“…While EA evolution presents significant challenges to organisations (Land, Proper, Waage, Cloo, & Steghuis, 2009;Short, 2013), research on this phenomenon so far is very limited and there is a lack of understanding of how EA actually evolves, in particular on the level of architectural descriptions. More specifically, there are no empirical studies that describe or explain how EA in organisations evolves due to emergent business and IT trends such as SOA (Knippel & Skytte, 2007;McKendrick, 2010;Postina, et al, 2010;Saat, Aier, & Gleichauf, 2009;Shah & Golder, 2011). A limited number of studies have either focused on the representational changes of EA, such as changes to applications (e.g.…”

“…see Buckl, Ernst, Matthes, & Schweda, 2009;Farwick, Schweda, Breu, Voges, & Hanschke, 2012), or provided examples of EA evolution on the architectural descriptions level without considering the underlying process of evolution or what may impact the evolution (e.g. see Banerjee & Aziz, 2007;Correia & Silva, 2007;Postina, et al, 2010;Shankararaman & Kazmi, 2011;Sharma, 2013 ). The existing approaches do not clearly consider external influences on the EA planning process or changing conditions in an organisation's environment (Saat, et al, 2009).…”

“…SOA is among the top issues that organisations are trying to address using EA (Varnus & Panaich, 2009) and SOA integration into EA needs more attention (Dico, 2012). In fact, many studies explicitly argue that EA needs to evolve to address and integrate SOA (Khoshnevis, Aliee, & Jamshidi, 2009;MacLennan & Belle, 2014;Postina, et al, 2010;Sanders, Hamilton, & MacDonald, 2008;Sharma, 2013 ;Viering, Legner, & Ahlemann, 2009). Kistasamy, Van der Merwe, and De La Harpe (2012) argue that, although both EA and SOA have matured, there is a lack of understanding of the relationship between them, which has resulted in a marginal realisation of their combined benefits (Kistasamy, et al, 2012).…”

Organisations use Enterprise Architecture (EA) to reduce organisational complexity, improve communication, align business and information technology (IT), and drive organisational change. Due to the dynamic nature of environmental and organisational factors, EA descriptions need to change over time to keep providing value for its stakeholders. Emerging business and IT trends, such as Service-Oriented Architecture (SOA), may impact EA frameworks, methodologies, governance and tools. However, the phenomenon of EA evolution is still poorly understood. Using Archer's morphogenetic theory as a foundation, this research conceptualises three analytical phases of EA evolution in organisations, namely conditioning, interaction and elaboration. Based on a case study with a government agency, this paper provides new empirically and theoretically grounded insights into EA evolution, in particular in relation to the introduction of SOA, and describes relevant generative mechanisms affecting EA evolution. By doing so, it builds a foundation to further examine the impact of other IT trends such as mobile or cloud-based solutions on EA evolution. At a practical level, the research delivers a model that can be used to guide professionals to manage EA and continually evolve it.

“…EA needs to evolve and accommodate emerging trends (Jung 2009;McKendrick 2010;Postina et al 2010;Sampaio 2010;Sousa et al 2009) in order to accurately develop models capable of representing those emerging trends, concepts and relationships. Yet, EA's literature lacks empirical studies that investigate EA evolution due to emerging trends.…”

“…The Open Group (2010) defines SOA as "an architectural style that supports service orientation, and service orientation is a way of thinking in terms of services and service-based development and the outcomes of services". While many studies have argued for SOA integration within EA (Khoshnevis et al 2009;Postina et al 2010), there is a lack of empirical studies that address SOA and EA integration (Kistasamy et al 2012;Viering et al 2009). So far, there has been a lack of consensus on the form of such integration and its outcomes.…”

This paper investigates how Enterprise Architecture (EA) evolves due to emerging trends. It specifically explores how EA integrates the Service-oriented Architecture (SOA). Archer's Morphogenetic theory is used as an analytical approach to distinguish the architectural conditions under which SOA is introduced, to study the relationships between these conditions and SOA introduction, and to reflect on EA evolution (elaborations) that then take place. The paper focuses on reasons for why EA evolution could take place, or not and what architectural changes could happen due to SOA integration. The research builds on sound theoretical foundations to discuss EA evolution in a field that often lacks a solid theoretical groundwork. Specifically, it proposes that critical realism, using the morphogenetic theory, can provide a useful theoretical foundation to study enterprise architecture (EA) evolution. The initial results of a literature review (a-priori model) were extended using explorative interviews. The findings of this study are threefold. First, there are five different levels of EA-SOA integration outcomes. Second, a mature EA, flexible and well-defined EA framework and comprehensive objectives of EA improve the integration outcomes. Third, the analytical separation using Archer's theory is helpful in order to understand how these different integration outcomes are generated.
