Q

What is a trade-off analysis

A

A

determining the effect of decreasing one or more key factors and simultaneously increasing one or more other key factors in a decision, design or project.

17
Q

Steps to a trade-off analysis

A
  1. understand the requirements
  2. assign weightings based on preference of requirements
  3. establish a rating scale for each preference requirement
  4. create a list of options to address your concern
  5. multiply each options rating by weight.
18
Q

Benefits of a trade-off analysis

A
  • forces thought on what is mandatory vs what is preferred.
  • explores options that may not have been considered
  • provides documented evidence on decisions made
  • involves stakeholders, making compromises easier
