A new service can look excellent to designers, be technically feasible to engineers, and still be impossible for support staff to operate. A cross-functional team brings those capabilities into the same working group early enough for each to influence the result.

The team needs to combine the skills necessary to complete a useful outcome. That does not mean every person must be equally good at every discipline. The point is combined capability and shared responsibility for an outcome.

The handoffs move inside the team

A public-library team redesigning reservations could include someone who works at the desk, someone responsible for the software, and someone who understands accessibility. Instead of handing a finished design from department to department, they can identify conflicts while changes are still cheap.

That collaboration requires actual availability and decision rights. Inviting a specialist to a weekly meeting does little if they cannot contribute time or commit their department to anything. Specialists also need connections with peers outside the team so professional standards and learning do not become isolated.

Cross-functional organization trades some efficiency of grouping similar specialists together for faster coordination around complete outcomes. The right balance depends on how tightly the work is coupled and whether the team can truly finish what it starts.
