Hansei is a Japanese word that means introspection or observation of one's reflection. The word “Han" means to change or turn over, while "Sei" means to look back upon and examine oneself.
Hansei is a systematic approach used to recognize and contemplate committed mistakes in the project life cycle that helps understand misconception, inaccuracy, failure, and errors. It helps organizations comprehend appropriate action and how it can be improved to avoid recurrence of the issue. Hansei is commonly performed after projects are completed, during year-end reviews, or as part of employee self-assessments.
