Simplify describing complex processes or algorithms by creating a flowchart.

Diagrams have always been a wonderful medium to understand and manage complicated tasks. And when it comes to the flowchart, there are numerous things it has to offer.

From clearly presenting the perfect picture of any process to inspecting to establishing the standards for quality and efficient working, it helps in the smooth functioning of all the processes.

Not only this, further it helps in communicating the whole process with the team. And assists in locating unrequired steps and bottlenecks that help in upgrading the work.

Isn’t it so much helpful?

Yes, it is!

So, let’s dive deeper into flowcharts and see how to create one.

What is a flowchart?

A flowchart refers to a diagram that portrays any process or algorithm, from top to bottom or right to left, in steps. It illustrates the whole work in small tasks and comes to an end with a solution or end of the process. It can be drawn on paper as well as digitally with the help of any software.

It’s like a virtual map for your journey through a process that makes the path easy to understand.

Many authors have categorized the flowcharts by making their own bases. For instance, Sterneckert has classified the charts based on “Flow Control”. According to him, flowcharts are of 4 types.

They are:

  • Document Flowcharts,
  • System Flowcharts,
  • Data Flowcharts, and
  • Program Flowcharts.

Likewise, there are many types in the flowcharts on other bases.

So, how does it help to understand things easily?

A flowchart helps in understanding difficult processes in one go by simplifying the workflow or algorithm. It provides a perfect picture of any complex process. And help in tracking what has been done, what to do next, and what is pending.

One can easily analyze the situation and follow it for ensured and desired results. And ultimately, it provides a pre-defined conclusion at the end of a particular scenario.

It displays the whole process in different shapes for different types of steps. Since the steps in a chart can be some action, decision making, documentation, input/output, wait or delay, etc. So, there is a corresponding shape for all types of steps. These are not the hard & fast rules, but some global standards to make these accessible by everyone.

For instance, if a step involves some decision making, you need to use a rhombus shape. And this is how you have various shapes for various types of steps. And the arrows work as a path to show the order of steps. There are many appealing shapes for the steps, such as rectangle, rhombus, oval, etc.

Prominent shapes and their use in the flowchart

The different shapes were created eventually to define the types of steps. And there are numerous shapes for different flowcharts and their steps. Some prominent and frequently used shapes are as follows:

  • Terminator – It is in an oval shape for starting & ending points. It is also used for the result/outcome of some path in the chart.
  • Decision – It gives two boxes that result from “Yes” and “No” answers to the decision. In computer algorithms, it can be understood by “if-else” statements used to compare and produce binary outputs.
  • Process – A rectangular-shaped symbol is used frequently for some definite action or function in the process. There may be single steps in these boxes, or you can include more than one continuous step together.
  • Document – This shape is inserted while getting any document for input. For instance, receiving letters, emails, orders, etc. When some document is available for the output of data or order, this symbol is in use. Examples of documents available for output are creating a memo, letters, etc.
  • Data (Input/Output) – The rhomboid shape in the diagram denotes some data available for input or output in the process.
  • Pre-defined Process – It represents some familiar process or a process that is defined somewhere else. Additionally, it can be used for some complex processes. It’s not necessary to include these in the flowchart, but one can use them to understand any process’s internal functioning.
  • Manual Input – As the name suggests, it refers to the input of data physically by someone. Normally, the input of data is done through some gadget or tool.
  • Delay – This symbol is for the delayed work in some part of the process. You can also mention the delayed time-period within the D box for a clear depiction.
  • Comment or Annotation – The comment symbol is in use when any step requires some additional information. This symbol is in braces with the required text. It can also have a dashed line connected with a specific section of the flowchart that requires explanation.
  • Database – It is in a cylindrical shape used when some data is stored in a storage service.
  • On-page Connector – An On-page connector is a small circle that links different elements on the same page to avoid confusing and cluttered meshes.
  • Off-page Connector – It helps in linking the different elements on separate pages. For some complex processes, you sometimes may need to create long enough flowcharts to cover several pages. In that case, these off-page connectors make things easy.

Besides computer algorithms, they are widely used in other fields such as business, manufacturing, education, engineering, sales, and marketing. They encompass every possible area of a process in these fields. And give a full backup from beginning to end.

So, before creating one for yourself, let’s look at some popular use-cases of flowcharts.

Efficient computer algorithms

Flowcharts are proved to be the most helpful in developing efficient computer algorithms. Since they help understand the complicated issues, they can feature the whole idea to create an effective logical solution as algorithms. So, it helps in communicating, discussing, analyzing the algorithms as well.

Planning new projects

Many people in a team generally work on new projects frequently. So, flowcharts prove to be very helpful while planning them. Most probably, they help in effectively portraying the steps needed to complete the whole project.

Auditing the Processes

In addition to giving a clear picture of the work, flowcharts are efficient enough to spot the process’s issues. When the whole work is split into small steps connected sequentially, it helps identify unnecessary things and allows making improvements. This saves time and ensures a smooth workflow.

Managing Workflow

Workflow diagrams (a type of flowchart) are in use for managing workflow. Managing the workflow may target either the direction of human work or integration of processes, or both.

The processes are set in the best way that results in the most effective and efficient output at the end.

Modeling Business Processes

Flowcharts are beneficial for documenting business processes. These processes can be very typical, with many possibilities or results in the end. So, flowcharts can make things certain and give a proper direction for them. Notably, a unique type of diagram is in use that is an “event-driven process chain” (EPC) diagram for business processes.

Decision making 🤔

Flowcharts can show all the possible choices to make the decision-making process fast, data-driven, and easy. Actually, flowcharts give direction to your decision making thoughts. Ultimately helping you to make decisions faster.

Now, let’s look at some smart flow chart makers.

Miro Flowchart
