Business on demand and its mobile solution - study with SAP ByDesign

Business On-Demand solutions are widely used by SMEs in the world today. When I started working in SAP, SAP had just launched its first version mobile solutions for Business On-Demand solutions. SAP ByDesign mobile solution is great, but I believe we could do something even better on mobile phones. My job is focusing on mobile application development. Therefore, I have lots of thoughts about how we could make the mobile solutions better serve desktop solutions and how to distinguish the mobile solutions. Finally I decide to have a further research into this area. The purpose of this thesis is trying to find out how to improve the mobile solutions for Business On-Demand, find out its benefit and limits, and distinguish SaaS mobile solutions from desktop ones. In order to conduct this research, I had some online literature search to find out the Business On-Demand market and major players in this area. I compare the materials from public internet with the ones that are used internally in SAP. I had some interviews with SAP solution manager and SAP‟s potential customers. I finally made some pro-posals for mobile SaaS solutions which I believe will make the solutions better present and much helpful to the customers.

Drivers and barriers of mobile travel and tourism service adoption : a study of individual perceptions and business model development in a travel and tourism context

The Travel and Tourism field is undergoing changes due to the rapid development of information technology and digital services. Online travel has profoundly changed the way travel and tourism organizations interact with their customers. Mobile technology such as mobile services for pocket devices (e.g. mobile phones) has the potential to take this development even further. Nevertheless, many issues have been highlighted since the early days of mobile services development (e.g. the lack of relevance, ease of use of many services). However, the wide adoption of smartphones and the mobile Internet in many countries as well as the formation of so-called ecosystems between vendors of mobile technology indicate that many of these issues have been overcome. Also when looking at the numbers of downloaded applications related to travel in application stores like Google Play, it seems obvious that mobile travel and tourism services are adopted and used by many individuals. However, as business is expected to start booming in the mobile era, many issues have a tendency to be overlooked. Travelers are generally on the go and thus services that work effectively in mobile settings (e.g. during a trip) are essential. Hence, the individuals’ perceived drivers and barriers to use mobile travel and tourism services in on-site or during trip settings seem particularly valuable to understand; thus this is one primary aim of the thesis. We are, however, also interested in understanding different types of mobile travel service users. Individuals may indeed be very different in their propensity to adopt and use technology based innovations (services). Research is also switching more from investigating issues of mobile service development to understanding individuals’ usage patterns of mobile services. But designing new mobile services may be a complex matter from a service provider perspective. Hence, our secondary aim is to provide insights into drivers and barriers of mobile travel and tourism service development from a holistic business model perspective. To accomplish the research objectives seven different studies have been conducted over a time period from 2002 – 2013. The studies are founded on and contribute to theories within diffusion of innovations, technology acceptance, value creation, user experience and business model development. Several different research methods are utilized: surveys, field and laboratory experiments and action research. The findings suggest that a successful mobile travel and tourism service is a service which supports one or several mobile motives (needs) of individuals such as spontaneous needs, time-critical arrangements, efficiency ambitions, mobility related needs (location features) and entertainment needs. The service could be customized to support travelers’ style of traveling (e.g. organized travel or independent travel) and should be easy to use, especially easy to take into use (access, install and learn) during a trip, without causing security concerns and/or financial risks for the user. In fact, the findings suggest that the most prominent barrier to the use of mobile travel and tourism services during a trip is an individual’s perceived financial cost (entry costs and usage costs). It should, however, be noted that regulations are put in place in the EU regarding data roaming prices between European countries and national telecom operators are starting to see ‘international data subscriptions’ as a sales advantage (e.g. Finnish Sonera provides a data subscription in the Baltic and Nordic region at the same price as in Finland), which will enhance the adoption of mobile travel and tourism services also in international contexts. In order to speed up the adoption rate travel service providers could consider e.g. more local initiatives of free Wi-Fi networks, development of services that can be used, at least to some extent, in an offline mode (do not require costly network access during a trip) and cooperation with telecom operators (e.g. lower usage costs for travelers who use specific mobile services or travel with specific vendors). Furthermore, based on a developed framework for user experience of mobile trip arrangements, the results show that a well-designed mobile site and/or native application, which preferably supports integration with other mobile services, is a must for true mobile presence. In fact, travel service providers who want to build a relationship with their customers need to consider a downloadable native application, but in order to be found through the mobile channel and make contact with potential new customers, a mobile website should be available. Moreover, we have made a first attempt with cluster analysis to identify user categories of mobile services in a travel and tourism context. The following four categories were identified: info-seekers, checkers, bookers and all-rounders. For example “all-rounders”, represented primarily by individuals who use their pocket device for almost any of the investigated mobile travel services, constituted primarily of 23 to 50 year old males with high travel frequency and great online experience. The results also indicate that travel service providers will increasingly become multi-channel providers. To manage multiple online channels, closely integrated and hybrid online platforms for different devices, supporting all steps in a traveler process should be considered. It could be useful for travel service providers to focus more on developing browser-based mobile services (HTML5-solutions) than native applications that work only with specific operating systems and for specific devices. Based on an action research study and utilizing a holistic business model framework called STOF we found that HTML5 as an emerging platform, at least for now, has some limitations regarding the development of the user experience and monetizing the application. In fact, a native application store (e.g. Google Play) may be a key mediator in the adoption of mobile travel and tourism services both from a traveler and a service provider perspective. Moreover, it must be remembered that many device and mobile operating system developers want service providers to specifically create services for their platforms and see native applications as a strategic advantage to sell more devices of a certain kind. The mobile telecom industry has moved into a battle of ecosystems where device makers, developers of operating systems and service developers are to some extent forced to choose their development platforms.

Letters from the War of Ecosystems – An Analysis of Independent Software Vendors in Mobile Application Marketplaces

The recent emergence of a new generation of mobile application marketplaces has changed the business in the mobile ecosystems. The marketplaces have gathered over a million applications by hundreds of thousands of application developers and publishers. Thus, software ecosystems—consisting of developers, consumers and the orchestrator—have emerged as a part of the mobile ecosystem. This dissertation addresses the new challenges faced by mobile application developers in the new ecosystems through empirical methods. By using the theories of two-sided markets and business ecosystems as the basis, the thesis assesses monetization and value creation in the market as well as the impact of electronic Word-of-Mouth (eWOM) and developer multihoming— i. e. contributing for more than one platform—in the ecosystems. The data for the study was collected with web crawling from the three biggest marketplaces: Apple App Store, Google Play and Windows Phone Store. The dissertation consists of six individual articles. The results of the studies show a gap in monetization among the studied applications, while a majority of applications are produced by small or micro-enterprises. The study finds only weak support for the impact of eWOM on the sales of an application in the studied ecosystem. Finally, the study reveals a clear difference in the multi-homing rates between the top application developers and the rest. This has, as discussed in the thesis, an impact on the future market analyses—it seems that the smart device market can sustain several parallel application marketplaces.

Promising Prospects in Mobile Search: Business As Usual or Techno-Economic Disruptions?

It has taken more than a decade of intense technical and market developments for mobile Internet to take off as a mass phenomenon. And it has arrived with great intensity: an avalanche of mobile content and applications is now overrunning us. Similar to its wired counterpart, wireless Web users will continuously demand access to data and content in an efficient and user-friendly manner.

Analyzing Business Models for Mobile Augmented Reality

Nowadays, a wide offer of mobile augmented reality (mAR) applications is available at the market, and the user base of mobile AR-capable devices -smartphones- is rapidly increasing. Nevertheless, likewise to what happens in other mobile segments, business models to put mAR in value are not clearly defined yet. In this paper, we focus on sketching the big picture of the commercial offer of mAR applications, in order to inspire a posterior analysis of business models that may successfully support the evolution of mAR. We have gathered more than 400 mAR applications from Android Market, and analyzed the offer as a whole, taking into account some technology aspects, pricing schemes and user adoption factors. Results show, for example, that application providers are not expecting to generate revenues per direct download, although they are producing high-quality applications, well rated by the users.

PSiS mobile

Os sistemas de recomendação têm vindo a ser cada vez mais utilizados nos últimos anos. Por isso, é imprescindível que estes sistemas se adaptem à evolução da sociedade incluindo cada vez mais novas funcionalidades, tais como a adaptação do sistema ao contexto da pessoa. Esta adaptação pode ser feita através de, por exemplo, dispositivos móveis, que têm vindo a apresentar uma taxa de crescimento de vendas muito grande. Dada a crescente integração dos sistemas de recomendação com os sistemas móveis, foi elaborado um estudo sobre o estado da arte dos sistemas de auxílio ao turista que utilizam dispositivos móveis, sendo apresentadas as suas vantagens e desvantagens. Estes sistemas móveis de auxílio a turistas foram divididos em dois grupos: os que apresentam apenas a informação sobre pontos de interesse e os sistemas que são capazes de efectuar recomendações, com base no perfil do turista. Um breve estudo sobre os sistemas operativos para dispositivos móveis é apresentado, sendo especialmente focado o sistema operativo Android que foi o escolhido para esta implementação. Como os dispositivos móveis, actualmente, ainda possuem várias limitações, estas foram descritas e apresentadas as boas práticas no desenvolvimento de aplicações para este tipo de sistemas. É também apresentado um estudo que visa descobrir qual é o método mais leve e mais rápido para trocar dados entre a parte servidora e a parte móvel. Com a parte introdutória apresentada, é exposto o projecto desenvolvido nesta tese, o PSiS Mobile. Este sistema é um módulo que faz parte do projecto PSiS e pretende trazer todas as vantagens dos sistemas móveis para o sistema base já implementado. O projecto PSiS foca-se no estabelecimento de planos de visita personalizados com indicação de percursos para turistas com tempo limitado. Apoiando a definição de planos de visitas de acordo com o perfil do turista (interesses, valores pessoais, desejos, restrições, deficiências, etc.) combinando os produtos de turismo mais adequados (locais de interesse, eventos, restaurantes, etc.) em itinerários eficientes. A utilização de dispositivos móveis para acompanhamento da visita permite uma rápida interacção entre o turista e o sistema. Assim, o PSiS poderá recolher informação contextual do utilizador para que o perfil do mesmo seja enriquecido. O sistema apresentado é composto por duas partes: a parte cliente e a parte servidora. Toda a informação, como por exemplo o perfil do turista, histórico de viagens e valores de similaridade entre utilizadores está presente na parte servidora. O processo de recomendação também é efectuado pela aplicação servidora, sendo esta a responsável pela atribuição de uma classificação aos pontos de interesse tendo em conta o perfil do utilizador em causa. A base de dados do PSiS possui toda a informação relativa aos pontos de interesse numa determinada cidade ou região e o portfólio completo do histórico de visitas de cada utilizador. A componente móvel é uma parte muito importante para o sistema, pois interage com o utilizador no terreno. Um dispositivo móvel como o PDA, não só permite a apresentação de informação relevante ao utilizador, como também permite a recolha automática de informação contextual (por exemplo, a localização). Toda esta informação contribui para a definição de um perfil completo e para uma melhor adaptação do sistema às necessidades do utilizador. De forma a nem sempre estar dependente do servidor, a aplicação móvel possui rotinas para a realização de recomendações básicas. Ou seja, a aplicação móvel não realiza a classificação dos pontos de interesse, mas apenas mostra os principais resultados já formados pela parte servidora. Por exemplo, se um utilizador gostar de comida Chinesa, um restaurante Chinês nas imediações irá ter uma boa classificação e, por isso, ser recomendado. A aplicação móvel mostra ao turista o percurso definido para o dia em que o mesmo se encontra, sendo feito o rastreio do trajecto que o mesmo efectua. Assim, o sistema consegue saber se o horário do planeamento está a ser cumprido ou não. Caso não esteja, é invocado um algoritmo de planeamento que irá tentar corrigir o atraso ou o adiantamento perante o horário inicial. Depois de visitar um ponto de interesse, é pedido ao utilizador para fornecer feedback sobre o mesmo. Se desejado também é possível mostrar os pontos de interesse existentes perto do turista (usando as coordenadas GPS obtidas pelo dispositivo móvel) organizados por categorias, raio de distância, etc. Apesar dos dispositivos móveis possuírem várias restrições, pretendeu-se proporcionar ao utilizador uma boa experiência, através de uma aplicação rápida, de fácil utilização e adaptável, incluindo funcionalidades de planeamento, realidade aumentada e integração com a rede social do sistema. Todos estes factores contribuem para a disponibilização de informação detalhada ao turista.

Transfering data from a server to an Android Mobile application: a case study

Nowadays, due to the incredible grow of the mobile devices market, when we want to implement a client-server applications we must consider mobile devices limitations. In this paper we discuss which can be the more reliable and fast way to exchange information between a server and an Android mobile application. This is an important issue because with a responsive application the user experience is more enjoyable. In this paper we present a study that test and evaluate two data transfer protocols, socket and HTTP, and three data serialization formats (XML, JSON and Protocol Buffers) using different environments and mobile devices to realize which is the most practical and fast to use.

Mobile application to provide personalized sightseeing tours

Tourist recommendation systems have been growing over the last years, mainly because of the use of mobile devices to get user context. This work discuss some of the most relevant systems on the field and presents PSiS Mobile, which is a mobile recommendation and planning application designed to support a tourist during his vacations. It provides recommendations about points of interest to visit based on tourist preferences and on user and sight context. Also, it suggests a visit planning which can be dynamically adapted based on current user and sight context. This tool works like a journey dairy since it records the tourist moves and tasks to help him remember how the trip was like. To conclude, some field experiences will be presented.

Educational application of remote experimentation for mobile devices

In this article the authors describe the application development RExMobile and the importance of remote experimentation via mobile devices, especially smartphones simple, beyond the space provided for this application in education. The article deals the creation, software and hardware that provide an interactive and dynamic way to attract more students to use these experiments remote, serving as support to teachers to science teaching from its initial series. The ease and availability of smartphones, even these students of basic education, permits the reach of new users and in different places. Thus, the practice of remote experimentation in mobile devices enables new spaces for access and interaction. Are used for developing software free or low cost, HTML5 and jQuery Mobile framework, that enable the creation of pages compatible with different mobile operating systems such as iOS, Android, Windows Phone, some Symbian, among others. Also are demonstrated patterns layouts that allow greater accessibility.
