In our increasingly complex world, understanding systems and processes is vital. Whether it's a business operation, a technical procedure, or a scientific phenomenon, clear and concise representation of how things work can make all the difference. One such tool that can be used to visualize and understand systems better is the system flowchart. In this article, we will delve into what a system flowchart is, when it's best to use one, the various benefits it offers, its symbols, examples and steps to create one. Keep reading.

What Is a System Flowchart

A system flowchart is a diagrammatic representation that depicts the workflow or processes involved in a system. It uses a variety of symbols, shapes, and arrows, each representing different types of tasks or steps in a process. The sequence of operations is illustrated by arrows connecting these symbols.

System flowcharts can cover a range of scenarios – from manufacturing processes in industries to software operations in information technology, business procedures in organizations, and even biological or chemical processes in science.

These charts provide a visual layout of 'what happens when' in a system, giving viewers a comprehensive understanding of how different elements within the system interact with each other to achieve the final output.

When to Use a System Flow Diagram

System flow diagrams can be employed anytime you need to understand, explain, improve, or communicate a process. Some specific situations where they are particularly useful include:

  • Planning New Processes: When setting up new operations or systems, a flowchart can help visualize the planned processes and identify potential bottlenecks or inefficiencies.
  • Troubleshooting: System flowcharts can aid in identifying issues in an existing process by illustrating each step clearly, making it easier to spot where things may be going wrong.
  • Training Purposes: For those unfamiliar with a process, system flowcharts serve as an effective visual guide detailing each step in the operation.
  • Documentation: Flowcharts provide clear and concise documentation of processes for reference and quality control purposes.

Benefits of System Flowcharts

System flowcharts bring with them numerous benefits:

  • Enhanced Understanding: By breaking down complex processes into individual steps and visually representing them, system flowcharts promote better comprehension.
  • Improved Communication: Flowcharts provide a universal language of diagrams and symbols that enhances communication among team members and across different departments.
  • Efficient Troubleshooting: As system flowcharts map out each step in a process, they make it easier to identify where problems may be occurring.
  • Effective Training Tool: For people new to a process, system flowcharts offer an easy-to-follow guide, enhancing learning and recall.
  • Streamlined Process: System flowcharts help identify redundancies and inefficiencies in a process, facilitating improvements for greater efficiency.

System flowcharts, therefore, serve as a powerful tool in visualizing, communicating, understanding, refining, and troubleshooting processes across various fields.

System Flowchart Symbols

When it comes to system flowcharts, symbols play a crucial role. They provide a universal language that enables people to understand the different steps and components of a process, regardless of their background or expertise. Below are some commonly used symbols in system flowcharts and what they represent:

  1. Oval: Ovals are typically used to denote the start and end points of a process. An oval symbol with the word 'Start' signals the initiation of the process, while an 'End' label indicates its conclusion.
  2. Rectangle: This is used to depict a process or action step. Any operation, task or activity that needs to be undertaken during the system's process is represented by a rectangle.
  3. Diamond: Decision points within the process are represented by diamonds. These could include any point where a yes/no question is asked or a choice needs to be made that will affect the direction of the process.
  4. Parallelogram: This symbol represents inputs or outputs within the system's process. Inputs might include resources or materials needed for the process, while outputs could be final products or results.
  5. Arrow: Arrows are used to indicate direction of flow, showing how the process moves from one step to another.
  6. Circle: This is used to denote an on-page connector, which means that the flow continues elsewhere on the same page.

These are just a few examples of the symbols that you might encounter when working with system flowcharts. While these are widely accepted standards, different fields or industries might use variations or additional symbols specific to their needs. The key is to always include a legend or key that clearly explains what each symbol represents to ensure clear communication and understanding.

System Flowchart Examples

Examining real-life examples of system flowcharts can provide valuable insights into how these diagrams work. Here, we will walk through three hypothetical flowcharts that represent different processes:

Example 1: Recruitment System Flowchart

In this example, the journey often starts with the "Start" oval indicating the job opening. It then progresses to a rectangle symbolizing the posting of the job advertisement. The next action could be represented by another rectangle, showing receipt of job applications.

A diamond could be used to indicate the first decision point – assessing whether an applicant meets the job criteria. If yes, the arrow leads to further steps like interviews and assessments. If not, another path would lead to a process, such as sending a rejection letter.

Following successful interviews, another diamond could indicate the final decision – to hire or not. Depending on the outcome, the chart would conclude at different 'End' points.

Example 2: University Emergency Response System Flowchart

This flowchart might start with an oval symbol representing an emergency occurrence. The following rectangle could indicate the first step – activating the emergency response team. Next might come a diamond for assessing the level of emergency and deciding on evacuation if necessary.

The chart could include various potential routes according to different emergency levels, each involving a unique set of actions like notifying authorities, evacuating premises, or providing first aid. Eventually, all paths would culminate at an 'End' oval when the situation is under control.

Example 3: Amazon Book Online Order System Flowchart

In this scenario, the flowchart might start with a customer choosing a book, depicted by a rectangle. The following step could be another rectangle showing the addition of the book to the shopping cart.

A decision diamond could be used for checking stock availability. If stock is available, the process would proceed to payment and order confirmation steps. If not, a different route could lead to a message notifying the customer about the unavailability.

After order confirmation, steps like packaging and shipping would follow. A final rectangle could represent customer receipt of the book, concluding the flowchart with an 'End' oval.

Each of these examples emphasizes how system flowcharts effectively map out processes, promoting comprehension and aiding decision-making.
