What is a Flowchart?

Flowcharts visually represent a process or workflow in a step-by-step manner. It breaks down a process into steps, usually in a sequential order. Each step is represented by blocks or ovals, and connected by lines or arrows.

A flowchart is most commonly used in the planning stages of a project, in order to map out the various steps in a workflow. By extension, a flowchart can be used to document, communicate, and analyse a workflow. They may also be used in more technical fields, such as programming, to illustrate data flow.

The primary benefit of flowcharts is its clarity. You are able to communicate what might be a complex process in a few simple shapes. It is also incredibly useful for improving communication and understanding amonst teammates regarding a certain process or workflow.

How to Make a Flowchart?

Most of us do not know how to deal with flowcharts when we are novices. However, practice makes perfect. A good flowchart helps to understand the systematic flow of information in the system. If a flowchart is not created properly, it may mislead the system designer or result in fatigue consequences. Therefore, you must create flowcharts carefully. I would always suggest you use flowcharts to make the process of a system and its flow easy to understand.

Although there are many symbols that can be used in flowcharts to represent different kinds of steps, accurate flowcharts can be created using very few of them (e.g. Process, Decision, Start, delay, cloud).

One of basic flowchart symbols is a simple action, which can be anything from striking an anvil to make a cash payment. It is represented by a box containing a description of the action. The mapping of "what follows what" is shown with arrows between sequential action boxes, as shown in the illustration. This also shows the boxes for the flowchart's start and end points, in which there are normally one for each.

Processes become more complex when decisions must be made, which means a set of actions must be taken. The decision is shown in a flowchart like a diamond-shaped box containing a simple question to which the answer is "yes" or "no," as shown in Fig. 2. More complex decisions are made up of combinations of simple decision boxes.

Decisions in Flowcharts

Processes often go wrong around decisions, as either the wrong question is being asked or the wrong answer is being given.

Where boxes cannot be directly connected with lines, the separated lines are coordinated with connector boxes containing matching names. This typically occurs where lines cross onto another page as shown in the illustration.

Continuing Flowcharts across pages

By using multiple connector boxes, it is very easy for flowcharts to become very complex to understand. In terms of size, A one-page flowchart is perfect.

Large processes can be broken down into a hierarchical set of smaller flowcharts by representing a lower level process as a single sub-process box. This behaves like a normal action box at the higher level, but can be "zoomed into" to expose another flowchart, as shown in Fig. 4.

Sub processes - Flowchart

An additional "action" box that can be useful when analyzing processes is the wait box, which highlights a delay (i.e. no action) like the illustration. This is a typical point where the overall cost of a process may be improved by acting, possibly on other processes, to reduce the delay.

Guidelines for Making a Flowchart

Are you confused about how to draw a flowchart? Here are some guidelines and tips that can be used to simplify the process of creating a high-quality flowchart.

  1. Agree on standard flowchart symbols as there are several conflicting common uses.
  2. Draw a start box at the top of the work area.
  3. Add the first box below the start box, identifying the first action simply by asking, "What happens first?". Add an appropriate box around it.
  4. Add subsequent boxes below the previous box, identifying each action by asking, "What happens next?". Draw an arrow from the previous box to this one.
  5. Describe the process to be charted.
  6. Start with a trigger event.
  7. Note each successive action concisely and clearly.
  8. Go with the main flow (put extra details in other charts).
  9. Make cross references to support information
  10. Gather the team who are to work on describing the process. These should include people who are intimately involved in all parts of the process, to ensure that it gets described as it actually happens, rather than an idealized view.
  11. Follow the process through to a useful conclusion (end at a target point).
  12. If the final diagram is to be used as a part of a formal system, make sure that it is uniquely identified

Basic Flowchart Symbols

A few of commonly-used flowchart symbols are explained here. For more information , please refer to the expandable link - flowchart symbols.

Name + Description
Start or Terminator
Start or Terminator

Use this shape for the beginning or ending step of your process.


This shape stands for a step in your process.


It indicates a point where the outcome of a decision dictates the next step. There can be various outcomes, but usually there are just two - yes and no.


Document shape represents a step that results in a document.


This shape shows that information is coming into the process from outside, or leaving the process. It can also represent materials and is sometimes called an Input/Output shape.

Predefined Process
Predefined Process

You can Use it for a group of steps that combine to create a sub-process that is defined elsewhere, often on another page of the same drawing.


This kind of shapes represents a waiting period where no activity is done. In Process Mapping, delays are often important as they may result in adding to the cost of the product or simply delaying its production.



Use this shape for a step that results in information being stored.

Tip: The above flowchart symbols are multi-shape with floating quick buttons. You can move the pointer over the floating quick button to modify the shape quickly. For example, when you move the pointer over the quick button of a process shape, you can change it into other common shapes by selecting Data, Document, Decision, Start/End or Subprocess buttons as shown in the figure.

Flowchart Examples

Example 1: Online Sales Process Flowchart

Online Sales Process Flowchart is the visual representation of the entire process that goes in selling a product online by any company or organization. Check out the image to learn more about the aspects of the online sales process flowchart, and one process is dependent on the other.

Example 2: Linking Flowchart

To understand a company’s business flowcharts, users prefer to show business processes or workflows. In order to understand more about a company’s process, the big flowcharts are broken down into smaller ones and can later be linked to complete the entire process.

Tips for Making Flowcharts

It will help if you consider a few things when drawing a useful flowchart.

  1. Define the process boundaries with starting and ending points.
  2. Complete the big picture before filling in the details.
  3. Clearly define each step in the process. Be accurate and honest.
  4. Identify time lags and non-value-adding steps.
  5. Circulate the flowchart to other people involved in the process to get their comments.

Flowcharts don't work if they're not accurate or if the team is too far away from the process itself. Team members should be real participants in the process and feel free to describe what really happens. A thorough flowchart should provide a clear view of how a process works. With a completed flowchart, you can:

  1. Identify time lags and non-value-adding steps.
  2. Identify responsibility for each step.
  3. Brainstorm for problems in the process.
  4. Determine major and minor inputs into the process with a cause and effect diagram.
  5. Choose the most likely trouble spots with the consensus builder.
