Requirements are intended to propose changes or additions
to hardware or software products. Requirements are created by the Requirement
Manager with input into a product's definition. Requirements are the
initial point at which a request is analyzed.
New customer requirements
are defined as candidate requirements and related
to the model for commitment. A single candidate requirement can be defined
as a structure of requirements (sub requirements). Candidate requirements
are related to the candidate feature and outline the requirements that
satisfy that feature.
