    Study Notes

    Software Development

    • A computer application (app) is a software program that executes on a computing device to perform a specific set of functions.
    • An information system is a set of interrelated components that collects, processes, stores, and provides information needed for business tasks.
    • Systems analysis focuses on understanding and specifying the goals of an information system.
    • Systems design defines and describes the details of the system that meets the identified need.

    Systems Development Lifecycle (SDLC)

    • The SDLC consists of six core processes:
      • Identify the problem or need and obtain approval
      • Plan and monitor the project
      • Discover and understand the problem or need
      • Design the system components
      • Build, test, and integrate system components
      • Complete system tests and deploy the solution
    • A project is a planned undertaking that has a beginning and an end, producing a defined result.
    • Project development requires knowledge of systems analysis and design tools and techniques.
    • A system development process is a specific approach used to develop a particular information system. Examples include the Unified Process (UP), Extreme Programming (XP), and Scrum.
    • Modern methodologies often employ Agile and Iterative development.

    Agile and Iterative Development

    • Agile development emphasizes flexibility to anticipate new requirements during development.
    • Iterative development builds the system piece-by-piece through multiple iterations.

    Initial Activities

    • Core process 1: Identify the problem and document the objective of the system in a System Vision Document.
    • Core process 1: Obtain approval to start the project by meeting with key stakeholders including management.

    Business Benefits

    • The text outlines the potential business benefits of deploying a new system. These may include:
      • Improved communication between stakeholders
      • Accurate and updated information about suppliers
      • Faster order placement for new merchandise

    Work Breakdown Structure

    • This describes the work and covers core processes 3, 4, 5, and 6.
    • The example includes preliminary class diagrams, use cases, and activity diagrams.

    Managing the Project

    • Designing is a complex activity with multiple levels, and diagrams often supplement each other.
    • Programming is done concurrently with designing, meaning it is a continuous cycle.

    First Iteration Recap

    • The text outlines a 6-day example of a small project iteration.
    • Most iterations are longer, ranging from 2 to 4 weeks.
    • End users need to be actively involved throughout the process.
    • Design and programming occur concurrently during specific stages within each iteration.

    Summary

    • The text focuses on developing information systems that address organizational needs.
    • It presents a complete example of a small information system development process.
    • System development includes six core processes as outlined in the SDLC.
    • Subsequent chapters will elaborate on each of the core processes introduced in chapter 1.
