Study Notes

Lean Six Sigma Training and Certification overview

Green Belts are trained to independently manage Lean Six Sigma projects with guidance from Master Black Belts.
They are expected to be familiar with statistical tools for Lean Six Sigma projects.

Roles and Responsibilities

Green Belts:
- Manage projects independently with guidance from Master Black Belts
- Have familiarity with statistical tools
Master Black Belts:
- Can lead complex projects with durations potentially exceeding 6 months
- Expected to have higher probability of achieving hard and soft savings or efficiencies

Lean Six Sigma Project Levels

Scope: Projects can range from sub-process improvements within a team to cross-functional process improvement across multiple teams
Complexity: Complexity increases with each project level
- Sub-Process improvement: Low-Med complexity
- End-to-end process improvement: High complexity
- Cross-functional process improvement: Very High complexity
Duration:
- Sub-Process improvement: 3 - 6 months
- End-to-end process improvement: 6 months avg
- Cross-functional process improvement: Can be longer than 6 months
Savings:
- Sub-Process improvement: High probability of soft savings and effort reduction
- End-to-end process improvement: Probability of hard and soft savings
- Cross-functional process improvement: High probability of hard savings and efficiencies
Leadership:
- Sub-Process improvement: Can be led by a potentiated employee
- End-to-end process improvement: Must be led by a team leader or manager
- Cross-functional process improvement: Must be led by a Black Belt or Master Black Belt

Traditional vs. Lean Thinking

Traditional: Cost + Profit = Selling Price
Lean: Profit = Selling Price - Cost. This emphasizes minimizing costs to maximize profits.

Value vs. Waste

Value Adding: Activities that transform inputs, meet customer needs, and create value.
Value Enabling (Necessary Waste): Activities required by regulations or for compliance. These activities do not directly add value but are necessary.
Non-Value Adding (Waste): Activities that do not add value to the product or service. These activities should be minimized or eliminated.

8 Types of Waste

Defects: Efforts to rework, scrap, or correct errors.
Overproduction: Producing more than needed or before needed.
Waiting: Wasted time during the process before the next step can be taken.
Non-Utilized Talent: Failing to use employees' skills, knowledge, and talents.
Transportation: Unnecessary movement of products or materials.
Inventory: Producing excess products or materials.
Motion: Unnecessary movement by people performing tasks.
Extra-Processing: Producing higher quality or doing more work than the customer demands.

Common Misconceptions About Lean

Lean is only for manufacturing companies.
Lean is costly and time-consuming.
Lean has a high focus on process efficiency.
Lean will eliminate jobs.
Lean is a one-time event.
Lean is the same as Kanban or Kaizen.
Lean relies on Toyota's tested process tools.
Lean is effective only in companies with a continuous improvement culture.

Six Sigma Principles

Customer Focus: Customer needs should be the primary focus.
Understanding Work Processes: How work flows should be understood.
Streamlined Processes: Processes should flow smoothly and be optimized.
Waste Reduction: Waste should be eliminated and value should be maximized.
Defect Elimination: Variation should be minimized to prevent defects.
Collaboration and Buy-in: Teamwork is essential.
Scientific Approach: Approaches should be systematic and based on data.

Fundamental Equation of Six Sigma: Y = f(x1, x2, x3, ... xn)

Y = Dependent Output (what you want to improve)
f = Function/Process
X = Independent Inputs (factors impacting the output)
The equation emphasizes that to improve outputs (Y), one needs to understand the process (F) and identify how inputs (X) influence the output.

Accuracy vs. Precision

Accuracy: Closeness to the desired target value.
- Example: Shooting at a target with most shots clustered near the center.
Precision: Consistency of repeated measurements.
- Example: Shooting at a target with all shots clustered together, but not necessarily near the center.
