The system receives inputs from and exports outputs to the environment through sort of internal conversion process A permeable boundary exists between the system and its environment “Boundary Management” is a key system concept Part of the outputs is fed back to become an input and thus to establish a cycle of events which enable the system to monitor it own behavior

Project As a System
Important Concepts
Large system comprise smaller sub-systems which share the goals or primary task of larger system Sub-systems are independently work together towards the common goal Sub-systems form a hierarchy of systems System interacts with its environment, and affected by environmental constraints or influences The environment is not part of the system – it does not share the goals of the system
