Software is created once. If it runs on more than one computer, it&#x27;s just copies of the actual result of that one time creation. If it&#x27;s improved with new features, then that&#x27;s a new unit, itself created once. The effort goes into the creation of the one thing, not the copies. Version 1.1 is not version 1.2.<p>This observation is often used to point out that &quot;software is different&quot; from cars and other hardware. Cars and hardware have lots of chances for defects, but software copies are essentially perfect. Assembly line products are not copies like a package or disk is a copy; each finished unit has lots of effort in it.<p>But if you still want to use the hardware example, find what the equivalent products are. A lot of effort goes into physically assembling a car, and then the car cranks out transportation.<p>A lot of effort goes into physically assembling a software team, and then the team cranks out software.<p>And while of course there are profound differences between a car an a human team, it might be useful to put engineering resources into designing and producing a team.
