This article describes a new idea in applying the 5S concept (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) to create a quality work environment for small and medium-sized enterprises of ship components. The success rate of implementing the 5S concept must be known based on assessing the effectiveness of the 5S concept application. Assessment of the effectiveness of the application of the 5S concept requires measurement indicators that are with the characteristics work environment of small and medium-sized enterprises of ship components. Determination of standard indicators for the implementation of 5S enabling to assessing the effectiveness of the implementation of 5S repeatedly and consistently. Indicators for the assessment of 5S effectiveness are obtained using the Delphi method. The results showed that the Delphi method obtained 37 indicators that can be used to assess the effectiveness of the implementation of 5S on small and medium-sized enterprises of ship components with an agreement of 75% to 100%. This assessment standard can be used in every phase of the 5S implementation, namely the initial implementation stage up to the system maturity stage. This assessment standard can also be used in similar small and medium-sized enterprises implementing 5S.
