What is a Block Diagram?
Block diagrams are high-level flowcharts used to design new systems or to describe and improve existing ones. It has a specialized structure that provides a high-level overview of major system components, key process participants, and important working relationships. Block diagrams are commonly used by people who need to understand, analyze and communicate complex systems, such as engineers, scientists, managers, educators and many others.
How to Create a Block Diagram Collaboratively on Creately?
- Create your workspace
Begin by opening a Creately workspace. Add your team as collaborators to work together with them on the same workspace. You can use real-time mouse cursors and synced previews to easily track the changes other participants make in the workspace.
- Gather information
Collect all the necessary information about the system or process, including inputs, outputs, and the functions or processes that transform the inputs into outputs. As the team brainstorms, add the ideas using sticky notes on to the canvas.
- Create a rough draft
Use Creately’s purpose built shapes, such as rectangles or circles, to represent the main components of the system or process. Use the Plus Create feature to easily connect shapes with arrows to indicate the flow of data.
- Add text and annotations
Identify and label your inputs and outputs- this refers to the starting points of a process and the resultant action that occurs along the way.
- Organize and align the components
Use layout and alignment tools to arrange the components in a clear and organized way. Choose colors, fonts, and line styles that make the diagram easy to read and understand.
- Review and finalize
Review the block diagram for accuracy and completeness. Make any necessary changes and finalize the diagram. Share the diagram with others, such as team members, and receive feedback and suggestions for improvements with contextual comments right on the diagram itself.

FAQs about Block Diagrams
- Identify the system which you want to illustrate. Before starting to draw the diagram, define its components, inputs and outputs.
- Include proper labels. Add labels to every block so that those are easily identified. Make sure you add symbols for each component of the system and indicate their flow with connected arrows.
- Clearly indicate the inputs and outputs. It is important to label inputs that activate blocks and outputs that end blocks.
