Management

• The act, art, or manner of managing, handling, controlling directing, etc.

• Origin: to train (a horse) in his paces; cause to do exercises of the manage

• To control the movement or behavior of; handle; manipulate

• To have charge of; direct; conduct; administer

• To get (a person) to do what one wishes

Webster’s Dictionary

Information

•Derived from the Latin verb informo, informare, meaning to “give form to”

• Information etymologically connotes an imposition of organization upon some indeterminate mass or substratum, the imparting form that gives life and meaning to otherwise lifeless or irrelevant matter

• Data that have been shaped by humans into a meaningful and useful form.

Schoderbek, Schoderbek & Kefalas

SYSTEM

Webster’s New World Dictionary

• A set or arrangement of things so related or connected as to form a unity or organic whole

• A set of facts, principles, rules, etc. classified or arranged in a regular, orderly form so as to show a logical plan linking the various parts.

• A method or plan of classification or arrangement

7

SYSTEMA system is defined as (1) a set (2) of objects (3) together with relationships (4) between the objects and between their attributes (5) related to each other and to their environment (6) so as to form a whole.

Schoderbek, Schoderbek & Kefalas

SET — any well defined collection of elements or objects within some frame of reference

OBJECTS — objects are elements of a system [INPUTS (serial, probable, or feedback), PROCESS (transformation), OUTPUTS (Intended, waste, or pollution)] Efficiency - ratio of output to input

RELATIONSHIPS — the bonds that link objects together (Symbiotic, synergistic, and redundant)

ATTRIBUTES — attributes a properties of both objects and relationships (defining/accompanying characteristics)

ENVIRONMENT — includes not only that which lies outside the system’s complete control but that which at the same time also determines in some way the system’s performance.

WHOLE — defining attribute.

5 forces and value chain Organizational processes

16

Competitive Intelligence

• Such information-gathering drives business performance – by increasing market knowledge – improving knowledge management – raising the quality of strategic planning

One of the most important aspects in developing a competitive advantage is to acquire information on the activities and actions of competitors.

However once the data has been gathered it must be processed into information and subsequently business intelligence. Porters 5 Forces is a well-known framework that aids in this analysis.

17

Porter’s Competitive Forces Model

• The threat of entry of new competitors• The bargaining power of suppliers• The bargaining power of customers (buyers)• The threat of substitute products or services• The rivalry among existing firms in the industry

The model recognizes five major forces that could endanger a company’s position in a given industry.

The Value ChainValue Chain -- The set of processes a firm uses to create value for its customers ( see pg 58)

(an abbreviated version of the term value added chain from economics)

The Value Chain includes: Primary Processes -- that directly create the value the firm’s customer perceives, and

Support Processes -- that add value indirectly by making it easier for others to perform the primary processes

20

The Value ChainAccording to the value chain model (Porter, 1985), the activities conducted in any organization can be divided into two parts: primary activities and support activities.

Primary activities are those activities in which materials are purchased, processed into products, and delivered to customers. Each adds value to the product or service hence the value chain. Inbound logistics (inputs) Operations (manufacturing and testing) Outbound logistics (storage and distribution) Marketing and sales Service

21

The Value Chain (Continued) Unlike the primary activities, which directly add value to

the product or service, the support activities are operations that support the creation of value (primary activities) The firm’s infrastructure (accounting, finance, management) Human resources management Technology development (R&D) Procurement

The initial purpose of the value chain model was to analyze the internal operations of a corporation, in order to increase its efficiency, effectiveness, and competitiveness. We can extend that company analysis, by systematically evaluating a company’s key processes and core competencies to eliminate any activities that do not add value to the product.

• Transaction Processing Systems (TPS) - - handles and processes daily exchanges (transactions)

• Office Automation Systems (OAS) - - produces documents, plans, schedules

• Management Information Systems (MIS)– produces managerial reports

• Decision Support Systems (DSS) - – supports and assists in all problem-specific decision

making.

• Artificial Intelligence (AI) and Expert Systems (ES) -- Knowledge Work Systems (KWS)- is an information system that can make suggestions and reach solutions in much the same way as a human expert.

Example When customers make a purchase from anywhere in the world using EBay's' online auctions, the firms' sales process integrates with a variety of partner and processes that include payment process and its internal process. (Sambamurthy et al., 2003)

Sara Lee uses its ability to analyze the sales of retailers it serves. In doing so, they can identify trends and exceptions, draw comparison, perform calculations and obtain fast answers (Turban & Aronson, 2000).

BP uses 3-D imaging rooms equipped with state-of-the art videoconferencing systems for helping its engineers gather in any of the company's 15 imaging rooms and tap into and share data over the network (Echikson, 2001).

Strategic Information Systems -- Information systems that play a major role in a product’s value chain.

Although there is no clear-cut separation between strategic information systems and other systems, a number of characteristics indicate whether an information system should be considered strategic.

Systems should be considered strategic if :•they help differentiate the product form its competitors; •if the customers directly perceive the value of the information system to them; or •if the product’s production, sales, and service require the system.

Lewin’s Change Model

•Unfreezing • preparing for change • create felt need • disrupt existing attitudes, behaviors

•Changing • modify situation • sustain effort • clear goals • adequate preparation

•Refreezing • Reinforce desired behavior • Support • Evaluation

Change Agent• Responsible for changing individual & system (organizational) behavior • IS professional as change agent • Facilitate & support change processes

35

Resistance to Change Causes Fear of unknown Security No felt need Power/threatened Rumors Timing Resources

Strategies

Communicate Clarify Show benefit Enlist key people Accurate info Delay Provide support

Targets of Change

Purpose, strategy, objectives Structure Technology Culture Tasks People

All are interrelated

Planned Change Deliberate and intentional

Response to performance gap

Gap between actual & desired state

Radical • massive restructuring “frame-breaking”

Incremental • “frame-bending” • continuous improvement

Change

36

Change Strategies

Force-coercion

Authority power Good for unfreezing stage

Rational persuasion

Expert power Convince of benefits of change

Shared power Active, real involvement Takes longest, lasts longest

Resistance to Change

• Attitudes and behaviors

• View as useful feedback

• Educate / communicate

• Participation = commitment

• Provide support re: external constraints

• Negotiate trade-offs

• Manipulation: speed, use power
