When an application is being designed for a company, windows interface standards can be superseded by

The company's interface standard.

Explanation:

Before the implementation stage in the software development life cycle is the design of the software without the use of codes, but graphical tools and skills, following standardized design interface patterns.

The design interface process involves producing a low fidelity interface design called wireframing to give the description of the component position in the application, and a high fidelity interface design like prototypes to show the functionality of the application.

The design follows the standard of the platform on which the application would be used like iOS standards for apple application, windows standards etc. But a company's standards supercedes all other standard.
