Andrew Couldwell, Laying the Foundations Design systems bring order and consistency to digital products. They help to protect the brand, elevate the user experience, and increase the speed and efficiency of how we design and build products. They are a source of truth and a system of record for our design decisions. They hold us to high standards, keep teams on the same page, and help to onboard new team members. They document the why, when, where, and how. “ ”
