The 5S methodology is mainly utilized in physical manufacturing to maintain organization and efficiency and reduce waste at the microlevel. It’s a set of practices that encourage purposefulness and order within individual workspaces. However, as Lean thinking and Kanban continue to transform the digital space, many Lean tools are being adapted to meet the needs of knowledge workers.

Organization is a universal need in all industries. Whether your workspace is a physical space on a shop floor or a digital space like a Kanban board, the 5S Lean methodology can help you unlock greater levels of clarity, efficiency, and productivity by teaching you how to organize a workspace for efficiency, maintain the order of the area, and sustain the new order.
In this article we’ll explain the origins of the 5S Lean method, define each of the five components of 5S, and explain the benefits of incorporating the 5Ss into your teams.
5S and Lean Manufacturing
Like many Lean manufacturing tools that we now use, the 5S method began in Japan in the 20th century. It was part of a larger movement of incorporating visual cues and signals into manufacturing, known as visual control, visual workplace, or the visual factory (Kanban is also part of this movement). The rise of the 5S method enabled Just in Time manufacturing, which is the root of modern Lean manufacturing practices.
The 5S methodology is called such because it is made of five steps, each beginning with the letter S in its original Japanese.
Each step has been translated into English, replacing the Japanese ‘S’ words with their English equivalents:
- Seiri > Sort
- Seiton > Set in Order
- Seiso > Shine
- Seiketsu > Standardize
- Shitsuke > Sustain
5S and Visual Management
The 5S methodology increases the efficiency and effectiveness of manufacturing processes by combining the power of visual management with the basic concept of organization.
Overwhelmingly, humans are more effective in clean spaces. Countless productivity books and podcasts (such as Gretchen Rubin’s Outer Order, Inner Calm) tout the importance of starting and finishing each day with a clean, orderly workplace. With the exception of the rare “creative genius” type, who might thrive in a chaotic environment, most professionals in most industries will be more focused, more efficient, and more productive in an organized workspace.
In manufacturing in particular, an organized working environment is essential for efficiency. Efficiency on the shop floor relies upon being able to access the right tools and materials at the right time, without unnecessary movement.
The more organized the workspace, the more efficient the worker. And the more standardized the workspace organization, the more efficient the system will be.
4 Examples of Lean Manufacturing Practices
Lean manufacturing offers a holistic approach to improvement, with the methods, tools, and cultural ideals that companies need to stay innovative and agile. These examples of Lean manufacturing practices enable organizations to become nimbler and more innovative.
Value Stream Mapping
Value stream mapping can be used to improve any process where there are repeatable steps, especially when there are multiple handoffs. It’s easiest to think of a value stream like an assembly line, but there is obviously a large part of the manufacturing value stream that is not done on an assembly line. Most of the engineering, development, research, and design in manufacturing is done inside the heads of knowledge workers, making it trickier to spot inefficiencies.
Much of the waste in knowledge work occurs in the handoffs (or wait time) between team members, not within the steps themselves. Inefficient handoffs in knowledge work may not look like bottlenecks on a car assembly line, but they produce the same effects:
- Decreased productivity
- Overwhelmed workers
- Lower work quality
Analyzing and aiming to eliminate these inefficiencies at the organizational level is the first step toward becoming leaner.
Lean actions can be focused on specific logistical processes, or cover the entire supply chain.
For example, an analysis of a SKU would look like this: First, aim to visualize its path, evaluating all the participants from material suppliers to the consumer, and then conduct a gap analysis to determine necessary next steps to improve the value stream and achieve the objective. Then, make these small improvements over time throughout the supply chain, increasing organizational learning and streamlining the process of creating that SKU.
Demand-based flow (pull) manufacturing
In a pull system, inventory is only pulled through each production center when it is needed to meet a customer’s order. Pull systems in lean manufacturing allow “just-in-time” delivery of work. Unlike other work methods that allow for an unlimited amount of work at once, a pull system enables everyone at a specific organizational level to focus on one thing (or just a few things) at one time.
The benefits of using a pull system include:
- Ability to manage change
- Ability to quickly adapt work to new information
- Increased ability to scale the team to the appropriate size for the project
As they work through a list of “to-do” items in a backlog, team members pull new tasks only as old tasks are completed. This way, when something changes that impacts the business requirements (as it always does), the team can quickly adapt, knowing that the majority of work they have already completed can still be applied to the project.
Finally, because teams using a pull system are self-managed to a certain degree, pull systems contribute to the scalability of a team, or the ability for a team to accommodate different-sized projects while remaining cohesive. For manufacturers, this means teams can:
- Be more agile
- Deliver faster
- Innovate faster and more strategically
Organizations who adopt a Lean pull system are also able to significantly improve the reliability and accuracy of forecasting for their suppliers and customers.
Continuous improvement mindset
An organization-wide commitment to continuous improvement (Kaizen) is essential for sustainable success with Lean manufacturing.
At its core, Lean is continuous improvement – it’s improving product and process while eliminating redundant, excessive, or inefficient activities.
Continuous improvement can be viewed as a formal practice or an informal set of guidelines, but it must be well-integrated into the culture of an organization in order to make a meaningful and lasting difference.
Measurement, KPIs, and visualization
Lean manufacturing metrics, such as lead time, cycle time, throughput, and cumulative flow, help organizations measure the impact of their improvement efforts. Collecting, analyzing, visualizing, and socializing these metrics (through shared dashboards) is essential to promoting transparency and driving change.
Successful Lean manufacturers use up-to-date dashboards at the team, leader, and executive levels to paint an accurate picture of the impact that changed processes are having. It should be noted that the emphasis is on surfacing key performance indicators of processes, not people. This reinforces a collective responsibility by teams to pursue opportunities for improvement and focus on value creation for customers.
7 Lean Manufacturing Principles
There are seven fundamental principles of any Lean practice, which are used in Lean manufacturing, but also in all disciplines of knowledge work. A firm, shared understanding of these Lean manufacturing principles is essential for any organization hoping to sustainability and holistically adopt Lean manufacturing practices.
Optimieren Sie das Ganze
Every business represents a value stream, the sequence of activities required to design, produce, and deliver a product or service to customers. If our goal is to deliver as much value to our customers as quickly as possible, then we have to optimize our value streams to be able to do just that. In Lean manufacturing, this means creating seamless, productive systems on the shop floor, but also optimizing efforts across knowledge workers – engineers, developers, and others.
Vermeiden Sie Verschwendung
Lean manufacturing defines waste as anything that doesn’t add value to the customer. This can be a process, activity, product, or service – anything that requires an investment of time, money, and talent that does not create value for the customer is waste.
Industry trends show that companies adopting Lean manufacturing principles develop products by up to six months faster and stay 35% closer to products’ target costs than their competitors.
Eliminating waste across the value stream, instead of at isolated points, helps manufacturers create processes that require less human effort, less space, less capital, and less time to deliver products and services that cost less and have fewer defects.
Integrieren Sie Qualität
As businesses grow, the limitations of homegrown systems expose themselves. Lean manufacturers set themselves up for sustainable growth by practicing the Lean principle of Building Quality In.
The concept is fairly simple: Automate and standardize any tedious, repeatable process, or any process that is prone to human error. This allows Lean manufacturers to error-proof significant portions of their value streams, so they can reduce risk and time to market and focus their energy on creating value for their customers.
Some examples of this Lean manufacturing principle include:
- Pair programming: Avoiding quality issues by combining the skills and experience of two developers instead of one
- Test-driven development: Writing criteria for a product/feature/part before creating it to ensure it meets business requirements
- Incremental development and constant feedback
- Minimize wait states: Reducing context switching, knowledge gaps, and lack of focus
Liefern Sie schnell
When a piece of work reaches the customer, it’s valuable. Until then, it isn’t.
The Lean principle of Deliver Fast by Managing Flow is based on the idea that the faster we can deliver bits of value to our customers, the sooner we can begin to learn from customer feedback. The more we learn from our customers, the better able we are to give them exactly what they want.
To deliver fast, we have to manage flow, by limiting work in process and maintaining a relentless focus on value delivery. In Lean manufacturing, specifically, there is a heightened need to deliver quickly, because the cost of delay can run upwards of millions of dollars per day. Reducing development cycles and delivering new products or features quickly is essential for sustainability in manufacturing.
Schaffen Sie Wissen
The Lean principle of Create Knowledge is related to the concept of Optimizing the Whole.
A Lean organization is a learning organization; it grows and develops through analyzing the results of small, incremental experiments.
In order to retain that information as an organization, the learning must be shared. The Lean principle of Create Knowledge says that Lean organizations have to provide the infrastructure to properly document and retain valuable learning, so they do not repeat mistakes.
Schieben Sie Entscheidungen auf
Lean thinking is derived from the manufacturing philosophy of Toyota, which emphasized a just-in-time system of inventory management. The Lean principle of Defer Commitment says that Lean organizations should also function as just-in-time systems, waiting until the last responsible moment to make decisions. This allows Lean manufacturers to have the agility to make informed decisions, with the most relevant, up-to-date information available.
Respektieren Sie die Menschen
The success of any Lean initiative hinges upon one Lean principle: Respect People.
- Out of respect for the customer, we make decisions that will bring them the most value with minimal waste.
- Out of respect for our employees, we create environments that allow everyone to do their best work.
- Out of respect for our coworkers, we continuously strive to optimize our processes to allow everyone to deliver the most value they can provide.
Especially in manufacturing organizations, which often have teams working across the globe with different cultures, languages, and backgrounds, putting respect at the forefront of every interaction is critical for creating the type of safe, innovative workplace that will attract and retain top talent.
Lean Manufacturing in Practice
