A Mobile Healthcare System for Sub-saharan Africa
2013
The disparity between healthcare systems in developed countries and underdeveloped countries is huge, particularly due to the fact that the healthcare infrastructure of former is based on a sophisticated technological infrastructure. Efforts are being made worldwide to bridge this disparity and make healthcare services affordable even to the most remote areas of undeveloped countries. Recent growth of mobile networks in underdeveloped countries argues for building mHealth systems and applications on their basis. However, peculiarities of the area introduce difficulties into potential use cases of mobile devices, thus making the copying of mHealth services from developed countries inapplicab…
Population targeted requirements acquisition
2018
ABSTRACTWe use social science theories, design science research methodology, and our experience in five development projects to design principles for selecting or adapting requirements acquisition (RA) techniques for use with populations of customers and users. The information systems (IS) literature has not systematically focused on the adaption of RA techniques to particular populations. We developed a nascent design theory for RA to target specific populations to define functional requirements for new IS. Five reference theories – personal construct theory, theory of disability, diffusion of innovations, social actor theory, and media richness and information synchronicity theory – suppo…
Dimension enrichment with factual data during the design of multidimensional models: application to bird biodiversity
2015
20 pages; International audience; Data warehouses (DW) and OLAP systems are technologies allowing the on-line analysis of huge volume of data according to decision-makers’ needs. Designing DW involves taking into account functional requirements and data sources (mixed design methodology) [1]. But, for complex applications, existing automatic design methodologies seem inefficient. In some cases, decision-makers need querying, as a dimension, data which have been defined as facts by actual automatic mixed approachs. Therefore, in this paper, we offer a new mixed refinement methodology relevant to constellation multidimensional schema. The proposed methodolgy allows to decision-makers to enric…
Ecosystem Architecture Management in the Public Sector : From Problems to Solutions
2019
Based on our research concerning enterprise architecture (EA) in the Finnish public sector, we discuss how EA concept and tool need to be developed to support government business ecosystem and organization design. Our research context indicates, beyond a federal government or a state one, that even a single municipality, like a city concern, can be perceived as an ecosystem of its sectoral domains, subsidiaries and such. We outline a vision of an overall ontology-based, shared EA repository for the-whole-of-government current state descriptions and specify the central design principles and functional requirements for such a system, illustrating some potential use cases of it. Based on inter…
Requirements elicitation methods based on interviews in comparison: A family of experiments
2020
Abstract Context There are several methods to elicit requirements through interviews between an end-user and a team of software developers. The choice of the best method in this context is usually on subjective developers’ preferences instead of objective reasons. There is a lack of empirical evaluations of methods to elicit requirements that help developers to choose the most suitable one. Objective This paper designs and conducts a family of experiments to compare three methods to elicit requirements: Unstructured Interviews, where there is no specific protocol or artifacts; Joint Application Design (JAD), where each member of the development team has a specific role; Paper Prototyping, w…
Allowing End-Users to Actively Participate within the Elicitation of Pervasive System Requirements through Immediate Visualization
2009
Efficient requirements engineering activities are essential in order to develop software systems that properly satisfy end-user needs. End-users lack knowledge about requirements engineering techniques or computation in general, and it is very important that they actively participate in the requirements elicitation process because they are the "owners" of the problem. In this paper, we present a tool-supported requirements elicitation technique that is centered on end-users and that allows them to describe the main characteristics of pervasive systems. In addition, we provide end-users with an immediate natural visualization of the described requirements. Furthermore, we present a requireme…
Mixed Driven Refinement Design of Multidimensional Models based on Agglomerative Hierarchical Clustering
2015
20 pages; International audience; Data warehouses (DW) and OLAP systems are business intelligence technologies allowing the on-line analysis of huge volume of data according to users' needs. The success of DW projects essentially depends on the design phase where functional requirements meet data sources (mixed design methodology) (Phipps and Davis, 2002). However, when dealing with complex applications existing design methodologies seem inefficient since decision-makers define functional requirements that cannot be deduced from data sources (data driven approach) and/or they have not sufficient application domain knowledge (user driven approach) (Sautot et al., 2014b). Therefore, in this p…
