A presente pesquisa procurou aperfeiçoar os conhecimentos no que se refere à gestão do desenvolvimento de novos produtos no segmento de componentes da indústria de materiais de construção. Não obstante a vasta literatura sobre a gestão do desenvolvimento de produtos, ainda existe uma lacuna no que diz respeito a este tema no setor. Procurou-se, então, identificar o grau de formalização, as etapas e as características da gestão do desenvolvimento de produtos na indústria de materiais de construção, como também as convergências e divergências entre os casos práticos e a literatura levantada. O desdobramento teórico desta pesquisa teve por base uma compilação dos principais modelos de gestão do processo de criação, como também do mapeamento do setor da indústria de materiais de construção. Por sua vez, o desenvolvimento empírico amparou-se na pesquisa qualitativa, predominantemente exploratória, baseada na técnica de estudo de casos múltiplos, contando com uma amostra de quatro empresas: Perflex, Deca, Cecrisa e Tigre. Verificou-se que existe um razoável nível de aderência entre o que preconiza a literatura e o que de fato acontece nas empresas pesquisadas, todavia, existem algumas contribuições relevantes que podem ser consideradas. Observou-se que nesse setor industrial os projetos derivativos são predominantes, com grande direcionamento para projetos topológicos; que o processo de captação de idéias realizado pela Cecrisa e pela Tigre diferenciase das demais empresas, obtendo as mais diferentes informações; que na etapa de desenvolvimento do conceito do produto a Cecrisa sobressai por inserir depoimentos de especialistas sobre a imagem da linha e a atualidade da idéia, o que poderá ser utilizado nas suas peças promocionais. Destaca-se, ainda, na montagem do produto, pois o faz em etapas iniciais, utilizando a matéria-prima e o processo produtivo finais. E a Deca, Cecrisa e Tigre realizam o lançamento interno do produto, distinguindo-se pela forma como é feito, e por não ter sido encontrado nenhum caso na literatura que inclua essa etapa no processo. É importante ressaltar a falta de aplicação de alguns critérios de Clark e Wheelwright (1993) nas empresas estudadas. Estas se diferenciam bastante das empresas utilizadas na pesquisa dos autores citados, pois são empresas pequenas com distâncias hierárquicas menores, onde acontecem constantemente reuniões formais e encontros informais para discussões e esclarecimentos sobre projetos. Com este estudo foi possível conhecer a realidade das indústrias de materiais de construção, a qual não se encontra em más condições, pelo contrário, está atualizada com os novos conceitos que envolvem o tema deste trabalho, gestão do desenvolvimento de novos produtos, com um processo e uma estrutura formal e organizada. / This study tries to improve the knowledge of the management of new products development in the industry of construction materials. Despite the vast literature on the management of the development of the products, there is still a gap in this subject related to the sector. For this reason, this study also tries to identify the degree of formalization, the phases and the characteristics of the management of the products in the industry of construction material, as well as the convergences and divergences between the practical cases and the literature studied. The empirical development of this research was based upon the compilation of the chief models of management of the process of creation, as well as the mapping of the sector of the industry of construction materials. In its turn, the empirical development had as its base a qualitative, prevailingly exploratory, research, based on the technique of study of multiple cases, counting on a sample of four companies: Perflex, Deca, Cecrisa and Tigre. It was verified that there is a reasonable degree of disparity between what the relevant literature states and what it is done in the target companies; nevertheless, there are some excellent contributions that can be taken into consideration. It was noticed that in this industrial sector derivative projects prevail, many oriented to topological projects; that the process of capture of ideas and information carried out by Cecrisa and by Tigre is different from that of the other companies, getting the most varied information; that in the face of the conceptual development of the product Cecrisa stands out for inserting testimonials of experts on the image of the line and the up-dated character of the idea, which may be used in the advertising pieces. It also stands out in the assembling of the products for doing it in the initial phases using raw material and the final productive process. Deca, Cecrisa and Tigre make the internal launching of the product, differing from others by the form of doing it, and for the effect that no similar case has been found in the relevant literature that includes this phase into the process. It is important to note the lack of application of some of Clark and Wheelwright\'s principles (1993) in the companies studied. This target companies differ largely from the companies used in the research of the authors mentioned, for they are small companies with smaller hierarchical distances, where formal and informal meetings taken place, constantly, for discussions and clarifications about projects. With this study it was possible to learn about the reality of the construction materials industries, which, by the way, is not badly off; on the contrary, it is up to date with the new concepts of the theme of this study, the management of new products development, with a process and a formal and organized structure.

O Processo de Desenvolvimento de Produtos (PDP) é considerado a essência da criação de novo conhecimento na empresa. Os investimentos e esforços em gestão que visam à melhoria da capacidade criativa, da tomada de decisão e do emprego de melhores práticas, tendem a elevar o nível de competência dos recursos humanos, intervindo, conseqüentemente, no resultado final do produto. Esta dissertação apresenta um modelo conceitual de integração de ferramentas de auxílio ao PDP com aplicação no setor alimentício, com vistas a enfatizar a utilização destas de maneira associada, considerando alguns princípios da Gestão do Conhecimento (GC). Este modelo foi construído utilizando a estrutura base de um modelo referencial de PDP para a indústria de alimentos. Para a alocação no modelo proposto, algumas ferramentas foram selecionadas na literatura para o setor e, posteriormente, foram analisadas sob a ótica da criação do conhecimento. A relação existente nesta dissertação entre o PDP e a GC é relevante para elucidar a importância de criar, utilizar, compartilhar e registrar o conhecimento que faz parte da memória organizacional e que, normalmente, existe dentro da empresa de forma não estruturada. Neste contexto, as ferramentas de auxílio ao PDP podem servir como conversoras do conhecimento, transformando-o de tácito para explícito, e reciprocamente. Após o desenvolvimento do modelo, o mesmo foi validado junto à gerência do setor de P&D de uma empresa, comprovando-se a sua exeqüibilidade e facilidade de aplicação e benefícios associados ao PDP. Também foi possível comprovar a existência da relação entre a exeqüibilidade do modelo, o nível de maturidade da empresa e o investimento em capacitação. / The Product Development Process (PDP) is the essence of new knowledge creation in any industry. There is no doubt that the human resources’ abilities and expertise are improved by investments and efforts towards projects that bring higher levels of creative capacity, decision making support and better procedures implementation support. And it’s clear that improving the human resources’ level of competence interferes in the final product result. The present dissertation shows a tool integration conceptual model that assists PDP especially in the food industry. One of the main ideas is to emphasize the tool’s application in an associated manner, considering some Knowledge Management (KM) principles. This model was built based on a PDP’s referential model for the food industry. Some tools were selected from the food industry’s literature in order to allocate the tools in the proposed model. After, the tools were analyzed with a knowledge creation point of view. The relation between PDP and KM showed in this dissertation is important to explain the relevance of creating, using, sharing and registering the knowledge, which is a corporate memory’s part that usually exists in the industry in a non-structured way. In this context, the PDP’s tools are able to convert the knowledge, turning it from tacit into explicit and reciprocally. The Research and Development Department’s manager of a confidential company validated the proposed model. According to the interviewing results, it was considered that the model is executable, easy to apply and its use brings advantages to the PDP. Also, it was evident that there is a relation among the model’s application, the company’s maturity phase and the investments in the employee’s capabilities.

Este trabalho apresenta um modelo de referência para o processo de desenvolvimento de produtos no setor moageiro de trigo. O modelo tem a finalidade de facilitar os projetos de novos produtos, avaliando a necessidade, requisitos e limitações do setor; de modo a contribuir para melhores resultados em custos, qualidade e tempo de desenvolvimento, integração entre as áreas funcionais e transferência de informações. O modelo de referência proposto foi elaborado a partir de conhecimentos adquiridos da literatura de desenvolvimento de produto, diagnóstico do ambiente interno e externo do setor moageiro, estudo sobre duas empresas moageiras de médio porte e seus fornecedores. A modelagem é orientada por sete diretrizes, que visam definir as práticas de gestão para conduzir o processo de desenvolvimento de produtos (PDP) aos objetivos esperados e as particularidades desejadas. A estrutura operacional do modelo é composta por três macro-fases e oito fases, abrangendo desde o planejamento do portfólio de produtos até a retirada do produto do mercado. Estas fases são desmembradas em atividades e tarefas, onde ferramentas de apoio ao modelo podem ser utilizadas para gerar as informações de saídas necessárias para o avanço do projeto. No término de cada fase, as principais informações são compiladas em forma de um documento, que deve passar pela avaliação da direção (gate). A direção determina entre: continuar, descontinuar o projeto ou revisar a fase. A aplicação do modelo de referência foi realizada a partir de um plano para sistematizar o PDP de uma das empresas estudadas. A intervenção para adaptar o modelo de referência à empresa apresentou as etapas de: analisar a situação atual do PDP, propor melhorias e conduzir a aplicação do modelo. Entre os principais resultados, destaca-se a facilidade de enquadrar as soluções propostas para melhorar o PDP da empresa ao modelo referencial. Mostrando, assim, que o modelo de referência é exeqüível e de fácil adaptação as especificidades das empresas da indústria moageira. Também foi possível conferir, que o modelo está alicerçado na metodologia do desenvolvimento integrado de produtos, onde o banco de dados integrado permite a troca de informações e o aprendizado no processo de desenvolvimento, proporcionando o amadurecimento da estrutura organizacional. / This work presents a reference model for the milling wheat product development process. The model targets to facilitate the project of new products, evaluating the necessity, requirements and limitations of the sector. It contributes for better results in costs, quality, development time, integration among functional areas, and proper information transfer. The reference model proposed was elaborated from knowledge acquired in product development literature research, diagnosis from the internal and external milling industry environment, study about two medium size milling company and a questionnaire filed up by their suppliers. The model is oriented from seven policies, which aim to define managing practices to conduce the products development process (PDP) through the expected goals and the desired particularities. The operational structure of the model is composed by three macro-phases and eight phases, enclosing from product portfolio planning to the end of product life in the market. These phases are divided in activities and tasks, where model's support tools can be used to generate the output information necessary to the advance of the project. At the end of each phase, the main information is compiled in form of a document, which must pass by a top management evaluation gate. Top management decides between: continuing, discontinuing the project, or review the phase. The reference model application was planned to systemize milling wheat companies' PDP. The intervention to adapt the reference model to the company presented the following stages: analyse the actual status of the PDP, propose improvements, and conduct model application. Among the main results, stand out the facility to apply the proposed solutions to improve the company's PDP using the reference model. Showing that the reference model is easy to adapt and implement in milling wheat companies. It was also possible to figure out that the model is founded in the integrated product development methodology, where the integrated data base allow information and know-how transfer during the development process, proportioning improvement of the organization structure.

Purpose – The purpose of the research is to increase the understanding of how insufficient information sharing between internal stakeholders can be mitigated during new product development projects. Two research questions were formulated to conduct answers to the purpose.  Why is it crucial to mitigate insufficient information sharing between internal stakeholders during new product development projects? How can potential challenges during new product development projects be mitigated through information sharing between internal stakeholders? Method – To create an understanding of information sharing a literature review was conducted, which formed the foundation of the theoretical framework. Through a case study at SAAB Training & Simulation, interviews were used as the main source for empirical data. Document studies and observations were used to triangulate the findings. The collected data and theoretical framework were analyzed and discussed to propose improvements. Findings – The research findings indicate that an insufficient information flow can cause several challenges related to deadlines, profit and how information is interpreted. It should therefore be a prioritization for an organization to constantly improve how information is shared between internal stakeholders during new product development projects. Additionally, the research analysis suggests that organizations’ need to allocate more time for educational opportunities. Implications – The research highlighted a new perspective on previous research within the area. Through the research analysis statements and theories made by other researchers were further strengthened. The research suggests ways of improving information sharing between internal stakeholders. The result can be used by other industrial organizations working with new product development projects to improve their information sharing to mitigate challenges connected to insufficient information sharing. Limitations – Due to the complexity of information sharing within new product development projects, the research was limited to one case company. Additionally, mainly managers were interviewed which posed a risk that the collected data only provided an overview rather than a deep insight in the processes of sharing information between internal stakeholders. If the authors were to use several organizations and conduct more interviews, the results could increase the credibility and generalizability of the research.

Lean Product Development is a knowledge-based business concept in order to maintain high quality, meetcustomer requirements and to make product development more efficient. An important part of the processis to add a lot of resources at an early stage and execute the development as an iterative process betweendepartments exploring many alternatives thoroughly. The work focuses on how Lean ProductDevelopment is carried out and explores how to manage interaction between different departments andexpertise with regard to cross-functional collaboration and knowledge sharing i.e. learning.The information for the studies was gathered at a major Swedish company from two projects. The projectswere carried out as cross-functional and possible key factors for cross-functional collaboration wasidentified.The results have been correlated with theories of Lean, Product development, Lean product developmentand Learning. The analysis shows that to carry out activities according to Lean product development willrequire more than to follow the concept’s framework for successful implementation. Factors that areidentified as important in cross-functional collaboration is also recognised in the Lean productdevelopment theory. However the theory does not indicate how the factors is implemented and carried outbut how it should be implemented. This will create opportunities and problems for companies that want towork and implement Lean product development.

Lesjöfors Fjädrar AB is a spring manufacturing company. At the start of each manufacturing process when manufacturing cold coiled compression springs, the operators manually feed the spring wire from a reel that contains the raw spring wire, into the machine where the springs are made. This is a demanding process for the operators. The largest diameter of the spring wire today is 18 mm. Lesjöfors Fjädrar AB wants to increase the diameter to 22 mm and needs a new construction that allows feeding coarser spring wire from the reel into the machine. Trips were made to the factory in Lesjöfors where interviews and observations were made. A survey was conducted to gather information about the current process, as well as ideas for a new construction. With the information gathered, a requirement specification was made and approved by Lesjöfors Fjädrar AB. A brainstorming meeting was held at Rejlers Sverige AB in Karlstad with experienced constructors. The concepts generated during the meeting together with concepts generated alone were combined and evaluated using eliminations matrices and relative decision matrices. The highest ranked concept secures the spring wire with a hook inside the reel and extracts the spring wire with the help of a lift system. The lift system consists of a ball screw and an electric motor. After extraction, the spring wire is secured by two rollers before it is fed towards the machine by the electric motor currently installed on the reel. Along the way to the machine, the spring wire is steered/aligned by two pipes. The final concept was modeled in Autodesk Inventor Professional 2018 where the concept was designed in more detail. A stress analysis was conducted as a final step in the design phase. The final construction withstands the forces from the spring wire and makes it possible for Lesjöfors Fjädrar AB to start manufacturing cold coiled compression springs with a diameter of 22 mm, following the new working sequence made in this project. / Lesjöfors Fjädrar AB är ett företag som tillverkar fjädrar. I början av tillverkningsprocessen av kallformade tryckfjädrar matar maskinoperatören fjädertråden manuellt från en haspel in i maskinen där fjädrarna tillverkas. Detta är ett påfrestande arbete för maskinoperatörerna. Den grövsta tråden som används idag är 18 mm i diameter. Lesjöfors Fjädrar AB vill öka diametern till 22 mm och behöver en ny konstruktion som gör det möjligt att mata den grövre fjädertråden till maskinen. Besök gjordes på fabriken i Lesjöfors där intervjuer och observationer gjordes. En enkät skapades för att samla information om den nuvarande processen samt idéer gällande den nya konstruktionen. Med den insamlade informationen skapades en kravspecifikation som godkändes av Lesjöfors Fjädrar AB. Ett konceptgenereringsmöte hölls på Rejlers Sverige AB i Karlstad med erfarna konstruktörer. Koncepten som genererades under mötet samt koncept som genererades enskilt kombinerades och utvärderades med hjälp av elimineringsmatriser och relativa beslutsmatriser. Det högst rankade konceptet säkrar fjädertråden med en krok inuti haspeln och lyfter den med hjälp av ett hissystem. Hissystemet består av en kulskruv och en elmotor. När fjädertråden är ute ur haspeln säkras den med två rullar innan den matas till maskinen av den nuvarande installerade elmotorn på haspeln. På vägen mot maskinen styrs fjädertråden rätt med två rör. Det slutgiltliga konceptet modellerades i Autodesk Inventor Professional 2018 där det konstruerades i detalj. En spänningsanalys gjordes som ett sista steg i konstrueringsfasen. Det slutgiltliga konceptet klarar av kraften från fjädertråden och gör det möjligt för Lesjöfors Fjädrar AB att börja tillverka kallformade tryckfjädrar med 22 mm i diameter när de följer den nya arbetsmetoden skapat i detta projekt.

This Thesis has been carried out as a final part of the Mechanical Engineering programme (180 credits) at Karlstad University during the spring semester 2022 and comprises 22.5 credits. The work is carried out on behalf of Valmet AB in Karlstad.At the beginning of a tissue machine, a mixture of fibres and water is fed into the machine and formed into a sheet using a forming wire and felt. During maintenance work, the wire sometimes needs to be detached from the machine. In order to release the forming wire, the breast roll retraction system needs to be opened up, which is done using an arm with the breast roll attached to it. This arm can rotate upwards, taking the breast roll with it, and when this is opened, the forming wire can be removed. In the hinge that this arm is attached to there is a gap, in addition to the gap the arm can be bent slightly. When the arm is returned to its original position after replacing of the forming wire, this gap and bending creates some problems. The problem is that the arm needs to return to its original position with great precision to avoid unnecessary adjustments. This is currently done using keys with angled walls and to lock the position eye bolts with associated nuts. The manufacturing of this solution has been identified as expensive due to tight tolerances and the angled walls of the keys and keyways. The aim of this project is to make the design cheaper to manufacture through design modification of this positioning and locking mechanism.Through a feasibility study regarding the current design and manufacturing method a deeper understanding of the function and machining was gained. The project has followed a structured product development process, from pre-study through requirements specification, concept generation and evaluation to detailed design. A requirement specification was developed using the results of the feasibility study together with information from Valmet employees. Two concept generation sessions were conducted, the 6-3-5 method and morphological matrix, these were done together with people at Valmet with different experiences. For concept evaluation and selection, Harris profile and relative decision matrix were used, these were conducted after consultation with experienced people at Valmet.The best concept is a design change that eliminates the milled angled walls in the keyway on the arm. These are replaced by a cylindrical pocket and a threaded hole. A corresponding change is made to the bracket against which the arm rests. Instead of the keys used today, two turned parts with a conical contact surface between them are proposed. This solution achieves all the requirements of the requirements specification as well as all the wishes except that it should fit similar fastening elements in other sections of the machine. The explanation for this is that the other fastening elements have slightly different functions which the proposed solution does not take into account. The price difference between the current design and the design proposed by the project has been obtained by a subcontractor providing price proposals for both. / Detta Examensarbete har genomförts som en avslutande del av maskiningenjörsutbildningen (180 hp) vid Karlstads universitet under vårterminen 2022 och omfattar 22.5 hp. Arbetet utförs på uppdrag av Valmet AB i Karlstad. I början av en tissuemaskin förs en blandning av fibrer och vatten in i maskinen och formas till ett ark med hjälp av en vira och filt. Vid underhållsarbete behöver viran ibland tas ut från maskinen. För att lossa viran behöver bröstvalsen öppnas upp, detta görs genom att bröstvalsen sitter fastspänd på en arm. Denna arm kan rotera upp och tar då med sig bröstvalsen, när denna är öppnad så kan viran tas ut. I gångjärnet som denna arm sitter på finns ett glapp, förutom glappet kan armen böjas något. När armen, efter att viran bytts ut, ska återgå till sitt ursprungliga läge skapar detta glapp och böjning viss problematik. Problemet är att armen behöver återgå till sitt ursprungliga läge med stor precision för att undvika onödiga justeringar. Detta görs idag med hjälp av kilar med vinklade väggar samt för att låsa fast positionen fäll skruvar med tillhörande mutter. Tillverkningen av denna lösning har identifierats som dyr på grund av snäva toleranser och de vinklade väggarna på kilen och kilspåret. Syftet med detta projekt är att genom designändring av denna positionering och låsningsmekanism få konstruktionen billigare att tillverka. Genom en förstudie gällande den nuvarande designen och tillverkningsmetoden skapades en djupare förståelse av funktion och bearbetning. Projektet har följt en strukturerad produktutvecklingsprocess, från förstudie genom kravspecifikation, koncept -generering och -utvärdering till detaljkonstruktion. En kravspecifikation togs fram med hjälp av resultatet från förstudien tillsammans med information från anställda på Valmet. Två konceptgenereringssessioner genomfördes, 6-3-5 metoden och morfologisk matris, dessa gjordes tillsammans med personer på Valmet med olika erfarenheter. För konceptutvärdering och val användes Harris profile samt relativ beslutsmatris, dessa genomfördes efter konsultation med erfarna på Valmet. Det bästa konceptet är en konstruktionsändring som eliminerar de frästa vinklade väggarna i kilspåret på armen. Dessa ersätts av en cylindrisk ficka samt ett gängat hål. Motsvarande ändring görs på konsolen som armen ligger mot. Istället för de kilar som används idag föreslås två svarvade parter med konisk kontaktyta mellan varandra. Denna lösning uppnår alla krav i kravspecifikationen samt alla önskemål förutom att den ska passa liknande förband i andra delar av maskinen. Förklaringen till det är att de andra förbanden har något annorlunda funktion som den föreslagna lösningen inte tar hänsyn till. Prisskillnaden mellan den nuvarande och den av projektet föreslagna designen har tagits fram genom att en underleverantör lämnat prisförslag på båda.

I samarbete med Kungliga Tekniska Högskolan har uppdragsgivaren ÖMV AB utformat ett uppdrag som berör en av deras tidigare huvudprodukter, fiberfiltret. ÖMV AB ingår i OSTP Group Company. Genom engagemang och modern teknologi konstruerar, tillverkar och utvecklar ÖMV AB avancerad process utrustning som bidrar till en hållbar framtid. Företagets huvudprodukter är reaktorer, värmeväxlare, cisterner, tankar. Planer om att återuppta tillverkningen av fiberfiltret som är en av företagets tidigare produkter är aktuell, men det tidigare konceptet bör ses över och utvecklas för att uppfylla kundens önskemål. Det nuvarande konceptet anses innehålla brister och områden som potentiellt behöver förbättras, utvecklingen kommer att utföras med hänsyn till både konstruktion och även hur produkten anpassas för användarens säkerhet. Dagens fiberfilter används inom papper- och massaindustrin, dess syfte är att separera massa till fibrer och vatten för att förhindra fibrerna från att släppas ut i vattendrag. Målet med detta arbete är att ta fram minst tre alternativa lösningar för en förbättrad stödkonstruktion, även utveckla fiberfiltrets luckor som i nuläget anses utsätta användaren för risker, minst två koncept ska tas fram som uppfyller maskindirektivets föreskrifter. Utvecklingen av fiberfiltret kommer ske med hjälp av ett antal systematiska produktutvecklingsmetoder, de olika lösningarna kommer att analyseras och modelleras i ett datorstött designverktyg kallat Creo PTC. / In collaboration with the Royal Institute of Technology, the commissioner ÖMV AB has designed an assignment relating to one of their former main products, the fiber filter. ÖMV AB is part of OSTP Group Company. Through commitment and modern technology, ÖMV AB designs, manufactures and develops advanced process equipment that contributes to a sustainable future. The company's main products are reactors, heat exchangers, cisterns and tanks. Plans to resume fiber filter manufacturing as one of the company's previous products are current, but the previous concept should be reviewed and developed to meet the customer's wishes. The current concept is considered to contain shortcomings and there are areas that may need to be improved, development will be carried out with regard to both design and also how the product is adapted for user safety. Today's fiber filters are used in the paper and pulp industry, its purpose is to separate pulp into fibers and water to prevent the fibers from being released into watercourses. The aim of this work is to develop at least three alternative manufacturing methods for an improved support structure, including developing the fiber filter gaps that are currently considered to expose the user to risks, at least two concepts must be developed that comply with the Machinery Directive. The development of fiber filters will be done using a number of systematic product development methods, the different solutions will be analyzed and modeled in a computer-aided design tool called Creo.

I dagsläget är det svårt för företag att behålla en stark marknadsposition och utmaningen ligger dels i att regelbundet presentera nya produkter på marknaden och ständigt skapa nya innovationer. Genom att använda sig av Lean Product Development i produktutvecklingsprocessen kan företagen anta utmaningen. Det kan dock vara svårare för små och medelstora företag då de kan ha begränsade resurser. Syftet med denna studie var därför att ta fram en projektmodell för produktutvecklingsprojekt i små och medelstora företag. Studien bygger på kvalitativa forskningsmetoder där sekundärdata samlades in genom både bibliotekskatalogen vid Mittuniversitetet och sökningar i forskningsdatabaser på Internet. Därefter samlades primärdata in via intervjuer för att göra en fallstudie och ett teoretiskt applicerbarhetstest. Resultatet som genererades visade att det som karakteriserar produktutvecklingen i små och medelstora företag var främst att chefen eller ägaren ofta påverkar produktutvecklingen och nyckelfaktorerna för en framgångsrik produktutveckling är processer, resurser, strategier och en god kommunikation. Den slutgiltiga projektmodellen baseras i stora drag på den generella projektmodellen och genomgick inga större förändringar efter det att det teoretiska applicerbarhetstestet hade genomförts. Projektmodellen består av fem stycken faser: förstudie, planering, genomförande, avslut och effekthemtagning. Samtliga presenterade projektmodeller skulle kunna fungera för att skapa processer, resurser, strategier och en god kommunikation. De nämnda projektmodellerna skiljer sig något i utformning och fokuserar på olika saker. Det som skiljer projektmodellerna åt är både roller och ansvarsbeskrivningar, beslutspunkter samt projektmodellernas olika faser. Det nyhetsvärde som denna studie har bidragit med är hur små och medelstora företag kan arbeta med projekt inom produktutveckling, och en fråga som har väckts är hur denna projektmodell skulle kunna se ut för att främja hela organisationen och inte endast produktutvecklingsavdelningen. / Today it is hard for companies to keep a strong market position and one part of the challenge is to regularly present new products on the market and constantly create new innovations.  The companies can accept that challenge by using Lean Product Development in the product development process. It can however be more difficult for small and medium sized enterprises as they may have limited resources. The purpose with this study was therefore to develop a project model for product development in small and medium sized enterprises. The study was built on qualitative research methodologies, first secondary data was collected through both the Mid Sweden University’s library catalog and searches in research databases on the Internet. Then, the primary data was collected through interviews to create a case study and a theoretical applicability test. The generated result showed that it characterizes the product development in small and medium sized enterprises primarily was that the manager or owner often affect the product development and the key factors for a successful product development was processes, resources, strategies and a good communication. The final project model are in general based on the general project model and did not underwent any major changes after the theoretical applicability test had been carried out. The project model consists of five phases: feasibility study, planning, implementation, closing and effect transfer. All of the presented project models could work to create processes, resources, strategies and a good communication. The mention project models differ slightly in the design and they are focusing on different areas. The differences in the models are the roles and responsibilities descriptions, decision points and the models different phases. The newsworthy this study has contribute with is how small and medium sized enterprises can work on projects in product, and one question that has been raised is how this project model could look like to promote the whole organization not only the product development departure.
