The criteria for interfaces frequently reflect critical parameters that must
be defined, or at least investigated, to ascertain their applicability.
These parameters are often peculiar to a given type of product (e.g.,
software, mechanical, electrical, and service) and are often associated
with safety, security, durability, and mission-critical characteristics.
Refer to the Identify Interface Requirements specific practice in the
Requirements Development process area for more information about
identifying product and product component interface requirements.
