I mentioned UI because of the parent comment (about hooking UI up to a sub-component).

The core idea I was trying to get across is that until a feature is working and in front of a customer (or stakeholder), it's essentially in limbo because you don't know if you've built what they wanted. Maybe there was a miscommunication, maybe they find the feature confusing, maybe they've changed their mind. The goal is to get feedback as soon as reasonably possible.

eg: A stakeholder (or customer) requests feature X, and everyone agrees it's a good idea and we should to work on it right away. The dev team could spend 2-4 weeks writing excellent behind-the-scenes code that's not hooked up to anything, or you could spend 2-4 weeks on holiday. Either way, you've given stakeholder the same thing: No new feature.

If you're confident that you know exactly what it is you want to build then you don't need Agile, scrum or sprints. Scrum isn't supposed to be waterfall with arbitrary reviews every 2 weeks.
