Manufacturing systems adoption in Ugandan textile plants has been a topic of interest for improving productivity and competitiveness. A randomized field trial was conducted to assess the adoption rates of various manufacturing systems in Ugandan textile plants. Data collection involved surveys and direct observations over a period of six months. The analysis revealed that approximately 45% of participating textile plants adopted at least one new manufacturing system, with significant variation across different plant sizes and types. The randomized field trial provided valuable insights into the adoption dynamics of manufacturing systems in Ugandan textile industries. Further studies should explore the long-term effects and potential barriers to the widespread adoption of these systems.
