Abstract
In this chapter, we explore the nature of migration as it applies to crossing system-retirement life cycle boundaries gracefully, intending to inform purposeful design of would-be, long-lived, always-effective enterprises, and the systems that support them. We use previous work on agile systems and enterprises to define migration as the crossing of a change in basic infrastructure, be it technical, organizational, or strategic. We consider the classic view of the system life cycle and highlight its limitations in a rapidly changing world. We analyze two successful and contemporary large-scale migrations and illuminate the factors that facilitated their success, contributing toward a pattern language for agile-system architecture in the process. Finally, the lessons of the analysis are suggested as potential informants for force transformation in the US military and adoption of service-oriented architectures in the enterprise.

Response Ability Principles encompass research initiated at Lehigh University’s Agility Forum in the 1990s and later detailed in Response Ability (Dove 2001).

Dove (2007) distinguishes agile systems as reconfigurable (class 1) and reconfiguring (class 2). The drag-and-drop/plug-and-play pattern is most naturally associated with class 1 (reconfigurable) agile systems, as the four integrity responsibility elements of the active infrastructure are typically peopled rather than systemic.
