Sounds good.
In reality, it is all about progression. If you are not progressing with intensity (weight lifted) then you should be progressing with some other variable such as volume.
With beginners, a natural progression might be something like this:
Weeks 1&2 - sets of 2x5
Weeks 3&4 - sets of 3x5
Weeks 5&6 - sets of 4x5
Weeks 7&8 - sets of 5x5
That is the most volume that I would use. After you reach weeks 7&8 you work on increasing intensity and leave volume stagnant. Ride out strength gains until they too, plateau. From there, you have many options such as strategic deconditioning or deloading.
Obviously you are not going to fall into this exact picture, but you get the idea.
