What is Lean Transformation?
The strategic, tactical, and operational enhancements that firms make in order to provide more value to their customers are referred to as lean transformation. These advancements mark a significant shift in company mindsets, moving away from conventional practices toward a more value-driven, simplified approach.
The Lean transformation does not follow a single strategy: In some companies, Lean starts out as a grassroots initiative, driven by a single team or department, and eventually expands across the entire company. Alternatively, some organizations make a deliberate, coordinated push to embrace Lean techniques, principles, and business structures at their highest levels.
The ultimate objective of virtually every Lean project is to enable businesses to consistently provide greater value to their customers.
Why is Lean Transformation Important?
In today’s rapidly changing and dynamic environment, the ability to deliver value swiftly and predictably is more crucial than ever. And the core of lean is the efficient, predictable delivery of value.
By removing organisational structures, procedures, and ways of thinking that impede the effective delivery of value, lean transformation helps businesses to make the fundamental transition from surviving to flourishing.
The Lean Transformation Model
There are five essential elements that all successful transformations share, despite the fact that not every organisation tackles Lean transformation in the same way. As follows:
A value-driven mission and ongoing process optimization
Lean management system, sustainable capability development, and lean thinking, mentality, and assumptions
1. Value-Based Goals
In order to consistently, reliably develop and deliver more value with less waste, organisations turn to lean manufacturing. The core motivation behind all Lean transformations is this.
In Lean, value refers to any action, process, output, or outcome that directly benefits and satisfies the customer.
Waste is anything that does not benefit the client in some way. This singular idea should serve as the cornerstone for the entire Lean transformation, guiding all decision-making processes.
2. Improvement of the Process Constantly
The idea of continuous improvement, or more particularly, continuous process improvement, is another basic Lean principle. Continuous process improvement needs businesses to embrace experimentation, which occasionally entails accepting failure as a necessary part of the learning process. In practise, this is much harder to do than it might first appear.
Lean businesses commonly employ the PDCA cycle (Plan-Do-Check-Act) to organise their attempts at continuous improvement. In the PDCA cycle, which resembles the scientific process, one develops a hypothesis, creates a plan to test it, analyzes the findings, and subsequently puts any lessons learned into practice.
3. Development of Sustainable Capabilities
Compared to strength training, capability development is akin to building and sustaining the muscles necessary for a company’s functioning.
Employing a diverse staff, promoting from within, encouraging and supporting Lean education, providing chances for internal professional growth, and fostering constructive conflict are all ways that lean organisations support the creation of sustainable capabilities.
Low turnover is a crucial sign of successful capability development.
4. Lean Management Methodology
Serving others is at the heart of lean leadership. The responsibility of leaders is to bring teams together around a common goal and then remove any barriers standing in their way of achieving it throughout a company’s Lean transformation and beyond.
Leaders are encouraged to spend more time “in the trenches” with their teams to better understand the problems they face and assist in resolving them.
Data-driven decision-making is another crucial component of Lean leadership: Factual information should consistently guide value creation and delivery, surpassing opinions. It is the responsibility of Lean leaders to promote a data-driven, scientific approach to work.
5. Assumptions, Lean Thinking, and Mind set
Finally, a successful Lean transformation necessitates a change in perspective, attitude, and presumptions since these factors collectively define company culture.
Any organization’s culture may be changed, but it takes time and effort.
To complete a Lean transformation, significant cultural changes must take place, including:
Internalizing the Lean philosophy
Embracing trial and failure; celebrating learning over “wins”; putting the production of value ahead of the generation of profit
- committing to a data-driven decision-making process; encouraging horizontal communication; amplifying views throughout the organisation; changing the leadership role; rejecting the notion that those with the highest salaries have the best ideas
- Promoting accountability and transparency while rejecting “politics”

Phases of Lean Transformation
Now that you are aware of the elements of a typical Lean transformation, let’s explore how to view its stages, or the processes that an organisation must follow to implement lasting change.
In this first step, firms assess their needs, inventory their current organisational structures, and decide how they will transition to a lean organisation
The following step is initiation, at which time it is important to acquire executive support, identify Lean champions, and start training programmes to ensure that everyone is aware of what Lean is, what the transformation’s objectives are, and what will be involved in it.
The next step in a successful metamorphosis is training. Some businesses will decide to hire outside Lean consultants to help them through this pivotal phase of their transition. Key Lean ideas and practises are taught to the entire organisation as part of training.
It’s crucial to focus on how to operationalize core Lean ideas, such as continuous improvement and respect for others, in addition to learning about these ideas in general.
Team members must understand how to apply these Lean principles in their daily activities and how organizational structures may need to change to align more closely with the company’s Lean goals.
Most organizations, accustomed to lower levels of visibility, must increase their visibility when implementing lean at scale. It is through this enhanced visibility that organizations achieve higher standards of responsibility and performance. But many Lean transformations fail in the absence of the instruments that make this visibility possible.The proper equipment can make a huge difference.
• Mapping Value Streams
You are aware that any Lean transformation aims to centre the business on value generation. This often involves changing not only how teams approach their work but also the fundamental framework within which they operate.
Companies engage in value stream mapping, an enterprise-wide process, to:
- Identify how value currently flows (or doesn’t flow) through their business.
- Choose an “ideal state” to achieve, such as organizing cross-functional teams around specific value streams.
• Continual Development
The next phase is to continuously analyse and improve the new value streams and the supporting structures.
As Lean transformation matures and cultural shifts persist, the organization advances to the final stage of continuous improvement.
Mature Lean businesses consistently pursue methods to adapt, improve, and evolve existing practices, processes, and structures to enhance value creation.
Three Criteria for a successful lean transformation
1) The Lean Transformation needs to be driven by strategy
All businesses must address not “which processes can be improved” (as all can be improved), but “which techniques need improvement”. Where are the performance gaps necessary for gaining a competitive edge, then, is the question for Lean Transformation.
These need to be recognized, examined, and the subject of improvement.
Assigning “Lean” tasks to staff may lose focus, causing changes motivated by a desire for improvement rather than strategic alignment. Therefore, the primary focus in process setup should center on how managers engage in the long-term Lean Transformation.
2) Call managers to account
Not just Kaizen Events, Six Sigma training, or the application of lean techniques may result in a genuine transformation. Managers are in charge of making ensuring that all initiatives forward the lean approach. So, the only person who can persuade other workers of the shared objectives is a leader who lives the Lean ideology.
3) Involve managers in their duties
The individuals directly involved in production must make improvements. After all, those who perform the tasks are the most knowledgeable. If we help employees comprehend the larger system (value stream) and how their actions affect it, we can produce better long-term results.
They can only find prospects for improvement in this way. This entails giving individuals space and delaying the imposition of hasty actions that are ineffective in any way. Many of us are eager to skip steps to expedite change and quickly resolve issues, checking them off our list.
However, such modifications don’t last over time. Giving all affected employees the impression that their thoughts support the changes through well-planned change management and active participation in the whole process is crucial.
Why does Lean Transformation fail?
You might be shocked to learn that 70% of transformations are unsuccessful. Why is this true when a lean transition is taking place? Most frequently, it’s because the transition doesn’t go far enough in most cases. Organizations declare their transformation successful after making superficial adjustments and possibly adopting some Lean terminology.
Lean transformation is fundamentally a cultural phenomenon that cannot be artificially created. Only when concepts such as continuous improvement, respect for people, and a persistent focus on value become deeply embedded in the organization’s culture will the true potential of Lean transformation be fully realized.

The 4 Lean Principles
First rule: Respect for people
This is a rule that I have seen openly violated in most of the sites where I have observed what some claim to be a Lean implementation.
Do you feel respected at work? is a question I posed to ten people at random. No, was the response. One of the core principles of Lean, adapted from TPS (Toyota Production System), empowers individuals.
Japan, a nation that lays an extraordinary focus on respect for individuals, is where TPS was first developed.
I use the term “peculiar” because it’s a word often employed in a superficial way in numerous countries and businesses. All things considered, one of the essential tenets of effective Lean adoption must be respect for people.
Second Rule: Pull or Push
Okay, let’s go on. Many Lean practitioners rank this as their number one preference. Do we switch from Push to Pull processes? This idea is supported by JIT or Just in Time production, a core tenet of lean manufacturing that calls for “the right product of the right quality in the right quantity at the right time.” JIT implementations in companies often result in a move from Push to Pull.
For those who are unaware, Pull is production based on demand, whereas Push is output based on forecasts.
Transitioning from Push to Pull is acceptable, but practitioners must consider ecological balance and the economics of the business. Pull requires flawless synchronisation between production planning and consumer demand to shipping. Many businesses will tell you that accomplishing this is a gargantuan effort if you ask them.
Therefore, it’s advisable not to completely transition it to a Pull system. Achieving optimization in the operations of a sub-process requires ensuring that it operates harmoniously in a Pull fashion. However, transitioning an entire organization from a Push perspective to a Pull approach could pose challenges.
Principle 3: Who Defines Value?
By definition, lean is a philosophy that focuses on eliminating waste and minimising non-value-adding operations. Non-value-adding activities are those that don’t provide value for the client.
Please take note: To the client! I’m aware of several businesses that define value from their perspective, driven by valid reasons to avoid bankruptcy.
Keep in mind that the client, not the company, determines the worth of the product. The firm may wind up with non-value-adding activities that are necessary for the business even if it does its best effort to match the list of value-add activities. The issue is that most companies charge their clients for services that don’t offer value. At the very least, that is incorrect.
Principle 4: Employee Training
Now, it goes without saying that training staff is necessary for a new initiative to thrive. But in Lean, things are a little bit different. Simple instruction is insufficient. Enough Gemba walks and Kamiyashibai Board implementation must come after it. Importantly, even after training, organizations should actively appreciate individuals for taking responsibility for their mistakes. This makes a significant contribution to maintaining the respect element.
In conclusion, I may have been tempted to include a discussion about management, but I must pause here for the time being. Lean implementation would require one full day for management’s input, and in this case, space appears to be a concern.
Top 10 Benefits of Lean Transformation
This type of holistic Lean transformation has a significant influence on many areas, from productivity and morale to the bottom line. These are the top 10 advantages of lean, according to a poll of more than 3,000 knowledge workers conducted by the Lean Business Report.
• First, control team/process complexity.
Lean enables businesses to comprehend their value streams, which enables them to start eliminating and optimising what does not bring value to the consumer. Organizations sometimes fail to realize the extent of time, effort, and creativity lost due to process complexity before defining their value streams.
Duplicate work, a lack of alignment, and communication issues are all signs of substantial organisational inefficiencies. Optimizing the flow of value to the customer is practically impossible without knowledge of how value moves throughout the organisation.
• #2 Business Procedures That Are More Effective.
Efficiency in processes is crucial for corporate agility, enabling rapid course adjustments in response to customer demands. Efficiency allows businesses to rapidly introduce new features, products, or information to the market, initiating quicker customer feedback collection.
Before an idea reaches the customer, it often must navigate through a maze of inefficiencies stemming from suboptimal processes. Lean enables teams within organisations to visualise, manage, and optimise processes in order to maximise value, speed up work, and remove any barriers to the customer’s value flow.
• Third, better control over shifting priorities.
The ability to coordinate efforts amid changing priorities is linked to corporate agility. Lean organisations are flexible and light enough to change course in response to changing demands. This generates a significant competitive advantage, especially for businesses operating in sectors with a high rate of change, like technology.
• #4 Improved Team Visibility of the Project.
“Optimize the whole” is a foundational tenet of Lean. Starting at the organisational level, organisations must first determine how value moves across the many teams and departments that make up their organisation. Value stream mapping is the term for this exercise.
When lean teams start defining and identifying their collaborative work processes in relation to the corporate value stream, they engage in a value stream mapping activity. Teams frequently find it helpful to visualise their processes and actively monitor their workflow in order to hold themselves responsible to a procedure.
Kanbanis used by about 83 percent of Lean teams to visualise, manage, and improve their operations.
Teams benefit from improved project visibility when implementing Lean with Kanban. They can see where work is in the process, who is working on it, when it is due, and other information about how work moves through their process.
• Increased Team Productivity is number 5.
It’s not surprising that most teams find it difficult to achieve productivity targets in settings where team members are encouraged to take on more responsibilities than they can handle. Every assignment, project, email, drive-by conversation, meeting, etc. causes people to lose focus and work less efficiently. The problem here isn’t working more quickly; it’s working more deliberately.
Lean compels teams to actively reduce the volume of work they are handling, a process referred to as WIP (Work in Progress) reduction. Limiting WIP can improve team collaboration by motivating them to concentrate on completing each value-adding task as a unit. Teams using Kanban are able to sustainably increase output while reducing stress thanks to their improved teamwork and laser-like concentration.
• Shortened Lead Time
Teams can concentrate on finishing tasks as quickly as feasible when they restrict their WIP and improve their process for value delivery. This approach enables them to shorten the time interval between a work request and its delivery to the client.
Lean organisations can obtain feedback more rapidly thanks to shorter lead times, which they can use to further improve their activities.
• Boosted group spirit.
Respect for people” is a fundamental Lean principle, and employees in lean organizations are motivated to deliver high-quality work. They also understand that employees want a location where they can learn, develop, and evolve—not just function as a cog in the machine.
This esteem motivates Lean leaders to cultivate the autonomy, mastery, and purpose that teams require to produce excellent work.
In this regard, Lean teams list boosted team morale as one of the top 10 benefits of the methodology, along with improved cooperation, less complexity, and shorter lead times.
• Improved Stakeholder Visibility
You now understand how Lean teams utilize Kanban to enhance project visibility at the team level. The appeal of Kanban is that teams organise their work on Kanban boards, which result in a more transparent workflow for stakeholders. Stakeholders at every level of the firm can quickly and easily grasp the status of various initiatives by taking a quick look at a team or department’s Kanban board rather than holding status meetings with their direct reports to discuss status meetings of their direct reports.
This allows leadership to spend more time at the gemba, where the work is actually done, to better understand the company and the individuals who have direct access to the product.
• Lower Costs
After implementing Lean, firms frequently are able to lower their operational expenses thanks to these improvements in efficiency, productivity, lead time, agility, and visibility.
It’s no secret that every company wants to grow profits and cut costs, and many businesses approach the implementation of Lean with this as their first priority. However, this could be harmful: A superficial Lean implementation that lacks the deeper knowledge of why (to maximise customer value) is possible and won’t have the transformative impact of a more principle-driven deployment.
• Consistent Customer Value Delivery.
Finally, Lean teams said that Lean enables them to deliver customer value in a manner that is more predictable. “Lean development is the art and practise of basing commitments on reality rather than forecasts,” says Lean influencer Mary Poppendieck.
Despite starting earlier, encouraging change, delaying decision-making, and completing tasks faster than traditional methods, lean development results in more predictable results.
Collaboration, communication, and innovation are fostered by lean organisations. It enables them to offer goods and services that reliably and consistently add value for customers. Lean firms get rid of anything that does not benefit the consumer, which increases their adaptability, agility, and innovation.

Disadvantages of Lean Transformation
Using a management approach that emphasises continual improvement has several benefits. There are, however, several things that leaders need to be mindful of while implementing any new procedure.
1. The Inventory Issue
- Low stock levels are typically maintained in lean management implementation to reduce carrying costs.
- As a result, businesses must rely on their suppliers and trust that they can adapt to supply items promptly and effectively.
- Any disturbance to the company’s inventory operations might be fatal.
2. Difficult to Transition
- Lean management approaches may not always be well-received by employees. It will take a lot of patience and a thorough reorganisation of work processes to execute this style. Longer-tenured employees might not feel comfortable with this.
- Leaders must therefore be open and honest about all upcoming changes in the organisation.
- It’s also necessary to give time for queries from staff members who aren’t yet on board with the changeover.
3. High Implementation Cost
- It is often the case that all existing systems and production processes must remain in place when introducing lean management to a company that has never used it before.
- Companies unprepared for the added expenses of introducing new equipment and training programs may end up incurring significant costs due to this situation.
4. The Drawback of Over-Structuring
- It might not be necessary to overhaul everything. Determining what should be included in lean management and what shouldn’t is a difficulty for leaders.
- Understanding the effects of incremental adjustments is crucial in this situation because leaders might push systems beyond what they may be able to provide.
Problems solved through Lean
A lean transformation typically begins as a top-down initiative, initiated by senior management or even by the upper management of a corporation. With that said, senior leaders address the issues that are the focus of attention:
- Increasing profit • Increasing customer satisfaction • Reducing delivery times • Eliminating project delays • Improving quality • Managing complexity
Identify, document, and communicate the actual pain points to all relevant parties during the deployment process, regardless of what they may be. Maintain a dynamic document or wiki page that has all the information to ensure that all staff members and leaders are aware of the transformation’s true objectives.
Another caution to be aware of is having too many objectives and issues to address at once. Better is having fewer. If your main goal is to raise the standard of your work, communicating that is considerably simpler.
Compare that to enhancing quality, cutting delivery times, boosting revenue, and satisfying customers. Simply put, it won’t work.

12 Challenges to Lean Transformation
- Lack of a central focus causes decision-making, prioritisation, and problem-solving to be confused with several “optimal decisions” in each given situation.
- Not Linked to Strategy: Lean may not succeed if it isn’t actively linked to and used to realise strategy.
- Armchair Management: This term suggests that decision-makers get information and act on it while seated at a desk, omitting travel to observe events in the “real world.”
- Unpredictable or absent routines: Lean will not succeed if a Plan-Do-Check-Act (PDCA) mindset is not ingrained throughout the organisation.
- Short-term Thinking Is Not Connected to Long-Term Thinking: When short-term thinking is not connected to long-term thinking, actions for short-term victories can quickly sabotage long-term victories.
- Having several improvement languages: Having several improvement languages results in confusion and, eventually, the absence of a single, comprehensive strategy.
- Misalignment: The organisation will become confused and have conflicting priorities if it is not in alignment with its strategic objectives, operational priorities, top issues, etc.
- When you separate daily management from improvement, you establish distinct periods for “time to work” and “time to improve.”
- A culture that lacks respect or consistently fails to value mutual respect and trust will prevent transformation from succeeding.
- Politics: A transition can easily be derailed for personal motives by one or two influential members of a group, such as a doctor, board member, or senior leader.
- Hidden Issues: Without visualisation, issues go unnoticed and erode both culture and operations, which leads to the failure of the Lean transformation.
What is lean six sigma?
Lean encourages work uniformity and flow while Six Sigma focuses on eliminating waste (non-value added processes and procedures) and improving process contro. The line between Six Sigma and lean has blurred, and people are increasingly using the phrase “lean Six Sigma” because successful process improvement requires incorporating elements from both methodologies.
Lean Six Sigma is an evidence-based, data-driven improvement methodology that places a higher priority on fault prevention than defect discovery. By lowering variance, waste, and cycle time and encouraging the adoption of work standardisation and flow, it boosts customer satisfaction and bottom-line results while giving businesses a competitive edge. Every employee should take part in it, and it applies whenever there is variance and waste.
Place for six sigma in a Lean Transformation
Six Sigma has a position in a lean transition without a doubt. The one drawback I’ve observed to a “Six Sigma project” over the years is that occasionally enthusiastic proponents waste limited resources pursuing near perfection when it’s just not essential and doesn’t make sense from a business perspective. Here’s how I view a “lean transformation” and the function of Six Sigma and lean tools.
- Consider the tools for lean and Six Sigma as two drawers in a single toolbox. Lean tools are relatively simple tools that anyone in the business can learn and use. They focus on reducing waste.
- On the other side, Six Sigma tools are a more complex set of tools that are required to address the more complex issues that using lean tools frequently exposes. The use of Six Sigma tools necessitates more in-depth training, formal technical expertise, and occasionally complicated software.
- Understanding process variation is a key component of Six Sigma, as is figuring out how to quantify, curtail, and manage variation within predetermined bounds. Determining what constitutes normal variation and what requires corrective action is also helpful.
- DMAIC (du-may-ik), which stands for Define, Measure, Analyze, Improve, and Control, is a popular and incredibly effective methodology for carrying out Six Sigma initiatives. VOC (voice of the customer), DOE (design of experiments), regression analysis, process capability studies, VSM (value stream mapping), HOQ (house of quality), FMEA (failure mode and effects analysis), ANOVA (analysis of variation), and hypothesis testing are a few examples of Six Sigma tools.
Most powerful use of Six sigma
Understanding the customer’s CTQs (Critical to Quality) requirements and then internally engineering the CTPs (Critical to Process) characteristics to ensure that the process will deliver those CTQs at a Six Sigma level of performance, i.e. no more than 3.4 defective parts per million, is, in my opinion, the most effective use of Six Sigma (DPM).
There were many “industry standards” that customers utilised to create their goods in the wire and cable industry, where I spent 35 years working. These were frequently the CTQs for things like making sure the electrical or digital signals stayed within the required bounds to satisfy certain applications for that particular cables.
12 Essential Lean Six Sigma Concept and Tools
1. Cellular production
A lean manufacturing strategy for process improvement is cellular manufacturing.It is characterized by two essential traits: manufacturing cells and grouped components.A cell of machines in cellular manufacturing produces families of parts.
Each manufacturing cell is clearly defined and isolated from the others, and each cell is ultimately responsible for the family of parts and components. Consider cells as little manufacturing sites contained within a larger manufacturing complex. Group technology is what we call this.
It serves as a substitute for the conventional production line. A production line refers to a continuous line of workers who add value to the product, starting from receiving the raw materials to the final product.
Because each component in a manufacturing line depends on the components that come before it, the main drawback is that any disturbance along the line can stop the entire operation.
Rearranging workstations is a component of cellular manufacturing, which enables production with fewer downtime and continuous flow.
In the realm of manufacturing, all processes and equipment required to make a component are situated close to one another. in particular, a “U” shape. Workers spend less time travelling back and forth between manufacturing lots and more time enhancing the component by arranging the machine in small manufacturing cells and adopting a “U” design.
You can accomplish one-piece flow by placing tools and workstations in a pattern that makes sense. One-piece flow, often referred to as single-piece flow and continuous flow, is when your products pass through the production process at a pace set by your consumers’ demands.
2. Takt period
Takt Time describes the speed at which a finished product is produced in order to satisfy client demand. It is a crucial tool for determining if goods are moving efficiently from one station to the next, ensuring that you can satisfy client demand.
The word “Takt” in German belongs to the vocabulary category of time and rhythm.In this sense, “Takt” symbolizes your company’s rhythmic pulse. Similar to a music conductor, Takt Time equips you with the means to measure processes, ensuring continuous flow and optimizing equipment and procedures.
The time available for production should align with the time employees actually dedicate to working on the final product, minus factors such as meetings, breaks, and other associated activities. Consumer demand, on the other hand, is a measurement of how many things a customer anticipates purchasing.
Over the same period of time, such as a day or a week, both of these variables ought to remain stable.
Takt Time does not represent the number of labor hours utilized to manufacture a product. It refers to the total time required to produce a product, from start to finish, ensuring the achievement of continuous flow.
3. Prescriptive work
The idea of standard work is straightforward. It alludes to the process of recording procedures, steps, supplies, equipment, turnaround times, and more. At its foundation, process improvement is about making sure your operations function as smoothly as possible and that your staff are embracing your process improvement approach. To achieve your optimum Takt Time, standardised labour is crucial.
What advantages do standardised tasks offer?
The use of best practices; continuous process improvement; and waste reduction
Enhances scaling efforts, increases abnormality visibility, and reduces time spent speculating.
4. Continuous flow or one-piece flow
This concept emphasizes reducing batch sizes to eliminate system constraints, involving swiftly progressing a product or piece of information from one value-added processing stage to the next without interruptions.
5. A pull Kanban system
In a Kanban pull system, a customer process directs a providing process to produce a good or piece of information when needed.
In a pull system, the product meets rather than exceeds customer demand thanks to JIT (Just in Time) efficiency. You will find it simpler to react to market pressures when using a pull method, but the main goal is to produce what the consumer wants when they want it.
Kanban, on the other hand, describes the signals employed in a pull system via scheduling together with travel instructions in the form of straightforward visual cards and containers.
Contrary to “common knowledge,” which claims that a corporation should finish things in huge batches, this isn’t the case.
This practice, referred to as a push system, entails completing the product before the consumer is ready to receive it. The main drawback of this approach is the cost of maintaining inventories and the needless busyness of processes.
What advantages does a Kanban pull system offer?
- Increased market dynamism – Whether it is market circumstances that limit scalability or a feature of the product itself, it might be detrimental to have inventory made up of unsellable products. Investing less money in storage space for inventory will occur.
Less work-in-progress (WIP) • Improved working environment – Kanban offers visual clarity and can encourage reasonable and objective conversation among team members – Easy monitoring – All team members will receive continuous performance feedback via a breakdown of each stage from beginning to end.
6. Five Reasons
A tried-and-true technique for problem analysis and resolution is the five whys. Instead of putting a band-aid solution that would ultimately result in the problem reappearing in the future, you may frequently identify the fundamental cause of a problem by asking the five whys.
Since cutting through the symptoms and getting to the core causes is the quickest approach to solve a problem, asking yourself why is crucial.
7. Rapid switchover/SMED
The Single Minute Exchange of Dies (SMED) procedure reduces changeover time by categorizing machine components as either internal or external, and then converting the internal components for external replacement while the machine continues to run.
Transitioning more internal setup activities to external ones is better because internal changes can only take place when the system is not in use.
Shigeo Shingo created a three-stage process that, by externalising and streamlining steps, shortens the time needed to swap over a machine. In order to lower batch sizes and manufacture just-in-time, shorter changeover durations are used. This idea helps shorten setup time to increase adaptability and response to client changes.
8. Poka Yoke/Mistake Proofing
a method that, by including preventive inbuilt responsiveness in the design of the product or production process, eliminates operator mistake.
The majority of processes can benefit from mistake proofing, but some situations call for it more than others.
These situations encompass instances where a process is prone to frequent human errors, when customers might make mistakes, when a minor error could escalate into a major one, or whenever there is any possibility that an error might cause significant disruption.
Mistake proofing has the following advantages:
- Encourages accountability and process improvement
- Requires little effort and takes little time • Ensures that the right conditions exist before creation and avoids
- stops flaws from occurring; finds and gets rid of disruption’s sources
Poka Yoke is an excellent tool for catching mistakes early before they spiral out of control.
9. Leveling the workload/Heijunka
the notion that, despite the fact that customer order patterns may be extremely changeable, all of our operations should gradually produce constant amounts of work (day to day, hour to hour).
This tactic involves carefully scheduling various product mixtures and their volumes over a period of time.
10. Complete fruitful upkeep (TPM)
a group-based strategy for raising OEE, or overall equipment effectiveness, which includes performance, quality, and availability. This helps to design a plan for developing staff autonomy for equipment maintenance.
The TPM programme aims to boost staff morale and job satisfaction while also significantly increasing production.
11. Five S
5S is a five-step system designed to establish and maintain a visually ordered workspace for ongoing process improvement and efficiency.
This technique makes it very easy to evaluate the current organisational structure and get rid of everything unnecessary.
Sorting out involves examining all your work instruments and supplies to determine what is necessary and what is not. Put each item’s value into perspective by asking yourself:
- Put things in order – Once you have eliminated the extraneous clutter, you can rearrange the workplace to align with your team’s needs and short-term objectives.
Create a schedule for routinely maintaining and cleaning tools and equipment.
Standardize – Make one-time actions into routines. Set aside time to assist in fostering an environment where duties become usual, whether it be through the use of an online checklist or verbal reminders.
Sustain – Ensure sustainability over the long term. Everyone must support the new initiative, whether they are managers or recent hires.
This is why it’s crucial for process improvement to document procedures and make sure they’re simple to find.
A four-phase graphical model for implementing change at your company is the PDCA/PDSA cycle. Repeating the PDCA/PDSA cycle is necessary because the method is iterative. Especially for repetitive operations, it is a good idea to apply this model at the outset of a process improvement project.
- Plan – Identify a problem or an opportunity and lay out a strategy for ongoing transformation. You must construct a hypothesis as to what the potential problems would be. Do: This is the trial-and-error stage. Realistically, this will be a small-scale experiment that allows you to quickly measure outcomes and better understand your hypothesis. Check to see whether the issue has been resolved.
Act – Repeat the initial test on a larger scale if it proved successful.

In order to implement lean principles, one must match efficiency, effectiveness, and productivity with process, people, and purpose. The summary is provided below for your convenience.
- Efficiency is an internal performance indicator for a process that demonstrates how successfully it turns inputs into outputs. “Doing things right” is what it is.
- Effectiveness: an objective indicator of performance that shows how well a Process satisfies the needs of diverse stakeholders. Doing the right things is what it is.
- Productivity evaluates how well a business converts raw materials into finished goods. Effectiveness and efficiency combined create productivity. A business must be both effective and efficient in order to be productive.
- Process: How can we simplify, improve, accelerate, and reduce the cost of the process?
- People: How can we improve our workforce? How can we increase engagement and commitment?
- Goal: Success through goodness. How do we develop values that are enduring for all parties involved?

What is Lean Management?
Lean management is a holistic strategy for an organization’s ongoing growth. It aims to achieve a waste-free organization through lean transformation. To achieve this vision, organizations actively pursue numerous lean goals based on quality, price, time, and personnel considerations.
What are the seven forms of waste in Lean management?
- Overproduction, over processing, redundant motion, transportation, inventory, waiting time, defects (rejects and rework), and defects.
- Redundant motion: this is a result of inefficient labour, machine, or asset movement.
- Transportation: empty runs and transitions between processes are both regarded as waste.
- Inventory: Stocks of consumables, supplies, and raw materials in warehouses as well as partially finished goods before the subsequent processing step are also regarded as waste.
- Waiting for procedures, supplies, coworkers, and machines results in waiting time.
- Defects are manufactured components that do not meet customers’ quality expectations and are subsequently returned.
- Overproduction:This occurs when goods are produced without a customer order. Throughout the processes of handling, moving, and storing, people produce waste.
