Why am I into Service Design and why should you care

First of all, I'm new to Service Design. I've always been interested in customer experience, user experience, usability and generally how does using a product or a service feel. Is it easy or do you need instructions to be able use it? Do you feel comfortable using something? Or does it make you feel awkward while using it? All of this boils down to a few simple words a friend wrote on another's Facebook post a while ago: "Even the best and most effective system is worth nothing, if the people who are meant to use it don't". This is why in my opinion usability, intuitiveness and experience are the most important concepts linked to designing products and services. And that's where my interest in service design comes from.
To this point I've come across different approaches, philosophies and tools that I qualify to be a part of or at least linked to service design. My first contact, if you can call it that, was a course at LUT. My fellow students had nicknamed it the most humanistic course at our technical university. The course was "User Interfaces and User-Centric Design" from the Department of IT. The nickname most likely derived from the methods taught on the course. Mostly based on arguments and methods derived from psychology and scientific studies researching human behavior. During the course it hit me that there is actual scientific background for all the bad user experiences I've had since then! There is a logic to how products and services should be designed, a logic to how most people experience different interfaces. 
The second time I came across service design related methods was a Lean Six Sigma yellow belt e-course. Yes, I know that lean is a different philosophy, or a toolbox, or a way of doing things, but it has many things in common with service design. The revelation I had was that efficient, simple and effective methods and processes are based on simplifying and streamlining human interactions with technical automation and everyday tools. Emphasizing the value that is being delivered to the customer not defined by complex systems models designed by experts, but by optimizing simple interactions between man and tool/process/machine.
Lastly, the third time I bumped into service design was at AHTO17-event, orchestrated by Futurice and Tekes. The events main focus was on teaching Lean Service Creation principles and methods to the participants. I realized that service design wasn't completely about mastering a whole new area of expertise, but more about taking charge of using the tools. Looking at things through the customer’s eyes and finding the methods that can be used efficiently every day in your own work. Bringing service design to your workplace, processes and decision making. The main question being: “What's the value for the customer?”
I would like to think that I'm on a journey of learning and discovery, an adventure into something new and exciting that will ultimately lead to an understanding of the principles and guidelines that form the concept of service design. My next step will be to devour this thing: This Is Service Design Thinking I would very much like for you to join me on my journey in any role; a follower, a peer, a mentor, a bystander or an occasional adviser.
