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.

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.

  1. 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.
