Blindspots analysis
（重定向自Blindspots）
Blindspots analysis (also blind spots analysis) is a method aimed at uncovering obsolete assumptions in a decision maker’s mental scheme of the environment.
Michael Porter used the term "blind spots" to refer to conventional wisdom which no longer holds true, but which still guides business strategy. The concept was further popularized by Barbara Tuchman, in her 1984 book, The March of Folly, to describe political decisions and strategies which were clearly wrong in their assumptions.
