It makes our stakeholders and clients feel comfortable to see a complete feature that works and looks great like it’s supposed to be in the final product.
A complete feature gives pieces of mind that we are making progress towards a shippable product.
In reality, a feature is done when it proves its value of existence beyond technical and aesthetic implementation.
No matter how robust the feature is or how beautiful it looks, we have to kill it if it doesn’t produce any value for users.
In an ideal world, we would only be asked to build a feature that is already proven to work for the users.
But in reality, the development process is a part of discovering, evaluating, and delivering value to users.
The best way to achieve the highest ROI on our resource is to focus on why the feature exists, not how it exists.
