What This Course Covers

Data Collection and Prioritization

• Design intuitive Check Sheets that eliminate user error in high-pressure environments like hospital emergency rooms.
• Apply the 80/20 rule using Pareto Charts in Microsoft Excel to separate vital problems from trivial ones.
• Analyze the Armand Pharma leakage crisis as a real-world example of data prioritization.
• Master the art of collecting raw data and transforming it into actionable visual intelligence.

Structured Root Cause Analysis

• Utilize Fishbone (Ishikawa) Diagrams to explore potential root causes of operational failures.
• Implement the 6M framework (Manpower, Method, Machine, Material, Measurement, Mother Nature) for comprehensive analysis.
• Apply the 4P framework (Policies, Procedures, People, Plant) to structure organizational problem-solving.
• Use Microsoft Visio to create professional root cause diagrams for executive presentations.

Statistical Process Control and Variation

• Decode frequency distributions and interpret bimodal patterns using Histograms.
• Compare process capability against customer specification limits to ensure quality standards.
• Master the use of Control Charts (SPC) including Center Lines, Upper Control Limits (UCL), and Lower Control Limits (LCL).
• Distinguish common-cause variation from special-cause variation to prevent unnecessary process tampering.

Correlation and Relationship Mapping

• Plot paired continuous variables using Scatter Diagrams to visualize data trends.
• Calculate R² trendlines in Microsoft Excel to determine the strength of relationships between variables.
• Learn to avoid the dangerous analytical trap of assuming correlation equals causation.
• Apply relationship mapping to identify the primary drivers of quality defects in a production line.

Process Mapping and Workflow Optimization

• Create detailed Flowcharts to map current-state and future-state operational workflows.
• Identify hidden operational delays and bottlenecks through visual process analysis.
• Implement the Gemba Walk methodology to observe actual work processes in their real environment.
