  1. Software EngineeringIntroduction to Flowcharts Ku-Yaw Chang canseco@mail.dyu.edu.tw Assistant ProfessorDepartment of Computer Science and Information Engineering Da-Yeh University

  2. Flowcharts • Special shapes to represent different types of actions or steps in a process • Lines and arrows to show the sequence of the steps, and the relationships among them • Illustrate the steps in a process. • Quickly help identify bottlenecks or inefficiencies where the process can be streamlined or improved Ku-Yaw Chang

  3. Shapes and Symbols • Start/End • The terminator symbol marks the starting or ending point of the system. It usually contains the word "Start" or "End.“ • Action or Process • A box can represent a single step ("add two cups of flour"), or and entire sub-process ("make bread") within a larger process. Ku-Yaw Chang

  4. Shapes and Symbols • Document • A printed document or report. • Flow Line • Lines indicate the sequence of steps and the direction of flow. Ku-Yaw Chang

  5. Shapes and Symbols • Decisions • A decision or branching point. Lines representing different decisions emerge from different points of the diamond. • Input/Output • Represents material or information entering or leaving the system, such as customer order (input) or a product (output).
