The overall objective of this research is to support practitioners within the manufacturing industry to effectively design product-service system (PSS)-based solutions with relatively lower environmental impacts than typical product-centric solutions. Design research methodology (DRM) is applied to systematically address this objective with both descriptive and prescriptive approaches. The research draws empirical insights from a pool of 68 experienced product developers from the manufacturing industry. Initially, a generic model to predict the variant nature of domain-specific design cognition is conceptualized. Using this conceptual framework, differences in design cognition between conceptual product and PSS designing are theoretically predicted and empirically tested using protocol analysis. Based on a statistical comparison of the findings, the cognitive nature of PSS designing is descriptively characterized in relation to that of typical product designing. The results suggest that PSS designing is more problem-focused and applies a similar level of focus on the highest level of systems abstraction as product designing. A deeper investigation into PSS designing revealed that compared to product aspects, relatively less focus was afforded to the service aspects, interactions between product and service aspects, and the aspects regarding the overall PSS. Based on these findings, it was inferred that the cohort might need PSS domain-specific support to effectively design such systems. Three design support prescriptions were developed based on the improved understanding of the cognitive characteristics of PSS designing. One of these prescriptions, termed the PSS design schema, was developed using the method of literature analysis and synthesis. The other two prescriptions, termed lifecycle function deployment (LFD) and systemic lifecycle engineering, were developed using the method of action design research (ADR). Subsequently, the effects of the PSS design schema were descriptively tested using protocol analysis, and those of the other two prescriptions were assessed with a lifecycle assessment (LCA) of the design outcomes. The effects of the PSS design schema point towards significant changes in the cognitive characteristics of PSS designing. The effects of the other two prescriptions point towards significant reductions in the potential environmental impacts of the concepts when compared with the respective existing productcentric offerings that were redesigned using the support. Based on these empirical findings, the conceptual framework is refined and extended to conceptualize and hypothesize the interplays of pre-existing domain-specific knowledge of the designers and the effects of design support on design cognition.

520 $a Det overgripande malet med denna forskning ar att stodja utvecklare inom tillverkningsindustrin att effektivt skapa losningar baserat pa produkttjanstesystem (eng. product-service system (PSS)) som har en lagre miljopaverkan an typiska produktcentrerade losningar. For att uppfylla detta syfte tillampas en systematisk forskningsmetodik kallad DRM. Detta tillvagagangssatt mojliggor bade beskrivande och foreskrivande forskning. I forskningen nyttjas en resurs bestaende av 68 erfarna produktutvecklare fran tillverkningsindustrin for att uppna empiriska resultat. I ett forsta stadie utvecklas en generisk modell for att forutsaga karaktaren av domanspecifik designkognition. Genom att tillampa detta konceptuella ramverk forutsags och undersoks skillnader i designkognition vid utveckling av bade produkter och PSS. I ramverket anvands protokollanalys for att satta empiri mot teori. Sedan, baserat pa statistisk bearbetning och jamforelse av forskningsdata, beskrivs kognitiva kannetecken for PSS-utformning i forhallande till rutinmassig produktutveckling. Det indikeras att utformning av PSS-losningar ar mer problemfokuserat an for produkter. Daremot kraver bada lika stort fokus vid hog abstraktionsniva. Vid djupdykning inom PSS-utformning visas att begransat och inkonsekvent fokus tilldelas aspekter inom tjanster, interaktioner mellan produkter och tjanster samt overgripande for PSS. Baserat pa dessa resultat drogs slutsatsen att utvecklare kan behova domanspecifikt stod for att effektivt kunna utforma PSS. Med grund i den forbattrade forstaelsen av kognitiva kannetecken for PSS-utformning utvecklades tre metoder som stodjer under designstadiet. En av dessa, benamnd designschemat for PSS, utvecklades genom litteraturanalys och -syntes. De andra tva metoderna - driftsattning av livscykelfunktionalitet och systematisk livscykelteknik - utvecklades genom en aktionsforskningsmetod. Effekterna av designschemat for PSS undersoktes och beskrevs genom protokollanalys medan de andra tva evaluerades genom att tillampa livscykelanalys (LCA) pa det som utformats. De identifierade effekterna av designschemat for PSS pekar pa betydande forandringar i de kognitiva kannetecknen for PSS-utformning. Genom att anvanda det utvecklade stodet pekar de andra tva metoderna mot betydande minskning av konceptens potentiella miljopaverkan jamfort med respektive omarbetat produkterbjudande. Baserat pa de empiriska designkognitionsresultaten forfinades och utokades det konceptuella ramverket till att konceptualisera och hypotetisera samspelet mellan redan existerande domanspecifik kunskap hos utvecklare och effekten av stod vid utformning PSS-losningar.
