Systematic Approach having a systematic way of eliminating possibilities
Design Process Define the problem; Brainstorm; Research and Generate Ideas; Criteria and Constraints; Explore possibilities; Select an approach; Develop a Design Proposal; Make a Prototype; Test the Design; Refine the Design; Create it; Communicate Process and Results
Mechanical Core Technology motion produced by mechanical parts
Electrical Core Technology production from electrical energy
Electronic Core Technology small amounts of electricity to process
Structural Core Technology putting together parts for support
Fluid Core Technology using fluid to apply force or transport
Optical Core Technology using light to do work
Thermal Core Technology getting work from heat energy
Biotechnology Core Technology altering organisms and biological processes
Materials Core Technology producing, altering, and combining materials
Criteria desired features of the product or system
Constraint relate to the limitations of the design
Financial Criteria/Constraint cost-benefit ratio for the device
Production Criteria/Constraint the resources available for the device

Concurrent Algorithmic Instructions 2 instructions done at the same time
Syntax Error a grammar error; program will not run but give an error message; usually easy to fix
Logical Error an error in design; will run but give wrong results; most difficult to fix
Run-Time Error an execution error; will run but give an error message; not always easy to fix
