It does not matter how much is reported about readiness of products, portals and the like.

Yes you argued with product management about the product readiness, you cautioned management about what the current status "really" means. Will it be understood? No. Because it is in the abstract, in the Powerpoint, in the report. It is not the real thing.

The "real" understanding starts when you accompany the stakeholders on a customer journey, which is easier with digital products. Then it becomes better understood.

Beware, the product has to have a certain maturity, because extrapolating as a non-product owner is very very hard. And the visual design has to be right as well. Not good enough, means there is no trust in the substance.

Concrete beats abstract. Don't talk about the things, show them or work directly on them.
