What the Lean Six Sigma methodology is
The Six Sigma methodology was born in 1986 in the United States, more precisely in Motorola, with the aim of significantly reducing defects within the production processes, ideally to have only 3.4 defects per million opportunities (99.99966% of expected parts without defects!). In statistical language, this means having a process in which the standard deviation (indicated with the Greek letter sigma) is the twelfth part of the tolerance range of a dimension, or +/- 6 sigma, hence the name of the methodology.
The Six Sigma essentially makes use of a series of statistical tools already used for several decades in the field of quality control in the American manufacturing industry, formalizing a structured process in 5 steps (DMAIC), based on the Plan-Do-Check process. Deming Act. This process consists of the following steps:
- DEFINE: the problem to be faced is defined and circumscribed
- MEASURE: the quantitative metrics (or metrics) on which to work are appropriately measured (reduction of defects, reduction of the variability of cycle times, etc.)
- ANALYZE: the problem is analyzed and possible causes are identified
- IMPROVE: identified the cause, a possible improvement action is tested
- CONTROL: the effect of the implemented action is monitored and the results verified
The term Lean, on the other hand, identifies the set of methodologies deriving from the Toyota Production System with the aim of reducing waste within the processes. In this case, the tools used are not statistical.
Therefore, Lean Six Sigma is an improvement philosophy based on real data and observations, which is based on the prevention of the defect rather than on its detection, it is responsible for customer satisfaction thanks to the reduction of variability and waste within the processes and promotes the use of standardization and value streams thereby creating a significant competitive advantage.

Lean Six Sigma, therefore, is a philosophy of improvement based on real data and observations, which is based on the prevention of the defect that, on its life, is responsible for customer satisfaction thanks to the reduction of variability and waste within the processes and promotes the use of standardization and value streams thereby creating a competitive advantage.
Support for Lean Six Sigma Projects
Lean Six Sigma projects are necessary in the presence of particularly complex problems, or when the cause is not clear or how to solve them effectively, or in a statistically significant way.
Accialini Training & Consulting is able to provide you with a professional with proven many years of experience in the implementation of the indicated methodologies and with Black Belt certification.
This professional will then be able to give you the necessary support in the following stages:
- Implementation of a data-driven decision-making culture in order to identify priority improvement projects
- Management of continuous improvement projects, from problem definition to implementation and control
- Mentoring and coaching of the continuous improvement team
Lean Six Sigma Certifications
For the methodology to be effective, it is important that employees are properly trained. As in Japanese combat disciplines, in fact, each color is associated with a certain level of knowledge on the Lean Six Sigma methodology:
The White Belt Certification provides the professional with a basic knowledge of Six Sigma fundamentals and their application and is recommended for any employee of a company in which the Six Sigma methodology is applied.
The Yellow Belt certification is issued to employees who have basic training in Six Sigma quality improvement methodology and participate in related projects.
Green Belts are professionals who work closely with Black Belts. A Green Belt can also fill minor leadership roles within a Six Sigma team, particularly for small-scale projects. They are well trained in the proper use of Six Sigma tools and employ them under the direction of a Black Belt project leader.
Black Belts are considered the leaders within a Six Sigma team. Their main task is project management. It is their job to set goals and timelines for the project, as well as constantly update managers and stakeholders on the current state of the business. In addition, they often display excellent communication skills and assume the role of “change agent” within their organization.
Master Black Belts play a very important role within a Six Sigma organization. They are the experts at the top of the hierarchy of trained and certified Six Sigma professionals. With their level of experience, skills and knowledge, they can act as consultants of this methodology.
We offer support for the White Belt, Yellow Belt and Green Belt certification. We are in fact accredited by Council for Six Sigma Certification, an internationally recognized certification standard. Furthermore, our training courses are in line with the ISO 13053-1: 2011 standard.

Lean Six Sigma implies the use of a series of tools thanks to which the Team is able to manage improvement projects, using each time the best tool (often of a statistical nature) to achieve the desired goal (reduction of waste and process variability). The Lean Six Sigma Toolkit consists of a collection of tools, mainly in Excel, thanks to which it is possible:
- practice the methodology in the learning phase
- put the methodology into practice without the need to purchase expensive licenses for dedicated software
- share the results within the company thanks to the standardization of tools
