This page is designed for the introduction of new concepts, design processes, brainstorming, etc.

Team,
Given the comments onthe discussion tab, let's figure out a better place to put stuff like this.
Here is a slight variation on the Pugh Charts above (a.k.a. a "decision matrix").

  1. Organize your blank chart as you do normally (like above)
  2. Set ALL the values of the first concept to zero
  3. Compare the next concept to the baseline using zero if the concept compares roughly the same,
    +1 if the concept is significantly better for the robot than the baseline
    -1 if the concept is significantly worse
  4. Do the same for all other concepts
  5. Sum rows as above
It is very hard to say that a concept is good, bad or indifferent without something to rate it against.
The main advantage of this way is you now have an easier job rating your concepts because you have
something else to compare them to.

It also helps to make notes in the cells or footnotes to point out specific attributes or extremes. See
my italics below.

This example table below is purely ficticious (and hopefully kind of humorous...)

0 [our prototypes ended up being exactly the same weight}

Rating






1 or +1
concept is better than the baseline




0
concept rates roughly the same as the baseline




-1
concept is worse than the baseline
