Enterprise Architecture : A Perspective on How Far We Have Come, and Directions for the Future

Enterprise Architecture (EA) appears to retain the attention of both practitioners and researchers, as the technological complexity of organizations grows. Several researchers have noted that research on EA has been diversifying over time, leading to inconsistent use of terminologies. Further, the benefit claims and other results, rather frequently, are not based on empirical evidence. These shortfalls in research on EA impede EA from maturing as a discipline and from demonstrating its benefit claims. Although there are reasons to believe that the research on EA has progressed, the extent of the progress and the directions for future research are not evident. This study draws on a meta-revi…

Overview of Telecom Operator Software Market

Telecommunications is an essential enabler of modern societies and a global vertical industry, providing communication and information services, with its annual revenue of over trillion euros. In this book, a company providing these services is referred to as a telecom operator or communications service provider (CSP). CSPs create value by offering connectivity to and via an infrastructure of networks for transferring signals. The core business processes in a telecom operator company therefore revolve, on one hand, around physical networks and their maintenance, and on the other, managing their customers and their use of the connectivity services over the networks.

Systemic Management of Architectural Decisions in Enterprise Architecture Planning. Four Dimensions and Three Abstraction Levels

This paper presents a process model for the management of architectural decisions in enterprise architecture planning. First, decisions are made at the enterprise level, with strategic business considerations on the enterprise information, systems and technology strategy and governance issues. The next step is to define the domains, to then go on with domain architecture decisions. At the systems level, the enterprise and domain architecture decisions are collected and converted into architecture descriptions accurate in precision, form and detail to be given as input to the information systems development process, following the architectural planning. The model is derived from previous wor…

Defining Complexity Factors for the Architecture Evaluation Framework

The design and implementation of telecommunication systems is an incremental and iterative process, and system architectures may need to be revised and refined several times during their lifetime. Formal evaluation facilitates the identification of the weak points, where improvements are due in these architectures. In the domain of telecommunications, such evaluation can be based on the Architecture Evaluation Framework (AEF). During the evaluation, a deep understanding of the processes within a system is needed. Meanwhile, the systems being designed are usually complex systems encompassing a large number of components with an intricate pattern of interaction between them. As a result, it i…

Software Business in the Telecommunications Sector

Operations and Business Support Systems (OSS/BSS) software of Communication Service Providers (CSP's) can be developed internally within the CSP or acquired from a Software Vendor. The software industry lifecycle model hypothesizes that software development is internal in the beginning of the industry's lifecycle, and that the share of external products increases when it matures. Empirical evidence shows signs of the OSS/BSS software industry approaching maturity. Current and future developments of the industry include the possibilities of utilizing the Software-as-a-Service (SaaS) model and Open Source software (OSSw). Both have gained increasing interest by the CSP's. However, the relativ…

Towards a Contingency Framework for Engineering an Enterprise Architecture Planning Method

Enterprise architecture (EA) has a key role in managing and relating business strategies and processes, information systems, and IC technologies. EA planning devises an EA plan with development steps to make necessary enhancements to the current state of the affairs in EA. Accomplishing EA planning in a systematic and efficient manner requires the availability of frameworks and methods suitable to the situation at hand. The selection and adaptation of these methodical artifacts for the use of EA planning is often quite challenging in practice. We argue that the contingency approach can help in these activities of method engineering (ME), and present a contingency framework (named here EACon…

Creating the Socio-technical Context Needed to Derive Benefits from Big Data Initiatives in Healthcare

The application of big data in healthcare typifies a complex socio-technical sys- tem. However, although research and practice have advanced the technical aspects of big data, comparable advancements in the social aspects (i.e., human and structural aspects) are lagging. Literature, especially on socio-technical theory, suggests that organizations may only derive benefits from big data initiatives when technical initiatives are adequate- ly complemented by social interventions. Thus, seeing that big data is receiving consider- able attention in healthcare, researchers have called for further research into the social aspects of the application of big data in healthcare. Adopting a socio-tech…

The Essential Competencies of Software Professionals : A Unified Competence Gate Framework

Context Developing high-quality software requires skilled software professionals equipped with a set of basic and essential software engineering competencies (SEC). These competencies and the satisfaction levels derived from them change over a project's lifecycle, or as software professionals move from one project to another. Objective Previous studies suggest a lack of means enabling SEC stakeholders to identify and assess competencies suitable for different projects. Additionally, previous research has mainly portrayed SEC to be static and overlooked their evolution over time and across projects. We investigate how we could effectively identify and match the competencies of software profe…

Organizational processes in ICT Management and Evaluation. Experiences with large organizations.

In this study, we describe the managerial and administrative processes relevant in the assessment of cost, efficiency and value of ICT support within and around an end user organisation. Systems of interdependent processes have been proposed to guide the management of ICT, without looking at the organizational activities, outcomes and interdependencies closer. The changed role of ICT in organizations’ activities does no more allow for isolated management of business and ICT domains. Despite of a lot of talk about business alignment of ICT, a permanent link between the mandates of business and IT management remains yet to be established, even in organisations well aware of their information …

A Practical Approach to EA Planning and Development: the EA Management Grid

Enterprise Architecture is gaining interest as a managerial tool for managing corporate ICT assets and their interplay. Our prior studies indicate that an ICT provider’s viewpoint on EA consulting, planning and development seems to be lacking in the proposed methodologies. Considering both literature and practical EA cases, we suggest an approach that supports restricted assignments in EA management. We present an EA Grid for the management of EA descriptions, requirements, constraints, as well as project tasks and deliverables, task preliminaries and dependencies in EA consulting and development. peerReviewed

Collaborative EA Information Elicitation Method : The IEM for Business Architecture

This study contributes to the enterprise architecture (EA) methodologies by suggesting a method for eliciting architecture requirements: gathering both the current architecture information, and the development needs and requirements for the business architecture (BA) dimension in EA planning. Most of all EA dimensions, the developing of the BA requires collaboration with various non-IT stakeholders. It presents thus challenges to the IT department, or the consultancy involved in EA related efforts. The contribution of the various stakeholder groups as informants is, however, crucial to well founded EA design decisions. The suggested method takes related IS development fields as starting poi…

Key Issues in Enterprise Architecture Adoption in the Public Sector

This paper examines the challenges of enterprise architecture (EA) adoption in public sector organisations. So far, demonstrating the benefits of EA has appeared difficult in this context, and the results in transforming public sector remain modest: Both the penetration and the maturity of EA appear rather low. In the academia, however, the adoption of EA has gained less interest than the EA development and methodologies. Hence, there is a need for research on what are the challenges of EA adoption, and how to overcome them. This paper presents the results of an expert survey on the challenges of EA adoption in the Finnish public sector. The analysis of quantitative data, supported with a q…

A root cause analysis method for preventing erratic behavior in software development: PEBA

Measures taken to prevent faults from being introduced or going undetected can secure development of highly reliable software systems. One such measure is analyzing root causes of recurring faults and preventing them from appearing again. Previous methods developed for this purpose have been reactive in nature and relied heavily on fault reporting mechanisms of ogranizations. Additionally, previous efforts lack a defined mechanism for innovating corrective actions. In this study, we strive to complement the existing methods by introducing a proactive and qualitative method that does not rely on fault data. During the course of the research, in addition to an extensive literature search, an …

Dual Capability EAM for Agility in Business Capability Building : A Systems Theoretical View

Through two cases of IT-enabled business capability building in large enterprises, this paper elucidates how the systems theory approach can explain the enterprise architecture management (EAM) challenge to support business agility. The observation in both of these cases is that a legacy EAM approach does not adapt to a business development scenario involving agility. This leads to a study of the nature of the challenges in EAM when enabling strategic business moves involving new technologies, at the business unit level. For the type of projects as in these cases, we do not find a fitting paradigm in the EAM literature. Suggested solutions are IT bimodality, or Two Speed IT. However, its co…

Software and Standards in an Emerging Domain

This paper considers the software market in the field of e-Learning and Technology Enhanced Learning (TEL) through observing standardization developments in the domain. A model of software market evolution suggests that observations on development and deployment of standards in the domain indicate the status on the market. As the model holds, in a mature phase, level of standardization is high and the number of competing standards low. The result of the study is, there appears to be a market, but a heterogeneous one, with hesitation on dominant designs and an overall modest level of standards adoption. Content standardization enables the (re)use of the learning content in multiple formats w…
