PREVIOUSLY
• Engineers and computer scientists design and build the world.
• Engineers visualize the things they design as systems.
• They design and build things in a systematic way.
• They use the engineering design process .
• They become engineers and computer scientists by
• studying at an accredited university
• becoming members of professional associations
• working on projects.

* Systems

PREVIOUSLY
• Block Diagrams
• Abstraction
• Composability
• Engineering Design Process
• Overview of steps
• Identify and Define the Problem
• Requirements documentation

* Systems

WHAT IS A SYSTEM?
• a collection of interconnected components that have some function or purpose

• A system has an interface.
• Input/output

• A system has a behavior.
• Relationship between input and output.

• A system has a structure.
• The organization of its components.

SCAMPER
Substitute
– components, materials, people
Combine
– mix, integrate, interoperate
Adapt
– alter, change, re-purpose
Magnify/Modify
– change scale, shape, attributes
Put
– to other uses
Eliminate
– remove elements, reduce functionality
Rearrange/Reverse – inside out, upside down
