Designing and documentation is a process that entails mapping out the different steps from start to the very end. A single mistake in such a case can result in the entire system breaking down, resulting in a major loss of time, money, capital equipment, and might even threaten the safety of the manpower employed to carry out the process. Therefore, flowcharts are constructed to design and document such procedures. Let us show you the best ways to construct a flowchart, with FAQs, examples, design tips, and suggested PowerPoint flowchart templates.

What is a Flowchart?
A flowchart is a diagram used for representing workflow, programs, processes, and for representing algorithms. To make a flowchart, you have to go through various steps and ensure strict adherence to how each step is presented visually.
Typically, flowcharts follow a strict rule regarding the type of symbols used for representing each step. These symbols have specific meanings, representing the start, process, connectors, input, output, end, etc. These symbols are represented using different shapes such as a circle, diamond, oval, arrow, and the like.
Is it Flow Chart or Flowchart?
The term flowchart or flow chart are both used for diagrams that depict processes, workflow, programs, and computer algorithms using a set of symbols that have pre-defined functions. This diagrammatic representation is also known by other terms such as a flow sheet, flow diagram, workflow diagram, and business flow diagram.
Brief History of Flowcharts
The use of flowcharts to document processes can be traced back to the early 1920s. Flowcharts were the brainchild of American engineers Frank and Lillian Gilbreth. During 1921, both Frank and Lillian introduced the concept to the American Society of Mechanical Engineers (ASME), as flow process chart. These tools soon found their way to the curricula of industrial engineering and was used by other engineers. One such individual was Allan H. Mogensen, who during the 1930s, began training business people using the same tools. Similarly, Mogensen’s student, Art Spinanger, used the concept at Procter and Gamble to develop the ‘Deliberate Methods Change Program’.
What caught the attention of people from across different industries was the simplicity of using a flowchart. Even today, flowcharts are deemed as diagrams used for documenting and representing simple processes. In recent years, flowcharts have evolved into other forms including Unified Modeling Language (UML) activity and Event-driven Process Chain (EPC) diagrams.
What is the Purpose of a Flowchart?
Flowcharts are used for the documentation, design, and depiction of a process, program, or algorithm. Flowcharts help map the aforementioned, with a visual map of the flow, and control of resources. Flowcharts are used to communicate processes in various fields. A presentation flowchart can be used as a tool to break down information and clearly explain it to an audience, making it easy to understand and follow. The purpose and fields across which flowcharts are used are explained in detail below.
Different Types of Flowcharts
Different types of flowcharts can be divided into four broad categories. These include:
- Document flow charts
- Data flow
- System flow
- Program flow charts.
There are also other types of flow chart categories, such as swim lane, EPC, workflow, SDL, DFD diagram, etc.
While flowcharts have been defined differently by various authors, the four broad categories that define flowcharts according to Alan B. Sterneckert in his book ‘Critical Incident Management’ in 2003 include the following:
1. Document Flowchart:
A document flowchart shows controls over document flow through a system. Such a chart is constructed from left to right, showing the flow of documents across business units.
2. Data Flow Chart:
Such a flowchart is primarily used to show the channels through which data is transmitted rather than the flow of controls.
3. System Flowchart:
A system flowchart shows the physical or resource level controls. This type of chart displays the flow of data within a system and the decisions made to control events.
4. Program Flowchart:
As the name suggests, this type of flowchart shows the controls in a program used in a system.
Flowchart Symbols — Meaning of the Different Symbols in Flowcharts
Every flowchart symbol has a pre-defined meaning. Using these symbols in the right order at the correct part of the chart is essential to accurately depict the flowchart. Below is a list of common symbols used in a flowchart.
Terminal Symbol
A terminal is an oval or rounded rectangle shape used at the beginning and end of a flowchart. Terminals come with a word like ‘Start’ or ‘End’ to indicate the beginning or conclusion of a process. A terminal (a.k.a. Terminator symbol) might also come with a phrase, such as ‘Receive Product’ to explain the phase of the process. Sometimes it is also displayed as ‘Start’ or ‘Stop’.
Flowline Symbol
A flowline shows the flow represented by various symbols by connecting one symbol to another via a line. If the process is not standard, arrowheads are added to flowlines. This might be the case when the flow is not in a standard format such as top to bottom or left to right.
Process Symbol
This is a rectangle shape used for representing a set of operations with a change of form, location, data, value, etc. It is the action step or process represented in the flowchart.
Predefined Process Symbol
This symbol has a rectangle shape with vertical edges on both sides and indicates a subroutine or predefined process in the chart.
Decision Symbol
Represented with a diamond shape, the decision symbol in a flowchart comes with a yes or no or true or false question/test, determining the path of the program.
Input/Output Symbol
As the name implies, the rhomboid input/output symbols indicate inputting or outputting of data.
On-page Connector Symbol
Represented with a small circle, the on-page connector uses letters inside the shape to show where the adjoining connector is present.
Off-page Connector Symbol
Represented as a home plate like a pentagon, the off-page connector indicates that the target is on another page.
Annotation Symbol
This open rectangle shape indicates additional information about a step in the flowchart.
Data File or Database Symbol
This cylinder shape represents a disk drive.
Document Symbol
The document symbol represents one or more documents. For single documents, a single wavy rectangle is used, whereas a stacked wavy rectangle shape represents multiple documents.
Manual Operation Symbol
The trapezoid symbol in a flowchart represents an operation or process adjustment that needs to be made manually.
Preparation or Initialization Symbol
This elongated hexagon symbol is used when initializing a routine or setting a switch.
How to Make a Flowchart?
You can construct a professional-looking flowchart by following the five basic steps mentioned below.
Step 1. Determine the Purpose of the Flowchart
Before you start constructing your flowchart, you should have clarity regarding its purpose and gather information. Is the chart supposed to help employees understand or execute a process, determine the workflow, facilitate an operation or routine task or show the various steps for executing a program or algorithm?
Step 2: Pick a Flowchart Design and Template
Depending upon your needs, you can pick different flow chart templates across various platforms. For example, to create a PowerPoint flowchart for a presentation, you can pick a template from our suggested PowerPoint templates mentioned in the section below.
The flow chart templates by SlideModel can be edited in Microsoft PowerPoint and Google Slides, but then you can reuse them in any other presentation or word processing tool such as Microsoft Word or Google Docs. By using copy & paste, you can insert the flow chart design into another document.
Step 3: Make a Flowchart According to the Correct Symbols
Sometimes, flow charts are also constructed using various images and icons that do not correspond to the standard flowchart format. For example, ‘how a bill becomes a law flowchart’ might contain icons and symbols related to the judiciary, the parliament, or other icons that might appear eye-catching for making a flowchart infographic. However, the standard format is to use the symbols in the correct order, such as using the standard symbols to show the start, process, decision, connectors, etc.
Step 4: Ensure Your Flowchart is Properly Labeled and Connected
Using the right symbols, with the required terms is necessary to ensure that the flowchart can be read and understood correctly. This is vital for processes to be executed and understood properly. Even a slight error in constructing a flowchart used for a process or program can at times have dire consequences. Resulting in the loss of time, money, equipment and affecting manpower. If you use a Flowchart maker, typically the flowchart tool provides text placeholders. It is essential to replace the default labels by the actual text to use.
Step 5. Stylize Your Flowchart
To make the flowchart easy to understand and eye-catching, you can add colors, text, and icons in a manner that it appears visually pleasing, without compromising on the standardization of the chart. You can use color coding for symbols, as well as different font styles and stylish versions of flowchart icons to make your chart easy on the eyes.
Flowchart Example: How a Bill becomes a Law Flowchart
How a bill becomes a law flowchart shown below maps the process from the draft bill to the stage when the law is enacted.
