Designing Informal EAM Interventions – A Complementary Approach for Managing Enterprise Architecture Complexity

Although Enterprise Architecture Management (EAM) is a mature discipline and widely adopted in practice, surveys indicate effectivity barriers that, at least partially, appear to be a consequence of local decision makers’ non-compliance with enterprise-wide architectural guidelines. Several recent contributions aim at extending the portfolio of EAM interventions by applying informal control mechanisms. Although promising to extend EAM effectivity, informal interventions are apparently not much utilized in EAM practice. Based on the assumption that a comprehensive presentation of design knowledge for informal EAM interventions would support more widespread adoption, this paper integrates existing knowledge components to a coherent design approach. The proposal covers theoretical justification, conceptual foundations, a taxonomy of generic informal interventions, a catalogue of derived EAM intervention types, and a process to systematically instantiate and evaluate situation-specific informal interventions. Two Action Design Research projects in large companies are summarized as evaluative evidence for the potential that comprehensive in-formal intervention design has for improving EAM effectivity.
