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
•
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 Webster’s New World Dictionary

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

Organizational processes 15
Competitive Intelligence
One of the most important aspects in developing a competitive advantage is to acquire information on the activities and actions of competitors.
• Such information-gathering drives business performance – by increasing market knowledge – improving knowledge management – raising the quality of strategic planning
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.
16
Porter’s Competitive Forces Model
The model recognizes five major forces that could endanger a company’s position in a given industry.
• • • • • 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 External Competitive Forces 17

The Value Chain
Value 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 19
The Value Chain
According to the
value chain model
conducted in any organization can be divided into two parts: primary activities and support activities.
(Porter, 1985), the activities
Primary activities
chain.
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 Inbound logistics (inputs) Operations (manufacturing and testing) Outbound logistics (storage and distribution) Marketing and sales Service 20
The Value Chain
(Continued)
Unlike the primary activities, which directly add value to the product or service, the activities)
support activities
are operations that support the creation of value (primary 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.

Information Systems Process Systems and Knowledge Systems
Type of system Process systems Quantitative / Structured Quantitative / Structured Knowledge systems Qualitative / Unstructured Type of Data Examples of technology ERP / TPS Business intelligence Content Management Example SCM Data Mining Information Portals CRM Collaborative tools 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).

- 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 34
Change Resistance to Change Planned Change Causes
Fear of unknown Security No felt need Power/threatened Rumors Timing Resources Deliberate and intentional Response to performance gap Gap between actual & desired state Radical • massive restructuring “frame-breaking” Incremental • “frame-bending” • continuous improvement
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 35
Change
• • • • • • •
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
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 36
