Which principle is essential for the effectiveness of the Sustain step?

The principle of routine maintenance of cleanliness is essential for the effectiveness of the Sustain step because it emphasizes the importance of maintaining improvements over time. This principle ensures that the systems and practices established during the earlier phases of a project, particularly in Lean methodologies, are not only implemented but also consistently upheld. By incorporating regular upkeep and a commitment to cleanliness, organizations can foster a culture of continuous improvement and avoid backsliding into old habits.

Additionally, this approach promotes accountability among all employees, encouraging them to participate actively in maintaining a clean and organized work environment. Regular checks and balances help reinforce the new standards, making it easier to identify and address issues as they arise. As a result, sustainability in improvements is achieved, ensuring that the benefits of the initiative are long-lasting.
