This research investigates mobile service design and engineering in the mobile telecommunications industry.The mobile telecommunication business is shifting from one that was voice-centric to one that is almost all data-centric; thanks to recent rapid advances in Information and Communication Technologies (ICTs).The underlying reasons behind this shift can be traced back to two main issues that are interlinked.The first and major reason is that telecoms (telecommunication companies) are trying to generate new revenue streams based on data and information transmissions, given the saturation of the voice market.This is rational given the market opportunities in one direction and the pressures being generated by the current economic downturn from the other direction.The second reason relates to the flexibility of data, compared to voice.Indeed, the number of services that can be developed on the basis of data are much greater than those that can be developed on the basis of voice.However, the design and engineering of successful and innovative mobile data services has proven to be a complex undertaking.The number of effective mobile data services is relatively small and the revenue generated from such offerings has generally been below expectations.This research develops an ontological framework to help in changing this situation, and making mobile services engineering more effective and successful, following the design-science research paradigm.Design-science research, in general, aims to solve unstructured but relevant organizational or social problems through the development of novel and useful artefacts.As the current research aims to help in solving the mobile data services engineering dilemma by developing a purposeful ontological framework, the designscience research paradigm is deemed fitting.Within this paradigm, the author develops a novel design approach specified for ontology engineering, termed "OntoEng".This design approach is used in this research for developing the ontological framework.The developed ontological framework is founded on business model thinking.The idea is that creating innovative mobile data services requires developing innovative business models.Indeed, innovative business models can help translate technological III The Design and Engineering of Innovative Mobile Data Services Mutaz M. Al-Debei potential into economic value and allow telecoms to achieve their strategic objectives.The ontological framework includes the development of an ontology, termed "V 4 Mobile Service BM Ontology" as well as "Mobile Key Value Drivers" for designing and engineering innovative mobile data services.The V 4 Mobile Service BM Ontology incorporates four design dimensions: (1) value proposition including targeting; (2) value architecture including technological and organizational infrastructure; (3) value network dealing with aspects relating to partnerships and cooperations; and finally (4) value finance relating to costs, pricing, and revenue structures.Within these four dimensions, sixteen design concepts are identified along with their constituent elements.Relationships and interdependencies amongst the identified design constructs are established and clear semantics are produced.The research then derives six key value drivers for mobile service engineering as follows: (a) Market Alignment; (b) Cohesion; (c) Dynamicity; (d) Uniqueness; (e) Fitting Network-Mode; and (f) Explicitness.The developed ontological framework in this research is evaluated to ensure that it can be successfully implemented and performs correctly in the real world.
