Technical Perspective on Using Information Demand Pattern in a Collaborative Recommendation System for Improving E-Mail Communication
Get PDFToday e-mail communication information is widely used in organizations to distribute information. The increasing volume of received e-mails hinders an efficient work. It becomes more and more difficult to identify relevant e-mails inside this enormous volume of information. This work presents a solution in a multi-user environment by improving an established e-mail client extension based on information demand pattern with a recommendation system. The contributions of this work are (1) the concept and implementation of the solution for a single-user environment using information demand pattern, (2) the concept and architecture to use the solution in a multi-user environment (3) a detailed technical description about the proposed solutions
A Bibliometric Analysis and Review on Performance Modeling Literature
Get PDFIn management practice, performance indicators are considered as a prerequisite to make informed decisions in line with the organization’s goals. On the other hand, indicators summarizes compound phenomena in a few digits, which can induce to inadequate decisions, biased by information loss and conflicting values. Model driven approaches in enterprise engineering can be very effective to avoid these pitfalls, or to take it under control. For that reason, “performance modeling” has the numbers to play a primary role in the “model driven enterprise” scenario, together with process, information and other enterprise-related aspects. In this perspective, we propose a systematic review of the literature on performance modeling in order to retrieve, classify, and summarize existing research, identify the core authors and define areas and opportunities for future research
Conceptual Model of User Adaptive Enterprise Application
Get PDFThe user adaptive enterprise application is a software system, which adapts its behavior to an individual user on the basis of nontrivial inferences from information about the user. The objective of this paper is to elaborate a conceptual model of the user adaptive enterprise applications. In order to conceptualize the user adaptive enterprise applications, their main characteristics are analyzed, the meta-model defining the key concepts relevant to these applications is developed, and the user adaptive enterprise application and its components are defined in terms of the meta-model. Modeling of the user adaptive enterprise application incorporates aspects of enterprise modeling, application modeling, and design of adaptive characteristics of the application. The end-user and her expectations are identified as two concepts of major importance not sufficiently explored in the existing research. Understanding these roles improves the adaptation result in the user adaptive applications
The Diversity of Enterprise Modeling – a Taxonomy for Enterprise Modeling Actions
Get PDFBoth researchers and practitioners have recognized the need for developed knowledge about enterprise modeling. Therefore it is necessary to increase the understanding of various actions that are performed during enterprise modeling, their meaning, and their diversity. This paper proposes a taxonomy with a conceptual structure in two dimensions (hierarchy and process) that could be used to increase the knowledge about enterprise modeling actions. The taxonomy introduces a terminology that enables a better understanding of the modeling actions for a clear purpose. One important aspect of the taxonomy is to create visibility and traceability of decisions made during enterprise modeling activities. These modeling decisions have previously been of a more tacit nature and the taxonomy is supposed to make the rationale behind different modeling decisions explicit and understandable
When Analysts turn into Boxers: An Introduction to Pre-Sales Requirements Engineering
Get PDFThe major goal of a pre-sales phase is to provide customers with a compelling offer that exactly fits their needs. For its creation not only sales but also requirements engineering activities take place. The latter are needed to translate the customers’ needs to features, to efforts, and eventually to costs. Although this sounds like business as usual, compared to conventional requirements engineering, there are substantial differences: the pre-sales phase entails challenges (e.g., a limited duration, a steadily moving target or the supplier’s pre-investment) having a tremendous impact on all of these activities. With their conventional approach requirements engineering professionals are doomed to fail. However, an appropriate requirements engineering approach for the pre-sales phase remains to be defined. To address this issue the principal idea is to investigate typical customer engagement types and to conduct a risk analysis revealing the details of the pre-sales phase’s challenges. The results deliver the basis informing the design of a new and capable approach. This article contributes the resulting concept and tools for successful pre-sales requirements engineering. They provide the risk responses and exit criteria to the pre-sales phase’s challenges. The proposed approach even turns analysts into “boxers” when tackling one of the most difficult pre-sales problems: the moving target
Applying Idea Management System (IMS) Approach to Design and Implement a collaborative Environment in Public Service related open Innovation Processes
Get PDFNovel ideas are the key ingredients for innovation processes, and Idea Management System (IMS) plays a prominent role in managing captured ideas from external stakeholders and internal actors within an Open Innovation process. By considering a specific case study, Lecce-Italy, we have designed and implemented a collaborative environment, which provides an ideal platform for government, citizens, etc. to share ideas and co-create the value of innovative public services in Lecce. In this study the application of IMS with six main steps, including: idea generation, idea improvement, idea selection, refinement, idea implementation, and monitoring, shows that this, remarkably, helps service providers to exploit the intellectual capital and initiatives of the regional stakeholders and citizens and assist service providers to stay in line with the needs of society. Moreover, we have developed two support tools to foster collaboration and transparency: sentiment analysis tool and gamification application
Improvements of Decision Support Systems for Public Administrations via a Mechanism of Co-creation of Value
Get PDFThis paper focuses on a possible improvement of knowledge-based decision support systems for human resource management within Public Administrations, using a co-creation of value’s mechanism, according to the Service-Dominant Logic (SDL) paradigm. In particular, it applies ontology-driven data entry procedures to trigger the cooperation between the Public Administration itself and its employees. Advantages in such sense are evident: constraining the data entry process by means of the term definition ontology improves the quality of gathered data, thus reducing potential mismatching problems and allowing a suitable skill gap analysis among real and ideal workers competence profiles. The procedure foresees the following steps: analyzing organograms and job descriptions; modelling Knowledge, Skills and Attitudes (KSA) for job descriptions; transforming KSAs of job descriptions into a standard-based model with integrations of other characteristics; extracting information from Curricula Vitae according to the selected model; comparing profiles and roles played by the employees.The 'a priori' ontology-driven approach adequately supports the operations that involve both the Public Administration and employees, as for the data storage of job descriptions and curricula vitae. The comparison step is useful to understand if employees perform roles that are coherent with their own professional profiles.The proposed approach has been experimented on a small test case and the results show that its objective evaluation represents an improvement for a decision support system for the re-organization of Italian Public Administrations where, unfortunately often, people are engaged in activities that are not so close to their competences
Selected Topics on Requirements Engineering: Editorial Introduction to the Issue 3 of CSIMQ
Get PDFFor this issue we collected five papers that fall into the domain of Requirements Engineering. It is well known that wrong requirements cause a lot of problems. Some projects totally fail because of that, others waste a lot of money because the correction of resulted errors in the implementation is very time consuming and labour intensive. Therefore, new ideas in identifying the correct requirements are very important
Getting Grip on Security Requirements Elicitation by Structuring and Reusing Security Requirements Sources
Get PDFThis paper presents a model for structuring and reusing security requirements sources. The model serves as blueprint for the development of an organization-specific repository, which provides relevant security requirements sources, such as security information and knowledge sources and relevant compliance obligations, in a structured and reusable form. The resulting repository is intended to be used by development teams during the elicitation and analysis of security requirements with the goal to understand the security problem space, incorporate all relevant requirements sources, and to avoid unnecessary effort for identifying, understanding, and correlating applicable security requirements sources on a project-wise basis. We start with an overview and categorization of important security requirements sources, followed by the description of the generic model. To demonstrate the applicability and benefits of the model, the instantiation approach and details of the resulting repository of security requirements sources are presented
Enabling Support of Collaborative Cross-enterprise Business Processes for Legacy ERP Systems
Get PDFIn order to create innovative business products, share knowledge between people and businesses, or increase the control and quality of services, more and more often enterprise business processes involve in collaborations by delegating or providing some pieces of work to other enterprises. Necessity to cooperate in the cross-enterprise setting leads to Collaborative Business Processes (CBPs). The difference between CBPs and Business Processes (BPs) is in the decentralized coordination, flexible backward recovery, participants notification about the state, efficient adaptability to changes, presence of multiple information systems, and individual authorization settings. In the paper we consider a specific case of CBPs where multiple collaborating partners use Enterprise Resource Planning (ERP) system of the same vendor. The vendor can see (e.g., monitor) the changes of data elements, but does not have explicit process awareness in the ERP system to support flow of activities in the cross-enterprise setting. The paper also discusses different settings of cross-enterprise CBP and shows simplified enterprise models behind the vendor possibilities to positively impact collaborative processes. The restrictions of the vendor are implicit information flows in BP, diversity of ERP integrations with third party Information Systems (IS), the lack of mechanisms for monitoring BP instances, backward recovery, user notification about the current state and tasks, and inability to make explicit changes in customers’ ISs
