As to be eligible for the Lean Black Belt certification, the individuals should have completed the Lean Green Belt certification, and when they enter the highest level,  Lean Black Belt certification, they already have knowledge about the 8 types of waste (transportation, inventory, motion, waiting, overproduction, overprocessing, defects, and unused talent) and how to identify and eliminate them from the production process, organising and maintaining a clean, efficient, and safe workplace, with 5S concept ( Sort, Set in Order, Shine, Standardize, and Sustain), Gemba Kaizen philosophy of continuous improvement, which involves making small, incremental changes in the production process to achieve significant improvements in quality and efficiency.

They also know how to map out the production process and identify areas of waste and inefficiency, as well as opportunities for improvement. Further, the participants also know how to track and measure key performance indicators (KPIs) to monitor the progress of lean initiatives and identify areas for further improvement, how to use visual management tools to communicate information clearly and effectively, including the use of visual pyramids to prioritise improvement initiatives. Along with that, they have learnt a range of basic lean problem-solving techniques, such as Root Cause Analysis, Fishbone Diagrams, and 5 Why’s. Not only that, they also have insight into the 8-Step Problem Solving process, which involves defining the problem, containing the problem, identifying the root cause, developing and testing solutions, implementing the solution, verifying the effectiveness of the solution, standardising the solution, and celebrating success.

In Lean Black belt certification, all of the above are taught and revised before providing the knowledge on the newest techniques and methodologies used in Lean management.

Some of the new main techniques and methodologies taught in Lean Black belt certification

01. Yamazumi and Layout Preparation

A process improvement tool called Yamazumi is used to analyse and balance workloads. It is a visual tool that aids in locating locations where workload distribution is uneven and suggests areas for improvement. Yamazumi charts are used to display the amount of work being done by each employee or piece of equipment and to pinpoint areas where changes can be made to better balance the workload. On the other side, layout preparation is a strategy used to optimise the physical arrangement of a work area in order to increase productivity and decrease waste. It entails examining the movement of people, equipment, and materials in a workspace and rearranging them in a way that avoids unnecessary movement, cuts down on the distance that materials must go, and enhances the flow in general.

By becoming certified as a Lean Black Belt, professionals can show their expertise in using these and other tools to identify and eliminate waste, reduce variation, and improve overall process efficiency.

02. JIT and Multiskilling

A manufacturing strategy known as “Just-in-Time” places emphasis on creating things just when they are required and in the quantities required in order to minimise waste and lower inventory costs. Production process simplification, shorter lead times, and higher-quality products are all benefits of JIT.

Training staff members to do various activities or responsibilities as part of a process or organisation is known as multiskilling. Organisations can boost flexibility and efficiency and lower the risk of interruptions brought on by personnel shortages or absences by cross-training their employees.

These methods are crucial tools for improving processes and are frequently included in Lean Black Belt certification training. Individuals can demonstrate their proficiency in applying these and other methods to find and remove waste, reduce variance, and increase efficiency by earning a Lean Black Belt certification.

03. 5-Day Kaizen Activity

To make major advancements quickly is the aim of the 5-Day Kaizen Activity. The activity can result in quick and long-lasting outcomes by using an organised approach which includes defining the scope of the improvement project, mapping the current process, analysing the data, developing and implementing solutions and finally, monitoring and controlling and also with a cross-functional team. The 5-Day Kaizen Activity and other process improvement activities can be conducted and facilitated by individuals who have earned their Lean Black Belt certification.

04. Safety & Ergonomics

Every process improvement endeavour should take ergonomics and safety into account, and lean black belt certification emphasises these concepts. A Lean Black Belt is taught to recognise and address any ergonomic and safety risks that may develop during a process.

The identification, evaluation, and development of solutions to safety and ergonomic problems are all included in the Lean Black Belt certification program. This entails identifying potential risks and hazards, assessing how they might affect workers, and devising and putting into practice strategies to reduce or eliminate those risks.

To create a safer and more productive workplace, safety and ergonomics are integrated into the lean process. Organisations can build the skills and knowledge required to successfully identify and address safety and ergonomic issues by training people for Lean Black belt certification.

05. Assembly-line simulation

An important result of receiving a Lean Black Belt certification is assembly-line simulation. It is a technique for enhancing manufacturing procedures that simulate the production line. The assembly-line simulation aims to spot manufacturing process bottlenecks and other inefficiencies and develop methods to get rid of them.

To find possible problems, assembly-line simulation entails building a virtual representation of the production process and putting it through various scenarios. This can involve experimenting with various assembly line configurations, modifying the production line’s pace, and switching around the sequence in which activities are completed.

A Lean Black belt holder can anticipate possible issues before they arise and create solutions to boost production efficiency by employing assembly-line simulation.

06. Chassis model and PCU

The Lean Black Belt certification offers specific knowledge related to process improvements in the automobile industry, such as the PCU and chassis model. The term “chassis model” refers to a representation of the vehicle’s frame that is used to spot any inefficiencies or waste throughout the production process. The manufacturing process is simulated using the chassis model, which helps find possible problems before they arise during actual production.

In the manufacturing of automobiles, the PCU (Process Control Unit) is a control system that makes sure the production process is running within the specified bounds. The PCU gathers information from numerous sensors and other sources during the production process and gives operators and management real-time feedback.

The PCU and the chassis model are both crucial tools for enhancing the effectiveness and calibre of the manufacturing process in the automotive sector. Moreover, organisations can enhance productivity, quality, and cost savings by using the chassis model to spot possible problems and the PCU to manage the production process.

Individuals are taught how to use these tools by Lean Black belt training programs to locate possible waste, inefficiencies, and flaws in the manufacturing process. In order to ensure that the improvements are maintained throughout time, they are also taught how to create and put into practice solutions to deal with these problems as well as how to oversee and manage the manufacturing process.

07. Lean Leadership

One of the main benefits of earning a Lean Black Belt is Lean Leadership. Through the application of Lean principles and practices, the certification process focuses on providing individuals with the knowledge, abilities, and resources needed to lead and drive organisational change.

Successful Lean projects require strong leadership since it requires handling change well, gaining stakeholders‘ support, and fostering a culture of continuous improvement. In order to implement change and foster a culture of continuous improvement inside an organisation, the Lean Black Belt certification places a strong emphasis on the development of leadership abilities like coaching, team building, and communication.

08. Hijunka

Hijunka is a Lean management method that entails distributing workloads or production over a predetermined period to lessen variability and boost productivity. The Japanese word for “levelling” or “standardising” is where the English word hijunka originates.

Hijunka’s major objective is to lessen waste that arises from changes in workloads, demand, or production. Instead of having certain elements of the system overworked while others are idle, this is accomplished by balancing the workload among various processes, devices, and teams. Lean Black belt holders are capable of using this concept instead of having to deal with unexpected spikes and drops in demand, as the goal is to establish a consistent and predictable flow of labour.

09. BIQ and M&I flow mapping

The Business Impact Quotient (BIQ) and M&I (Material and Information) flow mapping are two important techniques in Lean management that are used for process optimisation and waste reduction.

The BIQ metric is used to measure how much an individual business process affects overall business performance. Evaluating a process’s contribution to revenue creation, cost savings, or an increase in customer satisfaction can determine a process’s financial impact. Organisations can target their efforts on areas that have the most effects on business performance by concentrating on high BIQ processes.

M&I flow mapping is a method for illustrating how information and materials move through a process. It aids in locating wasteful activities, including needless waiting, overproduction, excess inventory, faults, and overprocessing. Organisations can streamline their procedures, save lead times, and increase overall efficiency by locating and removing these wastes if they have Lean Black belt certified professionals.

10. Quality support Metrix

An organisation’s quality support systems are evaluated for efficacy using a set of performance indicators called quality support metrics. Customer satisfaction, defect rates, and the frequency and speed of problem resolution are a few examples of the metrics that are often included.

A Lean Black Belt certification’s application of quality support metrics is a crucial learning outcome since it enables individuals to better understand how to assess the efficiency of their organisation’s quality support systems and pinpoint areas for development. Lean Black Belt certified experts can assist their firms in identifying and resolving quality-related problems and improving overall performance and customer experience by measuring and evaluating these indicators.

11. Built-In Quality Simulation

Lean Management uses the technique of Built-In Quality Simulation to assist in finding and fixing quality problems at the beginning of the product development process. In this simulation, a product prototype is built and tested for quality faults before going into production.

A culture of quality is fostered within the firm by the Built-In Quality Simulation, making it a useful tool for lean management. The company can save expensive rework, lower the likelihood of customer complaints, and prevent product recalls by identifying quality issues early in the product development process with Lean Black belt certified experts. Through the provision of high-quality goods that meet or surpass client expectations, this strategy also contributes to an increase in consumer satisfaction.

12. Automation

Automation is the practice of using machinery and technology to carry out operations that were previously handled by humans. Automation can be utilised in the context of Lean management to decrease waste, increase process efficiency, and minimise errors.

As a result, a Lean Black belt certification’s application of automation outcome is crucial since it enables workers to find opportunities to automate operations within their firm in order to increase productivity and reduce waste. Organisations can free up personnel to concentrate on higher-level tasks that need creativity and critical thinking by automating repetitive or low-value jobs. Automation can also speed up processes and decrease errors, improving overall effectiveness and customer satisfaction.

13. Digitization Industry 4.0

Industry 4.0’s term “digitalisation” describes the incorporation of cutting-edge digital technologies into industrial processes to produce smarter and more effective systems. These technologies include the Internet of Things (IoT), Artificial Intelligence (AI), Robotics, Cloud Computing, and Big Data Analytics. It is motivated by the need to boost quality, quicken innovation, and lower costs while increasing productivity.

The goal of the Lean Black Belt certification program is to train professionals in the concepts and methods of the Lean methodology, which aims to cut waste and boost productivity in manufacturing and other business operations. Continuous improvement, standardisation, and the abolition of non-value-added operations are key components of the Lean methodology.

In the context of Industry 4.0, the outcome of Lean Black Belt certification is the development of people who are adept at using Lean concepts and technologies for digitalisation activities. To achieve leaner and more effective processes, they can identify possibilities for digitalisation, prioritise them based on their value, and design and implement solutions that make use of digital technologies.

Lean Black Belt certified experts may assist organisations in achieving significant gains in productivity, quality, and innovation by fusing the fundamentals of Lean methodology with the newest digital technology. By utilising data-driven insights and automation, they are able to promote continuous improvement and assist firms in remaining competitive in a quickly changing digital environment.
