technology itself, the use of management information systems is what guides a company in terms of catering to its customers and knowing what moves to make next. Management information systems (MIS) can be defined is the study of people, technology, and organizations (What is MIS?). However, that is a very general definition because there is a lot more that comes out of the use of these MIS systems.
DSS facilitate enhanced interpersonal communication among those responsible for decision making. Communication-Driven Decision Support Systems and Group Decision Support Systems lead in more lubricated communication process and sharing of information. Moreover, Model-Based Decision Support systems offer a platform for sharing certain facts and suppositions regarding the decision making process. At Amazon.com Data-driven Decision make certain information about the company available to managers to make it easy for them to make decisions that ens...
Presently there are a considerable amount of experimental facts that individual instinctive opinion and assessment can be far from most favorable, and it gets worse even more with complication and pressure.
Thinking critically and making decisions are important parts of today’s business environment. It is important to understand how the decision making process works and the steps involved. The nine steps of the decision making process are: identifying the problem, defining criteria, setting goals and objectives, evaluating the effect of the problem, identifying the causes of the problem, framing alternatives, evaluating impacts of the alternatives, making the decision, implementing the decision, and measuring the impacts. (Decision, 2007.) By using various methods and tools to assist in making important business decisions an individual can ensure the decisions they make will be as successful as possible. In this paper it will be examined how the decision making process can be followed using various tools and techniques to make successful business decisions by using these same tools and techniques during a thinking critically business scenario. The paper will also discuss how different tools and techniques could have been used to make different, yet still successful decisions.
A good example of me using the D.A.R.E decision making model is this. There is a big test tomorrow and you need a good passing grade, so you need to study for the test tomorrow, but your friend is having a party and you really want to let out that stress and enjoy yourself. Now is the perfect time for the D.A.R.E decision making model. First i need to define my problem. Big test is tomorrow and i need to study, but my friend is having a party.
Group Decision Support System, or GDSS, is “an interactive, computer- based system that helps a team of decision-makers solve problems and make choices. GDSS are targeted to supporting groups in analyzing problem situations and in performing group decision-making tasks” (Power 2005). Group Decision Support Systems are designed to help groups in meetings reach a consensus. “The fundamental goal of a GDSS is to support collaborative work activities such as idea creation, message exchange, project planning, document preparation, mutual product creation
There are expert systems that can solve complex problems that humans train their whole lives for. In 1997, IBM's Deep Blue defeated the world champion in a game of chess (Karlgaard, p43). Expert systems design buildings, configure airplanes, and diagnose breathing problems. NASA's Deep Space One probe left with software that lets the probe diagnose problems and fix itself (Lyons).
Decision making, as taken from the Wikipedia (2006) encyclopedia, is defined as "the cognitive process leading to the selection of a course of action among alternatives. Every decision making process produces a final choice called a decision. It can be an action or an opinion. It begins when we need to do something but we do not know what. Therefore, decision-making is a reasoning process which can be rational or irrational, and can be based on explicit assumptions or tacit assumptions." (para.1). Decisions made by using a decision-making model typically result in better decisions. Decisions resulting from the model tend to be more consistent since the same steps are followed each time. Increased thoroughness of decision options considered is another benefit in using a decision-making model, as numerous factors are taken into account.
Define the three primary types of decision-making systems, and explain how a customer of Actionly might use them to find business intelligence.
The journey of my decision analysis learning process has been a roller coaster ride. While I enjoyed reading, understanding and learning about the various methodology and aspects of decision analysis, I also find myself stressed, frustrated and ready to give up. For me, the concept about what is decision analysis, the utility of decision analysis, and the topics on decision bias, ethics, complexity and controversy of decision analysis make sense to me as I understood what they are and how they can impact a decision making process. Quantitatively, while I enjoy experimenting and learning the R, Rattle and Excel Decision Tree Plan, statistically, I am frustrated as I am unable to come up with the correct answers when it comes to the quantitative models and calculations such as the probability matrices, binomials, conditional probability, and Markov modeling. Learning the functionalities and seeing an outcome from the R software and knowing what an excel can do to a set of data is intriguing yet exciting to me,
Humans are constantly making decisions during their daily life. According to Huffington Post, an average person makes around 35,000 decisions per day. From choosing which shirt to wear to important life decisions that have long-lasting effects, the decision-making process is very complex. There are mainly two types of decision-making methods. The first method is using intuition, which is taking a decision with one’s “gut” feeling or what it seems to be right without thinking about it logically. The second way of taking a decision is through reason, which carefully analyzing all the data and using logic to conclude to a decision, which is the go-to method when taking important lifelong decisions. Different areas of the brain are responsible
This refers to the making of decisions using general rules of thumb or informed guesses without completely searching all the available alternatives or possibilities. This attribute of intelligent behaviour, whilst natural to humans, is difficult to achieve in machines. Given the right programs, a computer system can obtain good results/solutions t...
Making decisions is an important part of our everyday life. Decisions define actions and lead to the achievement of goals. However, these depend on the effectiveness of the decision-making process. An effective decision is free from biases, uncertainties, and is deeply dependent on information and critical thinking. Poor decisions lead to the inability to achieve set objectives and could lead to losses, if finance is a factor. Therefore, it is important to contemplate about quality and ways to achieve it in decision-making, which is the focus of this paper. The purpose is to look into the needs of decision-making, including what one should do and what one should not do.
