Interpreting Results

  1. Best Date: 01-01-2024 (OEE: 90%) - High availability, performance, and quality.
  2. Worst Date: 03-01-2024 (OEE: 62%) - Due to low availability (68%) and quality (72%).
  3. Key Problems:
    1. High down time on 03-01-2024 affects availability.
    2. Quality drop severely on 03-01-2024, defective units are produced.
  4. Suggestions:
  1. Reduce the down time through better maintenance.
  2. Quality problems - operator training and raw material checking.
  3. Target constant OEE value of 85% or higher.
