what it means
When several explanations fit the facts, prefer the simplest one — the one that needs the fewest assumptions.
How Occam's Razor works

Occam's razor is a debugging rule for business: check the simple causes first, and prefer simple solutions that are easier to execute and maintain.
where it comes from
Named after William of Ockham, a 14th-century English friar and logician, who argued that one should not multiply entities beyond necessity.
