Management Information System

Prof. Arathi S. Purohit

Basic Terminologies Data : Unstructured Raw Facts, Observations

or unevaluated messages. Information : Finished Product Database : Finished Product laid in a

systematic format. File : Logical Existence / name given Document : Textual Record

Stages in converting Data to Information

Capturing Verifying Classifying Arranging / Sorting Summarizing Calculating Storing Retrieving Reproducing Communication

Classification of Information Action Information : Induces action Non – Action Information : Communicates the

status Recurring : Regular Information Non – Recurring : Non repetitive Internal Information External Information

Types of Information Strategic Level

For strategic decision making one needs strategic information. It needs more futuristic inputs.

Tactical Level Tactical information used for medium and short

term planning by middle level management. Operational Level

It covers current happenings, information about specific product or task.

Introduction to MIS

An MIS provides managers with information and support for effective decision making, and provides feedback on daily operations.MIS is a system, which makes available the Right Information to the Right Person at the Right place at the Right Time in the Right Form and at Right Cost.

Purpose & Scope

The Purpose and Scope of MIS can be defined as “The combination of human and computer based resources that results in the collection, storage, retrieval, communication and use of data for the purpose of efficient management of operations and for business planning”.

Expectations from MIS Handling of Corpus data Confirmation of validity of data Complex processing through Multi

Dimensional analysis. Quick Retrieval Mass Storage Dynamic Timely Communication

MIS Reports Scheduled reportsProduced periodically, or on a schedule (daily, weekly, monthly) Key-indicator reportSummarizes the previous day’s critical activitiesTypically available at the beginning of each day Demand reportGives certain information at a manager’s request Exception reportAutomatically produced when a situation is unusual or requiresmanagement action Drill Down ReportsProvide detailed data about a situation.

Information as a Strategic Resource

Achieving strategic competitiveness in the present competitive environment could be enhanced through capturing data, processing the same, analyzing & transforming into useable knowledge.

Contemporary Approaches to MIS

Technical Approach – Based on Operation Research techniques

Behavioral Approach – Based on user requirement/friendliness

Socio – Technical Approach - Combination

Use of Information in Competitive Advantage

Due to globalization business environment have become highly competitive and information - based. ”Competitive Advantage is about changing the balance of power between a firm and its competitors in the industry, in the firm’s favor”.

Case Study: IS in RestaurantCase Study: IS in SystemX

Porter – Miller IT affecting competition

Changes the Industry Structure Produces new business Creates competitive advantage by giving

companies new ways to out – perform their rivals.

Changes the Industry Structure

Bargaining power of customers Bargaining power of suppliers Threat from new entrants in the firm’s market Threat from substitute products or services Positioning of traditional industry competitors

Produces new business Information derived from the surveys and the

analysis of the same may lead to birth of a new business in the existing one. Thus information confers competitive advantage to the firm as it can offer a bundle of goods / services.

Vroom-Jago Do you want High quality solution or best fit

solution? Is information gathered sufficient to take your

own decisions? Do you have structured problems? Do the members agreement towards the

towards is mandatory to accomplish a task? Will your group accept your decision? Chances of Disagreement from the group Goal Congruence (Mgr & Group)

Six-Step Model Define the problem Identify decision criteria Weigh the criteria Generate alternatives Rate each alternative Compute the ultimate option

Decision Analysis What If Analysis Sensitivity Analysis Goal Seeking Analysis – Goal Seek Goal Achieving Analysis - Scenarios

Decision Making Tools Decision Tree Decision Rule Decision Table Payoff Matrix Queuing Models

Decision Tree Decision Node – Initial Decision Point Chance Node – Options generated from

Decision Points

Decision Rule

List out all available options

Decision Tables

Tables may include both qualitative & quantitative bases for decisions based on the decision rules.

Payoff Matrix

Is a quantitative technique. It identifies the degree of likelihood of the occurrence of an event.EV – Expected value derived from possible consequences.

EV= prob (possibility1) + prob(possibility2)

Queuing Models Queue – Is a line of waiting customers who

require service from one or more service providers.

Queuing System – Waiting + Customers + Service Providers

Types of Queues Single – Channel, Single – Phase (Clinic) Single – Channel, Multiphase (Dual window) Multi – Channel, Single – Phase (Bank) Multi – Channel, Multiphase (Registration

Process) Parallel Single – Phase (Super Markets) Customer Discrimination (Insurance Co.) Converging Arrivals (Traffic Management)

Data Warehouse Every organization generates corpus data

from their day-to-day operations. Such data is considered to be the most powerful asset of the company.

The data collected in this way needs to be only in “update only” format.

For this activity the organization would require high end databases.

Data Warehouse

Data Warehousing is a new technology that provides the users the tools to store the summarized information from multiple, assorted databases in a single repository.A Data Warehouse is a Subject-Oriented, Integrated, Time-Varying, Non-Volatile collection of data.

Data Warehouse Structure

Data Warehouse Structure Data Marts are usually smaller chunks

extracted from Data Warehouse and focus on a particular subject or department.

Data Farm is a location all the data storing servers and other computer systems are placed.

Components/Elements of Data Warehouse

The major components of a Data Warehouse are:Source of Data Warehouse: (Transactional or Operational Database) from which the data warehouse is populated.Processes involved in creating a data warehouse:1.A process to extract data from the database, and bring it to data warehouse.

Components/Elements of Data Warehouse

2. A process to cleanse the data, to ensure its quality for decision making.3. A process to load the cleansed data into the data warehouse database.4. A process to create any desired summaries of the data like pre-calculated totals, averages etc which can be requested often.

Components/Elements of Data WarehouseMetadata: It is “data about data”. Query tools: include an end-user interface for asking questions to the database, in a process called On-Line-Analytical Processing (OLAP). They may also include automated tools called as Data Mining.Users: Finally, there is User or Users for whom the data warehouse exists and without whom it would be useless.

Data Mining

“Data Mining” or “Knowledge Discovery Databases (KDD)”, is the non-trivial extraction of implicit, previously unknown and potentially useful information from the data.

Synonyms of Data Mining Knowledge Discovery in Databases (KDD Knowledge Extraction Data Analysis Information Harvesting Data Fishing, Data Dredging Data Archaeology Information Discovery

Need of Data MiningThe massive growth of data is due to the wide availability of data in automated form from various sources as Web, Business, Research etc. We are “Data Rich but Information Poor” Data is useless, if it cannot deliver knowledge. That is why data mining is gaining wide acceptance in today’s world. Data Mining is likely to emerge as an important managerial decision making tool.

Functioning of Data Mining

The cyclical functioning of Data Mining consists of the following:Understand the situationBuilding/Developing (suitable) model/sUndertaking analysis based on the model/sInitiating appropriate actionMeasuring the resultsIterations/Repetition

Technologies used in DataMining Decision rules Decision Trees Generic Algorithms Non-Linear Regression Methods – Dependencies

are checked Case Based Reasoning – Closest past similarities of

the present situation. Neural Networks: An Artificial Neural Network (ANN)

is an information processing paradigm that is inspired by the way biological nervous systems, such as the brain, process information.

Advantages of Neural Networks

Adaptive learning Self-Organization Real Time Operation Fault Tolerance via Redundant Information

Coding

Data Mining Applications Marketing Finance Human Resources / Personnel Manufacturing Services Retail

Data Mining – Banking Case

Customers apply for a loan / credit card. Information such as age, income, employment history, education, bank accounts, existing debts etc. is provided.The bank does further verification and further decides whether to issue the loan / credit card.

Trends affecting Data Mining

Grossman has identified five external trends which affect Data Mining. They are:Data Trends - avoid dumping of data. Hardware Trends – speedy processNetwork Trends – New protocols & languagesScientific Computing Trends - SimulationBusiness Trends - predict opportunities and risks

DSS DSS are interactive information systems, that

rely on an integrated set of user-friendly hardware & software tools to produce and present information that is targeted to support the management in the decision making process.

Types of DSS Status Inquiry Systems – Searching the

available vendors, products availability, procurement, stocks

Data Analysis System – Pricing, Promotional activities, positioning

Information Analysis System – selection of vendor/product/services based on price, performance, quality etc.

Accounting Systems – ROI, Payables, Receivables could be calculated

Decision Support Systems GDSS – User Interactive computer based

systems which facilitates the solution by set of decision makers in a group.

EIS / ESS – It can handle any type of new situations from which summaries/snapshots can be generated for assisting the top management in effective decision-making.

ES – Expert Systems are computer programs that represents the knowledge of some subject specialist with a view to solvig problems or giving advice.

Decision Support Systems KBES – Knowledge based expert systems

AI - Artificial Intelligence is a technology which helps the application of computers to the areas that require knowledge, perception, reasoning, understanding which distinguish the human behaviour from computers.
