1 Unit-2 Management Information Systems
Computer/MIS/ Unit-2

2 MIS – A concept: Management
Art of getting things done through and with the people in formally organized groups Managerial functions: Planning Organizing Staffing Directing Controlling Computer/MIS/ Unit-2

3 Planning Organizing Managerial functions:
Process of foreseeing the future What, when, who, how, where, why Setting goals and objectives Lay down policies, procedures, budgets, strategies, programmes and schedules, to achieve the plans Organizing Process of identifying the entire job Dividing the job into convenient subtasks Allocating subtasks to persons/groups Delegating authority, for effective operation and achievement of goals Computer/MIS/ Unit-2

4 Staffing Directing Managerial functions: Right person at the right job
Define job requirements – people perspective Select suitable person/s for the positions Training and development Job-orientation vs. person-orientation Directing Issuing commands – classical view Modern philosophy – Communication, Motivation, Leadership People have to be guided, motivated and led by the MANAGER Computer/MIS/ Unit-2

5 Decision-making is the essence of management
Controlling Controlling and planning – two sides of the same coin Ensures that activities are performed as per plans Fixing standards of work measurements Measurement of actual performance Taking corrective measures Decision-making is the essence of management Computer/MIS/ Unit-2

6 Information Processed data, presented in a form which assists decision-makers May contain an element of surprise, reduce uncertainty May provoke a manager to initiate action Data and Info – relative concepts Recency Producer-consumer relationship Often used interchangeably Computer/MIS/ Unit-2

7 New perspective of Information:
MIS = MI + S MIS must provide MI to managers for decision-making MI – quality info Timeliness Accuracy Completeness Adequacy Explicitness MI – a subset of the entire available info Computer/MIS/ Unit-2

8 System A set of interconnected elements to achieve a common objective
Elements are interrelated and interdependent Composed of sub-systems, which in turn may be made up of other subsystems The set of elements may be: Input(s), Process(es), or output(s) Info system converts data into information Computer/MIS/ Unit-2

9 A system cannot exist in vacuum
Cybernetic systems – self-regulating, self-monitoring (feedback and control elements attached) A system cannot exist in vacuum It exists and functions in an environment, separated by its boundary Several systems may share the same environment Some systems may be connected by a shared boundary Open system: interacts with its environment, exchanges inputs and outputs Closed systems: do not interact, or exchange any inputs or outputs with its environment Computer/MIS/ Unit-2

10 Definition of MIS MIS is a system consisting of people, machines, procedures, databases and data models as its elements. The system gathers data from internal and external sources of an organization; process it and supplies information to assist managers in the process of decision making. Computer/MIS/ Unit-2

11 MIS Functions Data Capturing Processing of Data Storage of Information
Retrieval of Information Dissemination of Information Computer/MIS/ Unit-2

12 MIS Characteristics: System approach Management oriented Need based
Takes Comprehensive view in the light of its objective Management oriented Top down approach followed Derived from the overall business objectives Need based Caters to info needs at different levels Exception based Exception based reporting principle Computer/MIS/ Unit-2

13 Futuristic Integrated Common data flows Long term basis
On the basis of projections Integrated Blends info from several operational areas Common data flows Should avoid data duplication and redundancy Long term basis Strive to be futuristic Divide and conquer Use partitioning into subsystems Central database Let subsystems access the master data Computer/MIS/ Unit-2

14 Interdisciplinary Nature:
Borrowed concepts from: Computer science Accounting Operations Research Management sciences Computer/MIS/ Unit-2

15 Levels of Managerial Decision Making
Computer/MIS/ Unit-2

16 Strategic Management The People Develop
Board of Directors, Chief Executive Officer, President, Top Executives Develop Organizational Goals, Strategies, Policies Long-term Planning Monitor – Strategic performance of the organization Direction Political Economic Competitive business environment Computer/MIS/ Unit-2

17 Tactical Management People Decisions Business Unit Managers
Vice-President to Middle-Manager Decisions short-medium range planning schedules budgets policies procedures resource allocation Computer/MIS/ Unit-2

18 Operational Management
People Middle-Managers to Supervisors Self-directed teams Decisions short-range planning production schedules day-to-day decisions use of resources enforce polices follow procedures Computer/MIS/ Unit-2

19 Decision Structure Structured (operational) Unstructured (strategic)
The procedures to follow when decision is needed can be specified in advance Unstructured (strategic) It is not possible to specify in advance most of the decision procedures to follow Semi-structured (tactical) Decision procedures can be pre-specified, but not enough to lead to the correct decision Computer/MIS/ Unit-2

20 Decision Support Systems
Management Information Systems Decision Support Systems Decision support provided Provide information about the performance of the organization Provide information and techniques to analyze specific problems Information form and frequency Periodic, exception, demand, and push reports and responses Interactive inquiries and responses Information format Prespecified, fixed format Ad hoc, flexible, and adaptable format Information processing methodology Information produced by extraction and manipulation of business data Information produced by analytical modeling of business data Computer/MIS/ Unit-2

21 Decision Support Trends
The emerging class of applications focuses on Personalized decision support Modeling Information retrieval Data warehousing What-if scenarios Reporting Computer/MIS/ Unit-2

22 Business Intelligence Applications
Computer/MIS/ Unit-2

23 Decision Support Systems
Decision support systems use the following to support the making of semi-structured business decisions Analytical models Specialized databases A decision-maker’s own insights and judgments An interactive, computer-based modeling process DSS systems are designed to be ad hoc, quick-response systems that are initiated and controlled by decision makers Decision support systems (DSS) are computer-based systems that provide managers and business professionals interactive information support for semi-structured and unstructured decisions. Unlike management information systems, DSS rely on model bases. Computer/MIS/ Unit-2

24 DSS Components Computer/MIS/ Unit-2

25 DSS Model Base Model Base Spreadsheet Examples
A software component that consists of models used in computational and analytical routines that mathematically express relations among variables Spreadsheet Examples Linear programming Multiple regression forecasting Capital budgeting present value Computer/MIS/ Unit-2

26 Applications of Statistics and Modeling
Supply Chain: simulate and optimize supply chain flows, reduce inventory, reduce stock-outs Pricing: identify the price that maximizes yield or profit Product and Service Quality: detect quality problems early in order to minimize them Research and Development: improve quality, efficacy, and safety of products and services Computer/MIS/ Unit-2

28 Decision Support Systems Analytical Models
A model base is a software component that consists of models used in computational and analytical routines that mathematically express relationships between variables. There are various types of DSS analytical model bases. These include: What-If Analysis. An end user makes changes to variables, or relationships among variables, and observes the resulting change in the value of other variables. Sensitivity Analysis. A special type of what-if analysis in which the value of only one variable is changed repeatedly, and the resulting changes on other variables are observed. Goal-Seeking Analysis. Instead of observing how changes in a variable affect other variables, goal-seeking analysis sets a target value for a variable, and then repeatedly changes other variables until the target value is achieved. Optimization analysis. A more complex goal-seeking model. Instead of setting a specific target value for a variable, the goal is to find the optimum value for one or more target variables, given certain constraints. Computer/MIS/ Unit-2

29 Decision Support System – Why?
Fast Computation Enhanced Productivity Data Transmission Better Decisions Competitive Edge Computer/MIS/ Unit-2

30 Characteristics & Capabilities of Decision Support System
Provide support for decision makers mainly in semi-structured & unstructured situation Provide support for various managerial levels Provide support to several interdependent and/or sequential decisions. Support all phases of decision making process: intelligence, design, choice & implementation Utilizes models for analyzing decision making situations Computer/MIS/ Unit-2

31 Characteristics & Capabilities of Decision Support System
DSS aims to support the decision makers not to replace them DSS attempts to improve the effectiveness of decision making (accuracy, timelines, Quality) DSS are flexible & so user can add, delete, combine , change or rearrange basic elements. Computer/MIS/ Unit-2

32 Information Resources Management (IRM)
„ It is an emerging discipline that helps managers assess and exploit their information assets for business development. „ It draws on the techniques of information science (libraries) and information systems (IT related). „ It an important foundation for knowledge management, in that deals systematically with explicit knowledge. Knowledge centres often play an important part in introducing IRM into an organization. Computer/MIS/ Unit-2

33 Key Activities for effective IRM
Identification „ - What information is there? How is it identified and coded? † Ownership „ - Who is responsible for different information entities and co-ordination? † Cost and Value „ - A basic model for making judgements on purchase and use † Development „ - Increasing its value or stimulating demand. † Exploitation „ - Proactive maximization of value for money Computer/MIS/ Unit-2

34 Benefits of implementing an IRM Strategy
Identifies gaps and duplication of information „ Clarifies roles and responsibilities of owners and users of information „ Provide costs saving in the procurement and handling of information „ Identifies cost/benefits of different information resources „ Actively supports management decision processes with quality information Computer/MIS/ Unit-2

35 IRM Information resource management has become a popular way to emphasize a major change in the management and mission of the information systems function in many organizations. In many organizations, IRM may be viewed as having five major dimensions: 1. Strategic Management - information technology must be managed to contribute to a firm=s strategic objectives and competitive advantages, not just for operational efficiency or decision making. 2. Operational Management - information technology and information systems can be managed by functional organizational structures and managerial techniques commonly used throughout other business units Computer/MIS/ Unit-2

36 IRM 3. Resource Management - data and information, hardware and software, telecommunications networks, and IS personnel are vital organizational resources that must be managed like other business assets. 4. Technology Management - all technologies that process, store, and communicate data and information throughout the enterprise should be managed as integrated systems of organizational resources. 5. Distributed Management - managing the use of information technology and information system resources in business units or workgroups is a key responsibility of their managers, no matter what their function or level in the organization.

37 End user Computing End-user computing refers to the everyday use of computers for both business and personal use. At every level, many workers interact with personal computers (PCs) to accomplish their work. Many people also have computers in their homes. However, when computers were first used in business, most people did not have computers on their desks, nor did they use com The development of end-user computing was due to several industry trends during the 1970s and 1980s: (1) the backlog of requests for new mainframe applications, (2) an increase in the number of knowledge workers who work primarily with information, (3) the availability of inexpensive microcomputers, (4) the availability of inexpensive productivity software, and (5) the development of user-friendly graphical user interfaces.puters themselves—at least not directly. Computer/MIS/ Unit-2

38 End users End users can be categorized according to skill level (novice, unskilled, semiskilled, or expert), environment (home or business), software used, frequency of use (occasional, frequent, or constant), features used (basic, intermediate, or advanced), or location (internal employee or external client). Computer/MIS/ Unit-2

39 Resources Resources that end users need to use a computer system include hardware, peripherals, hardware upgrades and maintenance, operating system and applications software, software upgrades, supplies, data and information, facilities, and technical support.These resources significantly affect the total cost of end-user computing to an individual or a company Computer/MIS/ Unit-2

40 Software- end user End users run a variety of software packages on their personal computers, including electronic mail and messaging, Web browsers, word processing, spreadsheets, database management, graphics, planning and scheduling, desktop publishing,Web page development, educational and entertainment software, as well as traditional mainframe applications Computer/MIS/ Unit-2

41 Computer/MIS/ Unit-2

42 End-user computing A primary goal of end-user computing is to make employees more productive in their jobs. However, productivity is not without costs, because end users can misuse their personal computers. Common problems include waste, mistakes, computer crime, piracy, invasion of privacy, loss of data, computer viruses, and health problems Computer/MIS/ Unit-2
