Smart vs. Intelligentg
Smart: Performing actions based on direct ginput of information or data
Intelligent: Performing actions based on common sense, experience, and the ability to adapt, taking context into account

Planning: System decides what the state of the environment is, what the person is doing and ho best to reacthow best to react
Response: System reacts to its environment in a contextually-appropriate manner
