Architects' Perceptions on EA Use -- An Empirical Study

Abstract

Enterprise Architecture (EA) is increasingly being utilized by organizations as an approach to manage the complexity of business processes, information systems and technical infrastructure. Although EA is generally regarded as an effective management tool, its full benefits can be realized only when it is incorporated into day-to-day operations of the organization. In the Finnish public sector, the use of EA has recently been mandated by the newly passed Act on Information Management Governance in Public Administration. The aim of the legislation is to achieve more efficient, integrated and costefficient public services. This article describes the results of a survey aimed to identify perceptions on actual EA work among Finnish public sector participants currently undertaking EA initiatives. The results highlight potential issues related to successful EA adoption.

Modelling the Resistance of Enterprise Architecture Adoption - Linking Strategic Level of Enterprise Architecture to Organisational Changes and Change Resistance

“…For instance Lemmetti and Pekkola (2012) argues that current definitions of EA are inconsistent and thus confusing both researchers and practitioners. This is also supported by Hiekkanen et al, (2013); EA is underutilised due to lack of understanding it properly. In general, poor communication have been found to be one of the factors contributing to EA adoption failures (Mezzanotte et al, 2010).…”

Let’s Get in Touch - Decision Making about Enterprise Architecture Using 3D Visualization in Augmented Reality

“…However, research indicates low use of EAs for decision-making in organizations [1,15,22], in particular for visualizing and, hence, understanding complex IT landscapes [8,27,46]. Potential reasons for this include the limited perceived usefulness of EA visualizations, which are often characterized by their complexity [32], lack of focus [8], an inappropriate level of abstraction [27,46], or insufficient tool support [27].…”

“…Potential reasons for this include the limited perceived usefulness of EA visualizations, which are often characterized by their complexity [32], lack of focus [8], an inappropriate level of abstraction [27,46], or insufficient tool support [27]. In sum, this inhibits the effective use of EAs for decision-making [6], so that stakeholders often find the added value of EA visualizations to be rather low [15,32].…”

A Systematic Review of Enterprise Architecture Adoption Models

“…Hence, various definitions of EA are found. EA acts as a management tool between business and IT strategies, whereby facilitating the evolution to higher level capabilities at the organisation level [3,4] and managing changes from current state to future state [5,6]. EA provides governance and a roadmap for business and IT alignment as well as an investment [7].…”
