The spiral model combines iterative development with a sequential linear approach and places strong emphasis on risk analysis.

### Why this is right The spiral model combines iterative development with the sequential linear approach and gives risk analysis strong emphasis. Its cycles include planning, design, construction, and evaluation. ### The concept A spiral project repeats development activities as it progresses. The risk emphasis helps teams identify potential problems early, making the approach appropriate for high-risk projects. The same risk-dependent structure can make it costly and unsuitable for smaller projects. ### Terms - **Iterative development**: Repeating development work in successive cycles. - **Risk analysis**: Examining uncertainties that could affect project outcomes. ### Remember Spiral means repeated cycles with explicit attention to risk.
