My two cents

In my free course, "What is Service Design?" I summarise what a service designer does in these four activities: 

1. Research: Understand what people want or need

2. Sense-Making: Summarize what they have learned

3. Ideation: Come up with 100 new fancy solutions

4. Prototyping and testing: Build new solutions for testing and help implement them once they are tested

Outside of these specific service design tasks, service designers also have to do the usual tasks that any other knowledge worker does, like for example do project management, share their ideas and onboard others to understand them better. 

The AI answer

I've asked this question to ChatGPT, and here is the raw answer it gave me. Take it with a grain of salt.

A service designer is a professional who designs and improves services for organizations. Service design involves identifying the needs of customers and stakeholders, and creating solutions that meet those needs in an efficient and effective manner. Service designers may work in a variety of industries, including healthcare, finance, retail, and government. They may be responsible for designing services from scratch, or improving existing services to better meet the needs of customers and stakeholders. Some of the tasks that a service designer might perform include:

• Researching customer needs and preferences

• Identifying opportunities for service improvement

• Developing and prototyping service concepts

• Testing and iterating on service designs

• Communicating design concepts to stakeholders and team members

• Implementing service designs

• Measuring the success of service designs Service designers typically have a background in design or a related field, such as psychology, sociology, or business. They may also have training in user-centered design or service design methods.
