Standard Flowchart Symbols and Their Usage

Basic Flowchart Symbols

Flowcharts are the ideal diagrams for visually representing business processes. For example, if you need to show the flow of a custom-order process through various departments within your organization, you can use a flowchart. This paper provides a visual representation of basic flowchart symbols and their proposed use in communicating the structure of a well-developed web site, as well as their correlation in developing on-line instructional projects. A typical flowchart from older Computer Science textbooks may have the following kinds of symbols: Start, End, Process, Arrow, input and output.

Flowcharts may contain other symbols, such as connectors, usually represented by circles, to represent converging paths in the flow chart. Circles will have more than one arrow coming into them but only one going out. Some flow charts may just have an arrow pointing to another arrow instead. These are useful to represent an iterative process (in Computer Science this is called a loop). A loop may, for example, consists of a connector where control first enters, processing steps, a conditional with one arrow exiting in the loop, and one going back to the connector. Off-page connectors are often used to signify a connection to a (part of a) process held on another sheet or screen.

A flowchart is described as "cross-functional" when the page is divided into different "lanes" describing the control of different organizational chart units. A symbol appearing in a particular "lane" is within the control of that organizational unit. This technique allows the analyst to locate the responsibility for performing an action or making a decision correctly, allowing the relationship between different organizational units with responsibility over a single process.

Standard Flowchart Symbols

Flowcharts use special shapes to represent different types of actions or steps in a process. Lines and arrows show the sequence of these steps, and the relationships between them.

Standard Flowchart Symbols

Start and end symbols, represented by lozenges, ovals or rounded rectangles, usually contain the word "Start" or "End", or another phrase signaling the start or end of a process, such as "submit enquiry" or "receive product".

Arrows show what's called "flow of control" in computer science. An arrow coming from one symbol and ending at another symbol signifies flow passes to the symbol the arrow points to.

Processing steps are represented by rectangles. Examples: "Add 1 to X"; "replace identified part"; "save changes" or similar.

Input/Output are represented by a parallelogram. Examples: Get X from the user; display X.

Conditional (or decision) is represented by a diamond (rhombus). These typically contain a Yes/No question or True/False test. This symbol is unique in that it has two arrows coming out of it, usually from the bottom point and right point, with one corresponding to Yes or True, and the other one corresponding to No or False. The arrows should always be labeled. More than two arrows can be used, but this is normally a clear indicator that a complex decision is being taken, in which case, it may need to be broken-down further, or replaced with the "pre-defined process" symbol.

A number of other symbols that have less universal currency, such as:

Document represented by a rectangle with a wavy base;

Manual input represented by a rectangle, with the top irregularly sloping up from left to right. An example would signify data-entry from a form;

Manual operation represented by a trapezoid with the longest parallel side upmost, to represent an operation or adjustment to process that can only be made manually.

Data File represented by a cylinder

Workflow Shapes

Workflow relationships are where work is done by different departments in a fixed sequence. This means that one department needs to finish its job before work can continue in another department. The development and maintenance of these work flow relationships is very important for managers because they depend on the preceding areas for his or her own work, and responsible for managers and workers at different stages further down the chain.

Audit Flowchart Shapes

The following shapes are similar to the basic flowchart symbols but are specially used in the audit flowchart.

The Flowchart Symbols and Their Usage

Process represents a step in your process.

Process Shape

Predefined process indicates a set of steps that combine to create a sub-process that is defined elsewhere, often on another page of the same drawing.

Predefined process shape

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

Decision shape

Terminal points indicates the starting and ending points of a process.

start shapes

terminator shape

Data shape indicates that information is coming into the process from outside, or leaving the process.

storedd data shape

Delay shape 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.

delay shape

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

database shape

Step represents a single step within a process, and usually contains the name of a specific action.

Page symbols refer to individual web pages, which may or may not contain multiple elements.

File symbols represent those data elements that exist independently of navigational properties outside of that page, e.g., audio sounds, movie clips, or a portable document file (PDF).

A decision point indicates a sequence in the process at which the end user chooses an option, i.e., a "yes-no", or "true-false" response, and then branches to different parts of the flowchart.

Arrows and connecting lines diagram the logical progression through the course, subject to the choices made at decision or action points within the process.

The input/action symbol represents a user response that directs the course flow from that point onwards, i.e., an online test or questionnaire form.

manual input shape

Represents the choice made by the user from mutually exclusive options, e.g., a student choosing among different lesson plans.

Conditional selector is similar to the conditional branch except that the user has the option to choose from a number of paths that will fulfill the requested conditions, e.g., the results of a search engine request.

Pages that share one or more common aspects, and are functionally identical may be simplified as a rounded corner rectangle, such as an on-line test or feedback form.

Annotations provide helpful comments or explanations, e.g. denoting the location where an undeveloped new page/process will fit into the navigational flow structure, or notes for specific team members for further development.

Flow references and flow areas are symbols for reusable sequences, such as logging in with a specific user id and password to enter the course or to initiate an on-line quiz. The flow reference symbol acts as a placeholder for the flow area sequence in the chart in every situation in which it is repeated.

Flow area is used as a flow area. It documents sections that share similar components/repeated steps within that flow, and requires the use of the following two symbols: entry and exit points.

Exit point concludes the subroutines, such as when the proper user id and password are verified, and documents where the user re-enters the master flowchart.

Entry point documents the place within the master flowchart where the process deviates into a subroutine.

Reference is used as a connecting point when the flowchart necessitates using more than one page, or refers to a complicated subroutine that would be impossible to contain on the main flowchart page.

On-page reference indicates that the next or previous step is somewhere else on the flowchart. It is particularly useful for large flowcharts.

On-page reference shape

Off-page reference use a set of hyperlinks between two pages of a flowchart or between a sub-process shape and a separate flowchart page that shows the steps in that sub-process.

Off-page reference shape

Flowchart Shapes: The designers can click this multi-shape to set to any of the following shapes: Data, Document, Decision, or Process. Any text you type onto the shape, or information you add to its Shape Data, remains with the shape.

Document represents a step that results in a document.
