Doing software development from bottom up when you need to or is this a norm?

Doing software development from bottom up when you need to or is this a norm? If somebody asked you to first build the wheels for the car before having the car at all, what would you do? First, I would question if I need to design/build 4 lug or 5 lug wheels. Then I would need to predict or ask about some details to figure out the proper offset and width for the wheels so they don’t stick outside the fenders. Now how does this car analogy apply to software engineering? First, you need to know and define the API contract. Then you would probably build a stub or mocked version of your API and you would put yourself in the shoes of the client trying to use it in cases that you can predict. Depending on the performance requirements, you may end up adding caching and other improvements. This approach is actually not that uncommon. This is actually how you would approach your team to team and microservice to microservice dependencies regardless of how well you know your consumer; it is important to maintain that discipline at the technical level but as for human communication leverage the closeness you have with other teams.
