• Overproduction – making more than is needed
• Waiting – delays between process steps or due to materials, approvals, or equipment
• Transport – unnecessary movement of materials or products
• Overprocessing – doing more work or using more resources than required
• Inventory – excess raw materials, work-in-progress, or finished goods
• Motion – inefficient movements by people or equipment
• Defects – rework, scrap, or quality issues
• Underutilized talent – failing to engage employees in problem-solving or improvement
• Conduct waste walks, kaizen events, and root cause analysis workshops to uncover waste and implement countermeasures.
• Deploy visual management systems, 5S, and workplace organization tools to sustain waste reduction.

Industrial Engineering & Productivity Optimization:

• Conduct line balancing, time studies, and workflow analysis to improve throughput and optimize labor allocation.
• Analyze resource utilization and develop staffing models based on takt time, cycle time, and demand.
• Design and implement standard work instructions to improve consistency and reduce process variability.
• Improve equipment changeover times using SMED (Single-Minute Exchange of Die) techniques.
• Evaluate plant layout and material flow, recommending changes to reduce transportation and motion waste.
• Lead productivity improvement projects to increase overall equipment effectiveness (OEE) and reduce downtime.

Continuous Improvement & Problem Solving:

• Lead cross-functional problem-solving efforts and coach teams on structured Root Cause Analysis (RCA) tools such as:
• 5 Whys
• Fishbone (Ishikawa) diagrams
