  • By: Prof. Riyanka Dwivedi Information systems in Organizations
  • Slide 2
  • Types of management systems : The main purpose of Information systems is to assist the management in decision making. The various processes in decision making requires information in various forms. Basically information is provided by the systems to the management at various levels like strategic level information, tactical level information and operational level information. The nature of information at the operational level is highly structured. The nature of information at the top level strategic is highly unstructured. Similarly the volume of information processed is very high at the bottom level and less at the top level. Management activities at different levels can be divided depending upon the nature of management function like marketing function, financial function, personnel function etc.
  • Slide 3
  • Slide 4
  • Transaction processing system (TPS) TPS are mainly observed at the bottom level of the management. Plenty of operational activities at the bottom level results in one or more transactions. Every transaction may be considered to generate information. The information generated can be highly structured. A structured information is easy to process further. Examples payroll system, transport ticket reservation system, purchase order entry system, marks tabulation system etc. Output of such systems may be of printed type or display type on the monitor of the computer. TPS may further be classified as online systems or batch systems. In online systems there is direct interaction of the operator and the TPS system. In batch systems activities of the same type are batched into groups and then processed. Example of online systems enquiry, checking availability of tickets etc. example of batch systems entering parcel details belonging to one destination, process student marks of one subject etc.
  • Slide 5
  • Transaction Processing Systems Most of an organizations daily activities are recorded and processed by its transaction processing system (TPS), which receives input data and converts them into output informationintended for various users. Input data are called transactionsevents that affect a business. A financial transaction is an economic event: it affects the firms assets, is reflected in its accounting statements, and is measured in monetary terms. Sales of goods to customers, purchases of inventory from suppliers, and salaries paid to employees are all financial transactions. Everything else is a nonfinancial transaction. The marketing department, for example, might add some demographic data to its customer database. The information would be processed by the firms TPS, but it wouldnt be a financial transaction.

  • MIS 175 Spring 2002 Chapter 10 7 Executive Information Systems What information does a chief executive of board member require?
  • Slide 8
  • Executive information systems (EIS) Executive information system may be considered to be useful at any level of management, specially at the middle level and bottom level. It mainly revolves around the day to day activities of management but not in strategic decisions. example where EIS is can be used assigning responsibilities to subordinates, analyzing the data generated out of a management process, documenting the reports generated, plotting trends, sales forecast etc. It provides information to the executives to manage their functions.
  • Slide 9
  • Executive Information Systems They set performance targets, determine whether theyre being met, and routinely scan the external environment for opportunities and threats. To accomplish these tasks, they need relevant, timely, easily understood information. Often, they can get it through an executive information system (EIS), which provides ready access to strategic information thats customized to their needs and presented in a convenient format. Using an EIS, for example, a gaming-company executive might simply touch a screen to view key summary information that highlights in graphical form a critical area of corporate performance, such as revenue trends. After scanning this summary, our executive can drill down to retrieve more detailed informationfor example, revenue trends by resort or revenue trends from various types of activities, such as gaming, hotel, retail, restaurant, or entertainment operations.

  • DSS
  • Slide 12
  • Decision support systems (DSS) In management many a times problems arise out of situations for which simple solution may not be possible. To solve such problems complex theories may have to be used. The models that would be required to solve such problems may have to be identified. DSS requires a lot of managerial abilities and managers judgment. Manager may sometimes find it difficult to solve such problems. Eg in a sales problems if there are multiple decision variables modeled as a simple linear problem but having multiple optima, it becomes difficult to take a decision. Since any of the multiple optima would give optimum results. But the strategy to select the one most suitable under conditions prevailing in the market, requires skills beyond the model. A system which consists of database pertaining to decision making based on certain rules is known as decision support system. It is a flexible system which can be customized to suit the organization needs. It can work in the interactive mode in order to enable managers to take quick decisions. DSS is a consistent decision making system. It can be used to generate reports of various level management activity. It is capable of performing mathematical calculations and logical calculation depending upon the model adopted to solve the problem.

  • GDSS Time/Place Environment Same-Time Same-Place (Most widely used GDSS- computers with projectors, voting tools) Same-Time Different-Place (team room, tools, audio conferencing, screen sharing, chat) Different-Time Same-Place (audio/video conferencing, document sharing) Different-Time Different-Place (voice mail, email, bulletin boards)
  • Slide 14
  • Advantages of GDSS Anonymity drive out fear leading to better decisions from a diverse hierarchy of decision makers Parallel Communication eliminate monopolizing providing increased participation, better decisions Automated record keeping no need to take notes, theyre automatically recorded Ability for virtual meetings only need hardware, software and people connected Portability - Can be set up to be portable laptop Global Potential - People can be connected across the world No need for a computer guru although some basic experience is a must
  • Slide 15
  • Disadvantages of GDSS Cost infrastructure costs to provide the hardware and software/room/network connectivity can be very expensive Security especially true when companies rent the facilities for GDSS; also, the facilitator may be a lower-level employee who may leak information to peers Technical Failure power loss, loss of connectivity, relies heavily on bandwidth and LAN/WAN infrastructure properly setup system should minimize this risk Keyboarding Skills reduced participation may result due to frustration Training learning curve is present for users, varies by situation Perception of messages lack of verbal communication could lead to misinterpretation
  • Slide 16
  • Typical GDSS Process 1) Group Leader (and Facilitator?) select software, develop agenda 2) Participants meet (in decision room/Internet) and are given a task. 3) Participants generate ideas brainstorm anonymously 4) Facilitator organize ideas into categories (different for user-driven software) 5) Discussion and prioritization may involve ranking by some criteria and/or rating to the facilitators scale 6) Repeat Steps 3, 4, 5 as necessary 7) Reach decision 8) Recommend providing feedback on decision and results to all involved
  • Slide 17
  • Future Implications of GDSS GDSS may play a large role in the future of the virtual companies GDSS can help the virtual companies do business in the global business environment GDSS can help promote a culturally diverse work environment Telework seems to make a lot of sense using GDSS
  • Slide 18
  • Choosing The Right GDSS Consider the following; Decision Task Type Group Size Location of members of the group

  • Management Information System Management information system (MIS) is one of the major computer based information systems. Its purpose is to meet the general information need of all the managers in the firm or in some organizational subunit of the firm. Management information system (MIS) can be described as "an organizational method of providing past, present and projected information related to internal operations and external intelligence. 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. The information is made is available in form of periodic reports, special reports and output of mathematical simulations. All managers use the information output as they make decisions to solve the firms problems.

  • Expert Systems Expert systems (ES) are programs that mimic the judgment of experts by following sets of rules that experts would follow. Theyre useful in such diverse areas as medical diagnosis, portfolio management, and credit assessment. For example, youve called the customer-service department of your credit-card company because you want to increase your credit line. Dont expect to talk to some financial expert whos authorized to say yes or no. Youll be talking to a service representative with no financial expertise whatsoever. He or she will, however, have access to an ES, which will give you an answer in a few seconds. How does it work? The ES will prompt the representative to ask you certain questions about your salary and living expenses. It will also check internal corporate data to analyze your purchases and payment behavior, and, based on the results, it will determine whether you get an increase and, if so, how much.

  • 2-37 Types (Categorization) of Knowledge Shallow (readily recalled) and deep (acquired through years of experience) Explicit (already codified) and tacit (embedded in the mind) Procedural (repetitive, stepwise) versus Episodical (grouped by episodes) chunks Knowledge exist in chunks
  • Slide 38
  • Chapter 3: Knowledge Management Systems Life Cycle Knowledge Explicit knowledge Objective, rational, technical Policies, goals, strategies, papers, reports Codified Leaky knowledge Tacit knowledge Subjective, cognitive, experiential learning Highly personalized Difficult to formalize Sticky knowledge
  • Slide 39
  • Chapter 3: Knowledge Management Systems Life Cycle Why Knowledge Management? Organizations are realizing how important it is to "know what they know" and be able to make maximum use of the knowledge. Preventing reinvent the wheel many times.
  • Slide 40
  • Chapter 3: Knowledge Management Systems Life Cycle Why Knowledge Management? Thus, organizations need to know: what their knowledge assets are; how to manage and make use of these assets to get maximum return. KM can improve organization efficiency by providing framework, tools and techniques to reuse captured intellectual assets.
  • Slide 41
  • Chapter 3: Knowledge Management Systems Life Cycle Why Knowledge Management? We have four people in Boston who know how to solve this problem. How can we get them to help our team in Korea? "People are leaving the company with a lifetime's experience. How can we capture and re-use that?" "We had a team that did a successful proposal for aerospace five years ago. Why did they make the decisions they did? How did they deal with the customer? What made the team tick?"
  • Slide 42
  • Chapter 3: Knowledge Management Systems Life Cycle Why Knowledge Management? "How do we start learning from our experiences and help our people stop repeating others' mistakes?" "We're involved in an exciting project with four other companies. How can we all learn how these virtual teams tick?" "Needs change often these days and we're always bringing new people into projects. How can we get them up to speed and contributing quickly?"
