"Leverage" has real meaning. Another word for it that you might be more familiar with from software is "reuse".

Reuse is leverage. If a piece of software (function, class, module, service, tool, whatever) is used for 1 task, it's not leveraged. If it's used for 10 tasks, that means the creation of the reused thing had 10x leverage: working on that reused thing created 10 times more value than working on something that's only used once.

It's not quite that straightforward as everyone knows, there are costs to reuse (abstractions (both lowest common denominator and leakage), more dependencies, higher maintenance costs owing to risk of breakage of multiple clients, etc.). But the leverage is very often real.
