The article does a great job of cutting through all the noise.
Highlighting here because it is relevant: certification is about sales.
I’d only do it once you either:
1) you spend much more time filling out questionnaires than the time/investment needed to get certified (note, they’ll still ask you to fill out questionnaires though)
2) you want to go after companies that actually care about this (banking, government). Even then, these will have shortcuts through procurement that will lower requirements (ie: innovation projects, small ticket items)
