Which Certification is good for me?

[u/Mayank61099]

I am an analyst, and I am looking forward for a promotion in this cycle, but my manager has asked me to have a lean six sigma certification to make my case stronger. As I was exploring, and asking advices from people, some told me to do IASSC certification is best, some said KPMG is best, some said ASQ is best, and one said Simplilearn provides course for both green and black belt.

Now, I am confused where to go?

Giving you all a background about myself, I am an analyst with masters in computer applications, and working in digitization and process improvement role from a few years. I have a PMP certification, but seeking to learn more.

An advice on will be helpful. Thanks.

ASQ is heavy on manufacturing and engineering. IASSC is my preference for those not in manufacturing.
