A word for organized deconstruction

Depending on the composition of what you're deconstructing you might consider either:

Dissection

the action of cutting something open, especially a dead body or plant, in order to study its structure

or breakdown

a division of something into smaller parts:

Dissection is usually used in an organic context, while breakdown might apply more to an engineering system or component.

Dissection and breakdown are good choices. I thought of dismantle.

I’m going to suggest decomposition. This suggests a deconstruction faithful to the means by which the thing is constructed, or composed.

This is a standard term.

There’s also reverse engineer.
