Managing Constraints – Two Approaches

Relate each Requirement to all applicable top-level Components and manage budgeting via parameters

Each level of physical architecture has separate Requirements

specifies (specified by)

Requirement [mass] (Originating)

Component (System) param[mass]=X(sys)

Requirement [mass] (Originating)

refined by (refines)

built from (built in)

specifies (specified by)

Requirement [mass] (Derived/Segment)

Component (Segment)

Component (Segment) param[mass]=Y(segment)

built from (built in)

refined by (refines)

built from (built in)

specifies (specified by)

Component (CI) param[mass]=X(CI)

Requirement [mass] (Derived/CI)

Component (CI)

Remember that Components are implementation requirement specifications
