Strengths & Limitations

Strengths

  • +Provides a structured and systematic approach to comparing complex systems.
  • +Highlights trade-offs that might not be immediately apparent through other analysis methods.

Limitations

The functional decomposition might be too high-level and not capture all the detailed engineering challenges. The comparison might also be subjective depending on how functions are defined.

Reliability & validity

The reliability of the method depends on the consistency of how functions are defined and decomposed. Validity is supported by its grounding in established engineering design principles and its ability to reveal meaningful trade-offs.

Think critically

How might the subjective nature of defining 'functions' impact the comparability of different WEC archetypes using this method?
