Incorporating electronics and software systems into manufactured goods is becoming very common in manufacturing companies. New technical functions, increased flexibility, and compensation for mechanical design weaknesses are some key drivers of this technological change in our everyday products. The automotive industry exemplifies this trend, since approximately 80–90% of new functions in cars are based on electronics and software, and it is expected that at least a third of the total cost of a car will eventually be accounted for by electronics and software. However, one of the main downsides of this technological trend is the increasing number of quality issues related to these new technologies, something usually claimed to be a result of the increased product development complexity. Previous research into product development management has mainly concentrated on either physical products or software systems, but not concurrently on both. Additionally, much of the research has concentrated on issues of integrating marketing, R&amp;D, and manufacturing in these companies, and has treated the engineering disciplines in R&amp;D as a homogenous group. Motivated by this change in technology content and the lack of research into complex product development and especially into integration between engineering disciplines, the present work investigates how to increase operational performance in multidisciplinary engineering organizations. This work has especially focused on interdisciplinary integration and the feasibility of various so-called integration mechanisms, such as building common physical facilities, job rotation programs, the implementation and use of information and communications technology, and computer-aided engineering tools. Both qualitative and quantitative research has been performed, involving 11 different companies and over 300 respondents. Supported by the present findings, it is demonstrated that interdisciplinary integration is a crucial factor to consider, and it is concluded that certain integration mechanisms stand out as more important than others. Organizational structure, work procedures and methods, training, social systems, and computer-aided engineering were the five types of mechanisms that displayed the greatest potential for improvement. It is further concluded that the ability to successfully match the body of practices to current products is essential, since there is a high risk of current practices becoming out-dated with respect to the technology content. Furthermore, inadequate identification of or managerial ability to establish the currently most important interfaces complicate the choice of trade-offs between various technologies that are found to be essential to cope with the inherent dynamic complexity. The organizational powerbase is often re-positioned in the studied organizations, and the loss of decisive power can result in a demoralizing ignorance of newly established disciplines and their design practices. Additionally, rigid structures and counterproductive traditions can reduce the potential gains accruing from new boundary-spanning innovations, so organizational responsibilities and mandates must be declared unambiguously, in many cases differently from how they have been in the past. Based on these conclusions, it is suggested that managers in organizations like those studied must be able to do the following: cultivate software knowledge in all parts and levels of the product development organization; reassess their recruitment strategies; organize for interdisciplinary collaboration; articulate and communicate the technology fusion strategy to all disciplines; and realize and disseminate the fact that product launches do not only concern manufacturability. / QC 20100621

In any organization, formal and informal face-to-face meetings make up a profound part in the daily life of its members. Meetings are played out continuously, some formal, such as a management board meeting, an information meeting, or a project meeting. The formal meetings people “attend to”, “participate in”, or “are in charge of” depending on a person’s position within them. Other meetings are less formal, such as a desk-side discussion, a chat in the hallway, or a private conversation between two colleagues. The latter often just appear, seemingly by chance. This dissertation examines meetings, as a way of observing the organizing process of complex product development projects. More specifically, organizations engaging in complex product development can be viewed as tension systems, where the dominant tension is between innovation and control. From this perspective, a critical challenge for a product development project becomes one of managing a balancing act between individual action and creativity, on one hand, and collaboration and control, on the other, ensuring that ideas and knowledge retrieved by their parts can be pooled into an integrated whole. By studying the interplay between different types of face-to-face meetings that took place in two projects developing telecommunication systems, this thesis engages in an inquiry of how this balancing act was played out in practice. The findings of the study suggest that the informal meetings comprised occasions that facilitated the perception of complex and ambiguous issues and gave rise to innovative interpretations of how to deal with them. When issues have been defined and interpreted, formal meetings were used to “elevate” and “enter” them into a formal existence. Then, formal claims for action could be established in which people in the projects were organized around the task of solving a specific and recognized problem.  Thus, formal meetings served as a controlling and structuring function. / <p>Diss.

Due to different engineering background and limited technical prerequisites, trade-offs are needed when managing information in complex product development. The challenges faced with information management for complex product development are as much of organizational as technical character. Information management has in this thesis been analyzed from both a technical and organizational dimension in order to obtain an integrated view and holistic understanding. The technical dimension focuses on information management systems, such as product lifecycle management systems. An information management system in itself does not solve problems in an organization; it manages at its best all types of business data while storing and retrieving information. In order to succeed, information management needs to be aligned with different needs and with a variety of domain-specific work procedures. The organizational dimension includes organizational structures, work procedures, and the designer and management perspectives on needs and benefits with information management. Perceived benefits with integrated information management are identified as support for SE, work procedure mapping, use of disciplinary support tools, and data integrity and availability. Five technical and organizational key success factors for efficient information management are presented; usability, integration of information, motivation, information structure and organizational support. It is concluded that structured information, management support and motivation among designers are more important than customization of information management systems in order to achieve integrated information management. / <p>QC 20101112</p>

The purpose of this thesis is to contribute to New Product Development-literature by expanding the analysis of the R&amp;D-manufacturing interface in complex product development in three areas, i.e. the outsourcing of manufacturing, uncertainty and time-criticality, and field service. The thesis focuses on interface challenges and solutions which concern three questions: How does the level of outsourcing of manufacturing affect the management of the R&amp;Dmanufacturing interface in complex product development? How does the presence of uncertainty and time-criticality affect the management of the R&amp;Dmanufacturing interface in complex product development? How does the need to consider field service requirements affect the management of the R&amp;Dmanufacturing interface in complex product development? The background and point of departure is the realization that there are three areas which influence the management of the important, dynamic interface between R&amp;D and manufacturing. First, the level of outsourcing of manufacturing is increasing in many industries, which makes it even more demanding to manage the R&amp;D-manufacturing interface in complex product development. Second, complex product development may also be characterized by uncertainty and time-criticality, and previous research indicates that these factors need to be handled differently. Third, it is increasingly important to consider not only R&amp;D and manufacturing, but also field service requirements. The research methodology rests on a multiple case study approach where the main case used in this thesis is an extreme case in terms of uncertainty, R&amp;D intensity and volume levels, i.e. Micronic Laser Systems. The main findings of the thesis revolve around the identification of the challenges and solutions involved in complex product development. Based on five research papers, the thesis identifies challenges associated with each of the three research questions, and all challenges identified revolve around how to identify and understand conflicting requirements, to establish an understanding of changing prerequisites and their implications, and to ensure active involvement and a certain degree of competence overlap between organizational functions (internal as well as external). The solutions identified for handling these challenges have one thing in common, namely a focus on achieving controlled responsiveness and flexibility based on an understanding of tradeoffs, interaction, and informed decision-making. These solutions differ from those prescribed in conventional product development literature which tends to focus on upfront planning techniques and how to follow plans. The findings may be of value to a variety of managers in different environments, in particular for project managers who are involved in complex product development. The main reason is that this kind of product development exhibits challenges and solutions different from those described in conventional literature on new product development, at least in cases where there is some degree of uncertainty.

L’objectif de cette thèse est de contribuer au développement d’approches méthodologiques et d’outils informatiques pour développer les chaînes d’intégration numériques en entreprise étendue. Il s’agit notamment de mieux intégrer et d’optimiser les activités de conception, d’intégration et de simulation dans le contexte du développement collaboratif des produits/systèmes complexes.La maquette numérique (DMU) – supportée par un système de gestion de données techniques (SGDT ou PDM) – est devenue ces dernières années un environnement fédérateur clé pour échanger et partager une définition technique et une représentation 3D commune du produit entre concepteurs et partenaires. Cela permet aux concepteurs ainsi qu’aux utilisateurs en aval (ceux qui sont en charge des simulations numériques notamment) d’avoir un accès à la géométrie du produit virtuel assemblé. Alors que les simulations numériques 3D et 2D prennent une place de plus en plus importante dans le cycle de développement du produit, la DMU offre de nouvelles perspectives à ces utilisateurs pour récupérer et exploiter les données CAO appropriées et adaptées pour les analyses par éléments finis. Cela peut ainsi permettre d’accélérer le processus de préparation du modèle de simulation. Cependant, les environnements industriels de maquettes numériques sont actuellement limités dans leur exploitation par : - un manque de flexibilité en termes de contenu et de structure, - l’absence d’artefact numérique 3D permettant de décrire les interfaces des composants de l’assemblage, - un manque d’intégration avec les données et activités de simulation.Cette thèse met notamment l’accent sur les transformations à apporter aux DMU afin qu’elles puissent être utilisées comme données d’entrée directes pour les analyses par éléments finis d’assemblages volumineux (plusieurs milliers de pièces). Ces transformations doivent être en cohérence avec le contexte et les objectifs de simulation et cela nous a amené au concept de « vue produit » appliquée aux DMUs, ainsi qu’au concept de « maquette comportementale » (BMU). Une « vue produit » définit le lien entre une représentation du produit et l’activité ou le processus utilisant ou générant cette représentation. La BMU est l’équivalent de la DMU pour les données et les processus de simulation. Au delà des géométries discrétisées, la dénommée BMU devrait, en principe, lier toutes les données et les modèles qui seront nécessaires pour simuler le comportement d’un ou plusieurs composants. L’élément clé pour atteindre l’objectif d’élargir le concept établi de la DMU (basée sur des modèles CAO) à celui de la BMU (basée sur des modèles CAE), est de trouver un concept d’interface bidirectionnel entre la BMU et sa DMU associée. C’est l’objectif du « Design-Analysis System Integration Framework » (DASIF) proposé dans cette thèse de doctorat. Ce cadre a vise à être implémenté au sein d’environnements PLM/SLM et doit pouvoir inter-opérer à la fois avec les environnements CAD-DMU et CAE-BMU. DASIF allie les fonctionnalités de gestion de données et de configuration des systèmes PDM avec les concepts et formalismes d’ingénierie système basée sur les modèles (MBSE) et des fonctionnalités de gestion des données de simulation (SDM). Cette thèse a été menée dans le cadre d’un projet de recherche européen : le projet CRESCENDO qui vise à développer le « Behavioural Digital Aircraft » (BDA) qui a pour vocation d’être la« colonne vertébrale » des activités de conception et simulation avancées en entreprise étendue. Le concept du BDA doit s’articuler autour d’une plateforme collaborative d’échange et de partage des données de conception et de simulation tout au long du cycle de développement et de vie des produits aéronautiques. [...] / The aim of this doctoral thesis is to contribute to the facilitation of design, integration and simulation activities in the aeronautics industry, but more generally in the context of collaborative complex product development. This objective is expected to be achieved through the use and improvement of digital engineering capabilities. During the last decade, the Digital Mock-Up (DMU) – supported by Product Data Management (PDM) systems – became a key federating environment to exchange/share a common 3D CAD model-based product definition between co-designers. It enables designers and downstream users(analysts) to access the geometry of the product assembly. While enhancing 3D and 2D simulations in a collaborative and distributed design process, the DMU offers new perspectives for analysts to retrieve the appropriate CAD data inputs used for Finite Element Analysis (FEA), permitting hence to speed-up the simulation preparation process. However, current industrial DMUs suffer from several limitations, such as the lack of flexibility in terms of content and structure, the lack of digital interface objects describing the relationships between its components and a lack of integration with simulation activities and data.This PhD underlines the DMU transformations required to provide adapted DMUs that can be used as direct input for large assembly FEA. These transformations must be consistent with the simulation context and objectives and lead to the concept of “Product View” applied to DMUs andto the concept of “Behavioural Mock-Up” (BMU). A product view defines the link between a product representation and the activity or process (performed by at least one stakeholder) that use or generate this representation as input or output respectively. The BMU is the equivalent of the DMU for simulation data and processes. Beyond the geometry, which is represented in the DMU,the so-called BMU should logically link all data and models that are required to simulate the physical behaviour and properties of a single component or an assembly of components. The key enabler for achieving the target of extending the concept of the established CAD-based DMU to the behavioural CAE-based BMU is to find a bi-directional interfacing concept between the BMU and its associated DMU. This the aim of the Design-Analysis System Integration Framework (DASIF) proposed in this PhD. This framework might be implemented within PLM/SLM environments and interoperate with both CAD-DMU and CAE-BMU environments. DASIF combines configuration data management capabilities of PDM systems with MBSE system modelling concepts and Simulation Data Management capabilities.This PhD has been carried out within a European research project: the CRESCENDO project, which aims at delivering the Behavioural Digital Aircraft (BDA). The BDA concept might consist in a collaborative data exchange/sharing platform for design-simulation processes and models throughout the development life cycle of aeronautics products. Within this project, the Product Integration Scenario and related methodology have been defined to handle digital integration chains and to provide a test case scenario for testing DASIF concepts. These latter have been used to specify and develop a prototype of an “Integrator Dedicated Environment” implemented in commercial PLM/SLM applications. Finally the DASIF conceptual data model has also served as input for contributing to the definition of the Behavioural Digital Aircraft Business Object Model: the standardized data model of the BDA platform enabling interoperability between heterogeneous PLM/SLM applications and to which existing local design environments and new services to be developed could plug.
