Bring design and development together from the start
Early collaboration gives designers and developers the opportunity to resolve requirements before a direction is signed off. Developers can identify technical limitations, suggest feasible alternatives and help account for practical accessibility considerations such as colour contrast and different input devices. Designers can in turn stay involved during development to help protect the intended experience and learn from technical constraints.
This approach is especially useful when a digital experience must work across devices and for different users. Treating inclusion as a late-stage check can leave too little time to make meaningful changes. Bringing relevant technical perspectives into the design process makes constraints visible earlier, when the team can work through them together rather than treating them as a handoff problem.
