- KonferenzbeitragCan boundary objects mitigate communication defects in enterprise transformation? Findings from expert interviews(Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Abraham, Ralf; Niemietz, Hella; Kinderen, Sybren de; Aier, StephanInappropriate communication is a major threat to enterprise transformations. While enterprise architecture (EA) models may be helpful to support communication, these models are often tailored to the needs of specialists like enterprise architects. Based on empirical data from 12 expert interviews, we analyze how EA models can become boundary objects that span knowledge boundaries and alleviate communication defects among heterogeneous stakeholder groups in enterprise transformations. We contribute a framework that maps six communication defects to three knowledge boundaries and to 12 boundary object properties as a foundation for future EA model design. Our findings also indicate that EA models alone are not sufficient for overcoming communication defects, but that facilitators like architects are needed in addition.
- ZeitschriftenartikelCrossing the Line: Overcoming Knowledge Boundaries in Enterprise Transformation(Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Abraham, Ralf; Aier, Stephan; Winter, RobertEnterprise transformations are fundamental changes in an organization. Such changes typically affect different stakeholder groups (e.g., program managers, business managers) that exhibit a significant diversity regarding their members’ knowledge, goals, and underlying assumptions. Yet, creating shared understanding among diverse stakeholder groups in transformations is a main antecedent for success. The paper analyzes which properties of enterprise architecture models contribute to syntactic, semantic, and pragmatic capacities which helps to create shared understanding among stakeholder groups involved in enterprise transformation. The differences among stakeholder groups are assessed through the lens of knowledge boundaries, and enterprise architecture models are assessed through the lens of boundary objects. A research model is developed and empirically tested that describes which boundary object properties are required to overcome three progressively complex knowledge boundaries – syntactic, semantic, and pragmatic. The findings show which boundary object properties contribute to a respective capacity needed to overcome each of the three knowledge boundaries. Specifically, the results show that for (1) a syntactic capacity, concrete and modular enterprise architecture (EA) models are helpful; (2) a semantic capacity, visual EA model properties are relevant, and (3) a pragmatic capacity, broad stakeholder participation is conductive.
