An Empirical Study on Decision making for Quality Requirements
[Context] Quality requirements are important for product success yet often
handled poorly. The problems with scope decision lead to delayed handling and
an unbalanced scope. [Objective] This study characterizes the scope decision
process to understand influencing factors and properties affecting the scope
decision of quality requirements. [Method] We studied one company's scope
decision process over a period of five years. We analyzed the decisions
artifacts and interviewed experienced engineers involved in the scope decision
process. [Results] Features addressing quality aspects explicitly are a minor
part (4.41%) of all features handled. The phase of the product line seems to
influence the prevalence and acceptance rate of quality features. Lastly,
relying on external stakeholders and upfront analysis seems to lead to long
lead-times and an insufficient quality requirements scope. [Conclusions] There
is a need to make quality mode explicit in the scope decision process. We
propose a scope decision process at a strategic level and a tactical level. The
former to address long-term planning and the latter to cater for a speedy
process. Furthermore, we believe it is key to balance the stakeholder input
with feedback from usage and market in a more direct way than through a long
plan-driven process
Semantic discovery and reuse of business process patterns
Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
BIM and its impact upon project success outcomes from a Facilities Management perspective
The uptake of Building Information Modelling (BIM) has been increasing, but some of its promoted potential benefits have been slow to materialise. In particular, claims that BIM will revolutionise facilities management (FM) creating efficiencies in the whole-life of building operations have yet to be achieved on a wide scale, certainly in comparison to tangible progress made for the prior design and construction phases. To attempt to unravel the factors at play in the adoption of BIM during the operational phase, and in particular, understand if adoption by facilities managers (FMs) is lagging behind other disciplines, this study aims to understand if current BIM processes can ease the challenges in this area faced by facilities management project stakeholders. To do this, success from a facilities management viewpoint is considered and barriers to facilities management success are explored, with focused BIM use proposed as a solution to these barriers. Qualitative research was undertaken, using semi structured interviews to collect data from a non-probability sample of 7 project- and facilities- management practitioners. Key results from this study show that the main barrier to BIM adoption by facilities managers is software interoperability, with reports that facilities management systems are unable to easily import BIM data produced during the design and construction stages. Additionally, facilities managers were not treated as salient stakeholders by Project Managers, further negatively affecting facilities management project success outcomes. A Ôresistance to change was identified as another barrier, as facilities managers were sceptical of the ability of current BIMenabled systems promoted as being FM compatible to be able to replicate their existing Computer Aided Facility Management (CAFM) legacy software and its user required capabilities. The results of this study highlight that more work is needed to ensure that BIM benefits the end user, as there was no reported use of BIM data for dedicated facilities management purposes. Further investigation into the challenges of interoperability could add significant value to this developing research area.The uptake of Building Information Modelling (BIM) has been increasing, but some of its promoted potential benefits have been slow to materialise.

Understanding the factors that derive continuance intention of e-shopping in Saudi Arabia: Age group differences in behaviour
The objective of this study is to clarify the theoretical problem and identify factors that could explain the level of continuance intention of e-shopping in context of Saudi Arabia. The study proposes a revised technology acceptance model that integrates expectation confirmation theory to measure age differences with regard to continuance online shopping intentions in Saudi Arabia.
The sample (n=465) consists of 68.8% women and 31.4% men, 348 younger than 35 years old and 117 older than 35. A structural equation model confirms model fit. The research findings confirm that Perceived usefulness, enjoyment, and subjective norms are determinants of online shopping continuance in Saudi Arabia. The structural weights are mostly equivalent between the young and old groups, but the regression path from subjective norms to perceived usefulness is not invariant, with that relationship being stronger for the younger respondents.
This research moves beyond online shopping intentions and includes factors affecting online shopping continuance. The model explains 65% of the intention to continue shopping online. The research findings suggest that online strategies cannot ignore either the direct and indirect effects on continuance intentions in Saudi Arabia. The model can be generalized across the three main commercial regions of Saudi Arabia
Information systems evaluation: Navigating through the problem domain
Information systems (IS) make it possible to improve organizational efficiency and effectiveness, which can provide
competitive advantage. There is, however, a great deal of difficulty reported in the normative literature when it comes to the
evaluation of investments in IS, with companies often finding themselves unable to assess the full implications of their IS
infrastructure. Although many of the savings resulting from IS are considered suitable for inclusion within traditional
accountancy frameworks, it is the intangible and non-financial benefits, together with indirect project costs that complicate the
justification process. In exploring this phenomenon, the paper reviews the normative literature in the area of IS evaluation, and
then proposes a set of conjectures. These were tested within a case study to analyze the investment justification process of a
manufacturing IS investment. The idiosyncrasies of the case study and problems experienced during its attempts to evaluate,
implement, and realize the holistic implications of the IS investment are presented and critically analyzed. The paper
concludes by identifying lessons learnt and thus, proposes a number of empirical findings for consideration by decisionmakers
during the investment evaluation process
Creating a culture for radical innovation in a small mature business
This article describes an approach in organizational development to develop an innovation culture for radical product development in a small mature engineering company. The research took place in a business based in the United Kingdom that designed and manufactured instrumentation and specialized packing machines. An initial study within the companyâs new product development team identified key aspects that influenced a radical innovation culture. Nine key themes were found to be pertinent, following an iterative process with the development team. These themes were triangulated using the established Organization Culture Assessment Instrument and the Creative Climate Assessment Tool. A third assessment was developed that gauged the development team culture proximity to an ideal position. Seven interventions were developed in conjunction with the company development team, senior managers, the analysis of previous empirical case research and dialogue with UK companies that promote discontinuous innovation. The results of the interventions were evaluated 4âyears after implementation. The culture was re-assessed using the same assessment tools and the changes were identified. The outcomes are described and they indicate the success of the companyâs attempt to embed a sustainable radical innovation culture into the product development area
