Spiral Lifecycle Increment Modeling for New Hybrid Processes

摘要: The spiral lifecycle is being extended to address new challenges for Software-Intensive Systems of (SISOS), such as coping with rapid change while simultaneously assuring high dependability. A hybrid plan-driven and agile process has been outlined these conflicting the need rapidly field incremental capabilities. system dynamics model developed assess support project decision-making. It estimates cost schedule multiple increments a that uses three specialized teams. considers changes due external volatility feedback from user-driven requests, dynamically re-estimates allocates resources in response volatility. Deferral policies team sizes can be experimented with, it includes tradeoff functions between timing within across increments, length deferral delays, others. Both simulation are evolved on very large scale other potential pilots.
