ERP implementation methodologies and frameworks: a literature review
Enterprise Resource Planning (ERP) implementation is a complex and vibrant process, one that involves a combination of technological and organizational interactions. Often an ERP implementation project is the single largest IT project that an organization has ever launched and requires a mutual fit of system and organization. Also the concept of an ERP implementation supporting business processes across many different departments is not a generic, rigid and uniform concept and depends on variety of factors. As a result, the issues addressing the ERP implementation process have been one of the major concerns in industry. Therefore ERP implementation receives attention from practitioners and scholars and both, business as well as academic literature is abundant and not always very conclusive or coherent. However, research on ERP systems so far has been mainly focused on diffusion, use and impact issues. Less attention has been given to the methods used during the configuration and the implementation of ERP systems, even though they are commonly used in practice, they still remain largely unexplored and undocumented in Information Systems research. So, the academic relevance of this research is the contribution to the existing body of scientific knowledge. An annotated brief literature review is done in order to evaluate the current state of the existing academic literature. The purpose is to present a systematic overview of relevant ERP implementation methodologies and frameworks as a desire for achieving a better taxonomy of ERP implementation methodologies. This paper is useful to researchers who are interested in ERP implementation methodologies and frameworks. Results will serve as an input for a classification of the existing ERP implementation methodologies and frameworks. Also, this paper aims also at the professional ERP community involved in the process of ERP implementation by promoting a better understanding of ERP implementation methodologies and frameworks, its variety and history

A conceptual model for EAI adoption in an e-government environment
The non-integrated nature of Local Government Authority (LGA) Information Systems (IS) is
strongly associated with the inconsistency and duplication of data, reduction in data integrity and
quality, and high operational and maintenance cost. The reason is that legacy IS within the LGAs
are usually tailored to support particular business processes and functions and are as a
consequence usually difficult to integrate. This gives rise to a strong need for an integrated
architecture that facilitates reuse of existing applications and flexibly implementing business
processes across the functional boundaries within the LGAs. This paper examines a potentially
important area of IS integration in the United Kingdom (UK) LGAs through Enterprise
Application Integration (EAI) technology. A review of the literature indicates that EAI has been a
focal technology for several organisations in solving their integration problems. However, is new
in the LGAs; thus research literature around it is limited. Yet the effect of IS integration using
EAI technology remains under explored, as little research has been conducted to comprehend the
LGAs perception of integration that influences their decisions and actions. The author
demonstrates that it is of high importance to investigate this area within LGAs and result in
research that contributes towards successful EAI adoption. Therefore, resulting in the
development of a conceptual model that may be used to assist the government decision-making
process for EAI adoption in an electronic Government (e-Government) environment
Methodology for Designing Decision Support Systems for Visualising and Mitigating Supply Chain Cyber Risk from IoT Technologies
This paper proposes a methodology for designing decision support systems for
visualising and mitigating the Internet of Things cyber risks. Digital
technologies present new cyber risk in the supply chain which are often not
visible to companies participating in the supply chains. This study
investigates how the Internet of Things cyber risks can be visualised and
mitigated in the process of designing business and supply chain strategies. The
emerging DSS methodology present new findings on how digital technologies
affect business and supply chain systems. Through epistemological analysis, the
article derives with a decision support system for visualising supply chain
cyber risk from Internet of Things digital technologies. Such methods do not
exist at present and this represents the first attempt to devise a decision
support system that would enable practitioners to develop a step by step
process for visualising, assessing and mitigating the emerging cyber risk from
IoT technologies on shared infrastructure in legacy supply chain systems
Semantic discovery and reuse of business process patterns
Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
Aligning a Service Provisioning Model of a Service-Oriented System with the ITIL v.3 Life Cycle
Bringing together the ICT and the business layer of a service-oriented system
(SoS) remains a great challenge. Few papers tackle the management of SoS from
the business and organizational point of view. One solution is to use the
well-known ITIL v.3 framework. The latter enables to transform the organization
into a service-oriented organizational which focuses on the value provided to
the service customers. In this paper, we align the steps of the service
provisioning model with the ITIL v.3 processes. The alignment proposed should
help organizations and IT teams to integrate their ICT layer, represented by
the SoS, and their business layer, represented by ITIL v.3. One main advantage
of this combined use of ITIL and a SoS is the full service orientation of the
company.Comment: This document is the technical work of a conference paper submitted

The Knowledge Application and Utilization Framework Applied to Defense COTS: A Research Synthesis for Outsourced Innovation
Purpose -- Militaries of developing nations face increasing budget pressures, high operations tempo, a blitzing pace of technology, and adversaries that often meet or beat government capabilities using commercial off-the-shelf (COTS) technologies. The adoption of COTS products into defense acquisitions has been offered to help meet these challenges by essentially outsourcing new product development and innovation. This research summarizes extant research to develop a framework for managing the innovative and knowledge flows. Design/Methodology/Approach – A literature review of 62 sources was conducted with the objectives of identifying antecedents (barriers and facilitators) and consequences of COTS adoption. Findings – The DoD COTS literature predominantly consists of industry case studies, and there’s a strong need for further academically rigorous study. Extant rigorous research implicates the importance of the role of knowledge management to government innovative thinking that relies heavily on commercial suppliers. Research Limitations/Implications – Extant academically rigorous studies tend to depend on measures derived from work in information systems research, relying on user satisfaction as the outcome. Our findings indicate that user satisfaction has no relationship to COTS success; technically complex governmental purchases may be too distant from users or may have socio-economic goals that supersede user satisfaction. The knowledge acquisition and utilization framework worked well to explain the innovative process in COTS. Practical Implications – Where past research in the commercial context found technological knowledge to outweigh market knowledge in terms of importance, our research found the opposite. Managers either in government or marketing to government should be aware of the importance of market knowledge for defense COTS innovation, especially for commercial companies that work as system integrators. Originality/Value – From the literature emerged a framework of COTS product usage and a scale to measure COTS product appropriateness that should help to guide COTS product adoption decisions and to help manage COTS product implementations ex post
Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach
Unified Modelling Language (UML) is the most popular modelling language use for
software design in software development industries with a class diagram being the
most frequently use diagram. Despite the popularity of UML, it is being affected by
inconsistency problems of its diagrams at the same or different abstraction levels.
Inconsistency in UML is mostly caused by existence of various views on the same
system and sometimes leads to potentially conflicting system specifications. In
general, syntactic consistency can be automatically checked and therefore is
supported by current UML Computer-aided Software Engineering (CASE) tools.
Semantic consistency problems, unlike syntactic consistency problems, there exists
no specific method for specifying semantic consistency rules and constraints.
Therefore, this research has specified twenty-four abstraction rules of class‟s relation
semantic among any three related classes of a refined class diagram to semantically
equivalent relations of two of the classes using a logical approach. This research has
also formalized three vertical semantic consistency rules of a class diagram
refinement identified by previous researchers using a logical approach and a set of
formalized abstraction rules. The results were successfully evaluated using hotel
management system and passenger list system case studies and were found to be
reliable and efficient
