A software development process for COTS-based information system infrastructure

Modern software developers are guided by a variety of formal and informal processes that organize and control development activities across large groups of developers or multiple organizations and supply the discipline and order that was lacking in many early development efforts. The available inventory of documented process methods is limited: most process methods assume the system being built will be coded largely from scratch. The processes do not address many of the challenges associated with building systems that contain large amounts of commercial off-the-shelf (COTS) software. The infrastructure incremental development approach (IIDA) is a combination of the classical development model and the spiral process model to accommodate the needs of COTS-based technical infrastructure development
