Packaged Software Implementation Requirements Engineering by Small Software Enterprises

Small to medium sized business enterprises (SMEs) generally thrive because they have successfully done something unique within a niche market. For this reason, SMEs may seek to protect their competitive advantage by avoiding any standardization encouraged by the use of packaged software (PS). Packaged software implementation at SMEs therefore presents challenges relating to how best to respond to mismatches between the functionality offered by the packaged software and each SME's business needs. An important question relates to which processes small software enterprises - or Small to Medium-Sized Software Development Companies (SMSSDCs) - apply in order to identify and then deal with these mismatches. To explore the processes of packaged software (PS) implementation, an ethnographic study was conducted to gain in-depth insights into the roles played by analysts in two SMSSDCs. The purpose of the study was to understand PS implementation in terms of requirements engineering (or 'PSIRE'). Data collected during the ethnographic study were analyzed using an inductive approach. Based on our analysis of the cases we constructed a theoretical model explaining the requirements engineering process for PS implementation, and named it the PSIRE Parallel Star Model. The Parallel Star Model shows that during PSIRE, more than one RE process can be carried out at the same time. The Parallel Star Model has few constraints, because not only can processes be carried out in parallel, but they do not always have to be followed in a particular order. This paper therefore offers a novel investigation and explanation of RE practices for packaged software implementation, approaching the phenomenon from the viewpoint of the analysts, and offers the first extensive study of packaged software implementation RE (PSIRE) in SMSSDCs

Information technology, contract and knowledge in the networked economy: a biography of packaged software for contract management

In this research I investigate the intersection of information and communication technology (ICT), contract and knowledge in the networked economy as illuminated by the “life” of contract management software (CMS). The failure of CMS to fulfill market expectations provides the motivating question for this study. Based on interview, survey and archival data, I construct a “biography” of CMS from a market perspective informed by the theory of commoditization as well as studies of markets from economic sociology. From the latter, I draw upon the theory of performativity in markets to identify in the failure of CMS a series of breakdowns in performative assumptions and operations normally at work in the making of a packaged software market, ranging from a failure in classification performativity to a detachment of marketized criteria, in the form of analyst ratings, from the underlying software product and vendors. This catalog of breakdown indicates that packaged software production implicates multiple levels of commoditization, including financialized meta-commodities and marketized criteria, in a dynamic I theorize as substitution of performance. I explore the implications of my findings for packaged software and for process commodities more generally, suggesting, inter alia, that process commoditization may revolve around contract and information exchange rather than product definition. I go on to propose an open theorization of contract as a technology of connectedness, in a relationship of potential convergence, complementarity and substitution with ICT, interpenetrating and performative. My contributions are to information systems and organizations research on the topics of packaged software and the relationship of ICT, contract and organizational knowledge; and to economic sociology on the topics of performativity in markets and product qualification in process commoditization

Evaluating the adoption of enterprise application integration in multinational organisations

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A review of normative literature, in the field of Information Systems (IS) integration, indicates that traditional approaches to applications integration have failed to result in flexible and maintainable IT infrastructures. In addressing this issue, a new technology called Enterprise Application Integration (EAI) has emerged and addresses most of integration problems by resulting in the development of reusable and manageable IT infrastructures. Enterprise application integration is a new research area with many research issues needing to be investigated. At this end, EAI adoption has not efficiently studied with organisations and researchers needing to understand and analyse EAI adoption. This work examines the introduction of enterprise application integration in multinational organisations and proposes a novel model for its adoption. The model is based on a comprehensive set of factors that influence the introduction of EAI in organisations. Since there is an absence of theoretical models for EAI adoption, the proposed model adapts factors that influence the adoption of other integration technologies such as Electronic Data Interchange (EDT). Additional factors like an evaluation framework that supports decision making have been considered by the author as factors that influence EAI adoption. In moving from the conceptual to the empirical, the work is based on a qualitative case study approach to examine the concepts of the proposed model for the adoption of EAI. In doing so, two case studies were conducted at multinational organisations and presented and analysed. However, during the empirical research complementary factors also emerged, which resulted in modifications being made to the previously presented conceptual model. In interpreting from empirical data, it appears that ten main factors influence the adoption of EAT namely: (a) benefits; (b) barriers; (c) costs; (d) internal pressures; (e) external pressures; (f) IT infrastructure; (g) IT sophistication; (h) an evaluation framework for the assessment of integration technologies; (i) evaluation framework for the assessment of EAT packages and, (j) support. The proposed model makes novel contribution at two levels. First, at the conceptual level, as it incorporates factors identified separately in previous studies as influencing adoption of other integration technologies. These factors are used for the development of a consistent model for the adoption and evaluation of EAT. Secondly, the concepts of the proposed model can be used for the adoption of inter-organisational information systems. The proposed model can be used as a decision-making tool to support management when taking decisions regarding the adoption of EAI. Additionally, it can be used by researchers to analyse and understand the adoption of application integration.This work is funded by the Brunel University Department of Information Systems and Computing

Open Source ERP In Organization: Research Agenda

Open Source Software (OSS) is a growing phenomenon, changing the way in which Information Systems (IS) are developed, distributed and implemented. The success of OSS in the worldwide market for operating systems, web servers, and other infrastructure software is substantial. However, it is still infrequent in ERP type application domains, which are said to be impossible to design from an OS angle. While a significant number of research investigate aspects of OS, few researches were dedicated to OS ERP. Based on a review of the academic and professional literature, this paper aims to improve our understanding of the current influence of OS ERP in organizations, to provide a new light on a previously developed topic and to challenge the conventional wisdom in our field which stipulates that there are some areas like ERP applications where OS could not be developed

SOA and BPM, a Partnership for Successful Organizations

In order to stay effective and competitive, companies have to be able to adapt themselves to permanent market requirements, to improve constantly their business process, to act as flexible and proactive economic agents. To achieve these goals, the IT systems within the organization have to be standardized and integrated, in order to provide fast and reliable data access to users both inside and outside the company. A proper system architecture for integrating company’s IT assets is a service oriented one. A service-oriented architecture (SOA) is an IT architectural style that allows integration of the company’s business as linked, repeatable tasks called services. A subject closely related to SOA is Business Process Management (BPM), an approach that aims to improve business processes. The paper also presents some aspects of this topic, as well as the relationship between SOA and BPM. They complement each other and help companies improve their business performance.Information Systems, SOA, Web Services, BPM

An Investigation Into the Ingredients Necessary for a Successful Implementation of SAP

This thesis will focus on the impact of Enterprise Resource Planning (ERP) software applications, mainly SAP, and the impact they have on business functions and efficiency. Businesses have been able to take advantage of improvements in computer technology to make improvements to their every-day processes and procedures. One category of software applications they can use are ERP applications. ERP\u27s provide many advantages for companies - faster access to more reliable data with which to make better decisions, and more efficient use of company resources. These advantages can only be achieved though, if the application is produced and used correctly, which is a challenging task. These implementations are complex processes, requiring extensive modification of company procedures, and a major commitment of employees, time and money. Upper management must plan out the project from beginning to end, considering all the options along the way. One way to make this monstrous task more manageable is by breaking down the implementation into phases: strategy, initiation, definition, transition and improvement. If this project is not planned out appropriately, tragic consequences may occur, including, failure of the system, late or missed orders and squandering the company\u27s money and time. The purpose of this study is to investigate how successful the integrated approach and methodology of an ERP, such as SAP, can be within an organization. Specifically, it is hypothesized that each phase of an implementation will have a serious impact on the successful completion of the project. Numerous case studies of previous implementations were analyzed in this study. These case studies were evaluated by the researchers to determine whether the project was a success or failure, and why. There were also interviews conducted with people who had implemented SAP, and also users of the system. These people had the expertise of doing implementations, the knowledge of how the phases effect one another and how to avoid pit-falls along the way. Results of this analysis produced evidence that the hypothesis be accepted and to conclude that, within the scope of this study, without careful planning, the different phases of an implementation can have a serious impact on the overall success of the implementation project

An approach to identify issues affecting ERP implementation in Indian SMEs

Purpose: The purpose of this paper is to present the findings of a study which is based on the results of a comprehensive compilation of literature and subsequent analysis of ERP implementation success issues in context to Indian Small and Medium scale Enterprises (SME’s). This paper attempts to explore the existing literature and highlight those issues on ERP implementation and further to this the researchers applied TOPSIS (Technique for order preference by similarity to ideal solution) method to prioritize issues affecting successful implementation of ERP. Design/methodology/approach: Based on the literature review certain issues leading to successful ERP implementation have been identified and to identify key issues Pareto Analysis (80-20 Rule) have been applied. Further to extraction of key issues a survey based on TOPSIS was carried out in Indian small and medium scale enterprises. Findings: Based on review of literature 25 issues have been identified and further Pareto analysis has been done to extract key issues which is further prioritized by applying Topsis method. Research limitations/implications: Beside those identified issues there may be other issues that need to be explored. There is scope to enhance this study by taking into consideration different type of industries and by extending number of respondents. Practical implications: By identifying key issues for SMEs, managers can better prioritize issues to make implementation process smooth without disruption. ERP vendors can take inputs from this study to change their implementation approach while targeting small scale enterprises. Originality/value: There is no published literature available which followed a similar approach in identification of the critical issues affecting ERP in small and mid-sized companies in India or in any developing economyPeer Reviewe
