Today's society is characterized by a high degree of change where the manufacturing systems are affected by both internal and external factors. To adapt to current manufacturing requirements in the form of short lead-time, more variants, low and fluctuating volumes, in a cost-efficient manner, new approaches are needed. As the global market and its uncertainties for products and its lifecycles change, a concept called 'reconfigurable manufacturing system' has been developed. The idea is to design a manufacturing system for rapid structural change in both hardware and software to be responsive to capacity and functionality. A company's development towards the concept is often based on a strategy of incremental investments. In this situation, the challenges are to prioritize the right project and maximize the performance as well as the financial efficiency of a multi-approach problem. The report is based on three different issues. Partly how to standardize relevant performance-based metrics to measure current conditions, how new performance-based metrics can be developed in collaboration with reconfigurability characteristics, and set a direction for how decision models can be used to optimize step-based investments. The study is structured as an explorative study with qualitative methods such as semi-structured interviews and document study to get in-depth knowledge. Related literature addresses concepts in search areas such as reconfigurable manufacturing system, key performance indicators, investment decisions, and manufacturing readiness levels. The findings are extracted from interviews and document studies that generate a focal company setting within the automotive industry, which acts as the foundation for further analysis and decisions throughout the thesis. The analysis results in sixteen performance measurements where new measures been created for product flexibility, productionvolume flexibility, material handling flexibility, reconfiguration quality and diagnosability using reconfigurability characteristics. A conceptual decision support model is introduced with an underlying seven-step investment process, analyzing lifecycle cost, risk triggered events in relation to cost, and performance measurements. The discussion chapter describes how different approaches are used during the project that has been revised by internal and external factors. Improvement possibilities regarding method choice and the aspects of credibility, transferability, dependability, and conformability are discussed. Furthermore, the authors argue about the analysis process and how the result has been affected by circumstances and choices. The study concludes that a three-pronged approach is needed to validate the investment decision in terms of system performance changes, cost, and uncertainty. The report also helps to understand which performance-based metrics are relevant for evaluating manufacturing systems based on operational goals and manufacturing requirements.

I samarbete med Skanska Sverige AB, Region Hus Stockholm Bostäder har detta examensarbete upprättats. Examensarbetet handlar om bedömning och uppföljning av de allmänna kostnaderna, (AK), inom regionen.  Inom husbyggnation är de allmänna kostnaderna en del av projektets totalkostnad och är i de flesta fall svåra att beräkna. Delar av Region Hus Stockholm Bostäder har arbetat med att ta fram erfarenhetsvärden och nyckeltal, för att få ökade kunskaper om AK i projekten och därigenom underlätta bedömningarna för prissättning i kommande projekt. Syftet är att försöka bidra till högre produktivitet genom att göra bättre bedömning, uppföljning och erfarenhetsåterföring med hjälp rekommendationer. Målet är ta fram en generell beskrivning av en rekommenderad arbetsrutin som ska ha en ”best practice” funktion för framtida arbeten.  Materialet som detta examensarbete baseras på är en sammanställning av intervjuer med olika personer inom Skanska Sverige AB, inom Region Hus Stockholm Bostäder och Region Hus Stockholm Kommersiellt. Jämförelse görs mellan bostadsprojekt inom regionerna. Information har även hämtats från litteratur och Skanskas hemsida. Arbetsrutinerna inom regionen varierar till viss del. Beräkning av AK görs på samma sätt över regionen, dock är uppföljningen personlig och varierande i strukturen under produktionsskedet. Detta gör att i dagsläget är arbetet personberoende och inte processberoende. Rekommendationerna presenteras i form av en arbetsbeskrivning och en erfarenhetsåterföringsmodell. Arbetsbeskrivningen omfattar de viktigaste delarna i arbetet med AK under anbudsskedet, produktionsskedet samt vid projektavslut. Erfarenhetsåterföringsmodellen behandlar hur de befintliga erfarenheterna kan återföras i företaget. Vidare förelås även en utveckling av projektstyrningsverktyget SPIK att agera som informationsbärare för att kunna ta sammanställa säkrare nyckeltal samt en stabil erfarenhetsbank. Vidare förelås även ytterligare utveckling av projektstyrningsverktyget SPIK, för att agera som informationsbärare och därefter kunna ta sammanställa säkrare nyckeltal samt en stabil erfarenhetsbank. / This thesis was established in collaboration with Skanska Sweden AB, Region Hem Stockholm Bostäder. The thesis deals with the assessment and monitoring of the general costs in the region. AK is a part of the project's total cost in house building and is in most cases difficult to estimate. Parts of the Region House Stockholm Homes have been working to develop empirical values and key performance indicators, to gain greater knowledge of the general costs in the projects, thereby facilitating the estimation of pricing in future projects. It aims to contribute to higher productivity by making better assessment, monitoring and feedback with recommendations. The goal is to develop a general description of a recommended practice is to have a "best practice" function for future works. This thesis is based on material from a compilation of interviews with various people at Skanska Sweden AB, Region Hus Stockholm Bostäder and Region Hus Stockholm Kommersiellt. Comparison is made between the housing construction projects in the regions. Information was also gathered from literature and Skanska´s website. The working procedures within the region vary to some degree. Calculation of the general costs is similar across the region; however the follow-up is personal and vary in process during the production phase. This means that in the current situation is the work is depending on individuals rather than process. The recommendations are presented in the form of a job description and an experience feedback model. The job description includes the main elements in the work of the general costs during the tendering stage, production stage and at project completion. The model for experience feedback addresses how existing experience can be brought back into to the company. Furthermore, it is proposed also a development of the project management tool SPIK to act as an information carrier, and with it produce more reliable key performance indicators and create a solid bank of experiences.

Bakgrund och problem  Det har blivit mer vanligt att räkna på de mänskliga resurserna i organisationer, vilket har lett till att HR-avdelningen har fått en mer strategisk roll och tagit avstånd från att bara varit en administrativ stödfunktion. Människor är de som organiserar beslutsfattning och agerar utefter beslutsproblem varav det behövs kompetent personal, regler och struktur. Beslutsprocesserna genomgås ofta med en vision av vad önskat resultat ska bli vilket ofta går i enlighet med organisationens mål. Personalnyckeltal används av alla organisationer i någon mening. Vanligtvis i ett jämförande syfte från tidigare år, till andra konkurrenter eller för att se trender. De bidrar till att föra organisationen framåt mot de uppsatta målen. Det mänskliga kapitalet är svårare att räkna på än andra immateriella tillgångar, men att ändå kunna använda sig av personalnyckeltalen i beslutsprocesser bör därför kunna resultera i en mer tydlig process. Syfte och metod  Syftet med studien var att utöka den teoretiska och praktiska kunskapen om betydelsen personalnyckeltal har i organisationers beslutsprocesser. För att undersöka detta tillämpades därför en kvalitativ metod där fem semistrukturerade intervjuer genomfördes med intervjupersoner från både privat och offentlig sektor.  Resultat och slutsats Studien resulterade i en ökad teoretisk och praktisk kunskap då personalnyckeltal har en betydelse för organisationers beslutsprocesser i de faser där de agerar som underlag. Det är ytterst viktigt att använda sig av siffror som personalnyckeltal när en organisation identifierar ett problem, samlar in information till beslut och sedan utvärderar den process som genomförts och det beslut som implementerats. / Background and problem Accounting for the human resources within organizations have become more common which have led to a more strategic role for the HR-department and a departure from its original role as a supportive administrative part of the organization. Humans are the ones who organize decision making and therefore act along the problems of the decision where competent personnel, rules and structure are needed. The decision-making processes are often undergoing with a vision of what the wanted result is which often is in conjunction with the goal of the organization. All organizations have use of key performance indicators in some capacity. It´s commonly used with a comparative purpose in contrast of previous years, comparing key performance indictors to other competitors or to spot trends. They contribute to bring the organization towards its goals. The human capital is harder to account for than other intangible assets, but to be able to use key performance indicators in decision-making processes should therefore result in a more distinct process.  Purpose and method  The purpose of this study was to expand the theoretical and practical knowledge of the significance that key performance indicators have in organizational decision-making processes. A qualitative method was therefore used where five semi structured interviews were conducted with interviewing persons from both the private and public sector. Results and conclusion  This study resulted in an increased theoretical and practical knowledge in that key performance indicators have a significant matter in organizational decision-making processes in those phases where they act as a groundwork. It is of utmost importance to use digits like key performance indicators when an organization identifies a problem, collects information to be used for the decision and later evaluates the previous process and the decision that has been implemented.

The energy system is undergoing a transformation on a never before witnessed scale. The changes are driven by global market forces and technological advancements, improving on a seemingly exponential scale. This in turn has led to the price of both renewables and the accompanying technology decrease over time, making the transition into renewables more economically viable. The drawback of variable renewable energy is that it is variable and dependent on the surrounding environment. Therefore, storing the energy during hours of production, to be used at a later stage when energy demand is higher is becoming ever more important and an attractive option. The purpose of this degree project is to, from a set of performance indicators, evaluate three different energy storage technologies and their respective impact on a distribution grid. The examined storage technologies are: Batteries, Capacitators and a H2 Fuel cell. A literature study was performed in order to find out how grid performance is evaluated, and how the different storage technologies operate. The obtained literature comes from scientific reports, and papers, found by utilizing Mälardalens University library-database. A model representing a Swedish grid with a connection point to the distribution side was created. The model is taken from previous credited work, and customized to fit the operational parameters of a Swedish grid. It was decided that the key indicators for evaluating the state of a grid was to look at the: voltage- and frequency variations, load factor, capacity factor and the overall system efficiency. The simulation is a discrete time simulation that utilizes parameters indicative of one full day of data. The results showed that, from a technological standpoint, the supercapacitor performed better in more categories than the Li-ion battery and H2 fuel cell. However, the Li-ion battery reduced the peaks of the frequency measurements which is a key metric when deciding on grid health. Also, there is the added benefit of the battery and fuel cell of having a longer operational time before the state of charge is depleted. This increases the flexibility of the technology and could therefore be more beneficial in other applications where power supply is more scarce.

Der 39. Band der Leipziger Beiträge zur Informatik setzt sich mit den Herausforderungen im Zusammenhang mit der zunehmenden Industrialisierung der Dienstleistungswirtschaft auseinander.

Combining products and services into Product-Service Systems (PSS), which are often owned and even operated by the company offering them, is seen as an important element of conducting more sustainable business. The prospective environmental benefits of PSS lie mainly in the improved resource- and operational efficiency. This is achieved by way of a critical shift in incentive structure: If an industrial company assumes responsibility for an offering throughout the lifecycle, the terms on which that company operates are changed substantially in comparison to traditional product sales. Instead of benefiting from a short lifetime through additional sales opportunities or making profit through the sale of spare parts, in highly integrated PSS, each parts exchange, each technicians’ visit and each day the lifetime of the offering is reduced directly affects the bottom line of the provider. Due to that, solely as a result of economic rationality, a provider of these offerings has an incentive to design in such a way that the life of this offering is prolonged, need for spare parts is reduced, service activities are facilitated and simplified, and that the conditions are in place to allow for a second or third life of the offering through remanufacturing. Regardless of this compelling logic, at times, industrial companies fail to establish the preconditions to capturing these benefits as they continue to rely on product and sales-centric design processes even though they provide PSS. This thesis aims to examine this unexploited opportunity from two vantage points. On the one hand, methods conceived in academia to support industry in implementing and executing joint, lifecycle-focused design of products and services, and the use of these methods in practice, are examined. Here, the focus firstly lies on understanding how PSS are designed today, and secondly, on what should change about PSS design methods to improve their implementability and usability in industrial practice, so that they can fulfill their supposed role as facilitators of efficient PSS design and operation. On the other hand, the possible benefits of providing specifically designed and lifecycle-focused PSS as an industrial company are in focus. To this end, the value attained by providers throughout the use phase of PSS is investigated, to then identify possible approaches towards enhancing this value. Eventually, both focus-areas are joined in an effort to examine the interaction between method-supported, lifecycle-oriented PSS design and the value attained by providers of such offerings. As a result of the research, a lacking adaptation of design processes to PSS is identified in the case companies. Further, shortcomings of PSS design methods conceived in academia, e.g. excessive complexity, lacking clarity and rigidity, are found in both literature as well as in a study with an industrial company. To take a first step towards rectifying this issue, six characteristics intended to enhance implementability and usability of PSS design methods, are presented. The value attained by PSS providers has been found to be a complex but important subject. In a case study, value determinants of high relevance to the use phase of the lifecycle have been identified and assessed for their utility as indicators in the evaluation and enhancement of PSS offerings in the design phase. The practitioners involved were supportive of the applicability of the systematic approach presented to capture more value through offering PSS. In joining both the value- and method-oriented approach, the mutual dependency of both aspects is discussed. In order to provide PSS in an economically and environmentally efficient fashion, adapting the existing design processes is imperative. The value attained by the provider can, complementary to existing customer-centric approaches, serve as an important goal for the adaptation of design processes. Ultimately, through understanding the change in incentive structure at the core of PSS, and through implementing a value-driven design process supported by efficient and effective methods aimed at providing both customer value and capturing provider benefits throughout the lifecycle, there is a genuine potential of conducting more sustainable business.

Un Service d’urgence (SU) est le service hospitalier ayant comme responsabilité de fournir des soins non programmés à une grande variété de patients, 24 heures sur 24, 7 jours sur 7. Les SU sont actuellement confrontés à un problème international et récurrent, à savoir la saturation des urgences qui résulte de l’actuelle inadéquation entre les capacités médicales et la demande des patients. L'objectif est de développer des solutions internes et économiques permettant d’atténuer le phénomène de saturation des urgences et d’améliorer leur performance, à l'aide de méthodes issues de la Recherche Opérationnelle/Gestion des Opérations (RO/GO). Ces solutions sont d'un grand intérêt pour les gestionnaires. Afin d'atteindre cet objectif, nous abordons trois ensembles de questions de recherche.La première catégorie comprend des questions prospectives portant sur les indicateurs clés de performance (ICP) ainsi que sur les différents facteurs contribuant à l’encombrement des urgences. La deuxième catégorie est constituée de questions liées au dimensionnement de la capacité des ressources humaines dans un SU. Un modèle réaliste de simulation à événements discrets des urgences est élaboré. En utilisant l'optimisation basée sur la simulation, la durée moyenne de séjour des patients (LOS) est minimisée, en intégrant une contrainte budgétaire ainsi qu’une contrainte assurant que les patients les plus critiques accèderont à un médecin dans un délai déterminé. Les résultats obtenus permettent de fournir aux gestionnaires des urgences des indications utiles sur l'impact du budget sur la performance et sur la manière dont les investissements devraient être priorisés et répartis entre les ressources, ainsi que sur l'effet de la prise en compte de deux principaux ICP différents. Nous proposons également une heuristique pour l'optimisation de la structure des shifts (roulements) du personnel dans la journée. La méthode combine l'optimisation basée sur la simulation avec de la programmation linéaire. La troisième catégorie de questions porte sur le processus de soins des patients. Nous analysons des modifications et des alternatives innovantes dans le parcours du patient (à budget fixe). Typiquement, dans les pratiques actuelles, chaque patient dans un SU est affecté à un seul médecin qui en sera exclusivement responsable pendant toutes les étapes du processus (règle du "Même Patient Même Médecin", MPMM). Dans un premier temps, nous menons une enquête auprès des praticiens qui confirme que MPMM représente la pratique standard dans la plupart des SU à travers le monde. L’enquête révèle également que la suppression de cette règle est très controversée parmi les urgentistes. Nous utilisons ensuite une modélisation en réseau de files d’attente Erlang-R contenant une complexité additionnelle. Nous montrons et quantifions les avantages potentiels de la suppression de la restriction MPMM en fonction des paramètres du système. Une seconde étude portant sur le processus est menée, à savoir la prescription des examens par l’infirmière chargée du tri (PIT) avant la consultation initiale. Nous comparons le fait d’autoriser l’infirmière à prescrire certains examens complémentaires, avec la procédure standard consistant à attendre que le médecin examine le patient et lui prescrive des examens. Nous démontrons l'efficacité de PIT sur la performance du SU en fonction de paramètres clés, tels que le niveau de compétence de l’infirmière, la charge du système et l'extension de la durée du tri.De manière générale, cette thèse aborde d’innovantes questions de recherche dans la gestion des opérations des SU. Elle fournit aux décideurs des recommandations et des outils permettant d’améliorer la performance des urgences. Cette thèse ouvre également la voie pour de futurs axes de recherche liés à l'optimisation des opérations dans les SU. / Emergency Department (ED) is the service within hospitals responsible for providing unscheduled care to a wide variety of patients over 24 hours a day, 7 days a week. As a result to the existing mismatch between available caring capacity and patients demand, EDs are currently facing a recurrent worldwide problem, namely overcrowding. The objective of this thesis is to develop internal and cost-effective solutions to alleviate overcrowding in EDs and improve their performance, using Operations Research/Operations Management (OR/OM) methods. Such solutions are of great interest for managers. In order to achieve this objective, we address a series of research questions.The first category of research questions include prospective questions about ED Key Performance Indicators (KPIs) and about the diverse factors contributing to overcrowding. We first conduct a detailed literature review on the commonly used KPIs from an OR/OM perspective. The review summarizes the advantages and drawbacks of each KPI and provides several useful insights. In addition, a series of statistical analysis are performed in the purpose of identifying the main influencing factors of performance.The second category consists in resource-related questions that are associated to the dimensioning of ED resource capacity. A realistic ED discrete-event simulation model is thus proposed. The model accounts for the most essential structural and functional characteristics of EDs thanks to a close collaboration with practitioners. Using simulation optimization, we minimize the patient average length of stay (LOS), by integrating a staffing budget constraint and a constraint securing that the most severe incidents will see a doctor within a specified time limit. The obtained results allow us to provide useful insights to managers about the impact of the budget on performance and how investments priorities should be allocated among resources, as well as the effect of combining two different major KPIs. Furthermore, we propose a heuristic for the optimization of the shifts of human resources. The method combines simulation optimization and linear programming.The third category of questions deals with process-related issues. We investigate potential alternative and innovative ED patient flow designs (with fixed budget). Typically in current ED practices, each patient is assigned to a single physician who will be exclusively responsible of him/her during all stages of the process (“Same Patient Same Physician”, SPSP rule). We conduct a survey which confirms that SPSP stands as the standard practice in most EDs worldwide, and that removing SPSP rule is very controversial among practitioners. We next use a complexity-augmented Erlang-R queueing network modeling. We show and quantify the potential benefits of removing the SPSP restriction as a function of the system parameters. For a second process-related issue, we compare the Triage Nurse ordering (TNO) diagnostic tests against the standard procedure, i.e., waiting for the physician to examine the patient and order tests. We demonstrate the efficiency of TNO on ED performance as a function of key parameters, such as triage nurse ability, system load and triage time extension.In summary, this thesis addresses innovative OM research questions for EDs. It provides decision makers with recommendations and tools in order to improve ED performance. It also highlights various avenues for future research related to the optimization of ED operations.

Bakgrund och syfte: Implementeringen av HR analytics är mycket låg trots att forskning visar på att användandet av HR analytics leder till bättre beslut i organisationer. Syftet med studien var att undersöka HR analytikers uppfattning av hinder bakom den begränsade framväxten. Metod: Sex HR analytikers semistrukturerade intervjuer analyserades genom en tematisk analys. Analysen var induktiv med inslag av deduktion. Resultat: Det råder en kompetensbrist inom området. Hinder för framväxten har visat sig vara HR analytikers tvivel på sin egen förmåga att arbeta databaserat, brist på ledningsstöd, brister i mjukvara, kompetens- och utbildningsbrist samt informationsbrist. HR analytics ger en högre legitimitet för professionen vilket också pekar mot ett ökat framtida användande. HR analytics har också resulterat i ett större inflytande hos ledning och chefer. Slutsatser: Studien talar för en utbildningssatsning där fokuset inte enbart bör ligga på de `hårda ́ kompetenserna utan också på de `mjuka ́ såsom förändringsledning, storytelling och kommunikation.

The dissertation is focused on the current needs of the business effectiveness and efficiency in marketing activities. In an industrial environment is a prerequisite for the success of the strategic marketing objectives in relation to corporate strategy. In this work there is focus on individual performance systems and group of metrics that are currently applied in engineering in connection to the implemented marketing activities. The main aim of this dissertation is to propose a methodologyfor the selection of marketing metrics that are directly connected to the effectiveness of the company and its marketing activities in the field of engineering in the Czech Republic. To explore the knowledge area there was also used primary and secondary research. The primary research was conducted by structured interviews through case studies and knowledge-based questionnaire investigation, supported by evidence acquired Czech and foreign literary sources. The work includes detailed assessment of the empirical research, including the testing of hypotheses as basis on which is established the methodology for selecting marketing metrics in engineering in the Czech Republic. The benefits could be seen both in theoretical and practical as well as educational fields.

Circular economy (CE) is widely seen as a potential solution to negative impacts caused by thelinear economy; however, companies must integrate CE principles into the business modeldeeper to achieve sustainable development. The Product-Service System (PSS) businessmodel is a potential solution to the superficial implementation of CE due to shifting the focusto delivering functionality rather than ownership. However, several researchers point out thatPSS systems, whilst promoted as sustainability alternatives, rarely have enough quantitativedata supporting these outcomes and where the research field widely highlight the need tofurther develop assessment methods for PSS, with the use phase being a specifically criticalarea to monitor due to companies increased responsibility. This master’s thesis, therefore,aims to evaluate how companies monitor and assess their use-oriented PSS during the usephase to safeguard the intended increase in sustainability performance. To achieve theseobjectives, a qualitative, multiple case study was employed, where four companies wereinterviewed following a semi-structured approach, creating in-depth knowledge in each case. The case studies reveal that the different companies' primary methods to safeguard theirsustainability ambitions were through data collection, which, however, lacked the structuralsupport of Key Performance Indicators (KPIs). The different case studies could be seen tomainly collect performance data for proactive maintenance and consumer behaviour data toadjust their services and, by that, reduce environmental impact. However, only Volvo CarMobility did try to reduce the risk of unforeseen rebound effects by investigating customers'changed mobility behaviour. All of the companies did during the interviews refer to KPIs thatthey used to ensure that their sustainability goals were met; however, only one of the casestudies had an indicator that could meet the requirements of KPIs, whereas others lackedspecified targets, were vaguely defined or were irregularly collected. Additionally, the casestudies confirmed different strategic reasons for implementing their PSS other thansustainability and whether all sustainability goals could be connected to economic incentives.These different drivers confirm the PSS attraction and suitability for companies; however, italso emphasises the importance of implementing a system perspective to mitigate risks ofburden shifting and loss of the potential to contribute to sustainable development. Future research could further evaluate the importance of information and communicationtechnologies (ICT) when collecting data on PSS consumers, how AI-supported technologycould facilitate the recognition of consumer behaviour, and how this data collection shouldbe efficiently managed in the organisation. Additionally, another interesting avenue for futureinvestigation would be the overall consumer behaviour of society and its impact on businessmodels such as PSS. In conclusion, this master's thesis confirms and extends previous assertions on theimportance and complexity of use-oriented PSS and adds to the emerging literature on the subject through the information from the case studies. The findings also point to the holisticinsights and performance assessments required to optimise the potential and ensure thesustainability of the services. / Cirkulär ekonomi (CE) betraktas allmänt som en potentiell lösning på den negativa påverkansom den linjära ekonomin orsakar. För att uppnå en hållbar utveckling är det nödvändigt förföretag att djupare integrera CE-principer i affärsmodellen. Affärsmodellen förprodukttjänstsystem (product service system - PSS) anses vara en potentiell lösning när CEytligt implementerats i företag, detta genom att fokusera på att leverera funktionalitetsnarare än äganderätt. Dock pekar flera forskare på att PSS-system, trots att de främjas somhållbarhetsalternativ, sällan har tillräckligt med kvantitativ data som stödjer dessa resultat.Inom PSS forskningsfältet betonas behovet av att vidareutveckla bedömningsmetoder(Nakada et al., 2020), där användningsfasen anses vara ett specifikt kritiskt område attkontrollera på grund av företagens ökade ansvar. Denna masteravhandling syftar därför tillatt utvärdera hur företag kontrollerar och bedömer sina användningsorienterade PSS underanvändningsfasen för att säkerställa den avsedda ökningen i hållbarhetsprestanda. För attuppnå dessa mål användes en kvalitativ, flerfallstudie där fyra företag intervjuades med ettsemistrukturerat förhållningssätt, vilket skapade mer djupgående kunskap om vardera fall. Fallstudierna visar att de olika företagens huvudsakliga metod för att säkerställa sinahållbarhetsambitioner var genom datainsamling, men detta saknade dock det strukturellastödet av nyckeltal (Key Performance Indicators - KPI:er). De olika fallstudierna kunde sessamla prestandadata främst för proaktivt underhåll och konsumentbeteendedata för attjustera sina tjänster och därigenom minska miljöpåverkan. Endast Volvo Car Mobility försökteminska risken för oförutsedda rekyleffekter genom att undersöka kunders ändraderörelsebeteende. Samtliga företag hänvisade under intervjuerna till KPI:er som de användeför att säkerställa att deras hållbarhetsmål uppnåddes, men endast företaget som hyrde utbilbarnstolar hade en indikator som kunde uppfylla KPI-kraven, medan de andra fallensaknade specificerade objektiv, var vagt definierade eller insamlades oregelbundet.Dessutom bekräftade fallstudierna olika strategiska skäl för att implementera sina PSS utöverhållbarhet, och alla hållbarhetsmål kunde kopplas till ekonomiska incitament. Dessa olikadrivkrafter bekräftar PSS attraktion och lämplighet för företag, men betonar också vikten avatt implementera ett systemperspektiv för att minska riskerna för tunnelseende ochförskjutning av belastningen (s.k. burden shifting) och förlora potentialen att bidra till enhållbar utveckling. Framtida forskning kan rikta sig mot att ytterligare utvärdera betydelsen av informations- ochkommunikationsteknologier (Information and Communication Technology - ICT) vid insamlingav data om PSS-konsumenter, hur AI-stödd teknik kan underlätta igenkänning avkonsumentbeteende och särskilt hur denna datainsamling bör hanteras effektivt iorganisationen. Dessutom skulle en annan intressant väg för framtida undersökningar kunnavara samhällets övergripande konsumentbeteende och dess påverkan på affärsmodeller somPSS.   Sammanfattningsvis bekräftar denna masteravhandling tidigare påståenden omanvändningsorienterade PSS betydelse och komplexitet och bidrar till den växandelitteraturen om ämnet genom information från fallstudierna. Resultaten pekar också på deholistiska insikter och prestandabedömningar som krävs för att optimera potentialen ochsäkerställa tjänsternas hållbarhet.
