An efficient, safe and well-organised workplace is the foundation of operational excellence. The 6S Method, a proven management system inspired by the Japanese concept of Kaizen, focuses on continuous improvement and the systematic elimination of waste. Whether applied to a factory, office, laboratory, or workshop, 6S transforms any workplace into a more productive, safer, and better-organised environment.
The 6S methodology builds on the original 5S system, developed from the Toyota Production System (Lean Enterprise Institute), and adds Safety as a sixth, essential pillar. Moreover, it is closely aligned with continuous improvement frameworks such as ISO 45001 Occupational Health & Safety and lean manufacturing principles documented by the US EPA Lean & Environment program. Therefore, explore the six steps below and discover how each one builds on the last.
1. Sort: Eliminate the unnecessary, create clarity
The foundation of an optimised workplace is order. Start by separating what is essential from what is not.
- Why? Clutter is distracting, time-consuming, and a safety hazard. A clear workspace enables focus on essential tasks.
- How? Categorise items as necessary, superfluous, or reusable. Remove anything that does not contribute to daily operations.
- Pro tip: Use colored tags or a “red tag” system to flag items for removal, relocation, or further evaluation.
2. Set in Order: Everything has its place
Once unnecessary items are removed, assign a fixed, logical place to everything that remains.
- Why? A structured workplace reduces search time, eliminates unnecessary movement, and improves efficiency.
- How? Place frequently used tools within easy reach; store less-used items further away. Use tool walls, floor markings, and labels to make organisations visible and intuitive.
- Example: Kitchen professionals keep knives, spices, and frequently used pans within arm’s reach — no wasted movement, just precise execution.
3. Shine: Cleanliness as the basis for quality
A clean workplace is a productive and safe workplace. Regular cleaning and maintenance are non-negotiable.
- Why? Cleanliness extends equipment service life, identifies early signs of malfunction, and creates a more pleasant working environment.
- How? Establish a daily cleaning routine for work surfaces, machines, and tools. Carry out preventive maintenance checks regularly.
- Benefit: A clean environment directly reduces the risk of accidents and illness. This creates a measurable benefit for both health and morale.
4. Standardize: Uniformity is key
Standardisation ensures that the improvements from Steps 1–3 are maintained consistently, not treated as one-off actions.
- Why? Standardised processes lead to consistent quality and reduce the chance of errors or regression.
- How? Develop clear rules and checklists for each step. Use visual management aids — posters, colour coding, reminders — to keep standards front of mind.
- Pro tip: Involve employees in designing standards to ensure they are practical, accepted, and owned at the shop-floor level.
5. Sustain: Live continuous improvement
The best systems are worthless without sustained commitment. Step 5 is where 6S becomes culture rather than a project.
- Why? Without ongoing reinforcement, workplaces quickly revert to old habits and patterns.
- How? Train employees regularly, recognise teams that maintain standards exemplarily, conduct periodic audits, and celebrate progress.
- Mindset: Think of 6S not as a destination. Instead, view it as an ongoing journey. Every improvement step takes you further toward operational excellence.
6. Safety: Protecting your people and resources
Safety is the most important component of 6S, and it permeates every other step. It is not an afterthought — it is the foundation.
- Why? Workplace accidents cost organisations time, money, and trust — and cause real harm to people’s lives and well-being.
- How? Conduct regular safety audits to identify and eliminate hazards. Ensure protective equipment is always accessible. Promote a safety culture where every employee takes personal responsibility.
- Tip: Visual warnings, emergency plans, and safety signage keep precautions present without relying on memory alone.
The Advantages of the 6S Method
The 6S method is more than a tool — it is a mindset that can transform how any organisation operates. With 6S, organisations consistently achieve:
- Minimised waste and maximised operational efficiency
- Improved safety, quality, and employee satisfaction
- A sustained culture of continuous improvement (Kaizen)
- Alignment with standards such as ISO 45001 and ISO 14001 Environmental Management
Start today: pick one area of your workplace and run through all six steps. With each iteration, you will see how your working environment becomes more efficient, safer, and more sustainable.
