Team Vision for System-Level Design Phase

Our team planned to develop high level concepts, improve benchmarking and develop high level knowledge of our subsystems. Our team has met these goals as displayed below.

Functional Decomposition

The functional decomposition is a high level view of all possible options.

The selection criteria for the best option include:

  1. Cost
  2. Simple/Intuitive to use or operate
  3. Safe for children
  4. Quality of product
  5. Fulfill Purposes set by CR and ER
  6. Size and Weight
  7. Time table/ability to complete on time
  8. Able to be easily reproduced
  9. Able to safely stack
  10. Aesthetics

Morphological Table

The morphological table below visually shows options for aspects of the project as shown in the functional decomposition.
