Product differentiation can come from features, design, service, workflow, quality, audience focus, pricing, trust, brand, or distribution. The difference matters only when it improves an outcome that a reachable customer values.
Adding novelty is not enough. A differentiated product should communicate the advantage clearly and prove it through use, while avoiding a feature list that increases complexity without changing the buying decision.

Product differentiation is the useful difference that makes someone choose one product instead of another. It can be a better feature, clearer design, stronger service, or a closer fit for a particular group.
For example, a new notes app may enter a crowded market by making team comments much faster and easier. That difference matters only if the target teams notice the improvement and prefer it in real work.
