Shitsuke is the fifth of the 5S steps - maintaining discipline through training, audits, and continuous practice.
Definition
Shitsuke, meaning "Sustain" or "Self-Discipline," is the fifth and most challenging step of the 5S methodology. It maintains 5S as an ongoing discipline rather than a one-time event through training, regular audits, management commitment, and culture development. Shitsuke requires continued attention because without it, workplaces inevitably drift back to disorder. The goal is to make 5S habits so ingrained that they're automatic—part of how work is done rather than extra effort.
Examples
Shitsuke included weekly 5S audits with scoring, monthly recognition for high-scoring areas, 5S elements in new employee training, and management gemba walks that included 5S observation. After two years, 5S became embedded in how the factory operated.
Key Points
- Shitsuke is the hardest S—sustaining is more difficult than initial implementation
- Regular audits with feedback are essential for sustaining
- Management commitment and attention signal that 5S matters
- Training ensures new employees maintain standards
- Recognition and consequences reinforce expected behavior
Common Misconceptions
Once established, 5S maintains itself. Without ongoing attention, workplaces drift to disorder. Sustaining requires continuous effort—audits, reinforcement, and management attention.
Shitsuke is just about auditing. While audits are important, shitsuke develops the discipline and habits that make 5S automatic. The goal is culture change, with audits as one supporting mechanism.
