The rapid advancement of digital technologies has fundamentally changed the competitive dynamics of the logistics service industry and forced incumbent logistics service providers (LSPs) to digitalize. As many LSPs still struggle in advancing their digital transformation (DT), the purpose of this study is to discover barriers and identify organizational elements and associated leading practices for DT success at LSPs.,This study utilizes a two-stage approach. Stage 1 is devoted to a literature review. Stage 2, based on multiple case studies, analyzes information collected across nine international and global LSPs.,This research derives a practice-based definition of DT in the logistics service industry, and it has identified five barriers, eight success factors and associated leading practices for DT. The main obstacles LSPs struggle with, are the complexity of the logistics network and lack of resources, while the main success factor is a leader having and executing a DT vision, and creating a supportive organizational culture.,The results contribute to the emerging field of DT within the logistics and supply chain management literature and provide insights for practitioners regarding how to effectively implement it in a complex industry.,The authors analyze DT from the perspective of LSPs, traditionally not viewed as innovative companies. This study compares their DT with that of other companies.

Digital transformation at logistics service providers: barriers, success factors and leading practices

ContextEnterprise Architecture (EA) is a strategy to align business and Information Technology (IT) within an enterprise. EA is managed, developed, and maintained throughout the EA Implementation Methodology (EAIM). ObjectiveThe aims of this study are to identify the existing effective practices that are used by existing EAIMs, identify the factors that affect the effectiveness of EAIM, identify the current tools that are used by existing EAIMs, and identify the open problems and areas related to EAIM for improvement. MethodA Systematic Literature Review (SLR) was carried out. 669 papers were retrieved by a manual search in 6 databases and 46 primary studies were finally included. ResultFrom these studies 33% were journal articles, 41% were conference papers while 26% were contributions from the studies consisted of book chapters. Consequently, 28 practices, 19 factors, and 15 tools were identified and analysed. ConclusionSeveral rigorous researches have been done in order to provide effective EAIM, however there are still problems in components of EAIM, including: there is lack of tool support for whole part of EA implementation, there are deficiency in addressing the EAIM's practices especially in modeling, management, and maintenance, there is lack of consideration on non-functional requirement in existing EAIM, there is no appropriate consideration on requirement analysis in most existing EAIM. This review provides researchers with some guidelines for future research on this topic. It also provides broad information on EAIM, which could be useful for practitioners.

A systematic literature review on Enterprise Architecture Implementation Methodologies

Past, current and future trends in enterprise architecture—A view beyond the horizon

A number of methodologies for implementing Enterprise Architecture (EA) have been proposed in the literature. Understanding methodologies' strengths and weaknesses play significant role in selecting appropriate methodology for each EA project. This paper reviews five EA implementation methodologies including: EAP, TOGAF, DODAF, Gartner, and FEA and compare them based on designed framework. Comparison framework is designed based on concepts, modeling, and processes criteria. This comparison provides vast information about selected methodologies based on defined criteria.

A Comparison Enterprise Architecture Implementation Methodologies

Enterprise Architecture (EA) optimizes an enterprise's Information Technology investments and translates business strategies into implementable technology solutions to achieve business competitive environment. This paper provides a review of the Critical Success Factors (CSF) which influences successful EA implementation. Various factors from different CSF models for effective EA implementation and comparisons among models are presented. It is informational and useful for Enterprise Architects considering conducting research on EA and practitioners seeking to assess the 'state-of-play'.

A Review of Critical Success Factors of Enterprise Architecture Implementation

There exists a big demand for secure electronic communications while the expertise level of attackers increases rapidly and that causes even bigger demands and needs for an extreme secure connection. An ideal security protocol should always be protecting the security of connections in many aspects, and leaves no trapdoor for the attackers. Nowadays, one of the popular cryptography protocols is hybrid cryptosystem that uses symmetric and public key cryptography to change secret message. In available cryptography protocol attackers are always aware of transmission of sensitive data. Even noninterested attackers can get interested to break the ciphertext out of curiosity and challenge, when suddenly catches some scrambled data over the network. In this paper we discuss about the disadvantages of asymmetric algorithms in cryptography protocol. Furthermore, this paper proposes new cryptography protocol based on DNA steganography to reduce the usage of public cryptography to exchange session key. In this protocol session key between sender and receiver is hidden by DNA data hiding technique. Therefore, the attackers are not aware of transmission of session key through unsecure channel. Finally, the strength point of the DNA steganography is discussed.

Improving Hybrid Cryptosystems with DNA Steganography

Enterprise Architecture (EA) Implementation Methodologies have become an important part of EA projects. Several implementation methodologies have been proposed, as a theoretical and practical approach, to facilitate and support the development of EA within an enterprise. A significant question when facing the starting of EA implementation is deciding which methodology to utilize. In order to answer this question, a framework with several criteria is applied in this paper for the comparative analysis of existing EA implementation methodologies. Five EA implementation methodologies including: EAP, TOGAF, DODAF, Gartner, and FEA are selected in order to compare with proposed framework. The results of the comparison indicate that those methodologies have not reached a sufficient maturity as whole due to lack of consideration on requirement management, maintenance, continuum, and complexities in their process. The framework has also ability for the evaluation of any kind of EA implementation methodologies.
