The purpose of this study was to investigate how Lean can be applied in an educational environment to improve operational processes. The application of the Six Sigma methodology blended and supported by the application of various Lean tools is demonstrated in a case study of a kindergarten. Multiple tools, such as: the fishbone diagram; A3 reporting; ‘5 Why’s’; process mapping; waste analysis; and 5S amongst others led to a reorganisation of the preparation room. This produced overall reductions of 82.65% in excess motion, 75.49% in excess transport, and 60.66% in excess inventory. Furthermore, more than 45 min of preparation time were saved due to the reduction of non-value-added time. The challenges and barriers, as well as, areas of future applicability were also investigated. This case study provides practitioners valuable insights into the applicability of the Six Sigma framework for Lean implementation in a primary education setting. Further, insights regarding the future applicability and benefits in the respective field are provided. Finally, the challenges and barriers, as well as, its general future applicability are discussed.

本研究的目的是调查如何在教育环境中应用精益来改进运营流程。在幼儿园的案例研究中展示了由各种精益工具的应用混合和支持的六西格码方法的应用。多种工具，如：鱼骨图；A3 报告；'5 为什么'; 过程映射；废物分析；和 5S 等导致了准备室的重组。这使过度运动总体减少了 82.65%，过度运输减少了 75.49%，库存过剩减少了 60.66%。此外，由于减少了非增值时间，节省了超过 45 分钟的准备时间。还研究了挑战和障碍，以及未来适用的领域。本案例研究为从业者提供了关于六西格码框架在小学教育环境中实施精益的适用性的宝贵见解。此外，还提供了有关各个领域的未来适用性和收益的见解。最后，讨论了挑战和障碍，以及它的一般未来适用性。
