Service designer

What does a service designer do?

A service designer looks at how people experience a service from start to finish and redesigns the parts that fail them.

The scope covers apps, websites, branches, call centres and the staff processes behind them.

In Singapore, service designers work in banks, insurers, telcos, healthcare groups, government agencies and digital product teams. Some sit in an innovation or design team. Others join a product team or a consultancy that serves several clients.

You work with UX researchers, UX/UI designers, product managers, engineers, operations staff and business owners. Your main outputs are journey maps, service blueprints, prototypes and workshop results that these teams use to decide what to build.

What the work involves

• Interview customers and frontline staff to find out where a service causes confusion or delay.
• Map the customer journey and draw a service blueprint that shows the staff actions and systems behind each step.
• Run workshops with business, technology and operations teams to agree on problems and generate ideas.
• Build prototypes in a tool such as Figma and test them with real users.
• Write up findings and design standards, and present recommendations to stakeholders.
• Coach junior designers and review their work.

1. What is the difference between a customer journey map and a service blueprint, and when would you use each?

   What a good answer covers

   • A journey map shows the customer's steps, thoughts and emotions.
   • A blueprint adds frontline actions, backstage processes and supporting systems.
   • Use a journey map to find pain points and a blueprint to find the operational causes.
