A software development manager is taking over an existing software development project. The team currently suffers from poor communication due to a long delay between requirements documentation and fe

Agile emphasizes iterative development with short cycles and continuous stakeholder collaboration, which reduces the gap between requirements and delivery rather than creating a long delay.

Waterfall is a linear, sequential development methodology where each phase (requirements, design, implementation, testing, deployment) must be completed before the next begins. This creates a significant time gap between when requirements are documented and when features are delivered, limiting feedback loops and making it difficult to catch security issues early, resulting in more bugs reaching production.

Scrum is an Agile framework that uses short sprints (typically 2-4 weeks) with frequent reviews and retrospectives, promoting rapid delivery and continuous communication that would minimize the described gap.

Spiral is a risk-driven iterative model that revisits planning and risk analysis in each cycle, which inherently addresses security concerns more proactively than the described scenario suggests.
