Small and medium-sized enterprises are crucial to value creation in the European economy. The SMEs need continuous improvement initiatives to stay competitive. However, SMEs are less likely to implement lean practices compared to larger companies. Limited research exists on the factors that are vital for succeeding with Lean implementations in SMEs. A case study of Norwegian and Belgium SMEs has been conducted in the European research project ERIP (European Regions for Innovative Productivity). Six critical success factors are suggested, which correspond well with previous research: 1) Ensure strong management involvement. 2) Develop thorough employee participation. 3) Allocate sufficient time for preparing the organisation. 4) Focus on creating motivation to complete initiatives. 5) Build competence internally in the organisation. 6) Establish a performance evaluation system
