How to express 'unneed' of something?

Question

For example, method 1 of doing something (say A) requires something else (say B). And I invented method 2 to do A but without the prerequisite of B. I can say:

The disadvantage of method 1 is its requirement/need of B.

Now I want to introduce my method by saying

the advantage of my method 2 is its (the phrase).

What should I put in there to represent the meaning of "no requirement/need of B"?

I don't choose to say "the advantage of my method 2 is that it doesn't require B" because I want to also introduce other advantages, like "the advantage of my method 2 is its speed, efficiency, and … ". What should I put here?

Answer 1

The word "obviate" may sound a bit out of place, but you could try this.

"The advantage of my method 2 is it obviates B."

or

"The advantage of my method 2 is its speed, efficiency, and obviation of B."

You also have the option of this semi-quick-and-dirty line:

"The advantage of my method 2 is its speed, efficiency, and lack of B as a requirement."

Answer 2

The advantage of my method 2 is that it...

• makes "B" redundant (or superfluous).
• moots "B" (or makes "B" moot).
• eliminates the contingency on "B".
• takes "B" out of the picture.

Answer 3

I think the natural choice is elimination. You could use its elimination of B, its elimination of the need of B or its elimination of the prerequisite of B. But they are all too wordy.

If you want a concise sentence, I recommend to rephrase it, and use either fewer steps or fewer prerequisites instead.

The advantage of my method 2 is its fewer steps, speed, efficiency, and … ".

Answer 4

Method 2 removes the requirement for B and has the advantage of ....
