What is a Flowchart? 

Flowcharts are visual diagrams that represent a process, workflow, or system by using symbols, arrows, and lines to illustrate the sequence and relationships between tasks. It simplifies complex processes by breaking them down into individual steps, allowing for better understanding and analysis. 

Flowcharts are widely used across industries to document procedures, plan projects, make decisions, or streamline operations. They make it easier to communicate ideas clearly and identify inefficiencies or bottlenecks. Whether in Project Management, Software Development, or business operations, flowcharts provide a clear and structured way to map out processes visually.
 

 

The Importance of Flowcharts 

Flowcharts are widely used in multiple fields, from engineering to business, because they: 

a) Simplify Complex Processes: By breaking down workflows into smaller, manageable steps, flowcharts enable you to visualise the whole process in a clear, structured way. 

b) Enhance Communication: Flowcharts offer a universal language that simplifies Communication between departments, especially when collaborating on complex tasks. 

c) Support Decision-making: They help organisations make informed decisions by mapping out various outcomes and paths. 

d) Increase Efficiency: Flowcharts identify bottlenecks, inefficiencies, and unnecessary steps in processes, making it easier to streamline workflows.
