    Study Notes

    Chapter 1: Introduction to System Analysis Design

    • This chapter introduces fundamental concepts of System Analysis and Design (SAD).
    • The primary objective is to improve organizational efficiency through employee efficiency and applying software solutions to critical business tasks.

    Learning Objectives

    • Students should be able to define the importance of SAD.
    • Students should be able to identify the roles and responsibilities of a System Analyst.
    • Students should be able to differentiate the four types of Information Systems (IS).
    • Students should be able to identify the essential tools and techniques utilized in SAD.

    1.1 Overview of System Analysis and Design

    • Companies use SAD to create and maintain systems handling core business functions.
    • The primary goal is enhancing worker efficiency through software application.
    • A structured approach ensures success.
    • The Systems Analyst's role hinges on: understanding an organization's goals, structure, and processes; and a deep knowledge of using information technology advantageously.

    1.1 Overview of System Analysis and Design (continued)

    • Improving organizational systems through software development and employee training is the main goal.
    • Application software directly supports organizational functions and processes.
    • A system encompasses hardware, software, documentation, roles, controls, and users who actively utilize the software

    1.1 Overview of System Analysis and Design (continued)

    • A System includes hardware and software, documentation, specific job functions, controls to prevent theft or fraud, and the people using the software for their jobs.

    1.1 Overview of System Analysis and Design (continued)

    • Effective SAD brings improved accuracy, cost savings, flexibility for updates, and productivity boosts.

    1.2 Roles as System Analyst

    • System Analysts study organizational problems.
    • They determine the best approach to improve the organization using people, methods, and information technology to enhance existing systems and define requirements of new systems.

    1.2 Roles as System Analyst (continued)

    • Key skills include analytical abilities, understanding organizations, problem-solving, system thinking, and technical understanding of technology potential/limitations.

    1.2 Roles as System Analyst (continued)

    • Managerial skills are vital for effectively managing projects, resources, risks, and change, alongside effective written and oral communication.

    1.3 Type of Information System

    • Information systems collect, process, store, and disseminate information.
    • Various information systems support diverse activities: communication, banking, shopping online, etc.

    1.3 Type of Information System (continued)

    • Organizations utilize information systems for internal and external communication with customers, suppliers, management, essential business operations, and marketing campaign management

    1.3 Type of Information System (continued)

    • An illustrative diagram depicts different information systems based on the management level, from top strategic managers to operational-level staff.

    a. Transaction Processing System (TPS)

    • A TPS is an information system designed for routine, repetitive, structured business transactions, providing accurate and efficient data handling.
    • TPS is the backbone of operational-level processes, ensuring smooth execution of core business functions.
    • Examples include retail POS systems, banking ATMs, airline reservations, and manufacturing tracking of materials use. A key example given is the payroll system.

    a. Transaction Processing System (TPS) (continued)

    • Examples of TPS uses are: Retail Point-of-Sale systems, Banking ATMs and Online banking, Airlines reservation systems, and Manufacturing systems for tracking production schedules and raw material usage (supply chain management).

    a. Transaction Processing System (TPS) (continued)

    • The diagram shows a payroll TPS system. Data flows from different departments into a master file then a payroll system is used to calculate pay, taxes, and other deductions then the results go to reporting.

    b. Management Information System (MIS)

    • A Management Information System (MIS) transforms raw transaction data into useful and meaningful forms for decision-making.
    • MIS integrates people, technology, and processes to achieve organizational goals.
    • It supports operational efficiency, enhances decision-making, and gives a competitive edge.
    • It bridges the gap between data collection systems (TPSs) and decision support systems (DSSs)

    b. Management Information System (MIS) (continued)

    • MIS functions: data collection, processing, storage, report generation, and problem identification.
    • Examples: Sales reporting (by region or product), inventory monitoring, financial reporting, and human resource analysis.

    b. Management Information System (MIS) (continued)

    • Different types of information systems are targeted at different management levels (strategic, management, and operational).

    b. Management Information System (MIS) (continued)

    • A diagram of a financial management system is given.

    c. Decision Support System (DSS)

    • A DSS supports complex decision-making using data analysis and insight generation.
    • It creates an interactive environment for semi-structured or unstructured problem-solving.
    • Managers and experts utilize DSS for informed decisions.

    c. Decision Support System (DSS) (continued)

    • DSS functions include: data collection, analysis, scenario evaluation, decision support and visualization. Key examples are Financial Planning tools, Supply Chain analysis tools, Customer relationship management tools, and Healthcare management tools

    c. Decision Support System (DSS) (continued)

    • A diagram of a DSS shows how data is analyzed, processed, and resulting recommendations are generated.

    d. Expert System (ES)

    • An ES is an Al-based system that mimics human expertise in specific domains.
    • It uses a knowledge base, reasoning rules, and algorithms to solve complex problems requiring human expertise.
    • Examples include medical diagnosis systems (like MYCIN), engineering design tools (CAD), customer support chatbots, financial assessment tools, legal advice systems.

    d. Expert System (continued)

    • Expert systems utilize a knowledge base and inference engine to emulate human expertise. Illustrations of medical diagnostics and agricultural management systems show how real-world problem-solving can occur.

    1.4 Tools and Techniques for SAD

    • Tools for creating diagrams (DFDs, ERDs, use cases) and process flows (flowcharts).
    • Modeling tools (UML, BPMN) for object-oriented design.
    • Prototyping tools for UI/UX design.
    • CASE tools for automating project tasks (code generation, database design).
    • Techniques for gathering requirements (interviews, surveys), analysis (SWOT, gaps), design (structured, object-oriented), and validation (walkthroughs).
