Lean Six Sigma

Lean Six Sigma combines the best of two proven-successful process improvement methods—Lean and Six Sigma—to help organizations achieve their missions as fast and efficiently as possible. Lean focuses on the elimination of waste, while Six Sigma focuses on minimizing variation and detecting and removing causes of error. Both methods were born in manufacturing settings, but the combined framework of Lean Six Sigma can be used in any industry, including information technology, healthcare, finance, human resources, accounting, hospitality, transportation.

Ultimately, Lean Six Sigma improves your organization’s bottom line, provides value to your customers, engages your team members and employees and transforms your organizational culture.

Our courses will give you a solid foundation in Lean Six Sigma methodologies and specific exercises to hone the analytical, problem-solving and leadership skills you need to support successful improvement projects. On an individual level, Lean Six Sigma certification can help you advance your career, demonstrating to your employer (or future employers) that you have a highly-prized and internationally-recognized skill set and that you are serious about continuous improvement.

Each week in this series will cover a different but inter-related topic:

Accelerating the Flow of Work

The creation of valuable products and services must not be slowed down by wasteful practices, interrupted by bottlenecks or fragmented by department silos. What gets in the way of smooth fast defect-free work? How many of our efforts are wasteful? Realize the impact of non-valuable work and learn to challenge the current state of operations.

Improving the Work Everyday

When dealing with production problems, the last thing you want is the same issue to show up repeatedly. Where should you making improvements when everything seems urgent? How to improve operations and personnel performance? Will small changes make a difference? Learn to solve problems for good and sustain high levels of performance.

Measuring Work Results

To run an efficient operation you must know how well you are fulfilling customer needs, how inputs are transformed into outputs, and which are the biggest defects and cost drivers. Who do we work for and which results are important? What is the relationship between results, processes and inputs? Learn to identify your most important process variables and zero in on your most urgent problems.

Solving Problems in Operations

The ability to make decisions rapidly and across the production line is necessary to quickly respond to any changing conditions in production What should we do when we spot a problem? Escalate or take action? How do we learn more about our operations every day? Learn the methods used by Toyota to nip problems in the bud.

Lean Data works in any business sector and can be spearheaded by any department—marketing, advocacy, engineering, production, design, compliance, privacy, legal, and customer support, to name just a few. You don't need a technical degree or a dedicated budget. All you need is a commitment to making data decisions thoughtfully.

Each week in this series will cover a different but inter-related topic:

Getting Smart with Numbers

An operation cannot be controlled or improved when you lack the right indicators and an intuitive way to display them clearly. How do you know what to measure? By what method? How frequently, precisely? Learn how to use data to measure the performance of your operations.

Managing Variation

Process performance changes all the time, which can create confusion, and worse, inaction in the face of a negative event or trend. So what does it mean when a metric is higher or lower than last week? Can you tell whether a change is significant? Learn how to distinguish between random changes and a signal to action.
