Should be co created? Who should be involved in them up? Very good question. And here again, in trail mode, a few answers that I have for you. It depends. If you are a solo entrepreneur, if you are running a service as your own in solo, It can be quite useful to co create them, but it's not a must.

Because you're running the service, you're running your tiny little organization alone, so you're already enough to make these principles happen. But if you're part of a company, and if you're part of a team, then the answer is a bit different. Then you definitely should involve people in the co creation of your, the service design principles you'll follow for your service product or organization.

Because it's a good way to engage the team, and it's also a good way to, be sure that the principles you think are important are really important for everyone. Again, as always, you will see, it depends, but solo entrepreneurs, not absolutely needed. There is benefits for people who are working in organization, big organizations and definitely do it.
