A bit of context
Capital One is an American bank that is pretty well known in the field of Service Design for its deep focus on the customer experience. Back in 2019 the bank bought the design firm Adaptive Path. Adaptive Path was a consultancy that was pretty active in the community: it shared loads of quality articles about UX design, Service Design and customer experience and organized some pretty insightful conferences.
The image I'm showing here isn't really a process, but it's rather a map that shows what tools and methods can be used at the different stages of a Service Design process. But by doing so, this map also reveals what are the big steps of a Service Design project for the design team at Capital One.
What I like about it
I particularly like this Service Design process because it helps answer the question that many people starting in Service Design have: What tools do I use when and in what order? What do I start with?
For each stage of the process, between 5 and 6 tools and methods are shortly presented. And for each method a tiny sentence explain what the tool is. I think this can be really a good help for many people out there. 5 or 6 methods isn't a too overwhelming number and the short sentences make it possible to see quickly what tool you should explore in more details.
Go deeper
I found this poster on a blog article called "Service Design Tools & Methods" on the Design Team blog of Capital One. There you'll find more details and will get the possibility to download a high resolution version of the poster or get a more "mobile-friendly" version of the design.
