Industry 4.0 has introduced technologies such as machine learning, Internet of Things (IoT), and cloud computing, which has disrupted markets across different industries. These technologies are prime examples of what has come to be known as disruptive innovations. With the advancement of disruptive innovations, organizations are constantly looking for new ways to satisfy customer needs. Therefore, organizations have begun to investigate alternative business models that differ from the conventional way of selling products/services. Within B2C-markets, the rise of subscription-based services has not gone unnoticed and has turned into a prominent business model among Fortune-500 organizations. Within B2B-practices however, subscription-based business models are mostly unheard of. Therefore, the purpose of this study was to examine how IndustryInternet of Things (IIoT) solution providers successfully can transition to a subscription-based business model when launching IoT-based disruptive innovations in industry 4.0 B2B-markets. This purpose was investigated in a quantitative study by constructing a questionnaire based on an adjusted six-factor Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model. The model was used to stipulate factors influencing buying intention for IoT-technologies. The study was further complemented by qualitative interviews, which aimed to shed more light on buyer's perception of subscription-based business models for IoT-technologies. The respondents consisted of purchasing function employees within the chemical-, food and beverage-, and life sciences industries in Scandinavia and the US. The quantitative results showed that performance expectancy had the most significant impact on buying intention. The qualitative results stipulated themes based on each UTAUT2 factor while also enlightening how interviewees emphasize the importance of not hiding costs and raised concerns regarding the transfer of data ownership when purchasing IoT-technologies. To conclude, the authors stipulated a conceptual framework for the implementation of subscription-based business models when introducing of IoT-technologies within B2B-markets.

There is an ongoing transition towards driverless trucks within the truck industry. However, there is limited research regarding the aftersales aspects of driverless trucks. Therefore, the purpose of this thesis project is to investigate expected challenges and current visions of the aftersales system for driverless trucks within the organization of Scania CV and Traton. The study aims to identify potential obstacles in the development of aftersales activities for driverless trucks in hub-to-hub contexts and proposes guidelines for managing the development. Hub-to-hub is defined as long-haulage transports between terminals. The thesis project covers several theoretical fields relevant to the subject, including product service systems, ambidextrous organizations, change management, visions within organizations, and handling ambiguity. The study was conducted by executing two field visits at Scania workshops to establish an understanding of the current aftersales system design, discussions with two experts within Scania CV, and two rounds of interviews with a total of 14 respondents from relevant departments at Scania CV and Traton to source empirical data on the current visions of an aftersales system for driverless trucks. The first round of interviews was mostly with upper managers and the second round with lower managers. According to the findings, there are various ambiguities and challenges regarding both technological and business-related aspects of the aftersales system design for driverless truck applications, establishing a need for collaboration between the concerned departments. There are differing visions between departments and within them. Various theories can support the collaboration process and handle ambiguity. Based on the empirical findings, a dissection of the current status quo is presented, and a discussion of how more favorable conditions for aftersales development can be induced. / Inom lastbilsindustrin pågår ett skifte till förarlösa lastbilar. Det finns dock begränsad forskning om eftermarknadsaspekterna av förarlösa lastbilar. Syftet med detta examensarbete är därför att undersöka förväntade utmaningar och nuvarande visioner för eftermarknadssystemet för förarlösa lastbilar inom Scania CV och Traton. Studien syftar till att identifiera potentiella hinder i utvecklingen av eftermarknaden för förarlösa lastbilar i linjetransport och föreslår riktlinjer för att hantera utvecklingen. Linjetransporter är defienrat som längre transporter mellan terminaler. Examensarbetet täcker flera teoretiska områden som är relevanta för ämnet, inklusive produktservicesystem, ambidextriska organisationer, förändringsledning, visioner inom organisationer och hantering av tvetydigheter. Studien genomfördes genom två fältbesök på Scania verkstäder för att skapa en förståelse för den nuvarande utformningen av eftermarknadssystemet, diskussioner med två experter inom Scania CV och två intervjuomgångar med totalt 14 respondenter från relevanta avdelningar inom Scania CV och Traton. Intervjuerna utfördes för att samla in empiriska data om de nuvarande visionerna för ett eftermarknadssystem för förarlösa lastbilar. Den första intervjuomgången var mestadels med högre chefer och den andra omgången med lägre chefer. Enligt resultaten finns det olika tvetydigheter och utmaningar när det gäller både tekniska och affärsrelaterade aspekter av utformningen av eftermarknadssystemet för förarlösa lastbilstillämpningar, vilket skapar ett behov av samarbete mellan de berörda avdelningarna. Det finns olika visioner mellan avdelningarna och inom dem. Olika teorier kan stödja samarbetsprocessen och hantera tvetydighet och med hjälp av den empiriska datan kommer en analys av den nuvarande samarbetsstrukturen presenteras. I kombination med detta kommer även förslag presentears gällande hur mer gynnsamma förutsättningar för eftermarknadsutveckling kan etableras.

Background. In today’s fast-paced business world, there is a notable shift from product-centric to solution-centric approaches driven by discussions around sustainability. This shift underscores the increasing demand for Product-Service systems as companies strive to adapt to evolving customer needs. Digital Twin-based approaches have emerged as a potential tool in this landscape, providing new methods for gathering customer insights. The construction industry is a crucial sector vital to economic growth, accounting for approximately 10 percent of the gross domestic product of many countries. However, it faces several challenges, including low productivity, unpredictability, and slow innovation. Objectives. The aim of this thesis is to propose a system that improves through-life support in heavy construction equipment. Additionally, the potential benefit of utilizing a Digital Twin for the development of Product-Service Systems will be suggested based on the developed system. Methods. In this thesis, the design approach was chosen to be Design Thinking to provide a structured framework that fits the uncertain and iterative process that the project demands. Furthermore, the tools and methods from Design Thinking were utilized to ensure the final solution was developed with creative support and constant concept feedback to address the user’s needs. Results. This thesis results in three potential areas of improvement in the through-life support of construction equipment, concepts that could address these, and the problem that is stopping their realization. Furthermore, a proposed solution to this problem has been developed that could enable the implementation of Digital Twins in construction equipment. Conclusions. This thesis finds that data collection issues prevent the implementation of Digital Twins in construction equipment. It also presents several potential strengths and weaknesses of Digital Twins in Product-Service System development.Additionally, it presents some future directions in Digital Twins and Product-Service Systems that need further work. / Bakgrund.

Comparé aux services traditionnels du secteur tertiaire, les services facilités par les technologies de l'information et des communications (ITeS, à partir du sigle en anglais, IT-enabled Services) suscitent un intérêt croissant de clients et fournisseurs d'une part du fait de l’automatisation des processus et d'autre part grâce aux nouveaux canaux de communication (Internet, réseaux mobiles, …) que ces services supportent. De ce fait, les ITeS co-créent de la valeur ajoutée due à la collaboration entre les clients et les fournisseurs lors de la conception et la livraison de services. Cet enrichissement des services traditionnels conduit à une remise à plat des méthodes actuelles de conception de biens et de services. En effet, elles ne permettent pas de répondre aux exigences imposées par ce contexte de collaboration multidisciplinaire qui intègrent les entreprises, les technologies de l'information et de la communication et les acteurs sociaux. Les caractéristiques intrinsèques des services (à savoir, l'intangibilité, l'inséparabilité, la périssabilité, la simultanéité) et leur nature sociotechnique requière à la fois une méthodologie de conception globale dirigée par les exigences des clients en vue de leur satisfaction et une approche systémique prenant en compte la dimension collaborative, le cycle de vie des services et les changements organisationnels, métiers et technologiques. Pour faire face à ces enjeux, nous proposons une méthodologie descendante pour modéliser et concevoir un système de services dirigé par les exigences des clients et supportant la collaboration entre tous les acteurs afin de permettre la co-création de ce système. Notre méthodologie repose sur une approche pluridisciplinaire et offre un ensemble de modèles interconnectés (modèle de référence de service, modèle d’exigence et modèle de collaboration) ce qui permet d’une part de donner de la flexibilité au système et de la rendre adaptable en cas de changements des exigences et d’autre part de supporter la collaboration entre tous les acteurs. Le modèle de référence offre une description des différentes dimensions du système de services (ontologique, caractéristiques et systémique) et explicite ainsi les connaissances liées aux domaines différents. En se basant sur le modèle d’exigences, les besoins du client sont spécifiés dans un langage commun et compréhensible par tous les acteurs. Ceci permet leur propagation dans tout le cycle de vie de service et leur diffusion à tous les acteurs. Le modèle de collaboration préconise une approche guidée par les données - une approche opposée aux processus métiers collaboratifs traditionnels - ce qui favorise l'interopérabilité technique et sémantique et augmente la stabilité du système face aux changements. Enfin, La collaboration s’appuie sur les canaux de communication qui engendrent des flux d'objets métiers selon lesquels des règles d'affaires sont générées afin d’invoquer les composants logiciels sous-jacents. / Compared to traditional business services, IT-enabled services provide more value to customers and providers by enabling traditional business services with Information and Communication Technologies (ICT) and delivering them via e-channels (i.e., Internet, Mobile networks). Although IT-enabled service systems help in co-creating value through collaboration with customers during service design and delivery, they raise challenges when we attempt to understand, design and produce innovative and intelligent IT-enabled services from a multi-disciplinary perspective by including businesses, technology and people for value addition and increasing benefits. Due to their social-technical nature and characteristics (i.e., Intangibility, Inseparability, Perishability, Simultaneity), IT-enabled services also lack common methods to systemize services driven by customer requirements and their satisfactions and co-produce them through ad-hoc collaboration. In this thesis, we propose a middle-out methodology to model, design and systemize advanced IT-enabled service driven by customer requirements and collaboration among all actors to jointly co-create service systems. From a multi-disciplinary perspective, the methodology relies on a multi-view models including a service system reference model, a requirement model and a collaboration model to ensure system flexibility and adaptability to requirement changes and take into account joint efforts and collaboration of all service actors. The reference model aims at a multi-disciplinary description of services (ontological, systematical and characteristic-based descriptions), and formalizing business knowledge related to different domains. As for the requirement model, customer needs are specified in common expressiveness language understandable by all service actors and made possible its top-down propagation throughout service lifecycle and among actors. The collaboration model advocates a data-driven approach, which increases busi-ness, technical and semantic interoperability and exhibits stability in comparison to business processes centric approaches. Finally, the collaboration hinges on de-livery channels expressed as data flows and encapsulating business artifacts as per which business rules are generated to invoke underlying software components.

No. of bitstreams: 1 Daniel Prujá.pdf: 3457554 bytes, checksum: c30ff99daedc1326eb7fcfa0181a4536 (MD5) Previous issue date: 2013-01-31 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / O objetivo desta dissertação de mestrado é discutir de que forma o Design Estratégico pode contribuir para evitar as experiências negativas relacionadas à comunicação verbal de estrangeiros não falantes da Língua Portuguesa no território brasileiro. O objeto de pesquisa é caracterizado pela oferta de turismo, considerando a sua afinidade de objeto de oferta como um Sistema Produto (que é o objeto de projeto do Design Estratégico), somado a sua característica como oferta mercadológica de experiência. Neste contexto, propõe-se um Sistema Produto Experiencial (SPE), um objeto de projeto que consiste na elaboração de uma oferta sistêmica entre produto, serviço, comunicação e distribuição, focada na experiência do usuário. Sua base encontra-se, além do Design Estratégico, na abordagem do Design e Emoção (uma abordagem focada no design para experiência através da análise das emoções do usuário). Para a elaboração do proposto SPE, foi estruturada uma pesquisa quantitativa ex-post-facto, com o objetivo de identificar os contextos em que os estrangeiros vivenciaram experiências negativas na comunicação verbal, mensurar a valência emocional dessas experiências negativas, e compreender sobre as suas causas. A análise deste diagnóstico sobre a experiência do usuário permitiu elaborar um conjunto de diretrizes projetuais para a discussão do potencial que um SPE oferece para evitar as experiências negativas deste público pesquisado. Conclui-se que a análise da experiência do usuário, materializada no SPE, ou seja, um sistema de oferta formulada pela estratégia de design focado na experiência do usuário, pode contribuir para evitar experiências negativas no contexto dos estrangeiros pesquisados. / This dissertation aims to discuss how the Strategic Design can help to avoid the negative experiences related to foreigners verbal communication who do not speak the Portuguese language in Brazil. The object of research is based on the tourism provision due to its affinity with the Product Service System (which is the project object of Strategic Design), plus its characteristic as marketing offer experience. In this context, it is proposed an Experiential Product Service System (EPSS), which is an object of design that consists in developing a systemic offer of product, service, communication and distribution, focused on the user's experience. Its basis, beyond the Strategic Design, is found in an approach focused on Design and Emotion (a focused approach to design for experience by analyzing the user's emotions). For the elaboration of the EPSS, a quantitative research ex-post-facto has been structured, in order to identify the contexts in which foreigners have faced negative experiences in verbal communication, measure the emotional valence of these negative experiences, and understand its causes. The analysis of this diagnosis on the user's experience, enabled to develop a set of project design guidelines for the discussion of the potential that an EPSS provides to avoid the negative experiences of the searched public. It has been concluded that the analysis of the user's experience, embodied in the EPSS, that is, a system formulated by offering design strategy focused on user's experience, can contribute to avoid negative experiences in the context of foreigners surveyed.

Evolution of the global economic system has significantly impacted on customer behaviors. The service economy era has accompanied rapid growth of the service industry. This work focuses on service innovation enhancement for cluster SMEs, which play important roles in the global economic system. These SMEs, which have specific knowledge and capabilities, are keys to improving customer service experiences. However, the entire service system has evolved, as have customer behaviors. In addition to understanding how service value is created, interactions between economic, social, and environmental systems during value creation are also crucial for the sustainable development of service industries. For service systems consisting of SMEs, the design of a value network for clustered SMEs still faces huge challenges in finding key value propositions and assessments for value creation. To assess service value, relationships, and customer feedback from both economic and social psychology perspectives, this research proposes a novel service ecosystem for value creation in service dominant logic and customer-driven and imagery-based value network design approach (CIVNDA) grounded in service dominant logic and image theory. The CIVNDA (1) provides a framework for designing and configuring a service value network that can identify the roles and value propositions of each partner; (2) provides a novel service imagery representation to characterize services of businesses from a customer psychological perspective; and (3) generates appropriate partners for specific cooperation goals and service journey designs. Due to the importance of information technology in service innovation, integration, and provision, this research also implements an ICT-based service platform—uVoyage using color image scale and metaphor theory. Tourism is selected as the study industry to evaluate the effects of the CIVNDA and the uVoyage service platform. Interview and focus group results (1) show that four different evolutionary stages of tourism SMEs exist when adapting to the current service economy era; (2) indicate how the CIVNDA and uVoyage platform facilitate value co-creation for tourism SMEs during different evolutionary stages; and (3) demonstrate how the features of service imagery differ from brand images and can be utilized to bridge gaps between product design and customer-driven service design. This research can contribute to our understanding of service system ecology and service value evaluation in service value network designs consisting of SMEs in the tourism, design, cultural, and creativity service industries. The proposed concept of service imagery also guides future innovative research and outcomes of service value network design.

產品服務系統的概念是在八十年代被提出,當時基於國際化導致各國產業日趨競爭,企業因而積極尋求更多的途徑來創造成長,而當時許多企業,如: IBM、Xerox 等,由原本的產品銷售事業逐漸 跨足服務的提供,這帶給這些企業許多市場競爭優勢,進而促使更 多不同產業的企業開始應用類似的策略實施。 有鑑於國內產業目前積極地推廣產品服務系統,以創造各個領域的產業升級,因此本研究以產品服務系統的供應鏈管理做為討論的核心,希望了解企業在產品服務系統的落實中,應如何應對這商 業模式的變化。對此,本研究採用個案研究法,首先透過文獻探討 以整理出研究的分析模型,再配合產品服務系統實施成功的國內傢 俱零售廠商做為研究個案,以進行調查。其中,分析模型主要由三個面向所構成,分別為下游供應網絡、焦點企業與上游供應網絡 , 並且在下游供應網絡的環節重點討論企業與顧客的互動模式,在焦 點企業的部分探討企業內部的管理措施,而在上游供應網絡探究企業與供應商的合作模式。 本研究發現產品服務系統的採行會直接地改變企業與顧客之間的互動關係,這促使企業必須與顧客進行密切的溝通,同時還需要積極獲取顧客的資訊。而由企業內部角度來看,則需要創造服務能力,調整績效管理模式,以及培養服務導向的組織文化。最後,企 業應與供應商應建立作業連結、資訊共享管道與誘因同盟,使彼此促成長期的合作關係,並讓整合方案能夠更效率地傳遞給顧客。 本研究透過實際案例的深入探討,了解到企業在執行產品服務系統的過程中,對於供應鏈採行了何種管理因應,其結果不但擴充 了“產品服務系統供應鏈”的理論探討,同時能夠也提供給未來相關領域的研究者與其他相關企業發展的參考。 / The concept of Product Service System (PPS) has been expanded since 1980s, when the globalization boosted the competition of various industries. Therefore, companies were longed to explore new business model to facilitate their performance within the market and at that period several companies (including IBM, Xerox) successfully obtained outstanding competitive advantages through providing service, which is derived from their product business, and formed the idea of PPS and Servitization. And so, more and more companies involve in PPS, hence PPS have already applied in numerous industries nowadays. Previously, Taiwan’s local market put a lot of emphasis on PPS, in order to promote upgrade in various industries. Therefore, this paper is aim to discover implementational insight of PSS in the perspective of supply chain management (SCM) and realize how should company responds, when facing the change of business model. In this case, this paper utilize case study methodology with analysis model, which is contrived by desk research on PPS supply chain related paper, and execute in-depth analysis on case study of local furniture retailer, which possess successfully experience in PPS. In this research, the analysis model is consisted with three major dimensions, that is upstream supply network, focal company and downstream supply network. In the aspect of upstream supply network will focus on the discussion of customer interaction, but when it comes to the aspect of focal company will put emphasis on inner management and last would be the dimension of downstream supply network with understanding of supplier relationship management in the background of PPS. The research results indicate that the application of PPS would bring direct change on the interrelationship of customer and focal company, this would cause the company to have frequent communication with customer and shall obtain customer information during interaction. And in the viewpoint of focal company, it should alter the performance evaluation model and acquire new ability of service and service-oriented culture. Last but the least, focal company should establish comprehensive operational linkages, information sharing methods and incentive alignment with supplier to deliver integrated solution to the customer efficiently. With in-depth case study, this paper unveils the SCM detail information of Servitization and the result is not only contributive toward the academic research of PPS, but also provides valuable insight for industry with further expansion on PPS.

Cette thèse contribue à la compréhension d’un phénomène émergent et complexe : la transformation/smartisation du système de service public urbain. Cela comprend la combinaison de différents secteurs de services tels que les transports, le tourisme,les taxes, etc. Du point de vue conceptuel, nous établissons trois piliers pour la Science du Service : Système de service (SS), Innovation de Service (IS) et Logiques Institutionnelles de Service (LIS). Nous commençons par proposer une méthode basée sur l’analyse sémantique latente (LSA), l’analyse factorielle (FA), le text mining et la théorie enracinée. Il s’agit de mettre en évidence de manière inductive et interdisciplinaire, 30 années d’évolution de la structure intellectuelle de SS, IS et LIS, de 1986 à 2015. Ceci nous a permis d’étudier les théories associées à ces thèmes, dans plusieurs domaines dans le temps. Grâce à cette étape, nous avons pu justifier le choix de deux théories permettant d’étudier la dynamique de la transformation institutionnelle et structurelle d’un système de service : 1) la théorie du travail institutionnel entre logiques collectives, antagonistes, et complémentaires, et 2) la pensée complexe. La théorie du travail institutionnel nous a permis de mettre en évidence le processus de transformation des arrangements institutionnels. La pensée complexe, comme cadre intégrateur, nous a permis de mettre en évidence le contenu, ou les effets, de la transformation institutionnelle, en considérant le tout et les parties d’un système de service public urbain qui devient smart. L’architecture de la recherche est basée principalement sur la théorie enracinée, l’observation, les archives, l’étude de cas longitudinale multiniveaux (i.e. locale et nationale) via le modèle dialogique(Parmentier-Cajaiba & Avenier, 2013) et le paradigme épistémologique constructiviste pragmatique (PECP). Aussi, nous utilisons deux hypothèses ontologiques du travail : l’ontologie relationnelle et l’ontologie du devenir. Du point de vue théorique, notre recherche contribue au affinement théorique de la littérature sur SS, IS et LIS en proposant une définition du construit "système de service public urbain smart". Cette définition est accompagné de trois modèles heuristiques résultants d’une analyse par le processus et par le contenu de la transformation et de la théorie enracinée (Gioia & Chittipeddi, 1991 ; Gioia et al., 2013). Le premier modèle heuristique contribue à la compréhension du processus de travail institutionnel pour la co-création d’arrangements institutionnels (i.e. standard, normes, les ressources frontières, APIs) entre deux logiques collectives antagonistes et complémentaires (Morin, 2005 ; Smets & Jarzabkowski, 2013 ; Greenwood et al., 2017) : la logique de service dominant du marché (Lusch & Nambisan, 2015 ; Vargo & Lusch, 2016) et la logique du service public (Osborne et al.,2015 ; Osborne, 2017). Le deuxième modèle heuristique met en évidence les composantes structurales d’un système de service public qui devient smart. Le troisième modèle heuristique souligne les moteurs et les freins de la transformation institutionnelle et structurelle. / This thesis contributes to the understanding of an emergent and complex phenomenon: transformation/smartization of the urban public service system. This involves innovative, context-sensitive and interoperable public service systems, as well as the cross combination of different services sectors such as transport, tourism, taxes, etc. We define three pillars of service science : Service System (SS), Service Innovation (IS) and Institutional Service Logic (LIS) in order to develop a process and content research to understand the dynamics of urban public service system institutional and structural transformation. We propose a method based on Latent SemanticAnalysis (LSA), Factor Analysis (FA), text mining and grounded theory to inductively reveal 30 years of evolution of interdisciplinarySS, IS and LIS intellectual structure from 1986 to 2015. In particular, we analyze the process of institutional work between antagonisticand complementary collective logics. Then, we mobilize complex thinking as an integrating framework of components of the urban publicservice system that becomes smart, as a whole and its parts. Our research design is based on grounded theory ; observations, longitudinalcase study with a multi-level approach (i.e. local and national) ; the dialogic model(Parmentier-Cajaiba & Avenier, 2013) and the pragmaticconstructivism epistemological paradigm (PECP). We define two working ontological hypotheses : the relational ontology and becomingontology. From the theoretical point of view, our research contributes to the theoretical refinement of the literature on SS, IS and LIS. Wepropose three heuristic models from a process and content analysis (Baines et al. 2017) and grounded theory (Gioia & Chittipeddi, 1991 ;Gioia et al., 2013). The first heuristic model contributes to the understanding of the institutional work process for the creation of institutionalarrangements (Standard, boundary resources, APIs) between two antagonistic and complementary collective logics (Morin, 2005 ; Smets & Jarzabkowski, 2013 ; Greenwood et al., 2017) : the service-dominant logic of the market (Lusch & Nambisan, 2015 ; Vargo & Lusch, 2016)and the public service logic (Osborne et al., 2015 ; Osborne, 2017). The second heuristic model highlights components of a smart publicservice system. The third heuristic model highlights the drivers and barriers of institutional and structural transformation.

Abstract There are multiple factors simultaneously affecting speech perception in elderly people. These factors include hearing acuity, aging of the auditory system, and changes in both perception and cognitive processes, all of which can interfere with speech comprehension, especially in cognitively demanding situations. The aim of this study is to clarify which factors influence the use of an automatic phone service system designed for elderly (N = 36) people. More specifically, the aim is to investigate whether it is the factors connected to the system itself or the factors connected to the elderly users and their actions with the system that are the most crucial for using the system successfully. Both quantitative and qualitative methods are used in the study. There were four people who performed as speakers in the system. Analysis of the prosodic features of their speech was performed using acoustic analysis software. The variables connected to the elderly participants (n = 30) were investigated using interviews, pure-tone and speech audiometric tests, the Mini-Mental State Examination test (MMSE), and the Token Test for speech comprehension. Statistical analyses were used to explore whether there was a statistical connection between the acoustic measurements or the variables connected to participants themselves and their performance in usability test situation. In addition, the elderly participants’ actions in the test situation were observed using a material-based, qualitative video-analysis. The individuals who performed as speakers in the system were observed to use features of elderspeak in their speech. However, these speaker characteristics had little effect on the participants’ performance in the tasks. It was the voice-menu that contained the most semantically complex text structure that proved to be the most difficult for participants. Both low scores in the Token test and poor word recognition were connected to poor performance in the tasks. It was found based on the qualitative analysis that in addition to speech comprehension, there were other cognitive processes that were important for completing the tasks successfully, i.e. remembering the instructions given (memory), and the ability to direct, divide and maintain attention during the tasks. Poor performance in the tasks and in the Token Test, as well as problems in executive functions observed in the test situation, were found to be factors predicting dropping out of the next phase of the study the following year. Qualitative analysis of language use in cognitively demanding situations can be used in evaluation of high-level language performance. It may be useful for detecting mild changes in language skills that can be symptomatic of early stages of memory disorders. The results of this study can also be utilized when designing voice-based interfaces. In addition, it is important to consider both advantages and disadvantages of using elderspeak in the fields of nursing and speech therapy. / Tiivistelmä Ikääntyvien ihmisten puheen vastaanotossa vaikuttavat samanaikaisesti monet tekijät: kuulokyky, auditiivisen järjestelmän ikääntymismuutokset sekä havaintotoimintojen ja kognitiivisten toimintojen muutokset. Nämä voivat vaikeuttaa puheen ymmärtämistä erityisesti kognitiivisesti vaativassa tilanteessa. Tämän tutkimuksen tavoitteena on selvittää ikääntyneille osallistujille (N = 36) suunnitellun automaattisen puhelinpalvelujärjestelmän käyttöön liittyviä tekijöitä. Tavoitteena on selvittää se, missä määrin toisaalta kokeiltuun järjestelmään liittyvät tekijät ja toisaalta käyttäjien ominaisuudet sekä heidän toimintansa tutkimustilanteessa olivat yhteydessä järjestelmän menestykselliseen käyttöön. Tutkimuksessa käytetään kvantitatiivisia ja kvalitatiivisia menetelmiä. Järjestelmässä kokeiltiin neljän eri puhujan äänillä nauhoitettuja toimintaohjeita. Heidän puheensa prosodisia piirteitä analysoitiin äänen ja puheen analyysiohjelmilla. Ikääntyneisiin osallistujiin (n = 30) liittyviä muuttujia tutkittiin haastattelulla, kuulon tutkimuksilla (äänesaudiometria ja puheaudiometria), kognitiivisella seulontatestillä (Mini-mental state examination = MMSE) ja puheen ymmärtämistä mittaavalla Token-testillä. Mittaustulosten ja muuttujien yhteyttä tehtävistä suoriutumiseen tarkasteltiin tilastollisesti. Osallistujien toimintaa havainnoitiin järjestelmän käyttötilanteessa aineistolähtöisellä laadullisella videoanalyysillä. Järjestelmän puhujilla havaittiin ikääntyneille suunnatun puheen piirteitä. Tehtävistä suoriutuminen oli kuitenkin hyvin samanlaista puhujasta riippumatta. Semanttisesti monimutkaisin tekstivalikko oli osallistujille vaikein äänite. Matala Token-testin pistemäärä ja heikko puheen tunnistuskyky liittyivät heikkoon tehtävistä suoriutumiseen. Laadullisen analyysin perusteella puheen ymmärtämisen ohella keskeisiä kognitiivisia prosesseja tehtävissä menestymisen kannalta olivat seuraavat: ohjeiden muistaminen, huomion suuntaaminen, jakaminen ja ylläpito. Heikko suoriutuminen tehtävissä ja Token-testissä sekä tutkimustilanteessa havaitut toiminnan ohjauksen ongelmat ennustivat toisesta tutkimusvaiheesta poisjääntiä seuraavana vuonna. Kognitiivisesti vaativista kielen käyttötilanteista tehtävillä laadullisilla analyyseilla voidaan arvioida monimutkaisia kielellis-kognitiivisia toimintoja ja löytää mahdollisesti alkaviin muistisairauksiin liittyviä lieviä kielellisiä muutoksia. Tuloksia voidaan hyödyntää ääneen perustuvien käyttöliittymien suunnittelussa. Ikääntyneille suunnatun puheen etuja ja haittoja on tärkeää pohtia myös hoitotyön ja puheterapian näkökulmasta.
