Reviewers say Modern Requirements works best for teams with complex requirements work, especially when they need one connected place for traceability, version history, compliance documentation, reviews, and handoffs. Users repeatedly praise requirement reuse, smoother collaboration across teams, vendors, and time zones, and the ability to standardize processes without losing history during migrations or mergers. It also seems to support gradual rollout well, with helpful onboarding support. Main drawbacks are occasional slow load times, search that could be more refined, and some setup, templates, and guidance that feel heavy for smaller or simpler projects.
