Welcome to the nexr section of DMAIC Improve phase, which focuses on the wonderful techniques of PDCA and Kaizen Improvement Methodologies! Are you ready to advance your process improvement abilities?
You will learn how to leverage the PDCA cycle and Kaizen concepts to optimise your operations, remove waste, and increase efficiency in this second of the couse. You will learn how to maximise the effectiveness of these two approaches by combining their strengths.
PDCA is an acronym that stands for Plan-Do-Check-Act. It is a continuous improvement cycle that assists organisations in improving processes by planning a change, implementing it, monitoring the outcomes, and making modifications as needed. It is a basic but effective technology that enables organisations to improve processes over time by implementing tiny and gradual adjustments.
Kaizen, on the other hand, is a Japanese concept that translates to “improvement” or “change for the better.” It is a philosophy and set of techniques centred on continual improvement in all elements of a business. To enhance efficiency, quality, and overall performance, Kaizen emphasises tiny, incremental adjustments, teamwork, and personal discipline.
Both PDCA and Kaizen are process improvement approaches that have some commonalities but also some significant distinctions.
Both PDCA and Kaizen emphasise continual improvement and the implementation of tiny, incremental changes over time.
Both approaches include a planning, implementation, and review cycle.
PDCA and Kaizen are both built on the idea that little changes, when added together, can lead to big outcomes.
PDCA is a process improvement system that consists of four stages: Plan, Do, Check, and Act. Kaizen, on the other hand, is a concept and set of techniques that may be applied to a variety of areas inside an organisation.
PDCA is primarily concerned with finding and solving individual problems, whereas Kaizen is concerned with instilling a culture of continuous improvement throughout the firm.
PDCA is more structured and prescriptive, with a distinct set of phases to follow, whereas Kaizen is more adaptive and fluid, allowing for greater creativity and experimentation.
Both PDCA and Kaizen can be effective tools for process improvement, but which approach to choose will depend on the organization’s specific needs. When you have a single problem or process that needs to be improved, PDCA is more suited, whereas Kaizen is better suited when you want to develop a culture of continuous improvement throughout the firm.

The four stages of the PDCA (Plan-Do-Check-Act) process are as follows:
Plan: Identifying a problem or potential for improvement, setting objectives, and developing a plan to handle the problem or opportunity are all part of this stage. Identifying the present process, acquiring data, interpreting the data, and establishing the fundamental cause of the problem are all part of this process. The goal is to build a clear understanding of the problem and a strategy to address it.
Do: At this stage, the strategy is put into action, and the solution is tested. This comprises training the required employees, procuring the appropriate resources, and carrying out the strategy. The purpose is to execute the modifications and monitor the outcomes.
Check: This step entails tracking and measuring the outcomes of the previous stage’s improvements. Data is gathered, processed, and compared to the initial goals. The purpose is to establish whether the problem has been solved and the objectives have been reached.
Act: The last stage entails taking action based on the previous stage’s outcomes. If the goals are reached, the adjustments are made permanent, and the process is constantly reviewed to ensure that the problem does not reappear. If the objectives are not accomplished, the process is examined and any necessary changes are made. The purpose is to take remedial action, ensure that the problem does not return, and make the modifications needed to improve the process.
The PDCA cycle is an iterative technique that allows for ongoing improvement by being repeated several times. It is vital to remember that PDCA is a continuous improvement methodology that can be applied to any process or problem.
The DMAIC Improve stage is where the problem solutions are applied and tested. Within this stage, the PDCA approach can be utilised to help optimise the process and guarantee that the solutions are effective.
Here are some pointers on how to use the PDCA approach in the DMAIC Improve stage:
Plan: Determine the problem or opportunity for improvement highlighted in the previous DMAIC stages. Define the goals and develop a strategy to solve the challenge or opportunity. Check that the plan is in line with the general goals of the DMAIC project and that the required resources are accessible.
Do: Put the plan into action and test the solution. This comprises training the required employees, procuring the appropriate resources, and carrying out the strategy. During this step, collect data to track the progress of the solution.
Check: Monitor and measure the outcomes of the previous stage’s adjustments. Gather data, analyse it, and compare it to the original goals. To ensure that the solution is effective, employ statistical process control tools and methodologies.
Act: Take action based on the previous stage’s outcomes. If the goals are reached, the adjustments are made permanent, and the process is constantly reviewed to ensure that the problem does not reappear. If the objectives are not accomplished, the process is examined and any necessary changes are made.
It is critical to remember that the PDCA cycle is an iterative process that should be repeated several times to refine the process and obtain long-term effects.
By incorporating PDCA into the Improve stage of DMAIC, it is possible to test the solution and measure the outcomes before permanently deploying it, ensuring that the solution is effective and that the problem does not reappear.
Here’s an example of PDCA in action in the DMAIC Improve stage:
A manufacturing company has identified a problem with high reject rates on a specific product line. The DMAIC process has begun, and the Improve step is now being carried out.
Plan: The team determines that a lack of sufficient training for the operators who handle the specific product line is the fundamental cause of the problem. A strategy for providing additional training to the operators, including interactive training sessions and hands-on activities, is devised.
Do: The operators receive further training, and the procedure is adjusted to include more frequent quality control team assessments. During this step, data is collected to track the progress of the solution.
Check: The data has been examined, and the reject rate has lowered by 20%. To verify that the new process is more stable and that the problem does not reoccur, statistical process control tools are utilised.
Act: Based on the findings, the new process is permanently adopted, and the training programme is incorporated into the standard operating procedures. The procedure is constantly reviewed to ensure that the problem does not return and that the outcomes are long-term.
In this case, the PDCA approach was utilised within the DMAIC Improve step to test and measure the effectiveness of the solution before permanently deploying it. This enabled the organisation to ensure that the problem was adequately fixed and that the new procedure was stable and long-lasting.
After World War II, the Japanese automobile industry pioneered Kaizen, which was eventually followed by many other industries. Kaizen is built on the premise that modest, incremental adjustments, when added together, can produce major outcomes.
Kaizen is a team-based approach to development in which everyone in the business is encouraged to submit ideas and engage in improvement activities. It emphasises the significance of personal discipline and accepting personal responsibility for one’s conduct. Kaizen also encourages the involvement of employees at all levels of the business in the improvement process, as they are the ones closest to the process and may contribute useful insights.
Kaizen is also concerned with detecting and reducing waste in all aspects of a company, such as time, money, materials, and energy. It is founded on the quality-first philosophy, which suggests that the emphasis should be on providing the greatest quality products or services available. Kaizen also emphasises the significance of standardised processes in order to assure consistency and quality, which involves the development of standard operating procedures, checklists, and guidelines.
Kaizen is a fluid and adaptive technique that encourages greater innovation and experimentation. This enables firms to apply Kaizen to any process or problem, no matter how large or little. The Kaizen methodology also includes the concept of “respect for people,” which indicates that everyone in the organisation should be treated with dignity and respect.

To summarise, Kaizen is a powerful ideology and set of methods that assist firms in continuously improving operations, increasing efficiency, lowering costs, and increasing customer happiness. It is a team-based strategy that encourages everyone to engage and share ideas, and it is founded on the ideals of continuous improvement, cooperation, personal discipline, and respect for people.
Kaizen uses many different techniques for making improvements, some we have previously covered, some we will cover in the next modules of the course and some are covered at the Lean Six Sigma Green Belt level.
5S: This technique is used to organise and maintain a clean and safe work environment. It consists of five steps: sort, arrange, shine, standardise, and sustain. The purpose of 5S is to create an easy-to-work-in atmosphere where everything has a home and is quick to find.
JIT (Just-in-Time): This strategy reduces inventory levels while increasing efficiency. JIT is a system in which materials and products are delivered to the manufacturing line as needed, minimising the need for huge amounts of inventory to be stored.
TPM (Total Productive Maintenance): This technique is used to improve equipment performance and reliability. TPM entails incorporating operators and maintenance employees in the maintenance process in order to increase efficiency.
Root Cause Analysis: This technique is used to identify the underlying causes of a problem. Root Cause Analysis is used to identify the root causes of problems and find solutions that address the underlying issues, rather than just treating the symptoms.
Kaizen Events: This technique is used to focus on specific areas of improvement. Kaizen events are short-term improvement projects that are often conducted by a cross-functional team and focus on a specific area, process, or problem.
Standardized Work: This technique is used to ensure consistency and quality. Standardized work entails documenting the best practices and processes and then teaching staff to regularly follow them.
Gemba Walk: This method involves walking around the workplace and observing the job procedures. The purpose is to discover areas for development and to view work processes through the eyes of the employees.
Here are some ideas for incorporating Kaizen into the DMAIC Improve stage:
Implement and test the solutions. During this step, collect data to track the progress of the solution.
Monitor and evaluate the outcomes of the previous stage’s adjustments. Gather data, analyse it, and compare it to the original goals.
If the goals are reached, the adjustments are made permanent, and the process is constantly reviewed to ensure that the problem does not reappear. If the objectives are not accomplished, the process is examined and any necessary changes are made. To ensure that the new process is stable and sustainable, use Kaizen approaches such as Kaizen events and Standardized Work.
Encourage employees to give ideas and participate in improvement activities to involve them in the process.
Walk around the workplace using the Gemba walk approach to monitor work processes and uncover more chances for improvement.
Continuously monitor and measure process performance to guarantee that the problem does not return and that the results are long-term.
By incorporating Kaizen into the Improve stage of DMAIC, it is possible to employ a set of improvement approaches that can identify areas of waste and inefficiency and implement effective, stable, and sustainable solutions. It also enables for employee participation in the process and the establishment of a culture of continuous improvement throughout the firm.
Both PDCA (Plan-Do-Check-Act) and Kaizen are process improvement approaches that can be used to form an effective continuous improvement system.
PDCA can be utilised as a framework for Kaizen projects since it provides a structured way to planning, implementing, and monitoring improvement activities.
The Kaizen principle of continuous improvement can be incorporated into the PDCA cycle, focusing on tiny and gradual changes over time.
During the “Plan” and “Do” stages of PDCA, kaizen techniques such as 5S, JIT, TPM, Value Stream Mapping, Process Mapping, Statistical Process Control, Root Cause Analysis, and Standardized Work can be used to identify waste and inefficiency and implement remedies.
The “Check” and “Act” stages of PDCA can be used to monitor and measure the effectiveness of implemented solutions and make required adjustments.
Employee participation in Kaizen activities can be incorporated into the PDCA cycle, allowing them to participate in the process’s development, implementation, and monitoring.
Organizations can establish a powerful method for continuous improvement that is structured, focused on modest and gradual changes, and involves people in the process by integrating PDCA with Kaizen. This enables firms to improve procedures over time by making little changes.
There are various advantages and disadvantages to combining PDCA and Kaizen:
Increased effectiveness: Using PDCA as a framework and Kaizen approaches, businesses can identify waste and inefficiency and implement effective, stable, and sustainable solutions.
Increased efficiency: Organizations can reduce inventory levels and increase production process efficiency by implementing Kaizen techniques such as JIT and TPM.
Continuous improvement: Organizations can continually improve processes over time by employing Kaizen’s continuous improvement philosophy and PDCA’s iterative process.
Employee involvement: By incorporating employees in the process, firms can tap into the knowledge and experience of those closest to the process, resulting in a culture of continuous improvement.
Implementation: It can be difficult for firms to execute a combined approach of PDCA and Kaizen since it demands a shift in the organization’s culture and thinking.
Resources: A combined PDCA and Kaizen method necessitates resources like as time, personnel, and money.
Sustainability: Sustaining the improvements over time can be difficult, as it necessitates regular monitoring and follow-up to ensure that the problem does not recur.
Resistance to change: Employees who are resistant to change may be unwilling to participate in the process of improvement.
Overall, a PDCA/Kaizen method can be a powerful system for continuous improvement, but it requires focused implementation and resources, as well as overcoming any resistance to change and guaranteeing long-term sustainability.
Here’s an example of PDCA and Kaizen working together in the DMAIC Improve stage:
During peak hours, a retail operator has found an issue with long lines at the checkout counter. The DMAIC process has begun, and the Improve step is now being carried out.
Plan: The team determines that a lack of sufficient workers at the checkout counter during peak hours is the primary cause of the problem. A strategy is devised to enhance the number of employees during peak hours by combining full-time and part-time workers.
Do: Additional personnel are hired and trained, and the procedure is altered to include a standardised work schedule for all checkout personnel. During this step, data is collected to track the progress of the solution.
Check: The data has been analysed, and the wait times have been reduced by 50%. To verify that the new process is more stable and that the problem does not reoccur, statistical process control tools are utilised.
Act: Based on the findings, the new process is permanently adopted, and the team employs Kaizen events and standardised work to ensure that the process is constantly improved. The 5S approach is also used by the staff to arrange and maintain a clean and safe work environment at the checkout counter.
The team also employs the Gemba walk technique to go about the workplace, monitor work processes, and discover more areas for improvement.
The PDCA methodology was utilised as a framework for the improvement project in this example, providing a disciplined way to designing, implementing, and monitoring the solution. Kaizen strategies such as 5S, standardised work, and Kaizen events were used to detect waste and inefficiency and implement solutions that are effective, stable, and sustainable. The combination of PDCA and Kaizen enabled the organisation to solve the problem.
Finally, PDCA and Kaizen are both powerful process improvement strategies that may be used to form a comprehensive system for continuous improvement. PDCA is a structured and prescriptive process improvement system that focuses on solving individual problems, whereas Kaizen is a concept and set of practises that focuses on developing an organisational culture of continuous improvement.
Both techniques emphasise continuous improvement and the gradual deployment of minor incremental changes. Both techniques can be used by organisations to enhance their processes over time by making tiny changes that result in huge results. The strategy chosen will be determined by the organization’s specific demands.
Now you have an understanding of using PDCA and Kaizen in the improve phase, lets explore some of the tools and techniques you can use within them such as 5S and Visual Management
