In Organization and Decision, Niklas Luhmann presents a groundbreaking sociological theory that defines organizations as autopoietic systems composed entirely of decision communications. Moving away from classical views of organizations as mere hierarchies or goal-oriented tools, Luhmann argues they are self-reproducing entities that maintain their existence by linking past decisions to future ones. This internal process allows organizations to create a closed operational boundary, distinguishing themselves from an environment they can never truly contact but must constantly interpret. The text explores how this recursive decision-making allows for structural stability while managing the inherent uncertainty of the future. Ultimately, Luhmann suggests that organizations do not just exist within society; they order and structure it through their unique internal logic of processing distinctions.
