To achieve a better understanding of the influence of National Culture, Corporate Culture and Leadership Style on Lean Six Sigma implementation and Corporate Success a quantitative empirical web-based survey with Lean Six Sigma professionals involved in the social professional network LinkedIn was carried out by Miriam Jacobs. The outcome of this survey suggests, that certain constellations of these five factors are more successful than others. Companies with an almost equal balance across different Leadership Styles and types of Corporate Culture achieve the best results, while companies equipped with a Rational and Hierarchical Corporate Culture in the absence of transformational, participative or supportive leadership are likely to fail.
