Service design is the activity of planning and aligning an organisations resources (people, assets, and processes) to refine a service, and directly improve both employee and user experience.
Identifying how to deliver against audience expectations
A service design approach should be considered when you are looking to improve an existing service or create a new one.
It can also highlight issues with underlying processes, skill sets, or non-digital barriers to delivery. A good service design process can eliminate unnecessary expenditure where it can be shown existing solutions will deliver the right outcomes, or a digital solution is not needed.
The real benefit of following service design principles is it combines the organisational needs of delivering a service with the human experience of that service.
