How is service design different from Lean and Six Sigma and how could young professionals decide which certification they should go for between Lean Black Belt, Six Sigma or Service Design? So let me be clear. I'm no Six Sigma expert. I'm not certified in this kind of stuff. So what I'm saying here is just my basic understanding of These this world.

So I asked around on LinkedIn and I got this answer from Marceline Reinhart, who is a service designer and who has a bit of experience with both of these worlds. And she says, we believe the human centricity of design thinking is key. You focus more on qualitative than quantitative and behavior before interoperability.

So she thinks that's the big difference between Six Sigma and Service Design. To be clear, to me, I will just go back to the kind of history part of where these two fields come from. Six Sigma, from my understanding, again, comes more from manufacturing. So it's awesome for improving processes. And That's really big trends that I see in all these certifications.

One other thing that is quite lovely, and that I see as something very powerful, is that Six Sigma has like these levels, in Karate, where you have a yellow belt, black belt, et cetera, that proves that you are progressing in your practice. And that's something that is quite useful, I think, and that is quite helpful.

For you if you have an imposter center because you see that you're making progress, but also for recruiters, maybe service design obviously comes from more the marketing and design work. Historically, it's really a market. It has been invented by someone who was a marketer, so it's awesome to understand people and their needs.

So that's really where it comes from. And one thing that I really like about Service Design is that it matches those not just people like end users, but people who are partners, the stakeholders, the employees, and also the end users. So this kind of mixes all of these people together, which is something that I find quite lovely.

But to be clear, a lot of these different Fields B T X, lean Six Sigma. Service design, we use a lot of similar tools, so you can't make a big, a bad choice. I would say whatever you choose, I think you'll get a lot of tools and maybe the starting point, the history is a bit different and the language might change.

To answer, should you use, should you go for one or the other, I would say choose the one that looks better in your CV. It's just that. Which one will get you more recognition? Especially if you are starting your career, the question here is if everyone has... Lean certification, maybe, might be smart to have one which is something different to to stand above the crowd.

Or, if you're really insecure and you say, hey everyone has this service design thing I also want it. Okay, cool. Then do it like that. So it really depends. But I think if you choose Lean, if you choose Service Design, that's not the big question. The big question is, Practice, observe, and learn from others.

Whatever you choose, you will learn, obviously, a lot of good things.
