The fifth step of 5S—Sustain, or Shitsuke in Japanese—is the most difficult to achieve. While Sort, Set in Order, Shine, and Standardize can be implemented relatively quickly, Sustain requires discipline, culture change, and leadership commitment. Many organizations struggle here, finding that initial improvements fade over time. Understanding why 5S fails at the sustain stage is critical for making workplace organization a permanent part of daily operations rather than a short-lived initiative.

The Importance of Sustain

Sustain is about creating habits and culture. It ensures that the discipline of keeping work areas organized, clean, and standardized continues indefinitely. Without sustain, workplaces quickly slide back into disorder, erasing the gains of earlier steps. Sustain is the difference between a short-term cleanup and a lasting Lean transformation.

Common Reasons 5S Fails

Several common issues explain why organizations fail to sustain 5S:
- Lack of leadership follow-through: Managers stop reinforcing standards once initial results are achieved.
- Weak accountability: Without ownership, employees assume someone else will maintain order.
- Failure to integrate into daily work: 5S is seen as an add-on rather than part of normal duties.
- Lack of training: Employees are not taught why 5S matters or how to apply it effectively.
- Focus on appearance over purpose: 5S becomes a cosmetic exercise rather than a system for reducing waste.
Recognizing these pitfalls helps organizations anticipate and address them.

The Role of Leadership

Leaders play a decisive role in sustaining 5S. They must model desired behaviors, reinforce standards through regular audits, and make 5S part of performance expectations. Recognition and feedback encourage employees to maintain discipline. When leaders visibly support 5S, employees are more likely to treat it seriously.

Building Employee Ownership

5S cannot be sustained through management pressure alone. Employees must feel ownership of their areas. Assigning responsibility for specific zones, encouraging improvement suggestions, and involving staff in setting standards all build engagement. When employees see that 5S makes their work easier and safer, they are more motivated to maintain it.

Integration into Daily Management

Sustain works best when 5S is embedded into daily routines rather than treated as a special project. Tiered daily meetings can include quick 5S checks. Visual management boards can track compliance. Leader standard work should include reviewing 5S conditions regularly. These practices ensure that 5S does not fade from attention.

Real-World Examples

A factory that launched a 5S program saw dramatic initial improvements, but within six months, clutter returned. An investigation revealed that leaders stopped auditing and employees viewed 5S as optional. By reestablishing clear responsibilities, providing refresher training, and rewarding high-performing teams, the company stabilized its 5S efforts.

In an office, digital 5S efforts to clean shared drives faltered because no one was accountable for maintaining standards. By assigning ownership of specific folders and conducting quarterly audits, the office regained control of its digital assets.

Sustaining Through Culture

Ultimately, sustain requires culture change. Organizations that succeed embed 5S into their values and practices. Employees internalize discipline, taking pride in orderly workspaces. New hires are trained in 5S from the beginning. Sustain becomes easier when employees understand that 5S is not just about cleanliness—it is about efficiency, safety, and respect for people.

Conclusion

Sustain is the hardest step of 5S because it requires long-term commitment and cultural transformation. By addressing common reasons for failure, engaging leadership, and embedding 5S into daily management, organizations can prevent backsliding. When sustain is achieved, 5S becomes a natural part of the work culture, ensuring that the benefits of workplace organization are preserved and amplified over time.
