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

Topic: EA and Organizational Theory and System Development

Authors: Jouko Poutanen and Mirja Pulkkinen

Affiliation: Faculty of Information Technology, University of Jyvaskyla, Finland

Digital Object Identifier: 10.5220/0010455007260734

Proceedings of ICEIS 2021, ISBN: 978-989-758-509-8

Quick Abstract

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 combination with EAM is scarce in earlier research. To be able to provide guiding ideas for the further development of a dual capability EAM approach, with an evident need, we develop a systems theoretical starting point to examine the cases. Complex Adaptive System (CAS) characteristics appear to give the necessary explanations to build on. Supported by this theoretical development, the study results in principles of a dual capability EAM, for agile strategic business capability building involving enterprise re-structuring.

Detection of Fake Profiles in Social Media - Literature Review

Topics: Web Security and Privacy; Collective Intelligence; Computational Intelligence on the Web; Big Data Technologies and Applications; Data Web Mining

Authors: Aleksei Romanov , Alexander Semenov , Oleksiy Mazhelis and Jari Veijalainen

Affiliation: University of Jyväskylä, Finland

Digital Object Identifier: 10.5220/0006362103630369

Proceedings of WEBIST 2017, ISBN: 978-989-758-246-2

Quick Abstract

False identities play an important role in advanced persisted threats and are also involved in other malicious activities. The present article focuses on the literature review of the state-of-the-art research aimed at detecting fake profiles in social media. The approaches to detecting fake social media accounts can be classified into the approaches aimed on analysing individual accounts, and the approaches capturing the coordinated activities spanning a large group of accounts. The article sheds light on the role of fake identities in advanced persistent threats and covers the mentioned approaches of detecting fake social media accounts.

Quick Abstract

Decisions regarding information system evolution strategy become topical as the organization’s information systems age and start to approach the end of their life cycle. An interview study was conducted in order to compare factors influencing modernization and replacement initiation. System age, obsolete technology and high operation or maintenance costs were identified as triggers for both modernization and replacement projects. The results show that the most prevalent individual reason for modernization initiative is business development. Common initiation factors for replacement projects were end of vendor support and system’s inability to respond to organization’s business needs.

SUPPORT FOR KNOWLEDGE AND INNOVATIONS IN SOFTWARE DEVELOPMENT - Community within Company: Inner Source Environment

Topics: Social and Legal Issues; Communities of Interest; Communities of Practice; Social Networks and Organizational Culture; Social Information Systems; Knowledge Management

Authors: Mirja Pulkkinen ¹ , Oleksiy Mazhelis ¹ , Pentti Marttiin ² and Jouni Meriluoto ²

Affiliations: ¹ University of Jyväskylä, Information Technology Research Institute, Finland , ² Nokia Corporation, United States

Digital Object Identifier: 10.5220/0001280501410150

Proceedings of WEBIST 2007, ISBN: 978-972-8865-79-5

Quick Abstract

This case study considers a software development support portal adapted from open source developer communities into a company internal, so called inner-source development environment. With theoretical insights into knowledge management (KM) models, recent advancements in KM theory building, and observations of the inner source platform we make observations as regarding the KM approach and suggestions for its further development. Both technological and human components of KM are considered. The results of this study, can be generally applicable to the knowledge creation and innovation support in software development. We believe that many software companies are following the example and building virtual environments to support the knowledge processes and innovation in their activities. The case company, Nokia, is a pioneer in KM efforts for the software organization.

The Place and Role of Security Patterns in Software Development Process

Authors: Oleksiy Mazhelis and Anton Naumenko

Affiliation: University of Jyväskylä, Information Technology Research Institute, Finland

Digital Object Identifier: 10.5220/0002478700910100

Proceedings of WOSIS 2006/ICEIS, ISBN: 978-972-8865-52-8

Quick Abstract

Security is one of the key quality attributes for many contemporary software products. Designing, developing, and maintaining such software necessitates the use of a secure-software development process which specifies how achieving this quality goal can be supported throughout the development life-cycle. In addition to satisfying the explicitly-stated functional security requirements, such process is aimed at minimising the number of vulnerabilities in the design and the implementation of the software. The secure software development is a challenging task spanning various stages of the development process. This inherent difficulty may be to some extent alleviated by the use of the so-called security patterns, which encapsulate knowledge about successful solutions to recurring security problems. The paper provides an overview of the state of the art in the secure software development processes and describes the role and place of security patterns in these processes. The current usage of patterns in the secure software development is analysed, taking into account both the role of patterns in the development processes, and the limitations of the security patterns available.

DEPENDABILITY OF LOCATION-BASED SERVICES: A LARGELY OVERLOOKED ASPECT

Topics: B2B and B2C Applications; Wireless and Mobile Computing

Author: Artem Katasonov

Affiliation: Information Technology Research Institute, University of Jyväskylä, Finland

Digital Object Identifier: 10.5220/0002620604890496

Proceedings of ICEIS 2004, ISBN: 972-8865-00-7

Quick Abstract

There is obvious lack of attention to the dependability issues in literature on location-based services (LBS). Both researchers and practitioners were so far too much concerned with the questions about what useful features an LBS should have, while almost completely leaving out the questions about how to assure such basic properties as reliability or response accuracy. However, LBSs are applications that require high dependability, as we argue in this paper, so assuring those is both more critical and more difficult than usually. We discuss the existence of this disagreement between the actual importance of LBS dependability and the level of attention towards it among practitioners and researchers. We also identify and briefly discuss the major factors influencing dependability of LBSs, namely the quality of content, software reliability, algorithms appropriateness, interface quality, and communication quality.

Proceedings of ICEIS 2004, ISBN: 972-8865-00-7

Quick Abstract

The role of modern ICT-services providers has changed from easily defined system engineers to full-scale providers. The types, or profiles, of projects supplied by such providers are not very well understood. In this article a company specific analysis of a set of projects is presented. The analysis clarifies the types of projects and discusses the features of those types. Five distinctive profiles of projects were found excluding the maintenance. Some of the profiles were unexpected and seem to reflect the changing nature of the system engineering market. This change shows that changes to existing methodologies and new methodologies are required in order to offer proper methodological support for modern full-scale ICT-services providers.
