What Is a Flowchart? A diagram that uses graphic symbols to depict the nature and flow of the steps in a process. FLOWCHART VIEWGRAPH 1
Benefits of Using Flowcharts • Promote process understanding • Provide tool for training • Identify problem areas and improvement opportunities • Depict customer-supplier relationships FLOWCHART VIEWGRAPH 2

Interpreting Your Flowchart • Determine who is involved • Form theories about root causes • Identify ways to simplify and refine • Determine how to implement changes • Locate cost-added-only steps • Provide training FLOWCHART VIEWGRAPH 12
Interpretation Steps Step 1 - Examine each process step Bottlenecks? Weak links? Poorly defined steps? Cost-added-only steps? Step 2 - Examine each decision symbol Can this step be eliminated? Step 3 - Examine each rework loop Can it be shortened or eliminated? Step 4 - Examine each activity symbol Does the step add value for the end-user? FLOWCHART VIEWGRAPH 13
