DS101 Fundamental of Information Systems Lecture 1 Golden Circle model: Simon Sinek’s theory Our Protocol and Values Mutual Respect. Quality not Quantity. Ask (Why ? What ? How? ). Self-study and Mutual Learning. Sustainability (Paperless workflow) Open source (assignments word format or code ). We do not learn only for the exam. Course Description Course Description Introduction to information systems by examining what is an IS, what are the different types, and how businesses use them. In addition, the module will examine the basic technologies, which provide the technical foundation for information systems. The workshops, which run parallel to the lectures, will be used to reinforce an understanding of areas covered in the lectures Week Lecture Topic 1 Introduction to Information systems Course 2 Outline Information systems types 3 The Web 4 Web Server 5 Introduction to Cloud Computing 6 Building Information Systems 7 Revision and Discussion 8 Mid Term Exam 9 Introduction To Salesforce 10 Salesforce Data modeling 11 The Entity-Relationship Model 12 Information Systems Analysis and Design 13 Securing Information Systems 14 Revision and Discussion What is Information System (IS)? a set of interrelated components working together to collect, retrieve, process, store, and distribute information for the purpose of facilitating planning, control, coordination, analysis, and decision making in business organizations What is Information System (IS)? People- Input-process- organization- output perspective technology perspective Input-process-output perspective People-organization-technology perspective People-organization-technology perspective Technology – the means by which data is transformed and organized for business use: Hardware Software Database Telecommunication People – the users of IS Organization -- a collection of functional units working together to achieve a common goal Choice Hotels Reservation System example: Functional units of business organizations: production sales/marketing finance/accounting human resources  maximize profit by producing goods and/or services Functional Areas of Business The manufacturing and production function is responsible for producing the firm's goods and services. There are three stages of the manufacturing/ production process: inbound logistics production outbound logistics Functional Areas of Business The sales and marketing function is responsible for finding customers for the firm's product or service and selling the firm's product or service to those customers. The sales and marketing process consists of identifying and creating markets developing markets maintaining markets Functional Areas of Business The finance and accounting function is responsible for managing the firm's financial assets and maintaining the firm's financial records. The finance process involves managing the firm's financial assets, whereas the accounting process is involved primarily in financial record keeping. Functional Areas of Business The human resource function is responsible for attracting and maintaining an appropriate work force for the firm. The human resources process entails attracting the work force developing the firm's work force to meet the firm's personnel needs maintaining the work force Computer vs IS literacy IS in Business Business functions Business processes A series of interrelated activities through which work is organized and focused to produce a product or service Business levels Strategic (long range planning) Tactical (co-ordinate & supervise) Operational (produce product & service) The order generation and fulfillment process (Fig. 2.2) Role of IS in Business Competitive advantage Low-cost (value chain) Market niche Product differentiation Customer loyalty Globalization People (language) Organization (culture) Technology (telecommunication) Role of IS in Business Quality Process simplification Benchmarking Customer focus Cycle time reduction Improve design & production Error reduction Role of IS in Business Reengineering Business processes redesign Ethical & social responsibility Information rights & privacy Intellectual property Accountability & liability Quality of life IS Approach to Problem Solving Systems Analysis Systems Design Systems Analysis & Design Systems Analysis Problem analysis (what) Information gathering (where & why) Decision making (how) Establish objectives Determine feasibility Choose best solution Systems Design (Input, Process, Output, Procedures, Control) Logical design Systems Analysis & Design Systems Design Logical design (what will the system do?) Input: content, format, source, volume, frequency, timing Process: rule, model, formula, timing Output: content, format, organization, volume, freq., timing Storage: data, format, organization, relationship, volume Procedure: manual activities, rule, sequence, timing, location Control: security, accuracy, validity, supervision Physical design (how the system will work?) Input: keyboard, voice, scanner Process: PC, operating system, software Output: print-outs, files, audio Storage: tape, CD Procedure: batching, backup, auditing, data entry Control: batch control, password, audit logs Implementation (coding, testing, training) Technology perspective to problem solving Organizational perspective to problem solving People perspective to problem solving
