What tool is often utilized to assist in the Sustain phase of 5S?

The Sustain phase of 5S is focused on maintaining the gains achieved in the previous phases and ensuring that the improvements are upheld over time. One of the most effective tools used to assist in this phase is visual controls.

Visual controls help in making the standards of the newly implemented processes visible and easily accessible to all employees. They serve as constant reminders of what the expected standards are, thus encouraging everyone to adhere to them. For example, color-coded labels, shadow boards, and clear signage can help in organizing the workspace and making it clear where items belong, which aids in maintaining order and cleanliness.

While performance review meetings, safety audits, and regular training sessions may play a role in the overall improvement process, they are not specific tools tailored for the Sustain phase in the context of 5S. Visual controls are directly aligned with the goal of sustaining the improvements by providing ongoing visibility and reminders of established standards, thus reinforcing the habits formed during the initial phases of 5S.
