Using Six Sigma to Improve B Corporation Assessment Scores

For Teagen’s internship project, I asked him to use the Six Sigma DMAIC framework to help me improve my B Corporation assessment score for my next review.

The minimum score to achieve certification is 80, and I achieved an 88.7

However, I wanted to improve my scores to show improvement each year, and make sure I don’t slip and fall under 80 (or become at risk if the minimum score is increased above 80). I set an arbitrary goal of 95, which seemed achievable at the time, but also not simple or easy.

Although the B Lab website offers suggestions on what areas to improve, they might not know what realistic improvements are most applicable to my business.

He developed a process to download the assessment score data, prioritize the opportunities, and review them for applicability.

  1. Download excel spreadsheet of completed full assessment with scores from B Lab website
  2. Calculate gap between points awarded and total available points for all questions and categories
  3. Review gap scores and find which questions will be realistically easy to improve upon
  4. Prioritize opportunities based on effort of changes and monetary considerations. Identify realistic
    areas for change that have the most points
  5. Develop action plan to change scores, once desired changes are finalized
  6. Implement plan and track progress of question improvement
  7. Rescore assessment with new answers to identified questions

Together, we agreed to work on a few actions to increase scores by 4.7 points, which would achieve a revised score of 93.3.

The entire project took only 13 hours to complete, and will be finalized during the reassessment in a couple years.
