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

Infrastructure-as-a-Service Usage Determinants in Enterprises

The thesis focuses on the research question, what the determinants of Infrastructure-as-a-Service usage of enterprises are. A wide range of IaaS determinants is collected for an IaaS adoption model of enterprises, which is evaluated in a Web survey. As the economical determinants are especially important, they are separately investigated using a cost-optimizing decision support model. This decision support model is then applied to a potential IaaS use case of a large automobile manufacturer

Decision Support Tools for Cloud Migration in the Enterprise

This paper describes two tools that aim to support decision making during the migration of IT systems to the cloud. The first is a modeling tool that produces cost estimates of using public IaaS clouds. The tool enables IT architects to model their applications, data and infrastructure requirements in addition to their computational resource usage patterns. The tool can be used to compare the cost of different cloud providers, deployment options and usage scenarios. The second tool is a spreadsheet that outlines the benefits and risks of using IaaS clouds from an enterprise perspective; this tool provides a starting point for risk assessment. Two case studies were used to evaluate the tools. The tools were useful as they informed decision makers about the costs, benefits and risks of using the cloud.Comment: To appear in IEEE CLOUD 201

Cloud Computing Adoption: A Literature Review on What Is New and What We Still Need to Address

Research on cloud computing (CC) recently emerged congruently with the technology’s importance for organizations at a fast pace. This makes it difficult for practitioners to obtain a consolidated overview of what determines CC adoption based on the numerous papers in this regard. Moreover, for further research in the field to add value, it is necessary to identify what still needs to be addressed. In this vein, we conducted a descriptive review of 39 papers, integrating the results of a previous review on 23 papers from 2014, to compare findings across studies. We identify 44 determinant factors that exhibit consistent directional influence on the dependent meta-variable “CC adoption”, extending previous literature reviews with regard to asset, client, and environmental characteristics. We then critically reviewed the research landscape to identify what is there, and what is not yet covered: Future research should specifically regard the adoption of Infrastructure-, Platform-, and Everything-as-a-Service, private, hybrid, and multi-cloud deployment, investigate vendor, solution, and individual characteristics, analyzing information systems, or the decision-maker

E-finance-lab at the House of Finance : about us

The financial services industry is believed to be on the verge of a dramatic [r]evolution. A substantial redesign of its value chains aimed at reducing costs, providing more efficient and flexible services and enabling new products and revenue streams is imminent. But there seems to be no clear migration path nor goal which can cast light on the question where the finance industry and its various players will be and should be in a decade from now. The mission of the E-Finance Lab is the development and application of research methodologies in the financial industry that promote and assess how business strategies and structures are shared and supported by strategies and structures of information systems. Important challenges include the design of smart production infrastructures, the development and evaluation of advantageous sourcing strategies and smart selling concepts to enable new revenue streams for financial service providers in the future. Overall, our goal is to contribute methods and views to the realignment of the E-Finance value chain. ..

CHALLENGES FOR ADOPTING CLOUD-BASED SOFTWARE AS A SERVICE (SAAS) IN THE PUBLIC SECTOR

Technological advances such as the creation of bandwidth, modular applications and cloud computing have enabled the creation of a distributed collaborative sourcing model named Software as a Service (SaaS). SaaS presents the embodiment of a new service delivery model in which a service provider is delivering its electronic services over the web to many users on a pay per use or period basis. SaaS is still unexplored in the public sector context and its use has been limited. Based on interviews and a group session the main challenges for adopting SaaS are explored from the government perspective. It was found that SaaS could provide many benefits which are related to the outsourcing of the local control, installation and development of software which could result in potential cost-savings and better cost control. Disadvantages and risks are related to the more difficult control of the IT function. Several items were mentioned as both a benefit and disadvantage, as this will be dependent on the organizational arrangements. There are also many challenges that need to be addressed including ensuring the quality, privacy, security and business continuity which require the implementation of organizational changes and governance mechanisms for public sector organizations that are considering SaaS

Assimilation of the Cloud: Challenges to Acceptance, Routinisation and Infusion of Cloud Computing

This study goes beyond a binary view of adoption and instead examines the more complex nature of cloud computing assimilation. It examines (i) acceptance, the extent to which an organisation’s members are committed to the adoption, (ii) routinisation, the extent to which the use of cloud becomes a normal activity, and (iii) infusion, the extent to which more features of the cloud are used than originally planned, the extent to which use is sophisticated, and the extent to which use is emergent. Drawing on 3 case studies, this study will contribute to the existing cloud technologies literature that does not address the complex and multi-faceted nature of adoption. Secondly, it will provide an insight into cloud computing adoption by focusing on the benefits and challenges associated with implementation in organisations. Thirdly, we also seek to develop a set of recommended practices for overcoming such barriers to adoption

Cloud adoption and cyber security in public organizations: an empirical investigation on Norwegian municipalities

The public sector in Norway, particularly municipalities, is currently transforming through the adoption of cloud solutions. This multiple case study investigates cloud adoption and is security challenges that come along with it. The objective is to identify the security challenges that cloud solutions present and techniques or strategies that can be used to mitigate these security challenges. The Systematic Literature Review (SLR) provided valuable insights into the prevalent challenges and associated mitigation techniques in cloud adoption. The thesis also uses a qualitative approach using Semi-Structured Interviews (SSI) to gather insight into informants’ experiences regarding cloud adoption and its security challenges. The study’s empirical data is based on interviews with six different Norwegian municipalities, providing a unique and broad perspective. The analysis of the empirical findings, combined with the literature, reveals several security challenges and mitigation techniques in adopting cloud solutions. The security challenges encompass organizational, environmental, legal, and technical aspects of cloud adoption in the municipality. Based on the findings, it is recommended that Norwegian municipalities act on these issues to ensure a more secure transition to cloud solutions

New Organizational Challenges in a Digital World: Securing Cloud Computing Usage and Reacting to Asset-Sharing Platform Disruptions

Information technology (IT) and IT-enabled business models are transforming the business ecosystem and posing new challenges for existing companies. This two-essay dissertation examines two such challenges: cloud security and the disruption of asset-sharing business models.The first essay examines how an organizations usage of cloud storage affects its likelihood of accidental breaches. The quasi-experiment in the U.S. healthcare sector reveals that organizations with higher levels of digitalization (i.e., Electronic Health Records levels) or those with more IT applications running on their internal data center are less likely to experience accidental breaches after using public cloud storage. We argue that digitalization and operational control over IT applications increase organizations awareness and capabilities of establishing a company-wide security culture, thereby reducing negligence related to physical devices and unintended disclosure after adopting cloud storage. The usage of cloud storage is more likely to cause accidental breaches for organizations contracting to more reputable or domain expert vendors. We explain this result as the consequence of less attention being focused on securing personally accessible data and physical devices given high reliance on reputed and knowledgeable cloud providers. This research is among the first to empirically examine the actual security impacts of organizations cloud storage usage and offers practical insights for cloud security management.The second essay examines how Asset-Sharing Business Model Prevalence (ASBMP) affects the performance implications of industry incumbent firms competitive actions when faced with entrants with asset-sharing business models, like Airbnb. ASBMP represents the amount of third-party products and services that originally were unavailable inside the traditional business model but now are orchestrated by asset-sharing companies in an industry. We use texting mining and econometrics approaches to analyze a longitudinal dataset in the accommodation industry. Our results demonstrate that incumbents competitive action repertoires (i.e., action volume, complexity, and heterogeneity) increase their performance when the ASBMP is high but decrease incumbents performance when the ASBMP is low. Practically, incumbents who are facing greater threat from asset-sharing firms can implement more aggressive competitive action repertoires and strategically focus on new product and M&A strategies. This research contributes to the literature of both competitive dynamics and asset-sharing business models
