Abstract [en]

Vertical integration of supply chains has enabled industrialised house-building companies to develop and use product platforms. Constant changes in the external business environment, such as customer needs, legal requirements and demand fluctuations, continually compel companies to strategically align their product platforms with market position and offering accordingly. Achieving alignment is often hindered by a lack of understanding of the interplay between the external business environment, product platform, offering and market position. The knowledge on product platform alignment in this industry exists in the literature; however, a coherent description of product platform alignment is missing. The aim of this research was, therefore, to expand the knowledge on the strategic aspects of product platforms by describing product platform alignment in industrialised house building. Empirical data were collected in two Swedish companies producing timber-frame single-family houses. The developed model provides a coherent description of product platform alignment via five alignment modes that group interplays between product platform, business model and the external business environment, whereas identified challenges additionally enrich the description. Formalisation of the product platform knowledge and the changeability of manufacturing systems are identified as two main enablers of achieving product platform alignment.

Abstract [en]

Single-family industrialized house building is a trade characterized by a complete predefinition of products with off-the-shelf solutions offered to a market niche. Limited customization is included in the offerings in the form of a modular configuration of predefined components. A high level of prefabrication, often including volumetric elements, enables high efficiency in product variant realization processes, specifically, product specification, manufacturing, and on-site assembly. However, as the current markets are dynamic and often volatile, such offerings do not suffice in securing the success of business. Instead, offerings that include flexible product concepts with lower levels of predefinition and the concurrent achievement of high efficiency in processes using volumetric element prefabrication are needed. In this research, realizing this is characterized as the adoption of high-level mass customization.

The main value of the presented research for the practice is support for single-family industrialized house building in adopting high-level mass customization. The main enablers for the adoption of both lower and higher levels of mass customization are product platforms. The research on the development and use of product platforms has, however, been conducted mainly in multi-family industrialized house building. The differences in the types of offerings and customers between single-family and multi-family industrialized house building, reveal a research opportunity to study the development and use of product platforms in single-family industrialized house building. More specifically, the knowledge gaps include a lack of understanding regarding: the development and use of product platforms from a business model perspective, challenges for the development and use of product platforms when adopting high-level mass customization and support in addressing the identified challenges.

Therefore, the research purpose is to add to the knowledge on the development and use of product platforms and support that enables the adoption of high-level mass customization in single-family industrialized house building. The Design Research Methodology framework was used to plan and design the research. The research was conducted iteratively through four stages named: research clarification, descriptive study I, prescriptive study, and descriptive study II. The results provide an increased understanding regarding the development and use of product platforms in single-family industrialized house building through a coherent description of the product platform alignment phenomenon and the identified challenges when high-level mass customization is adopted. The results also increase knowledge regarding support in the development and use of product platforms that address the identified challenges. This part of the results is twofold. Firstly, an information modelling method is proposed, and it demonstrates how product platform use can be modelled in the design process of single-family industrialized house building. Secondly, the results demonstrate how the design module construct can be modelled using the design assets throughout the design process. To exemplify the design module construct, a configuration of the flexible volumetric elements and the panelized elements they are composed of is proposed. Process efficiency during the predefinition and modify-to-order specification of design modules is addressed. The presented research makes knowledge contributions to the theoretical fields of product platforms, building information management and business models.

Abstract [sv]

Villaindustrin är en branch som kännetecknas av fullständigt fördefinierade produkter med standard lösningar som erbjuds till en marknadsnisch. En begränsad anpassning ingår ofta i erbjudandena i form av en modulär konfiguration av fördefinierade komponenter. En hög prefabriceringsnivå, ofta bestående av volymelement, möjliggör hög effektivitet i produktvarianternas realiseringsprocesser, i synnerhet i produktspecifikation, tillverkning och montage på byggplats. Eftersom de nuvarande marknaderna är dynamiska och ofta volatila räcker emellertid inte sådana erbjudanden till för att säkerställa framgångsrika affärer. Istället behövs erbjudanden som inkluderar flexibla produktkoncept med lägre nivåer av fördefinition och som samtidigt uppnår en hög effektivitet i processer med användning av prefabricering av volymelement. I denna forskning kännetecknas denna realisering av användandet av höggradig mass-kundanspassning eller mass customization. Den industriella nyttan av den presenterade forskningen är att skapa stöd för villaindustrin att uppnå en höggradig mass customization.

De viktigaste möjliggörarna för att uppnå mass customization är produktplattformar. Forskning om utveckling och användning av produktplattformar har emellertid huvudsakligen bedrivits inom industriellt husbyggandet av flerfamiljshus. Skillnaderna i olika typer av erbjudanden och kunder mellan industriellt husbyggandet av flerfamiljshus och villaindustrin påvisar en forskningsmöjlighet att studera utvecklingen och användningen av produktplattformar inom villaindustrin. Mer specifikt inkluderar kunskapsgapen en brist för förståelse av: utveckling och användning av produktplattformar ur ett affärsmodellperspektiv, utmaningar för utveckling och användning av produktplattformar vid användning av höggradig mass customization och stöd för att hantera de identifierade utmaningarna.

Denna forskning syftar därför till att öka kunskapen om utveckling och användning av produktplattformar och stöd som möjliggör införandet av höggradig mass customization i villaindustrin. Design Research Methodology ramverket användes för att planera och designa forskningen. Forskningen genomfördes iterativt genom fyra stadier: (1) klargörande av forskningsuppgift, (2) beskrivande studie I, (3) föreskrivande studien och (4) beskrivande studie II. Resultaten ger en ökad förståelse för utveckling och användning av produktplattformar i villaindustrin genom en sammanhängande beskrivning av produktplattformens anpassningsfenomen och de identifierade utmaningarna som uppstår vid höggradig mass customization. Resultaten ger ökad kunskap om stöd vid utveckling och användning av produktplattformar som hanterar de identifierade utmaningarna. Denna del av resultaten omfattar två delar. För det första föreslås en metod för informationsmodellering som visar hur produktplattformanvändning kan modelleras i konstruktionsprocesser inom villaindustrin. För det andra visar resultaten hur design modul kan modelleras med hjälp av designtillgångarna under hela konstruktionsprocessen. För att exemplifiera ett design modul koncept föreslås en konfiguration av de flexibla volymelementen och de planelementen som de är sammansatta av. Processeffektivitet under produktfördefinition och modify-to-order produktspecifikation av designmoduler adresseras. Den presenterade forskningen ger kunskapsbidrag till de teoretiska områdena produktplattformar, BIM och affärsmodeller.
