You've have been tasked with shipping a "schedule messages" feature (like Telegram has).
Show me (in a shared Google doc or whatever) your principal product artefact (story / BRD / JIRA ticket / whatever you call it) that will help engineers build the feature for you.
Please imagine that the Why has been proven already. The goal is now to ship it. There are two distinct stages of building a product - doing the right thing and doing things the right way. Please assume we’re doing the right thing. And tell us what might be the right way of doing it
