That's really the core of it, design isn't the layer you add at the end. It's the strategy that connects what users need with what the product is trying to solve, the bridge between the two. The same applies when the foundation, the architecture, the backend, gets built first without user experience part of that conversation. If it doesn't hold up for how people actually move through the product, you end up rebuilding it later, which costs more than including design from the start.
