The Butterfly Model includes algorithms which capture behaviors of triggers, relationships between triggers, and relationships between triggers and defect types. This information is used to isolate and identify opportunities and exposures at the technical level so that explicit actions are easily defined and executed. In addition, these algorithms afford the ability to project the impact of potential exposures on specific triggers, and the activities which own responsibility for them. The links between defect types and specific process activities (high level design, detailed design, or coding) which could most effectively be improved in order to prevent the defects from being injected have been clearly established. The insight gained from this analysis has implications to schedule integrity, development costs, and product stability.
