Teams own problems, not products
This idea was brought forward on Twitter (@DynamicWebPaige), where "teams should consider themselves as owning problems, scenarios, or use cases, not owning products. That reframing is because a product, language, or any other thing can be transient, but the problem generally is not transient.
Sometimes, it's easy to conflate the two because of the tight linkage or the lineage of the product, as well as the evolution of that product as the knowledge about the problem changes. This is maybe a little bit like the Ship of Theseus where you keep changing the "product" to match the problem such that over time none of the original "product" remains. You're still solving the same problem, so focus on solving that versus building a product.
