As per my understanding, "introduce" means informing the team of upcoming features. Is it wrong to do so? It gives the team some time to think about it, and come up with a plan to discuss or even refine the PBI at the PO's discretion.
Yes, the team should start working on it in the next sprint(s) based on priority - but waiting till the next sprint planning to introduce the said features can delay the solution design and development.
Any thoughts on this please?
