Design teams need to find a balance between working together and apart, depending on the stage of the design process. They should not "throw things over the wall" and instead communicate throughout the design and development process. Building cross-functional communication skills is crucial, but can be challenging, especially in teams with tension or past unsuccessful attempts at collaboration. To overcome this, it's essential to start by incentivizing the change, reframing large changes as low-risk tests, and running pilot programs to prove out benefits. Designers and developers should speak the same language and use terminology that aligns with their shared goals of building high-quality software faster. Ultimately, driving adoption requires investing in internal training, workshops, and communication, creating a breadcrumb trail of documentation, and making the value of the design system clear to all team members.
