It can use waterfall type planning and discovery up front to provide the level of certainty required in dangerous installations but allows for rapid iteration once certain variables are known. ^a8ab51 > Here is a peer-reviewed paper from NASA arguing for The Business Case for Spiral Development in Heavy-Lift Launch Vehicle Systems > The Spiral Development process is now being widely used for large Government program acquisitions and lends itself to the project described here. The main advantage of this concept is that it builds on existing capabilities and assets, as opposed to starting up a “new sheet” vehicle program from scratch. Spiral Development designs recombine existing assets in new configurations to function in extrapolated operating conditions. > Certain organizations still require up-front planning due to the sheer scale of their deliveries (no one is jumping into Sprint 1 to start building a new data warehouse without some planning…) `
