Maintain access to a specialized architecture add-on without overcommitting budget or seats. IBM Rational System Architect for NAF Add-On with Software Subscription and Support is a fixed-term license for 1 authorized user on PC, with a 1-year validation period and subsequent pricing under Passport Advantage. It is designed for teams that need a defined entitlement window and a clear renewal path. This licensing model is well suited to organizations that manage software as a planned operating expense. The 1-year term helps align access with project cycles, annual budget reviews, or support commitments, while the authorized-user model keeps usage tied to a named individual. Windows support and PC platform compatibility make it straightforward to fit into standard enterprise desktop environments. For procurement, the appeal is precision: one user, one year, one licensing program. For IT, the benefit is predictable administration and a supported software posture over the term. When a team needs the NAF add-on as part of a controlled deployment strategy, this license provides the right level of access without excess complexity.
