Measuring and the rough opening
A unit only fits properly if the opening is right: correct size, square, and with a level sill. Where an existing opening is out of true, it gets corrected before the new unit goes in.

The Detail
What Window & Door Installation Involves
Sealing, flashing and insulating
Sill pan or flashing beneath, correct lapping so water is shed outward, low-expansion foam or backer rod around the frame, then sealant. This is what separates a window that performs from one that merely closes.
Trimmed out both sides
Interior casing and exterior surrounds finished off, so a new window or door looks like part of the room rather than a recent repair.
