“Great things are done by a series of small things brought together.” – Vincent Van Gogh
In production, lean is more than just a method; it’s a way of doing things that companies in many fields have adopted to become more efficient and reduce waste. We’ll go deep into the world of lean in production in this blog.
How to Understand Lean in Production?
Lean in production is a way of running a business that focuses on eliminating waste, making processes more efficient, and giving customers more value. In the beginning, Toyota mostly created it in manufacturing. Since then, it has spread to many other businesses.
Companies that want to streamline their processes, get rid of waste, and improve quality and efficiency need to understand these principles.

Leader’s Tip:
Make continuous improvement a top priority. Mark Johnson, Production Manager at Precision Manufacturing Solutions, is a leader in his field. “The core of lean production is continuous improvement.” Tell your team to regularly find and get rid of waste. It’s possible to make big improvements in speed with even small changes.
Principle 1: Getting rid of waste
The idea of getting rid of trash is at the heart of Lean in production. According to this principle, many activities carried out during production do not enhance the quality of the final product or service. Lean points out seven kinds of waste:
- Overproduction: The act of producing more than what is required at present is known as overproduction.
- Inventory: Having too much stuff is wasting time and money.
- The time you spend waiting in a process.
- Transportation: We need to move things or items that do not require relocation.
- Overprocessing: When you overprocess, you use more resources than you need to.
- Defects: Defective items with poor quality that require correction or disposal are referred to as defects.
- Underutilized Talent: Not involving people in fixing issues and making things better.
Getting rid of these kinds of waste is a key part of Lean in production, and it leads to big increases in efficiency.

Principle 2: Always getting better (Kaizen)
One of the fundamental ideas is continuous growth, also referred to as “Kaizen.” It pushes businesses to keep making small changes to their services, products, or methods. The most important parts of Kaizen are:
- Step by Step: Kaizen encourages making small, doable changes instead of big, one-time changes.
- Participation of Employees: We urge all employees to actively seek ways to improve and implement them.
Sustainability: Improving things all the time takes a long time and becomes part of the mindset of an organization.
Principle 3: Pull systems
The purpose of pull systems is to ensure that work commences only upon request. Overproduction and too many goods can be expensive and wasteful, so the main goal is to stop them. Kanban, which utilizes visual cues to ensure the production of necessary items, is frequently associated with pull systems.
Pull systems have many benefits, such as higher efficiency, less waste, and a more flexible production method.
Principle 4: Continuous Flow
One of the main ideas behind Lean in production is making sure that work always comes in. In other words, each step in a process should flow right into the next one, without any stopping or holding up. One-piece flow, where goods are processed individually or in small batches to maintain continuous movement while allowing for flexibility, is often considered by people.
Continuous flow increases productivity, cuts down on wait times, and lowers waste.
Principle 5: Standardization
We establish clear and consistent guidelines for standardized procedures, ensuring that every step of the process is consistently followed. This concept has many advantages, such as:
Consistency: When methods are standardized, the results and product quality remain consistent.
Predictability: Organisations can more accurately guess what will happen when they follow standard processes.
Less Variation: Standardisation helps make processes less variable.
Principle 6: Value Stream Mapping
Value stream mapping is a powerful way to find, study, and improve the flow of information and materials needed to make a product or service available to a customer. It gives teams a visual picture of the whole production process, which helps them find waste and places where things could be better.
Value stream planning is important for finding waste in the production process and getting rid of it.
Principle 7: Treat people with respect
As part of the Lean journey, respect for people is a key principle showing employees’ importance. It pulls out:
Engaging workers means letting them help make decisions and solve problems.
We call the act of empowering workers to take ownership of their work and contribute to improving things, responsibility.
Recognition means letting everyone know how important their work is to the organization.
Respecting people makes workers happier, more motivated, and more productive.

What Practical Tools Can help for Lean in Production?
Lean in production uses a set of useful tools and methods to help businesses organize their work, get rid of waste, and make processes run more smoothly. We’ll look at the most important tools used in Lean production in this blog post. We’ll explain how each one works and how it affects efficiency and reduces waste in great detail.
Tool 1: The 5S method
In short: The 5S method represents a fundamental tool for organizing the workplace to efficiently complete tasks within a minimal timeframe. It consists of five primary concepts.
When sorting, one separates necessary items from unnecessary ones, eliminates clutter, and ensures that the work area contains only essential tools and materials.
Seiton means “to organize and arrange things in a way that maximizes efficiency and makes them easy to get to when needed.”
Shine (Seiso): Making sure the area is clean and free of dirt, junk, and dangers so it is safe and well-organized.
Standardise (Seiketsu): We will ensure compliance with the first three principles by establishing enduring methods and practices.
Shisuke’s job is to sustain the culture of continuous growth and adherence to the 5S principles.
Effects: The 5S method creates a clean, organized, and secure work area that cuts down on time spent looking for tools or materials and boosts total productivity.
Tool 2: Making things just in time (JIT)
The aim of just-in-time (JIT) manufacturing is to reduce inventory and ensure production only occurs when necessary. The most important parts of JIT are:
Inventory Reduction: In an effort to minimize moving costs and waste, Just-in-time (JIT) keeps inventory levels as low as possible.
Demand-Driven Production: Customers initiate this type of production by requesting it, thereby eliminating the creation of excess goods.
Flow Production: Just-in-time (JIT) supports the progress of work from one step to the next without stopping.
Impact: Just-in-time (JIT) manufacturing saves money, makes better use of resources, and shortens wait times, which lets businesses meet customer needs more quickly.
Tool 3: The Kanban system
The Kanban system serves as a visual management tool for tracking work and ensuring it begins promptly when required. Visual cues, like cards or boards, tell it when to start making things or get more materials.
Kanban Cards: We use these cards to showcase and track specific work items to maintain efficient production flow.
Pull System: The concept of “pull” is the foundation of the Kanban system, where work is initiated only when there is a demand for it. This keeps people from making too much.
Effects: The Kanban method improves production efficiency, reduces wasteful production, and facilitates the distribution of resources based on demand.
Tool 4: Poka-Yoke (To Avoid Making Mistakes)
Poka-Yoke is the use of error-proofing tools to keep mistakes and flaws from happening in the production process. These can be real or procedural safety measures meant to get rid of or greatly lower the chance of mistakes happening.
Finding Errors: Poka-Yoke systems find mistakes or flaws as they happen and stop them from moving forward in the production process.
Eliminating repair: Poka-Yoke cuts down on the need for repair or scrap by lowering the number of mistakes.
Poka-Yoke makes products better, cuts down on mistakes, and makes customers happier.
Tool 5: Total Productive Maintenance (TPM).
The purpose of TPM is to reduce equipment downtime and improve machine reliability. It includes actions like predictive and preventative maintenance that make sure equipment works at its best.
Scheduled Maintenance: TPM includes regular maintenance tasks that keep equipment from breaking down and cut down on unplanned downtime.
Employee Involvement: Workers are constantly maintaining and keeping an eye on equipment.
Impact: TPM cuts down on equipment downtime, lowers the cost of maintenance, and makes sure that the standard of production is always the same.
