Individuals are autonomously designing, creating, and operating their own complex, idiosyncratic information systems. These systems are designed in an experiential and emergent way. Situations in which individuals connect to organizations establish binding, system-to-system interactions described here as a bindpoint. A bindpoint is a revised joint context created when two information systems connect. In order to accommodate individual information systems into the design of organizational user interaction, design principles for system-to-system interaction are required. Growing individual technological autonomy requires and creates dynamic bindpoints where formerly there were relatively static user endpoint interfaces across an air gap. Useful design principles for these bindpoints are needed to enable the organization to securely locate its enterprise system bindpoints in relation to the individual system endpoints. One promising approach is the use of a metalogic as a foundation for an explanatory design theory. This theory satisfies the conditions of emergent complexity created by bindpoints while serving requirements for security.
