After years of building and advising service design teams, I keep seeing the same three mistakes:

1. Hiring for craft instead of systems thinking.

Most orgs hire service designers who are great at journey mapping but can't connect their work to business outcomes. The best service design teams have people who think in systems — they see how a single touchpoint ripples across the entire customer lifecycle.

2. Treating service design as a project, not a capability.

You don't "do" service design on a project and move on. The organizations winning right now embed service design as an ongoing capability — integrated into product, ops, and strategy. If your team only gets pulled in for "big initiatives," you're leaving massive value on the table.

3. Not measuring what matters.

Customer satisfaction scores are table stakes. The best service design teams track time-to-value, cross-channel coherence, and service recovery rates. These metrics actually move the business and give your team credibility with leadership.

If you're building or scaling a service design function, these are the traps to avoid. We go deep on all of this inside the Service Design Network.
