Questions and Answers

What are some characteristics of Six Sigma?

It reduces the number of errors in a process by minimizing variation, the six sigma metric equals 3.4 defects per million opportunities, 99.9997% defect-free, charts process performance against a mean measurement.

What types of activities does the Lean methodology focus on?

Streamline and improve processes, eliminate waste, identify and add value.

What are some benefits of implementing Six Sigma?

Better understanding of key financial drivers, improved organizational cultures through inclusion and collaboration, increased customer satisfaction.

Which questions will help assess whether an organization is ready for Six Sigma?

Does the organization have a clear vision for the path it wants to take in the future? Will the cost of implementation outweigh the benefits? Are our current improvement approaches and change management structures sufficient? Is change a critical business need now? Signup and view all the answers

In which situations is Kanban-pull being used?

An automated e-mail message is sent to a glass company when supplies at a bottling company are getting low. A light in the paper room flashes when more paper is required in the print room. When a bin of to-be-processed applications has three left in it, clerks signal for more to be added. Signup and view all the answers

Study Notes

Six Sigma Characteristics

Reduces errors by minimizing process variation.
Achieves a metric of 3.4 defects per million opportunities.
Ensures 99.9997% defect-free performance.
Charts process performance against a mean measurement.

Lean Methodology Focus

Streamlines and improves operational processes.
Eliminates waste to enhance efficiency.
Identifies and adds value to processes.

Benefits of Implementing Six Sigma

Enhances understanding of key financial drivers in operations.
Fosters improved organizational culture through inclusion.
Increases customer satisfaction by meeting expectations.

Assessing Organizational Readiness for Six Sigma

Clear vision for future goals is necessary.
Implementation costs should not outweigh potential benefits.
Current improvement and change management structures must be adequate.
Change must be a critical business need, addressing bottom-line or competitive pressures.

Kanban-Pull Situations

Automated notifications trigger when supplies at a bottling company run low.
Lights signal for replenishment in the paper room when existing supplies are low.
Clerks request additional applications when quantities fall below a threshold.
Empty containers are systematically sent for replenishment in supply areas.

Potential Value of Six Sigma

A customer-centric approach leads to increased satisfaction over time.
Improved process quality can enhance net profits over time.

Activities Classification

Value Adds: Legal personnel preparing contracts.
Waste: Excess handling of parts in assembly.
Nonvalue Adds: Inefficient reviews of each line of code in software development.
Value Adds: Catering companies charging more for delivered meals.

Key Principles of Lean

Maximize customer value throughout processes.
Actively reduce waste across the entire value stream.
Focus on improving efficiency, quality, and customer satisfaction.

Questions for Integrating Lean and Six Sigma

Evaluate the organization's capacity for cultural change.
Assess the extent of existing problems to be addressed.
Identify foundational issues to be resolved.
Consider constraints regarding time and financial resources.

Evolution of Continuous Improvement Methodologies

First: Plan, Do, Check, Act (PDCA) cycle.
Second: Statistical Process Control (SPC).
Third: Introduction of Quality Circles.
Fourth: Establishment of ISO 9000.
Fifth: Adoption of The Baldridge Criteria for Performance Excellence.

Information from Value Stream Mapping

Detailed overview of activities involved in product or service creation.
Identification of potential waste in processing.

Specific Goals of Six Sigma

Aim to lower overall operating costs of the organization.
Strive to improve customer satisfaction levels.

Characteristics Comparison of Six Sigma and Lean

Both: Significant savings, systematic problem-solving, implementation by teams, inspired by PDCA.
Six Sigma: Utilizes DMAIC methodology, focuses on reducing variation, employs statistical tools.
Lean: Implements Kaizen principles, focuses on reducing waste, employs value stream mapping.

Benefits of Six Sigma Implementation
