Is it proper to use “would” here?

Question

I'd like to say something like: I'm going to change the code in the future, according to this requirement.

Here is my version:

This code would need to be modified to satisfy this requirement...

I don't know if it is proper to use "would" here(or "will"?), or any better expressions?

Answer 1

"Would" suggests conditions necessary for a state to occur or an action to be performed.

This code would need to be modified given this requirement.

"Will" may be used in the same manner. (acknowledgment to Barrie England for this point)

This code will need to be modified given this requirement.

"Will" is also used to express a determined future outcome.

This code will have to be modified to satisfy upcoming requirements.

Answer 2

"Would" implies that the requirement is in flux, ie. You would use "would" only so long as you are discussing whether to place the requirement. Eg.

If we were to place this requirement, the code would need to change

or

Given this requirement, the code needs to change

Answer 3

"Would" seems needless here. For me I will say:

This code needs to be modified to satisfy this requirement...

Answer 4

What you have is fine if what you mean is This code would need to be modified if we wanted to satisfy this requirement.

If there is a greater probability that those concerned will want to satisfy the requirement, it would be more appropriate to write This code will need to be modified to satisfy this requirement, which is another way of saying This code will need to be modified if we want to satisfy this requirement.
