Are there any particular design methods that help while designing UIs that
are available via multiple channels. e.g. items can be bought using an a)
online store; b) over the phone; c) or ordered using an in-store kiosk.
How can I create UIs that provide a consistent user experience? Each channel
will be implemented by different teams. What kind of design documents can be
created to communicate the design to various teams etc. If a particular team
runs into a problem with a design, how can changes be made to each UI
channel to reflect changes (if any)?
