Object consistency

It’s the idea that a product is reliable and predictable. Like retention, but it’s also the relationship you have with a product despite getting upset, angry or disappointed by it.

My product management professor tied this in with “commits”. We commit to a product through purchase, by using it often and saying good things about it to people.

Phones, clothes, fridges, sinks, tvs, beds, chairs, cars, pens, and so on. Above style or even quality, it has to be easy to use. Convenience is the most reliable way to keep someone coming back.
