• The term “modus operandi” is a Latin term that describes the habitual mode of action of a person or group, which is a discernible pattern.

  • Modus operandi (usually abbreviated “MO”) is mainly used to discuss criminal behavior and is often used by professionals to prevent future crimes.
  • Modes of action may change over time, in particular through adaptation to experience, but also due to changing values.
  • Studying patterns, not just criminal ones, can help people who study them and pay attention to them, for example, investors.
