Continuous improvement is the backbone of successful manufacturing. Refining processes, eliminating inefficiencies, and optimising resources allow manufacturers to stay competitive, increase productivity, and gain production capacity.
This article looks at a very popular and effective methodology for driving continuous improvement on the factory floor: the 5S methodology.
What is the 5S methodology?
5S is a systematic approach to workplace organisation that improves efficiency, safety, and standardisation. Originally developed as part of the Toyota Production System, it has become a fundamental principle in Lean manufacturing and continuous improvement initiatives worldwide.
As we've covered in previous articles, the 5S consists of five key steps, each designed to create a well-organised, efficient, and high-performing workplace:
- Sort (Seiri) – Remove unnecessary items from the workspace. Only keep what is needed for daily operations, eliminating clutter that can lead to inefficiencies and hazards.
- Set in Order (Seiton) – Arrange necessary tools and materials logically to ensure they are easily accessible. Everything should have a designated place, reducing the time spent searching for items.
- Shine (Seiso) – Keep the workspace clean and well-maintained. Regular cleaning prevents defects, improves safety, and allows operators to identify issues like leaks or wear early.
- Standardise (Seiketsu) – Establish and implement best practices to maintain consistency across the workspace. Standardisation ensures everyone follows the same procedures, leading to predictable and repeatable results.
- Sustain (Shitsuke) – Develop habits and discipline to uphold 5S principles over time. Continuous training and leadership support ensure that improvements become a permanent part of the organisational culture.

The Role of 5S in Continuous Improvement
As most Continuous Improvement practitioners will tell you, the 5S methodology plays an important role in supporting wider continuous improvement initiatives by establishing a foundation for efficiency and discipline. We've put together a list of examples of how it contributes to ongoing operational excellence:
- Reduces Waste – By eliminating clutter and organising tools effectively, manufacturers can reduce time wasted searching for materials, decreasing downtime and increasing productivity.
- Enhances Safety – A clean and well-organised workspace reduces hazards such as slips, trips, and equipment malfunctions, contributing to a safer working environment.
- Improves Efficiency – Streamlined processes and well-arranged workstations lead to smoother workflows, helping manufacturers optimise resources and reduce bottlenecks.
- Supports Standardisation – Standard operating procedures (SOPs) based on 5S ensure consistency across shifts and teams, leading to more predictable performance and reduced variability.
- Encourages Employee Engagement – When employees take ownership of their workspaces and participate in continuous improvement efforts, it fosters a culture of accountability and pride in their work.
Other Key Continuous Improvement Methodologies
While 5S is a great starting point, manufacturers can further enhance efficiency and competitiveness by incorporating additional continuous improvement methodologies, we've provided a list below of CI methodologies that we often see implemented across our customers.
- Kaizen – A philosophy of ongoing, incremental improvements that involve all employees. Kaizen builds on the organisation achieved through 5S by fostering a culture of continuous enhancement.
- Lean Manufacturing – Focuses on eliminating waste (Muda) to improve efficiency and value for customers. Lean and 5S work together to create a streamlined, waste-free workplace.
- Six Sigma – A data-driven methodology for reducing process variation and defects. While 5S organises the workspace, Six Sigma applies statistical analysis to refine processes and enhance quality.
- Total Productive Maintenance (TPM) – A proactive maintenance approach that ensures machines run at peak efficiency. TPM relies on cleanliness and organisation (achieved through 5S) to prevent breakdowns and improve equipment reliability.
- Value Stream Mapping (VSM) – A Lean tool that visually maps material and information flow to identify inefficiencies. A well-structured workspace (enabled by 5S) makes implementing process improvements from VSM easier.
- Just-in-Time (JIT) Production – A strategy that minimises inventory and ensures materials arrive precisely when needed, (although there is often debate around how effective this is when applied to how most manufacturers operate in the 'real world'). 5S supports JIT by ensuring tools and materials are readily available and organised.

5S and Manufacturing Analytics: A Perfect Partnership
So where does a continuous improvement platform like FourJaw's production monitoring software add value in all of this?
While 5S provides a structured approach to continuous improvement, tools, such as FourJaw’s platform, take efficiency to the next level. Manufacturing analytics provide real-time visibility into machine performance, downtime causes, and production bottlenecks, enabling data-driven decisions that enhance the effectiveness of 5S initiatives.
For example:
- Identifying Downtime Causes – 5S ensures workstations are well-organised, while analytics pinpoint whether inefficiencies stem from production downtime caused by things such as; machine breakdowns, setup delays, or material shortages.
- Tracking Improvements – With analytics, manufacturers can measure the impact of initiatives, ensuring that changes lead to tangible performance gains.
- Optimising Resource Utilisation – Combining 5S with analytics helps manufacturers allocate resources more effectively, ensuring equipment and labour are used optimally.
Check out the case study below to see how a Continuous Improvement manager at an aerospace customer has achieved just this.
Conclusion
The 5S methodology is a valuable tool for driving continuous improvement in manufacturing. However, when combined with additional CI methodologies such as Kaizen, Lean, and Six Sigma, manufacturers can unlock even greater efficiency and productivity.
By implementing and sustaining these principles—and leveraging real-time manufacturing analytics—operations teams and CI managers can create a culture of manufacturing excellence that drives long-term success.
