Root Cause Analysis Consulting Services

I help people solve problems.

In today's fast-paced world, we cannot afford to face the same problems over and over again. As an engineer and consultant, I follow a systematic and hands-on approach to help you and your team become better problem solvers. My experience in the US Nuclear Navy has taught me the significance of meeting critical deadlines and supporting complex systems. Drawing from my consulting background, I firmly believe that every problem, regardless of its size, can serve as an opportunity to learn and grow.

  • "Sarah was a terrific partner in the introduction of a systematic problem solving investigation approach and the application of this approach in the highly regulated medical device industry. She communicated a clear vision and remained committed to shared goals throughout our partnership. Sarah conducted a number of workshops and provided 1:1 coaching for students pursuing advanced understanding of the problem solving technique. She was a highly effective instructor and coach, encouraging students to be open minded, responding to their questions and challenges, and providing valuable feedback on case studies. Sarah’s engagement was both in person and virtual and she was equally effective in both settings. I am fortunate to have engaged with her in this partnership!"

  • "I had the pleasure of working with Sarah Wrenn during a multiyear project. Our goal was to change the way we manage incident investigations. This initiative moved us away from single/root cause analysis and into a systemic approach for solving problems. Systemic problem solving helped us to increase overall task reliability, and while it may have started as a Health, Safety and Environmental initiative, Sarah was quickly and easily able to engage additional facets of our business, including asset and reliability performance, quality management, etc. Sarah demonstrated a rare ability to motivate and engage a very diverse workforce, and did so with the utmost professionalism."

I would highly recommend Sarah to lead complex investigations, train in cause and effect methodology and/or mentor those wanting to more effectively lead investigations."

  • "I participated in a training session presented by Sarah Wrenn. She carried herself with an exemplary level of professionalism. Additionally, she ensured class time was used effectively and all participants were able to gain the most out of their individual experiences. Her knowledge of the concepts being taught and her ability to effectively answer the questions presented to her left me with a feeling of very high confidence in her ability to be leading such an exercise. I left with a much better understanding of how to effectively manage change in processes as well as how to identify realistic solutions to problems. I am far better equipped to handle my daily work tasks as a result of this class."
