On the use of platforms for product–service solutions

The purpose of this thesis is to identify and describe factors influencing the use of platforms for product–service solutions. Briefly put, product–service solutions are combinations of products and services integrated and customised to address customers’ overall needs. However, because customisation can be costly and time-consuming, following a platform approach can enable companies to meet customers’ individual needs while taking advantage of economies of scale effects at the same time. Compiling five papers, this thesis proposes factors that are influencing the development and applicability of such a platform approach. Drawing from research on product–service solutions and on platform and modular approaches, the thesis seeks to answer three research questions addressing: (1) arguments in favour of using platforms for product–service solutions, (2) how a platform approach influence key aspects of the solutions development, and (3) how a platform approach influence key aspects of the organisational structure. To answer those questions, the research for the thesis adopted a case-study approach. Following a pre-study on Alpha and Beta—an access solutions provider and a healthcare ICT solutions provider, respectively—the lion’s share of data concerns the firm Gamma, operating in the transportation industry. Within the scope of that company, two solutions development projects—the ECOS and COBO projects—were also studied in-depth.As revealed in the case studies, the use of platforms for product–service solutions is influenced by the objectives of the solution business, the solution itself and the organisational architecture, as well as variation in customers’ needs. Further, the thesis outlines three development-focused efforts undertaken in providing product–service solutions based on a platform approach: (1) developing and utilising standardised assets (i.e. a platform), (2) the customising efforts concerned with the configuration of solutions, and (3) personalising activities referring to adaption of the delivery of solutions. Leveraging usage and technology knowledge as shared assets, the thesis identifies two approaches to developing a platform: establishing the platform first or taking a point of departure within an individual solution. Despite arguments in favour of using a platform approach for product–service solutions, implementing such an approach typically presents obstacles. Challenges are likely to arise in an organisation due to the misalignment of the solution architecture with the organisational architecture. After all, the solution architecture encompasses products and services that are inseparable from the development phase forward. However, if products and services are separated organisationally, then the organisational architecture can direct product and service development into different structures, which can cause major challenges in managing the integration needed to provide a seamless solution

Quantitative analysis of take-off forces in birds

The increasing interest on Unmanned Air Vehicles (UAV’s) and their several utilities blended with the need of easy carrying and also the stealth, lead to the need to create the concept of Micro Air Vehicles (MAV’s) and the Nano Air Vehicles (NAV’s). Due to the current interest and the present lack of knowledge on the insect’s and bird’s flight, this study was intended to interpret the forces involved on the moment of the take-off of a bird, recurring to an experiment involving a fast data acquisition force sensor and high speed camera, in addition known facts from earlier studies. In order to do that a bibliographic revision was done, to know what was already studied and to find what could yet be studied. That way could be formed a link on the factors involved on the propulsion of a bird at the moment of take-off. The main conclusions obtained by this work is that the bird can produce movements that will enhance the total moment when the bird stretches its neck forward and moving head down followed by stretching even more its neck and moving head up impelling himself into the air, resulting in a main role on the mechanical forces (against perch) for the bird first moments momentum. Columba livia can generate about 4 times its weight worth mechanic force (against perch) and above 8 times its weight during the 2nd downstroke.O interesse crescente nos Veículos Aéreos não Tripulados “Unmanned Air Vehicles (UAV’s)” e suas diversas utilidades em conjunto com a necessidade de seu fácil transporte e furtividade, levaram à necessidade de criar o conceito dos Micro Veículos Aéreos “Micro Air Vehicles (MAV’s)” e os Nano Veículos Aéreos “Nano Air Vehicles (NAV’s)”. Este tipo de veículos tem como fonte inspiradora os insetos e aves devido à necessária produção simultânea de sustentação e propulsão. Tal como no voo convencional, também no voo animal podem ser identificadas as fases de levantamento (descolagem) e aterragem como diferenciadas do voo longe de uma superfície de apoio. Este trabalho é dedicado ao estudo da fase de levantamento de voo de uma ave columba livia. Foram realizadas experiências para medir a força inicial produzida pela ave para iniciar o voo e a respetiva trajetória na zona próxima do ponto de apoio inicial. Estas medidas foram efetuadas com um sensor de força dotado de elevada velocidade de aquisição de dados e uma camara de alta velocidade. As principais conclusões obtidas com a realização deste trabalho é o facto de que a ave consegue produzir movimentos, que aumentar o momento total quando a ave estica o pescoço para a frente e movendo a cabeça para baixo seguido por continuação de esticamento do pescoço e movimento da cabeça para cima impelindo-se para o ar, resultando num papel principal relativamente às forças mecânicas (contra o poleiro) para o momento linear actuante nos primeiros momentos. Columba livia consegue gerar cerca de 4 vezes o seu peso em força mecânica e acima de 8 vezes o seu peso durante o 2º downstroke

Dynamics of Innovation in an “Open Source” Collaboration Environment: Lurking, Laboring and Launching FLOSS Projects on SourceForge

A systems analysis perspective is adopted to examine the critical properties of the Free/Libre/Open Source Software (FLOSS) mode of innovation, as reflected on the SourceForge platform (SF.net). This approach re-scales March’s (1991) framework and applies it to characterize the “innovation system” of a “distributed organization” of interacting agents in a virtual collaboration environment. The innovation system of the virtual collaboration environment is an emergent property of two “coupled” processes: one involves interactions among agents searching for information to use in designing novel software products, and the other involves the mobilization of individual capabilities for application in the software development projects. Micro-dynamics of this system are studied empirically by constructing transition probability matrices representing movements of 222,835 SF.net users among 7 different activity states. Estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible to computate the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project-joining and project-launching.innovation systems, collaborative development environments, industrial districts, exploration and exploitation dynamics, open source software, FLOSS, SourceForge, project-joining, project-founding, Markov chain analysis.

Skills and capabilities for a sustainable and circular economy: The changing role of design

Implementing practices for a circular economy transforms the way companies do business, notably in the manufacturing industry. However, a circular economy requires a transformation of both production and consumption systems; the standard approach for creation, fabrication, and commerce of products is challenged. Authors repeatedly call for the development of new proficiencies to attend to system transformations, but these so far have not been described for design and engineering. Given that the design of a product directly influences the way a value chain will be managed, building circular, globally sustainable value chains inevitably signifies a fundamental change in the practice of design. Comprehensive analyses were conducted on case studies from a variety of multinational enterprises that are transforming their product strategies for climate change. Changes in design processes were identified, revealing a growing necessity for industry to employ new proficiencies that support closure of material loops. This paper contributes to existing literature by depicting successful practices being implemented in industry. A variety of new capabilities are key to design for a sustainable future; these range from deeper knowledge of material composition to rich understanding of social behaviour. Resulting from this research, learning goals are proposed to serve as guidance for manufacturing companies seeking to tackle climate change. Conclusions aim to encourage researchers and academics to respond to emerging needs by re-thinking education in design and engineering

Introducing branded communities in sport for building strong brand relations in social media

© 2015 Sport Management Association of Australia and New Zealand. Brand communities have become an important aspect for brand management in social media. However, many brands have failed to establish a successful online brand community. In this study, we introduce branded communities as an alternative concept to brand communities. In contrast to brand communities, a branded community does not revolve around a specific (sport) brand, but around any interest or need. However, a specific brand makes use of the community for marketing purposes by sponsoring or operating the community. We emphasize the suitability of sport as an interest around which branded communities can be built as well as links of branded communities to sport sponsorship. We empirically studied the factors which influence the success of this phenomenon and the effects of operating or sponsoring such a community for a brand by using an online survey (N = 501) of members of a branded online community relating to football. The results demonstrate the relevance of topic interest (i.e., identification and involvement with football) and the quality of the community as determinants of interest in and loyalty towards a branded community. The brand owner benefits from an increase in brand loyalty for those community members who are aware of the brand as the operator of the community, whereby awareness of this sponsorship does not decrease loyalty towards the community. Our research contributes to previous knowledge by proving that branded communities are both an effective means for companies to deploy sponsorship and branding strategies in social media and provide a promising opportunity for sport managers to generate value

Industrialising Software Development in Systems Integration

Compared to other disciplines, software engineering as of today is still dependent on craftsmanship of highly-skilled workers. However, with constantly increasing complexity and efforts, existing software engineering approaches appear more and more inefficient. A paradigm shift towards industrial production methods seems inevitable. Recent advances in academia and practice have lead to the availability of industrial key principles in software development as well. Specialization is represented in software product lines, standardization and systematic reuse are available with component-based development, and automation has become accessible through model-driven engineering. While each of the above is well researched in theory, only few cases of successful implementation in the industry are known. This becomes even more evident in specialized areas of software engineering such as systems integration. Today’s IT systems need to quickly adapt to new business requirements due to mergers and acquisitions and cooperations between enterprises. This certainly leads to integration efforts, i.e. joining different subsystems into a cohesive whole in order to provide new functionality. In such an environment. the application of industrial methods for software development seems even more important. Unfortunately, software development in this field is a highly complex and heterogeneous undertaking, as IT environments differ from customer to customer. In such settings, existing industrialization concepts would never break even due to one-time projects and thus insufficient economies of scale and scope. This present thesis, therefore, describes a novel approach for a more efficient implementation of prior key principles while considering the characteristics of software development for systems integration. After identifying the characteristics of the field and their affects on currently-known industrialization concepts, an organizational model for industrialized systems integration has thus been developed. It takes software product lines and adapts them in a way feasible for a systems integrator active in several business domains. The result is a three-tiered model consolidating recurring activities and reducing the efforts for individual product lines. For the implementation of component-based development, the present thesis assesses current component approaches and applies an integration metamodel to the most suitable one. This ensures a common understanding of systems integration across different product lines and thus alleviates component reuse, even across product line boundaries. The approach is furthermore aligned with the organizational model to depict in which way component-based development may be applied in industrialized systems integration. Automating software development in systems integration with model-driven engineering was found to be insufficient in its current state. The reason herefore lies in insufficient tool chains and a lack of modelling standards. As an alternative, an XML-based configuration of products within a software product line has been developed. It models a product line and its products with the help of a domain-specific language and utilizes stylesheet transformations to generate compliable artefacts. The approach has been tested for its feasibility within an exemplarily implementation following a real-world scenario. As not all aspects of industrialized systems integration could be simulated in a laboratory environment, the concept was furthermore validated during several expert interviews with industry representatives. Here, it was also possible to assess cultural and economic aspects. The thesis concludes with a detailed summary of the contributions to the field and suggests further areas of research in the context of industrialized systems integration
