pure::variants for IBM DOORS® and DOORS Next Generation® is an integrated solution that enables systematic Variant Management and reuse of requirements across multiple systems and DOORS Requirements Modules. It is a certified Ready for Rational Solution ensuring maximum interoperability and ease of use.
Modules in DOORS are linked with pure::variants feature models - these model what is common to all products in the product line and what varies between products in the product line. Additional
relations and dependencies between requirements that have not been represented in DOORS are then modelled in pure::variants. From these models individual product variants may then be created
using pure::variants. The results are stored in DOORS to record which requirements map to which variants.
