- This article investigates the evolution of data quality issues from traditional structured data managed in relational databases to Big Data. In particular, the paper examines the nature of the relationship between Data Quality and several research coordinates that are relevant in Big Data, such as the variety of data types, data sources and application domains, focusing on maps, semi-structured texts, linked open data, sensor & sensor networks and official statistics. Consequently a set of structural characteristics is identified and a systematization of the a posteriori correlation between them and quality dimensions is provided. Finally, Big Data quality issues are considered in a conceptual framework suitable to map the evolution of the quality paradigm according to three core coordinates that are significant in the context of the Big Data phenomenon: the data type considered, the source of data, and the application domain. Thus, the framework allows ascertaining the relevant changes in data quality emerging with the Big Data phenomenon, through an integrative and theoretical literature review.

Towards Structured Flexibility in Information Systems Development : Devising a Method for Method Configuration
- 2009

Journal article (peer-reviewed)abstract
- Method configuration is a specific type of Method Engineering (ME) that takes an existing organization-wide Information Systems Development Method (ISDM) as its point of departure. Existing assembly-based ME approaches are not well suited to this task. As an alternative, this article suggests a metamethod approach to tailoring organization-wide ISDMs. We refer to this approach as the Method for Method Configuration (MMC). MMC takes into account the need to combine structure, which is one reason for choosing an organization-wide ISDM in the first place, with flexibility, which is essential for making the chosen ISDM fit actual projects. The metamethod is built using a three-layered reuse model comprising method components, configuration packages, and configuration templates. These concepts are combined efficiently to produce a situational method and thereby to facilitate the work of method engineers.

Design Science Research : The Road Traveled and the Road That Lies Ahead
- 2013
-
In: Journal of Database Management. - : IGI Global. - 1063-8016 .- 1533-8010. ; 24:3, s. 1-8
-
Journal article (peer-reviewed)abstract
- In this introductory piece to the special issue on design science research (DSR) in information systems, the authors probe the past research in DSR, introduce the papers in the special issue, discuss their contributions to the field, and conclude the paper by highlighting some potential directions for future research. To provide a good overview of the research domain, the authors review the key research approaches (or processes) that have been proposed and identify the concrete products of DSR that come in the form of artifacts. As the production of artifact is only part of the DSR process, the authors discuss the role of theorizing about these results and propose avenues for future design-oriented research. It is the authors' strong belief that DSR should be at the heart of information systems discipline because it invites people to research the issues surrounding the development and organizational implementation of new systems.
