Risk management in offshore outsourcing of software production using the ICT-supported unified process model: A cross-case study
2008
Successful execution of ICT-supported unified process of offshore outsourcing (ICT-SUPOO) of software development can offer various important benefits. However, ICT-SUPOO of software development is very complex and risky, and often fails. Almost no empirical studies are available on the risk factors that affect the ICT-SUPOO. The objective of this study is to investigate the key risk factors associated with ICT-SUPOO, understand how they create risks, and how the risks can be alleviated. We carry out a multiple case study from both of the vendorpsilas and clientpsilas sites, where professionals with extensive experience in managing offshore outsourcing of software development were interview…
Software Defined Machine-to-Machine Communication for Smart Energy Management in Power Grids
2020
The successful realization of smart energy management relies on ubiquitous and reliable information exchange among millions of sensors and actuators deployed in the field with little or no human intervention. This motivates us to introduce a unified communication framework for smart energy management by exploring the integration of software-defined networking (SDN) with M2M communication. In this chapter, the overall design of the software-defined M2M (SD-M2M) framework is presented, with an emphasis on its technical contributions to cost reduction, fine granularity resource allocation, and end-to-end QoS guarantee. Then, a case study is conducted for a electric vehicle energy management sy…
Behaviour modelling notation for information system design
2009
Problems related to behaviour modelling within the platform independent model (PIM) during the model driven design are discussed in the paper. The emphasis is on design problems for information systems, especially on building a behaviour draft. At first issues in the traditional approach using sequence diagrams are discussed. Then a new approach based on activity diagrams is proposed. An extension of activity diagram notation specifically oriented towards comprehensive and readable behaviour design description is presented.
Integrating usability work into a large inter-organisational agile development project: Tactics developed by usability designers
2015
We examined how usability activities were integrated in a large inter-organisational agile development project.The collaboration between the usability designers and agile team members was affected by the size and nature of the project.Results showed integration was achieved through 5 tactics employed by the usability designers.Three propositions for organising usability activities in agile projects were derived. In this paper we examine the integration of usability activities into a large inter-organisational agile development project. Inter-organisational agile projects possess unique attributes. They involve multiple stakeholders from different organisational contexts and are thus charact…
A Model for Capturing Product Assembly Information
2005
The important issue of mechanical assemblies has been a subject of intense research over the past several years. Most electromechanical products are assemblies of several components, for various technical as well as economic reasons. This paper provides an object-oriented definition of an assembly model called the Open Assembly Model (OAM) and defines an extension to the NIST Core Product Model (NIST-CPM). The assembly model represents the function, form, and behavior of the assembly and defines both a system level conceptual model and associated hierarchical relationships. The model provides a way for tolerance representation and propagation, kinematics representation, and engineering anal…
Exploring individual personality factors as drivers of M‐shopping acceptance
2009
PurposeThe purpose of this paper is to evaluate how personality variables related to technology (innovativeness, compatibility and affinity) can modify the influence of classical technology acceptance model (TAM) variables on behavioural adoption intention of mobile shopping.Design/methodology/approachThe impact of innovativeness, compatibility, affinity, TAM beliefs (ease of use and usefulness) and attitude on mobile shopping adoption is tested through structural equation modelling techniques. The sample consisted of 470 Spanish mobile telephone users selected on the basis of convenience.FindingsData analysis shows that the effect of perceived usefulness and, in a minor degree, perceived e…
Acceptance of Mobile Health Apps for Disease Management Among People With Multiple Sclerosis: Web-Based Survey Study
2018
Background: Mobile health (mHealth) apps might have the potential to promote self-management of people with multiple sclerosis (MS) in everyday life. However, the uptake of MS apps remains poor, and little is known about the facilitators and barriers for their efficient utilization, such as technology acceptance. Objective: The aim of this study was to examine the acceptance of mHealth apps for disease management in the sense of behavioral intentions to use and explore determinants of utilization among people with MS based on the Unified Theory of Acceptance and Use of Technology (UTAUT). Methods: Participants for this Web-based cross-sectional study were recruited throughout Germany with t…
Acceptance towards digital health interventions – Model validation and further development of the Unified Theory of Acceptance and Use of Technology
2021
Internet- and mobile-based interventions (IMI) offer an effective way to complement health care. Acceptance of IMI, a key facilitator of their implementation in routine care, is often low. Based on the Unified Theory of Acceptance and Use of Technology (UTAUT), this study validates and adapts the UTAUT to digital health care. Following a systematic literature search, 10 UTAUT-grounded original studies (N = 1588) assessing patients' and health professionals' acceptance of IMI for different somatic and mental health conditions were included. All included studies assessed Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions and acceptance as well as age, gender,…
Search for relativistic magnetic monopoles with IceCube
2012
We present the first results in the search for relativistic magnetic monopoles with the IceCube detector, a subsurface neutrino telescope located in the South Polar ice cap containing a volume of 1 km$^{3}$. This analysis searches data taken on the partially completed detector during 2007 when roughly 0.2 km$^{3}$ of ice was instrumented. The lack of candidate events leads to an upper limit on the flux of relativistic magnetic monopoles of $\Phi_{\mathrm{90%C.L.}}\sim 3\e{-18}\fluxunits$ for $\beta\geq0.8$. This is a factor of 4 improvement over the previous best experimental flux limits up to a Lorentz boost $\gamma$ below $10^{7}$. This result is then interpreted for a wide range of mass …
Semantics of UML 2.0 Activity Diagram for Business Modeling by Means of Virtual Machine
2005
The paper proposes a more formalized definition of UML 2.0 Activity Diagram semantics. A subset of activity diagram constructs relevant for business process modeling is considered. The semantics definition is based on the original token flow methodology, but a more constructive approach is used. The Activity Diagram Virtual machine is defined by means of a metamodel, with operations defined by a mix of pseudocode and OCL pre- and postconditions. A formal procedure is described which builds the virtual machine for any activity diagram. The relatively complicated original token movement rules in control nodes and edges are combined into paths from an action to action. A new approach is the us…
