Features

A feature is any significant aspect of a website from the large (e-commerce) to the small (print friendly pages). Since most every website feature can be designed/implemented in multiple ways as well as there can be a custom advanced version or a basic ‘out of the box’ one, it’s important to specify how a feature will be implemented.

Takeaway
Make sure the website features that comprise your website have been defined properly at the beginning of a project, so there are no surprises as to how it works and how much it costs.
