Block Diagramming / Flow Charting

Block diagrams are high-level flowcharts utilized in engineering for designing and enhancing systems.
They illustrate major system components, key process participants, and important interactions.
Blocks in a diagram represent significant parts of a system, assisting in understanding the system’s interface and structure.
There are five types of block components: Block, Part, Reference, Standard port, and Flow port.

Types and Uses of Block Diagrams

Block diagrams offer a quick overview for identifying points of interest or trouble within a system.
They focus on the input and output of a system while disregarding internal processes, known as the "black box" principle.
Unlike circuit diagrams, block diagrams do not detail every wire or switch, focusing instead on the overall structure and flow.

Making a Block Diagram

Block diagrams can be created similarly to flowcharts with rectangular blocks representing critical points in a system.
Lines connecting blocks indicate relationships and flow, with arrows in electrical contexts representing signal direction.
Details can be added as needed using specific electrical schematic symbols to enhance the diagram's clarity.

Best Practices for Block Diagrams

Identify the system to be depicted, defining its components, inputs, and outputs.
Create and label the diagram with symbols for each component, indicating flow direction with arrows.
Ensure clarity by labeling inputs and outputs and verifying accuracy with stakeholders involved.

Flowcharts

A flowchart is a graphical representation of steps, initially developed in computer science for depicting algorithms.
They visualize complex processes and clarify the structure of problems or tasks.
Flowcharts define processes or projects, aiding documentation, study, planning, improvement, and communication in various fields.
They are recognized for effectively conveying often complex information in an easy-to-understand manner.
