Fit for Purpose Enterprise Architecture

Today’s enterprises are confronted with an ever-changing environment demanding continuous (digital) transformation. Currently enterprise architects tend to guide these changes with so called \u27one size fits all\u27 architectural approaches. However, tuning such approaches to a variety of change situations is difficult. There is a call for a more flexible instrument among practitioners that is designed to be tailored to the context of a specific situation. Such fit for purpose enterprise architecture approaches have the potential to play a key role in the current times of digital transformation. In this paper we present the first steps towards a situational enterprise architecture approach that is based on differentiating between subsystems within organizations, by defining which characteristics of subsystems are relevant to determining the correct enterprise architecture approach

Adaptation of enterprise architecture efforts to an agile environment

Agile ways of working have become mainstream, with many organisations practising a form of agile. Agile maturity among those organisations differs. In a research conducted by VersionOne Inc. (2016), 82% of the participating organisations stated to be at or below the level of ‘still maturing’. Existing agile and architecture methods have begun to incorporate some aspects of each other, with agile methods including architecting, such as the Scaled Agile Framework (SAFe), and architecture frameworks such as TOGAF (the Open Group Architecture Framework), adding agile elements (Poort, 2014). This study addresses the question how to shape the architecture function to effectively achieve compliance with architecture regulations, of solutions realised in an agile environment. To answer this question a multiple-case study was done, studying three different organisations. The findings are translated into seven propositions

PERCEIVED BENEFITS FROM ENTERPRISE ARCHITECTURE

Enterprise Architecture has been developed in order to optimize the alignment between business needs and the (rapidly changing) possibilities of information technology. But do organizations indeed benefit from the application of Enterprise Architecture according to those who are in any way involved in architecture? To answer this question, a model has been developed (the Enterprise Architecture Value Framework) to organize the benefits of Enterprise Architecture. Based on this model, a survey has been conducted among the various types of stakeholders of Enterprise Architecture, such as architects, project managers, developers and business or IT managers. In the survey the respondents were asked to what extent they perceive various benefits of Enterprise Architecture in their organization. The results of this survey (with 287 fully completed responses) are analyzed and presented in this paper. In all categories of the framework benefits are perceived, though to different extent. Very few benefits are perceived in relation to the external orientation of the organization. Few statistically significant correlations were found in relation to the background of the respondents: the overall view on benefits of Enterprise Architecture appeared independent of the role of the respondents, the economic sector and the number of years of experience with architectur
