Part 1. Difinition and histoty of Flowchart?

A flowchart is a graphical representation of a system, method, or process that uses arrows and standardized symbols to show the decision points and step sequence. It is used as a visual tool to map out complex procedures, making it possible to show how information or tasks go from one stage to the next understandably and clearly.

Flowcharts are extensively used in various industries, including problem-solving, software development, project management, and business procedures to explain complex workflows in an easy-to-understand and systematic way.

They provide a visual roadmap that facilitates professionals in process analysis, optimization, and documentation, promoting effective problem-solving and communication inside businesses.

The history of the flowchart can be traced back to the early 20th century, with its roots in engineering and industrial processes. In 1921, industrial engineering and efficiency management pioneers Frank and Lillian Gilbreth developed the idea of process charts. These diagrams showed the factory workflow and were the forerunners of contemporary flowcharts.

Allan H. Mogensen further explored visualizing labor processes in the 1930s and 1940s. "Flow process charts" were first proposed by American industrial engineer Mogensen as a method for more thorough and organized workflow documentation and analysis.

With the development of computer programming in the middle of the 20th century, flowcharts became a common representational tool for program structures and algorithms. Computer scientists and programmers used flowcharts to create and record software processes, which helped standardize conventions and symbols.

ANSI/ISO Standard 5807 for Flowchart Symbols, published by the American National Standards Institute (ANSI) in the 1970s, codified flowchart symbols. A common language for designing and comprehending flowcharts across a range of sectors was established with the aid of this standardization.

Part 2. Flowcharts for Computer Programming/Algorithms

Flowcharts are widely used in computer programming and algorithm design to represent a program or algorithm's logic visually. They can be used to:

  • Plan and design algorithms: Flowcharts can be used to plan and design algorithms before they are written in code. This can help ensure that the algorithms are clear, efficient, and correct.
  • Document algorithms: Flowcharts can be used to document algorithms, making them easier to understand and maintain.
  • Communicate algorithms: Flowcharts can communicate algorithms to others, making collaboration easier.
  • Troubleshoot algorithms: Flowcharts can be used to troubleshoot algorithms by identifying and correcting errors.

Flowcharts are valuable for understanding, documenting, and communicating computer programs and algorithms. They are also used to troubleshoot problems and improve the efficiency of algorithms.

Part 3. What are the Other Scenarios to Use a Flowchart?

Flowcharts come in handy in several situations, such as the following:

what is a flowchart used for
  • Standardise processes: Flowcharts aid in standardizing processes by visually representing known procedures. This is especially helpful for maintaining operational consistency and quality control.
  • Identify and eliminate bottlenecks: Flowcharts show possible bottlenecks and inefficient parts of a process. Task flow visualization clarifies where delays or resource shortages could arise, allowing for proactive problem-solving.
  • Visualize complicated ideas or processes: A flowchart makes understanding easier when working with complex or diverse procedures. It simplifies complex ideas into easily understandable parts, assisting both producers and viewers in understanding the whole framework.
  • Make and defend your decisions: Flowcharts let you plot possible outcomes and assess the effects of various options when presented with decision points. This visual aid can help understand the ramifications and weigh possibilities when making decisions.
  • Monitor a project's development: Flowcharts, which list activities, dependencies, and milestones, are useful project management tools. This graphic depiction facilitates communication of project status to stakeholders, progress tracking, and delay identification.
  • Process documentation: Flowcharts outline and visualize a process's steps. A flowchart offers an understandable and organized depiction of any process, be it a software program, a manufacturing process, or a business procedure.

Part 4. Flowchart Symbols

Let's explore some of the most frequently utilized flowchart symbols and their definitions and names.

flowchart creation symbols
  • Flowline: Linking two blocks together, the flowline shows the direction of the process and directs the steps that follow in order.
  • Terminator: The terminal symbol indicates the beginning or finish of a process in a flowchart and the start and stop points.
  • Process: A common symbol in flowcharts, the process symbol denotes a crucial stage in the procedure.
  • Comment or Annotation: The comment or annotation symbol provides more context, allowing for more details about a particular phase.
symbols used for flowchart creation
  • Decision: The decision symbol denotes crucial decisions in the process, capturing true/false or yes/no decisions that determine the course of action.
  • Stored data: This element denotes the storage or retrieval of information and is a symbol for data files or databases.
  • "Or" Symbol: This denotes processes that continue in three or more branches and shows branching pathways in the flow.
  • Input/Output: The input/output sign indicates the process of data entering or leaving by showing the transfer of external data.
flowchart creation process symbols
  • Off-Page connector: Signifying the continuation of the process beyond a single page, the off-page connector bridges symbols on other pages.
  • On-Page connector: The dot connector reduces clutter and streamlines the flowchart structure by connecting symbols on the same page.
  • Summoning junction symbol: The summoning junction symbol unites many routes by merging several branches into a single procedure.
  • Predefined process: This symbol points to a referenced and established procedure already defined elsewhere.
symbols to create flowcharts
  • Display: The display symbol highlights the presentation of relevant data and denotes a stage that highlights significant information.
  • Document: This symbol, for a single document, highlights a particular written or digital record.
  • Delay: To account for temporal gaps in the process, the delay indicates and schedules for brief intervals of inactivity.
  • Manual input: The manual input sign emphasizes manual participation when transmitting data or information that must be entered into a system by hand.
