Impacts of electronic process guides by types of user: An experimental study

Abstract

The design and utilization of Electronic Process Guides (EPGs) have been studied in the Software Engineering (SwE) since the1990's. However, the empirical findings from surveys, case studies, and experiments on the beneficial effectffigures of their utilization are still lacking. Thus, we suggest that further research on the utilization of EPGs is required. In this study, we are interested in gaining insights on the effects of using EPGs on objective metrics (learning score, time effort) and subjective metrics (perceived usefulness, ease of use, and value), by comparing three EPG designs (a simple PDF-based EPG, a normal HTML-based EPG, and a sophisticated Java-based EPG) with different blocks of experimental subjects (practitioners, academicians, novices, and experts). To this end we have conducted a controlled experiment with a sample of international participants in the domain of IT Service Management. We found that the utilization of EPGs improves the objective metrics while no improvements were perceived on the subjective ones, and that the sophisticated EPG design is more appropriate for the academic and expert types of users than for the practitioner and novice types. Thus, our main recommendation for the design and utilization of EPGs is to consider the type of enduser,

Insights into Cyber Policies, Information Technology Governance (ITG) and , Multi-stakeholder Security Governance Scaling (MSGS) for Decision Makers within UK SME Aviation

“…CoBIT is helpful as a guide to operational supervisors executing an IT anticipation. Mainly as an apparatus for evaluating the arrangement of business alignment and IT targets (Mora et al, 2016; see also Sallé, 2004 andTan et al, 2009). The emergence of digital transformation, DevOps, as well as the current business trend, underpinned by the common security issues, justify the continue evolution COBIT, to implement a re-alignment.…”

“…Second, the ISO/IEC 29110 design international group has not published also specific guidelines for SCRUM or XP practitioners. Third, given the natural interest on agile methodologies for VSEs, the target market for the ISO/IEC 29110 standards, emerges a practical strong need of elaborating and testing the usability of Deployment Packages (released as Electronic Process Guides) of enhanced SCRUM or XP methodologies (Mora et a, 2016).…”
