Site-Wide Standards

As I mentioned earlier, it may be up to someone other than the IA to set and
document the standards being used. However, it can also fall into their jurisdiction
because the IA should at this point have a deep understanding of how the site and
its interface work.
Whether managed by your IA team, design team, or content team, it is always
helpful to set site-wide standards. These are the various production guidelines
that the entire team will follow as it works through the production concerns of
the site. Setting these standards can be the job of the lead designer, the project
manager, or can be done by a full team.

Some of the concerns for which you should study your site and create a standard
include the following:
Code
Code commenting
Colors
Directory structures
File naming conventions
Graphic formats
Maintenance list
Accessibility guidelines
Content guidelines
Team members and roles
Policies
