Introduction to Process Flow Charts (Lean Six Sigma)

Summary

This video introduces process flowcharts, a key tool in Lean Six Sigma for process improvement. It explains common symbols used in flowcharts, such as rectangles for activities, diamonds for decisions, and ellipses for start and end points. Swim lanes are introduced as a way to depict who performs each task, distinguishing between parties like warehouse and carrier activities. The video also emphasizes that process flowcharts often need to be supplemented by Standard Operating Procedures (SOPs) to provide more detailed instructions for training and implementation. A free Lean Six Sigma White Belt certification course is also highlighted.

Takeaways

• 😀 Process flowcharts are essential tools in Lean Six Sigma for visualizing and improving processes.
• 😀 The key symbols in process flowcharts include squares (activities), diamonds (decisions), ellipses (start/end), and arrows (directional flow).
• 😀 A diamond symbol represents a decision point with two potential outputs (yes/no).
• 😀 Predefined process symbols represent subprocesses or steps defined elsewhere in the diagram.
• 😀 Documents in the process are represented by a specific symbol to indicate their creation or update.
• 😀 Circular connectors help avoid line crossings, while off-page connectors link different process maps across pages.
• 😀 A high-level shipment process flowchart demonstrates a basic process sequence (pick, check, pack, ship, deliver).
• 😀 Swim lane diagrams help illustrate who is responsible for each step in the process (e.g., warehouse vs. carrier).
• 😀 A macro process map (management view) shows an overview, but varying levels of detail can be included depending on the audience.
• 😀 Standard Operating Procedures (SOPs) are often used alongside flowcharts to provide additional details and training resources for processes.
• 😀 The combination of process flowcharts and SOPs helps ensure that processes are well-understood and efficiently followed.

Q & A

What is the purpose of a process flow chart in Lean Six Sigma?

A process flow chart is used to visualize the sequence of process steps, helping to understand and improve the current state of a process.

What is the significance of understanding the 'as is' state in process mapping?

Understanding the 'as is' state is crucial because it allows us to capture and analyze the current process before implementing improvements.

Which symbols are most commonly used in process flow charts, and what do they represent?

The most common symbols include rectangles (for activities), diamonds (for decisions), ellipses (for start and end points), and arrows (for directional flow).

What does a diamond symbol represent in a process flowchart?

A diamond represents a decision point in the process, with Yes and No outputs leading to different paths.

How are subprocesses or steps defined elsewhere represented in a process flow chart?

Subprocesses or steps defined elsewhere are represented by a predefined process symbol, which shows that the detailed steps are located in a different process map or document.

Why might an off-page connector be used in a process flow diagram?

An off-page connector is used to connect process steps that appear on different pages, ensuring that the flow is not interrupted by page breaks.

What is a high-level process map, and how is it different from a detailed process map?

A high-level process map, also known as a macro process map, provides a broad overview of the process, while a detailed process map breaks down each step for deeper analysis.

What is the purpose of a swim lane diagram, and how does it improve understanding of a process?

A swim lane diagram separates the process into lanes based on the parties involved (e.g., warehouse or carrier), making it clear who is responsible for each step.

Why might a standard operating procedure (SOP) be necessary alongside a process flow diagram?

An SOP provides more detailed information on the process, such as background, purpose, specific steps, and references to related documents, which are needed for effective training.
