    Study Notes

    Introduction to Information Technology - Software Engineering Module

    • The module was prepared by Dr. Mohammad Malkawi, Dr. Moh'd Radaideh, Dr. Malik Qasaimeh, and Dr. Hamza Al-Kofahi.
    • The module was developed for Jordan University of Science and Technology.
    • The date of the module is October 29, 2022.

    Part 1: Software Engineering Introductory View

    • Origin of Software Engineering: Software Crisis:
      • Software Engineering emerged from the Software Crisis of the 1960s, 1970s, and 1980s.
      • The crisis highlighted problems in software development, including project budget overruns, schedule delays, property damage caused by software defects, and identity theft due to poor security.
      • The emphasis of software crisis evolved from productivity to quality.
      • Some examples of these issues include the OS/360 Operating System, and the catastrophic failure of the Therac-25 incident.
      • Software defects can cause significant harm, such as in medical equipment.
    • Why Software Engineering?
      • A pie chart shows expenditure on Software Projects totaling $96.7 million, with 45% delivered but not successfully used, 30% paid for but not delivered, 20% used with extensive rework and ultimately abandoned, and a very small percentage (2%) used as delivered.
    • Scientist vs. Engineer:
      • A computer scientist proves theorems about algorithms, designs languages, and defines knowledge representation schemes. They have infinite time.
      • An engineer develops solutions for application-specific problems for clients, using computers, languages, tools, techniques, and methods. Engineers work in multiple application domains and have 3 months to achieve the outcome.

    Software Engineering - A Problem Solving Activity

    • Analysis: Understanding the problem and breaking it down into smaller parts.
    • Synthesis: Combining the pieces into a structured solution.
    • Techniques (Methods): Formal procedures for producing results using well-defined notation.
    • Methodologies: Collections of techniques applied throughout software development, unified by a philosophical approach.
    • Tools: Instruments or automated systems to execute techniques.

    Frequently Asked Questions about Software Engineering

    • What is Software? Computer programs and documentation, developed for a specific customer or general market.
    • Attributes of Good Software: Functionality, performance, maintainability, dependability, and usability.
    • What is Software Engineering? An engineering discipline concerned with all aspects of software production, from specification to maintenance.
    • Fundamental Software Engineering Activities: Specification, development, validation, and evolution.
    • Difference between Software Engineering and Computer Science: Computer Science focuses on theory and fundamentals, while Software engineering concerns the practical development of software.
    • Difference between Software Engineering and System Engineering: System engineering concerns all aspects of computer-based systems, including hardware, software, and process engineering. Software engineering is part of this process.

    Frequently Asked Questions about Software Engineering (cont.)

    • Key Challenges: Coping with diversity, reduced delivery times, and building trustworthy software.
    • Software Engineering Costs: Roughly 60% of expenses are for development, 40% for testing. Often, evolution (change) costs exceed initial development costs for custom software.
    • Techniques/Methods: Different methods work best for different systems (e.g., safety-critical systems require different specifications than game development).
    • Web's Impact: The web has enabled software services and distributed systems. It has also spurred advancements in programming languages and software reuse.

    Essential Attributes of Good Software

    • Maintainability: Software should be adaptable to meet evolving customer needs.
    • Dependability and Security: Software should not cause physical or financial harm and be protected from malicious users.
    • Efficiency: Should not waste resources (e.g., memory, processing time).
    • Acceptability: Software must be understandable, usable, and compatible with other systems.

    Software Engineering

    • Definition: An engineering discipline concerned with all aspects of software production, from initial specification to ongoing maintenance.
    • Engineering Discipline: Uses appropriate theories and methodologies to address organizational and financial constraints.
    • Software Production: Involves technical development processes, project management, and tooling.

    Importance of Software Engineering

    • Reliance: Increasing reliance on advanced software systems by individuals and society.
    • Reliability and Cost-Effectiveness: The need for reliably producing software economically and quickly.
    • Cost Considerations: Changing and maintaining software after implementation often constitutes a large fraction of the overall cost.

    General Issues Affecting Most Software

    • Heterogeneity: Software systems must operate across a variety of networking devices and systems.
    • Business and Social Change: Software must adapt to rapid changes in business practices and societal needs.
    • Security and Trust: Ensuring the security and trustworthiness of software in an increasingly interdependent world.
