    Persona is a tool broadly used in technology design to support communicational interactions between designers and users. Different Persona types and methods have evolved mostly in the Global North, and been partially deployed in the Global South every so often in its original User-Centred Design methodology. We postulate persona conceptualizations are expected to differ across cultures. We demonstrate this with an exploratory-case study on user-created persona co-designed with four Namibian ethnic groups: ovaHerero, Ovambo, ovaHimba and Khoisan. We follow a hermeneutic inquiry approach to discern cultural nuances from diverse human conducts. Findings reveal diverse self-representations whereby for each ethnic group results emerge in unalike fashions, viewpoints, recounts and storylines. This paper ultimately argues User-Created Persona as a potentially valid approach for pursuing cross-cultural depictions of personas that communicate cultural features and user experiences paramount to designing acceptable and gratifying technologies in dissimilar locales

    Theorising the design-reality gap in ICTD: matters of care in mobile learning for Kenyan community health workers

    This thesis examines the sociomaterial relations of “design practice” in order to advance new perspectives on success and failure in Information and Communication Technology for Development (ICTD). I conduct an ethnographic case study of an academic research intervention and update the widely-cited theory of design-reality gaps (Heeks, 2002). Using methods from classic actor-network theory and post-structural material-semiotic tools, the analysis: 1) disentangles the entwined sociomaterial practices around design, production, and use of technology; and 2) integrates these insights into more elaborate conceptualisations of gaps, sustainability, scalability, and project failure. In doing so, my study answers the research question: What are the sociomaterial relations of “design practice” in a globally-distributed, multi-stakeholder, and technologicallymediated ICTD project for poverty alleviation? My research narrative describes how an array of humans and non-humans participated as designers in a transnational, interdisciplinary Participatory Action Research project to train Kenyan health workers using mobile phones. At least six different patterns of sociomaterial relations operated through a given set of people and things, enacting the material-discursive apparatuses (Barad, 1998) of educational research, healthcare, the market, the state, and the local community. I assert that in this Participatory Action Research project for mobile learning, the design-reality gap was not so much a matter of geographic or socio-cultural divides, but was instead constituted as fluid space (Mol, 2002) separating the educational researchers’ designerly practices from the multiplicity of ways in which health workers, mobile phones, and other actors lived in relation to one another. I conclude that these ontological politics enacted design as an empirical matter of care – an affective and morally-charged sociomaterial practice with an ethico-political commitment to the marginalised (Puig de la Bellacasa, 2011). I therefore present a conceptual model of success and failure in participatory ICTD projects that explicitly incorporates the affective and material dimensions of care, and conceptualises social justice – not solely in terms of universal claims or global standards – but as embodied, sociomaterial enactments

    A P2P middleware design for digital access nodes in marginalised rural areas

    This thesis addresses software design within the field of Information and Communications Technology for Development (ICTD). Specifically, it makes a case for the design and development of software which is custom-made for the context of marginalised rural areas (MRAs). One of the main aims of any ICTD project is sustainability and such sustainability is particularly difficult in MRAs because of the high costs of projects located there. Most literature on ICTD projects focuses on other factors, such as management, regulations, social and community issues when discussing this issue. Technical matters are often down-played or ignored entirely. This thesis argues that MRAs exhibit unique technical characteristics and that by understanding these characteristics, one can possibly design more cost-effective software. One specific characteristic is described and addressed in this thesis – a characteristic we describe here for the first time and call a network island. Further analysis of the literature generates a picture of a distributed network of access nodes (DANs) within such network islands, which are connected by high speed networks and are able to share resources and stimulate usage of technology by offering a wide range of services. This thesis attempts to design a fitting middleware platform for such a context, which would achieve the following aims: i) allow software developers to create solutions for the context more efficiently (correctly, rapidly); ii) stimulate product managers and business owners to create innovative software products more easily (cost-effectively). A given in the context of this thesis is that the software should use free/libre open source software (FLOSS) – good arguments do also exist for the use of FLOSS. A review of useful FLOSS frameworks is undertaken and several of these are examined in an applied part of the thesis, to see how useful they may be. They form the basis for a walking skeleton implementation of the proposed middleware. The Spring framework is the basis for experiments, along with Spring-Webservices, JMX and PHP 5’s web service capabilities. This thesis builds on three years of work at the Siyakhula Living Lab (SLL), an experimental testbed in a MRA in the Mbashe district of the Eastern Cape of South Africa. Several existing products are deployed at the SLL in the fields of eCommerce, eGovernment and eLearning. Requirements specifications are engineered from a variety of sources, including interviews, mailing lists, the author’s experience as a supervisor at the SLL, and a review of the existing SLL products. Future products are also investigated, as the thesis considers current trends in ICTD. Use cases are also derived and listed. Most of the use cases are concerned with management functions of DANs that can be automated, so that operators of DANs can focus on their core business and not on technology. Using the UML Components methodology, the thesis then proceeds to design a middleware component architecture that is derived from the requirements specification. The process proceeds step-by-step, so that the reader can follow how business rules, operations and interfaces are derived from the use cases. Ultimately, the business rules, interfaces and operations are related to business logic, system interfaces and operations that are situated in specific components. The components in turn are derived from the business information model, that is derived from the business concepts that were initially used to describe the context for the requirements engineering. In this way, a logical method for software design is applied to the problem domain to methodically derive a software design for a middleware solution. The thesis tests the design by considering possible weaknesses in the design. The network aspect is tested by interpolating from formal assumptions about the nature of the context. The data access layer is also identified as a possible bottleneck. We suggest the use of fast indexing methods instead of relational databases to maintain flexibility and efficiency of the data layer. Lessons learned from the exercise are discussed, within the context of the author’s experience in software development teams, as well as in ICTD projects. This synthesis of information leads to warnings about the psychology of middleware development. We note that the ICTD domain is a particularly difficult one with regards to software development as business requirements are not usually clearly formulated and developers do not have the requisite domain knowledge. In conclusion, the core arguments of the thesis are recounted in a bullet form, to lay bare the reasoning behind this work. Novel aspects of the work are also highlighted. They include the description of a network island, and aspects of the DAN middleware requirements engineering and design. Future steps for work based on this thesis are mapped out and open problems relating to this research are touched upon

    Why do aid information management systems fail? Understanding global diffusion of data-driven development initiatives and sustainability failure in the case of Indonesia

    Get PDF
    Aid information management systems (AIMS) have been implemented in aidreceiving countries with the hope that they will enable donors and recipient governments to share aid information, enhance data governance and aid coordination among stakeholders. Despite the global popularity of data-driven development initiatives and heavy investment in AIMS, many systems have not fulfilled the expected outcomes. This research seeks to explain this failure from an information systems perspective. Building on a historical overview of AIMS implementation, I first develop an understanding of how such systems evolved and how the visions of aid effectiveness norms that AIMS inscribed have changed over time alongside the shifting global aid governance. This overview clearly shows that, in many cases, AIMS did not attain the result anticipated, and often failed to reach sustainability. I then investigate this sustainability failure, through an interpretive case study of Indonesian AIMS. I trace the change of international and domestic aid governance that shaped the unique context of AIMS in the emerging economy. Investigating the role of state actor, I argue that understanding the failure of AIMS requires a shift of attention from the process of aid management within a country to the global level. It needs to be seen as a result of macro-level events occurring in the global field of aid. In the dynamics of global power relations, the role of technology is multifaceted—a mixture of managerial and rationalizing, as well as symbolic and political roles

    Peer-to-peer in the workplace: A view from the road

    ABSTRACT This paper contributes to the growing literature on peer-topeer (P2P) applications through an ethnographic study of auto-rickshaw drivers in Bengaluru, India. We describe how the adoption of a P2P application, Ola, which connects passengers to rickshaws, changes drivers work practices. Ola is part of the 'peer services' phenomenon which enable new types of ad-hoc trade in labour, skills and goods. Autorickshaw drivers present an interesting case because prior to Ola few had used Smartphones or the Internet. Furthermore, as financially vulnerable workers in the informal sector, concerns about driver welfare become prominent. Whilst technologies may promise to improve livelihoods, they do not necessarily delive

    Exploring user experience (UX) factors For ICTD services

    Consistent with global entities such as the United Nations- through the World Summit of the Information Society (WSIS), introduction of Information and Communication Technology (ICT) for human development has seen the introduction of ICT-based services aimed at facilitating socio-economic development of marginalized communities. The use of ICTs has always solicited the concept of Human Computer Interaction (HCI), which involves the methods which humans interact with technology. The types of User Interfaces (UIs) and interaction techniques that people use to interact with ICTs affects the way they perceive technology and eventually, their acceptance of the technology. Current ICT systems still haven‟t adopted the concept of placing the user at the core of the interaction. Users are still required to adapt themselves to the interface‟s characteristics; which limits the number of people who can use the system due to inabilities to adapt to the interface. As a result, the information embedded in these technologies is still inaccessible and useless to Marginalized Rural Area (MRA) users. Such usability challenges can be mitigated against and avoided by matching UI components with the users‟ mental models, language, preferences, needs and other socio-cultural artefacts. In this research, literature in Human-Computer Interaction (HCI) is reviewed with emphasis on the usability and User Experience (UX) during user interaction with ICTs using various modes of interactions. HCI emphasizes the need for systems to take account of user‟s characteristics such as their abilities, needs, socio-cultural experiences, behaviours and interests. In efforts to meet the requirement of UX, the user, system and the context of use, need to be evaluated, taking into consideration that changing one entity modifies the UX. This will be achieved by persona profiling to determine the key characteristics of the user communities, clustered according to the key UX attributes. Subsequently, through detailed usability evaluations, including the use of System Usability Scale (SUS) to determine user satisfaction with various UI components/techniques per identified persona- thus providing and persona mapping for usability of Information and Communication Technology for Development (ICTD) services. The results from this research are reflective of the importance of creating personas for usability testing. Some of the personas do not have a problem with interacting with most of the interfaces but their choice of interface comes from a preference point of view. For some personas, their skills and level of experience with ICTs motivates their choice of interface. The common UI component that users from across the spectrum appreciate is UI consistency which makes interaction easier and more natural. Common obstacles with current User Interfaces (UIs) that inhibit users from MRAs include the hefty use of text in interfaces, unintuitive navigation structures and the use of a foreign language. Differences in UIs from different application developers present an inconsistency which challenges the users from rural areas. These differences include the layout, the text entry methods and the form of output produced. A solution to this has been identified from the usability test as the use of speech-enabled interfaces in a language that can be understood by the target audience. In addition, through literature study it has been found that UX of interfaces can be improved by the use of less textual or text-free interfaces. Based on literature, users from MRAs can benefit from using hand-writing based UIs for text-based entry which mimics pen and paper environment for literate users who have experience with writing. Finally, the use of numbered options can assist illiterate users in tasks that requires users to choose options and for navigation. Therefore, consistency in UIs designed to be used by MRA users can improve usability of these interfaces and thus, improving the overall UX
