Query-Based Multicontexts for Knowledge Base Browsing: An Evaluation

In [7], we introduced the query-based multicontext theory, which allows to define a virtual space of views on ontological data. Each view is then materialised as a formal context. While this formal context can be visualised in a usual formal concept analysis framework such as Conexp or ToscanaJ, [7] also briefly described how the approach allowed the creation of a novel navigation framework for knowledge bases. The principle of this navigation is based on supporting the user in defining pertinent views. The purpose of this article is to discuss the benefits of the browsing interface. This discussion is performed, on the one hand, by comparing the approach to other Formal Concept Analysis based frameworks. On the other hand, it exposes the preliminary evaluation of the visualisation of formal contexts by comparing the display of a lattice to two other approaches based on trees and graphs

Challenges and Success Factors for Metrics in Large-Scale Agile Development

Contemporary organizations widely use agile software development to react to unpredictable changes in their business environment. Due to the success of agile methods in contexts similar to the agile sweet spot, organizations have been applying them on a larger scale. However, maintaining oversight in large-scale agile development remains a problem. Metrics can tackle this problem by increasing transparency, but organizations have struggled with their adoption. Furthermore, extant research on large-scale agile development lacks publications investigating metric challenges and success factors. Against this backdrop, we conducted an expert interview study with 23 experts from 13 organizations. The most mentioned challenges are data collection challenges, lack of metric usefulness, and metric calculation challenges. On the other hand, the most occurring success factors are context-dependent metric adoption, implementing an agile metric management process, and ensuring understanding of the metric purpose
