The study aimed to assess the impact of implementing Six Sigma practices on teaching effectiveness. This exploratory research, conducted at the University of Okara, centred on teachers from various departments. Qualitative data was gathered via semi-structured interviews and analyzed using thematic analysis. The findings revealed that faculty members were unintentionally addressing three phases (define, measure, and analyze) of the Six Sigma process due to a lack of awareness. Students were knowledgeable about their educational standards and rights, and their issues were addressed when communicated. However, the remaining two phases (improvement and control) of Six Sigma were neglected by university teachers, with quantity taking precedence over quality. Teachers acquainted with Six Sigma practices demonstrated greater teaching effectiveness. The study recommends raising awareness among teaching staff about Six Sigma practices and ensuring their implementation for better outcomes. Expanding the data collection scope for result triangulation is also suggested.
