Business Process-Aware Maintenance Task: A Preliminary Empirical Study
No full textIn this paper, the authors investigate the usefulness of the knowledge regarding business processes for clarifying change requirements concerning the software systems supporting them. With this in mind, the correctness and completeness of the change requirement impact have been evaluated with and without the business process knowledge. Results of this preliminary empirical study are encouraging and indicate that business information effectively provides a significant help to software maintainers. © 2009 IEEE
Quality evaluation of floss projects: Application to ERP systems
No full textThe selection and adoption of open source software can significantly influence the competitiveness of organisations. Open source software solutions offer great opportunities for cost reduction and quality improvement, especially for small and medium enterprises that typically have to address major difficulties due to the limited resources available for selecting and adopting a new software system. Objective: This paper aims to provide support for selecting the open source software that is most suitable to the specific needs of an enterprise from among the options offering equivalent or overlapping functionality. Method: This paper proposes a framework for evaluating the quality and functionality of open source software systems. The name of the framework is EFFORT (Evaluation Framework for Free/Open souRce projecTs). It supports the evaluation of product quality, community trustworthiness and product attractiveness. The framework needs to be customised to the analysis of software systems for a specific context. Results: The paper presents the customisation of EFFORT for evaluating Enterprise Resource Planning (ERP) open source software systems. The customised framework was applied to the evaluation and comparison of five ERP open source software systems. The results obtained permitted both the refinement of the measurement framework and the identification of the ERP open source software system that achieved the highest score for each chosen characteristic. Conclusion: EFFORT is a useful tool for evaluating and selecting an open source software system. It may significantly reduce the amount of negotiation conducted among an enterprise's members and reduce the time and cost required for gathering and interpreting data. The EFFORT framework also considers the users' opinions by introducing relevance markers associated with the metrics and questions in the data aggregation process
Evolving Enterprise Information System in Small and Medium Enterprise: An Opportunistic Approach and a Case Study
No full textEnterprise Resource Planning -- ERP-software system are considered as tool of strategic relevance for managerial and accounting activity. In the last years, these systems have been considered also by Small and Medium Enterprises SME. However, the literature proposes different framework to aid the company to improve and evolve their Informative System, but they are addressed specifically to large companies. In this paper an analysis of the different approaches is proposed with the aim of defining a new framework designed for small and medium enterprise. Finally, the introduced framework has been applied in a real case stud
Evolving Legacy System toward eLegacy System in eBusiness Context
No full textThe enactment of eBusiness processes requires the effective usage of the existing legacy applications in the eBusiness initiatives. Therefore, technical issues are not enough to drive the evolution of the existing legacy applications, but it is necessary to consider also problems concerning the perspectives, strategies, and businesses of the enterprises. In particular, there is a strict relationship between the evolution of the legacy system and the evolution of the eBusiness process.
In order to support this evolution this paper proposes an approach to extract the requirements for a legacy system evolution from the requirements of the eBusiness process evolution.
The proposed approach aims to characterize the software system within the whole environment in which its evolution will be performed. It provides a set of parameters that are useful to address technical, process, and organizational issues
A Literature Review of Business/IT Alignment Strategies
No full textThe alignment issue was addressed in several researches and numerous methods, techniques and tools were proposed. Choosing the most suitable approach to a specific need is a challenging task. This paper describes a characterization framework that can be applied for evaluating different alignment approaches, with the aim of discovering similarity, maturity, capability to measure, model, asses and evolve the alignment level existing among business and technological assets of an enterprise. A literature review was executed by applying the proposed framework to alignment research approach published in the Information & Management Journal and Journal of Strategic Information Systems. The achieved evaluation results are presented
An assessment strategy for identifying legacy system evolution requirements in eBusiness context
No full textThe enactment of eBusiness processes requires the effective usage of the existing legacy applications inthe eBusiness initiatives. Technical issues are not enough to drive the evolution of the existing legacyapplications, but problems concerning the perspectives, strategies, and business of the enterprises haveto be considered. In particular, there is a strict relationship between the evolution of the legacy systems andthe evolution of the eBusiness processes.This paper proposes a strategy to extract the requirements for a legacy system evolution from therequirements of the eBusiness evolution. The proposed strategy aims at characterizing the software systemwithin the whole environment in which its evolution will be performed. It provides a useful set of attributesaddressing technical, process, and organizational issues.Moreover, a set of assessment activities is proposedaffecting the order in which the attributes are assessed
Tracing Links Between Business Processes and Software Systems
No full textThe traceability links existing between a business process and the supporting software systems s is a critical concern for the organizations, as it directly affects their performance. Methodologies and tools are needed for detecting these kinds of relationships and keeping an evidence of the existing connections. This paper proposes an approach for modelling a business processes evidencing the links existing between their activities and the components of the supporting software systems. The approach described in this paper is concerned with the use of information retrieval techniques to software maintenance and, in particular, to the problem of recovering traceability links between the business process models and the components of the supporting software system. An information retrieval approach is introduced based on two processing phases including syntactic and semantic analysis. The application of the approach is explored through a case study
