    A Method for Customer-driven Purchasing: Aligning Supplier interaction and Customer-driven manufacturing2012Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The role of a purchaser has traditionally focused on acquiring standard items at the lowest possible cost. The ability to reduce unit cost has been the key performance indicator for purchasers. Most traditional purchasing strategies thus focus on optimizing this situation, focusing on the supplier interface only and not on customer value. However, for many manufacturing companies, the demand from their customers has changed lately. Not only low‐cost standard products but also customized products and short delivery lead times is increasingly required. In order to contribute to the focal actor’s competitiveness, purchasers need a purchasing strategy that supports customer value creation and thus differentiates between acquiring standard items and acquiring customized items. Accordingly, not only the focal actor’s interaction with the supplier needs to be regarded in the purchasing situation, but also the interaction with the focal actor’s customer. This is defined as customer‐driven purchasing in this research.

    The purpose of this research is to develop knowledge that contributes to increased competitiveness of manufacturing companies. The manufacturer can increase competitiveness by further utilizing knowledge available in manufacturing strategy in the purchasing situation. The main objective of this dissertation is to analyze the competitiveness in customer‐driven purchasing and to develop a method for customerdriven purchasing by aligning supplier interaction with customer‐driven manufacturing. The method for customer‐driven purchasing (the CDP method) was developed in collaboration with Combitech AB, Ericsson AB, Fagerhult AB, Husqvarna AB, Parker Hannifin AB, and Siemens Turbomachinery AB. The CDP method consists of three phases, divided into twelve steps. The first phase focuses on identifying strategic lead times and differentiating between varying circumstances for the purchased items. The second phase focuses on analyzing customer‐driven manufacturing while the third phase focuses on analyzing supplier interaction. The method is concluded with the implementation of customer‐driven purchasing.

    When applying the three phases of the CDP method, the case companies have experienced a better alignment between customer expectations and supplier performance since the competitive priorities to pursue in a supplier interaction are identified and taken action upon. Direct visible results of implementing the model are, for example, shortened supply lead time for customized items, and reduced inventory levels for standard items. The CDP method has also helped the companies to identify critical suppliers and how the supplier interaction should be affected by the customer demand for the purchased item. Several indirect results have also been reported, such as, improved internal communication, and a better balance between short supply lead time and low cost. Thus the need to differentiate and balance the goals and key performance indicators for purchasers has become evident. Applying the CDP method has been seen as an important learning process in which the objectives of purchasing and manufacturing are aligned for improved competitiveness. This contributes to establishing purchasing as a strategically important competitive function and to support a holistic view of the focal actor’s competitiveness.

    Levels of Interaction in Supply Chain Relations2007Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    To be able to retain the manufacturing industry durably, in Europe in general and in Sweden in specific, manufacturing companies have to be competitive also on the global market. One way for companies to realize this ambition is to interact with suppliers and customers in different kinds of supply chains. In the dyadic relation between two companies, three different levels of interaction have been identified. To be able to enhance the competitiveness instead of requiring excess workload, the level of interaction has to be adequate for the specific company and their market conditions.

    The aim of this thesis is to clarify the characteristics of supply chain interaction, both in terms of different levels of interaction and concerning the factors affecting the appropriate level of interaction. A basic prerequisite to enable companies to select an appropriate level of interaction within their supply chain is also to clarify the present use of terminology.

    This research is conducted through theoretical studies. The theoretical findings are synthesized in order to fulfill the research objective.

    Characteristics of supply chain interaction in terms of affecting categories and factors are identified. The factors are sorted according to the category they support. An interaction framework that can be used to gain an overview over the categories and factors affecting the level of interaction in a specific situation is developed.

    The resulting interaction framework is aiming at industry applicability but is based only on theoretical studies (which in turn are based on empirical data).

    The aim is to support the interaction level decision for, primarily, small and medium sized manufacturing companies in order to increase their competitiveness.

    Despite the amount of research within the supply chain area, the question how companies should select the way to interact within their supply chain has so far been left unanswered. In this thesis, a number of categories and factors that affects the appropriate level of interaction are identified and listed.

    The lead time tree as a boundary object for developmental learning and improved conditions for purchasers2016In: 5th World P&OM Conference Proceedings, 2016Conference paper (Refereed)
    Abstract [en]

    Contradictions between individuals and different functions in organizations can serve asbasis for a constant challenge which, as it gets responded to and demand is fulfilled, canhelp people to develop and create viable organizations. (Argyris, 1990). Thesecontradictions, handled in an effective way drives, empowers and enables developmentin organizations. In order to get interdisciplinary functions to collaborate collectivelyboundary objects can be useful (Star and Griesemer, 1989). The purpose is toinvestigate if the lead time tree (Bäckstrand, 2012) can be used as a boundary object tosupport knowledge creation process across functional boundaries of purchasing,manufacturing, product development, sales etc.

    Guidelines for designing a purchasing process for small businesses2016Conference paper (Refereed)
    Abstract [en]

    The purpose with this paper is to contribute towards a deeper understanding of the purchasing process in SMEs. This is done by investigating general research regarding purchasing, business strategy and SMEs to create a framework of factors influencing purchasing processes in SMEs. The factors are then authenticated with an empirical study of an SME. It is concluded that all influencing factors from the framework can be applied to the SME, but that the SME tend to handle them with a short-term perspective. This paper will provide guidelines for SMEs in order to create purchasing processes with a long-term perspective, which is more integrated with their business strategy.

    Abstract [en]

    In recent years, many manufacturers have experienced an increased demand for customized products and services, which requires the manufacturer to simultaneously offer both standardized and customized products. Consequently, several manufacturing strategies must be efficiently employed. These companies do not express the same prerequisites as ‘pure’ ETO companies since they need to be able to differentiate customized orders from standard orders, but also be able to differentiate between the manufacturing dimension and the engineering dimension of customization. Whereas standard orders can be processed with a platform approach, the customized orders contain specific requirements and information represented by ‘customer-order specific information’ (COSI). This paper defines and presents competitive scenarios where platform constraints are combined with COSI for efficient customizations. Implications for the approach and a path forward is discussed.

    Investigating the Aspect of Interaction in the Mobile Manufacturing Concept2007In: NOFOMA 2007, 2007Conference paper (Refereed)
    Abstract [en]

    The aim of the mobile manufacturing concept is to provide solutions for mobile and flexible manufacturing capacity on demand. The idea with the concept is that a mobile manufacturing unit (MMU) could sent to the place where it is needed, either within the company, to a local supplier, to a customer, or to a partner, in order to, for example, cover a temporary volume peak.

    Within the research project Factory-in-a-Box, five fully operative MMUs have been designed and realized in close contact with Swedish manufacturing industries. The main logistic focus within the research project has been put on optimizing the transport solutions, while the implications on the relations in the supply chain have still not been analyzed. It is however, important to clarify that the geographical and organizational distance between the stationary site and the site where the MMU temporarily is located, affects the complexity of the information and material flow. In order to secure MMU productivity, both information and material flow to and from the stationary factory, the stationary factory’s sub-suppliers, the local suppliers, and the customer, must be handled.

    In order to use the MMU’s resources efficiently, the level of interaction with all these actors has to be selected wisely. Therefore, the aim of this paper is to investigate the information flow and material flow in one of the demonstrators within the Factory-in-a-Box project, in order to highlight the importance of selecting appropriate level of interaction and how mobility affects the supply chain relations.

    Abstract [sv]

    Syftet med detta papper är att undersöka hur graden av kundanpassning av ingående komponenter påverkar kostnad och ledtid. För att illustrera denna situation används ett exempel från hydraul pumptillverkaren Parker från när en ingående komponent ändrades från standard till kundunik utan att analysera hur detta påverkade ledtider och leveransförmåga. I pappret visar vi att KDI-metoden som simultant tar hänsyn till strategiska ledtider, grad av kundanpassning och kundorderns position ökar möjligheterna att ta väl underbyggda beslut, att undvika suboptimering och där igenom minska totalkostnaden.

    Abstract [en]

    The aim of this paper is to describe a conceptual alignment between the certainty-customization framework (Bäckstrand, 2012) and Kraljic’s purchasing matrix (Kraljic, 1983). This will enable companies that manufactures both standard and customer unique products to develop differentiated purchasing strategies for the constituent items based on the products competitive priorities and order winners. Through this distinction, different categories in the Kraljic-matrix needs to be handled differently based on the items position in regard to the customer-order-decoupling-point and its level of customization.

    Abstract [en]

    Olika aspekter på samverkan har rönt stor uppmärksamhet under de senaste årtiondena men har endast i begränsad omfattning integrerats med centrala produktions- och logistikstrategiska beslutskategorier. Ett område som till stor del varit frånvarande i forskningen om kund/leverantörssamverkan är kopplingen till olika grader av kundorderstyrning. Sedan länge har graden av kundorderstyrning ansetts som ytterst central i utformningen av strategier för produktions- och logistiksystem men har trots detta sällan inkluderats i olika modeller för val av grad av samverkan mellan företag. Denna brist på samordning av två så viktiga kunskapsdomäner innebär att avgörande pusselbitar troligen saknas i kunskapen om hur konkurrenskraftig industriell verksamhet bedrivs i samverkan. Dessa två perspektiv har stor påverkan på utformning av både produkter och logistiksystem. Om man dessutom beaktar den snabba förändringstakten på dagens marknader och den dynamik som då skapas så finns det mycket starka motiv för att säkerställa att rätt grad av samverkan med andra parter i försörjningsnätverket etableras för att kunna hantera de osäkerheter som finns om marknadens behov.

    Time-phasing and decoupling points as analytical tools for purchasing2013In: 2013 IEEE International Conference on Industrial Engineering and Engineering Management, IEEE, 2013Conference paper (Refereed)
    Abstract [en]

    Customization and customer-driven manufacturing are both explicitly based on end-customer relations and customer requirements. The impact of these aspects on internal operations is relatively well known and can be investigated using time phasing and decoupling points. These tools are however rarely used for analyzing purchased material. Based on the time phased product structure, items are categorized according to three criteria: driver, uniqueness, and make/buy. Purchased items can thus be identified using the last criteria and then driver and uniqueness are used as a point of departure for categorizing purchased material. The approach hence provides a platform for development of supplier relations based on the customer requirements which is the core theme of the method for customer-driven purchasing.

    Kundorderstyrning och kundanpassning - ett kund- och leverantörsperspektiv2012In: Plans Forsknings- och tillämpningskonferens 2012: Logistik i praktisk tillämpning / [ed] Peter Berling, 2012Conference paper (Other academic)
    Abstract [sv]

    Under forskningsprojektet KOPeration visade sig grad av kundanpassning vara en viktig egenskap att beakta vid utformningen av lämplig grad av samverkan i leverantörsrelationen. Projektet omfattar sex svenska tillverkande företag från olika branscher och är inriktat på kundorderstyrning och leverantörsrelationer.

    Projektet var inledningsvis inriktat på att undersöka i vilken utsträckning som kundorder är verksamhetsdrivande och hur det påverkar leverantörsrelationer. Under projektet visade det sig dock att ytterligare en komplicerande faktor i leverantörsrelationer identifierats, nämligen brist på överensstämmelse mellan det tillverkande företagets perspektiv och leverantörens perspektiv på grad av kundanpassning av en viss produkt. Inom ett företag finns en logisk sekvens av kundanpassningsgrad från standardartiklar, via kundunika artiklar till kundorderunika artiklar. Denna logiska sekvens gäller dock bara inom ett företag. En artikel som av leverantören uppfattas som kundunik kan ingå i standardsortimentet hos kunden, eller tvärt om, vilket kräver en mer nyanserad analys.

    Denna brist på överensstämmelse mellan kundens och leverantörens syn på kundanpassningsgrad är viktig att identifiera eftersom spekulationsrisken i försörjningskedjan då kan fördelas på ett bättre sätt. Det innebär en låg risk att tillverka och lagerhålla standardartiklar på spekulation (mot prognos, innan en kundorder har mottagits), medan tillverkning och lagerhållning av kundunika, eller till och med kundorderunika, produkter innebär en hög risk om det utförs på spekulation. Mycket talar därför för att den aktör som upplever den lägsta graden av kundanpassning bör lagerhålla produkter när det finns olika uppfattning av grad av unikhet.

    I detta papper definieras teorigapet gällande brist på överenstämmelse av kundens och leverantörens perspektiv på grad av kundanpassning. Därefter belyses det praktiska problemet, dvs. vikten av att identifiera situationer med ett ”ologiskt” flöde av kundanpassningsgrad. Potentiella fördelar med att vara medveten om dessa ”ologiska” flöden exemplifieras med hjälp av en fallstudie hos Parker Hannifin i Trollhättan.

    Abstract [sv]

    Allt fler företag upplever krav på kundanpassning av produkter men för att få nöjda kunder är en förutsättning att förstå vad kunder verkligen vill ha. Kundanpassade produkter förknippas ofta med små serier och kundernas beställningar innehåller olik information för varje order. För företag som erbjuder kundanpassningar kan kundkraven representeras av ”kundorderspecifik information” (KOSI) som inkluderar när, var och vad kunden vill ha. Att fånga dessa parametrar kan vara svårt då ordern ofta skiljer sig från andra. KOSI är inte bara svårt att fånga, när den kommuniceras eller överlämnas mellan individer, avdelningar eller olika informationssystem kan den lätt förvanskas, medvetet eller omedvetet, vilket kan liknas vid en visklek. När meddelandet nått den sista mottagaren är det ofta väsentligt annorlunda mot det som ursprungligen sändes. Dynamiken i denna process kan ses som ”kundorderspecifik kommunikation” (KOSK), dvs den kundorderspecifika informationens överföringsprocess. Syftet med pappret är således att skapa en konceptuell, teoretisk modell kring hur begreppen information och kommunikation förhåller sig till varandra i ETO-kontexter samt diskutera hur vidare forskning på området kan utformas.

    Getting the most out of a collaborative research project – Cross industry design for a holistic view and increased learning2018In: Proceedings of the 34th Annual ARCOM Conference, 3-5 September 2018, Belfast, UK / [ed] C. Gorse, & C. J. Neilson, Association of Researchers in Construction Management (ARCOM), 2018, p. 526-535Conference paper (Refereed)
    Abstract [en]

    Lately, collaborative research has gained recognition. The balance between scientific rigour and practical relevance is a continuing issue within construction management research. The purpose of this paper it to describe a cross-industry and cross disciplinary approach to co-creation of knowledge through a collaborative research approach. A collaborative research project on the topic communication regarding customer specific demands is presented using a model with two interacting cycles for knowledge creation. Two construction companies, a housing company with off-site manufacturing and a small subcontractor manufacturing street doors and front doors, are participating. Four other companies within mechanical manufacture, telecom and consultancy are involved. To engage the companies, the project emphasizes activities not adding any contribution to academic production. Networking, industrial education, publications in trade journals, participation in trade fairs etc. might be essential to convince the industry of the practical relevance. The findings prove that applied research does not need to be isolated to specific industries or disciplines, as the collected data are applicable to the different participating companies' despite of their differences.

    Co-creation of knowledge: Key aspects for relevance in collaborative research projects2016Conference paper (Refereed)
    Abstract [en]

    How can relevance for both industry and academia be achieved in collaborative research project? Despite the vast amount of literature on collaborative research, there is still a lack of empirically grounded studies on their practical use. We have investigated how the co-creation of knowledge was carried out in six collaborative projects, what was considered to be relevant results and what aspects that were found critical during the different phases of a collaborative research project. We found that joint activities during the initial phases, together with joint implementation of development initiates, was found most critical for relevance.

    The sign of lead time2016Conference paper (Refereed)
    Abstract [en]

    The aim of this paper is to investigate how the level of customization of constituent items affects cost and lead time. This is done by using one empirical illustrations, from the hydraulic pump manufacturer Parker, of when an item was offered customizable without considering the effect it had on the strategic lead times. It is concluded that the CDP-method that simultaneously regards strategic lead times, level of customization and the process driver of an item, increases the possibility to make informed decision and thereby lower the total cost by not sub-optimizing.

    Aligning operations strategy and purchasing strategy2011Conference paper (Refereed)
    Abstract [en]

    The possible advantages gained by outsourcing non-core competences and utilizing theglobalization of the market will be diminished if inter-firm relationships are notdesigned and managed properly. Hence, extended support for purchasing decisionsbased on market requirements in terms of order winners and delivery lead times isneeded. We provide a framework that combines the strategic implications from a wellknownpurchasing framework (Kraljic, 1983) with a decoupling based framework thatemphasizes the balance between efficiency and responsiveness, and the level ofcontrollability in the supply chain.

    Grad av kundorderstyrning2009In: PLANs forsknings- och tillämpningskonferens 2009: effektiva och lönsamma försörjningskedjor : artiklar från konferensen på Växjö universitet 19-20 augusti 2009, Stockholm: PLAN , 2009, p. 161-172Conference paper (Other academic)
    Abstract [en]

    Grad av kundorderstyrning är ett begrepp som används i många sammanhang men kanske inte alltid vilar på en så tydlig definition om vad som avses. Den vanligaste utgångspunkten är nog att utgå ifrån när en produkt blir knuten till en kundorder. Det här innebär att delar av materialflödet uppströms är prognosdrivna och de senare delarna, vars ledtid ligger inom leveransledtiden, är kundorderdrivna. Dessa två flöden sitter ihop i en lagerpunkt som fungerar som en buffert mellan flödena och den benämns ofta kundorderpunkt. Om man dessutom beaktar att man kan ha en stigande grad av säkerhet om kundordern längs flödet så kan flödet delas in i tre segment: spekulation, förväntan och åtagande, där den senare ligger efter kundorderpunkten. En annan aspekt är hur varianter skapas längs flödet. Detta är nära förknippat med utformningen av produktstrukturen och kan associeras med var i strukturen som dessa varianter skapas, d.v.s. variantspridningspunkten. Produktstrukturer kan inom ramen för detta ha olika uppbyggnad som t.ex. en specialprodukt som görs helt kundunik, eller en standardprodukt som ser likadan ut för alla kunder. Däremellan återfinns modulariserade strukturer som har inslag av standardmoduler,baserat på vilka man kan sätta samman kundunika lösningar. Sammanfattningsvis finns det tre olika grader av säkerhet om kundorder och några olika modeller för att hantera variantspridning. Detta innebär ett antal möjliga kombinationer, men enbart en delmängd av dessa är att betrakta som konkurrenskraftiga strategier. Syftet med den här artikeln är att belysa hur grad av kundorderstyrning kan definieras som ett koncept baserat på positionering av kundorderpunkt respektive positionering av variantspridningspunkt.

    Strategiska frikopplingspunkter och samverkan i försörjningskedjor2010In: PLANs Forsknings- och tillämpningskonferens 2010: Efterfrågedrivna försörjningskedjor / [ed] Sandor Ujvari, Stockholm: Logistikföreningen PLAN , 2010, p. 111-122Conference paper (Other academic)
    Abstract [sv]

    Ledning och styrning av försörjningskedjor kräver en god överblick över kedjornas grundläggande strukturella egenskaper och över hur samverkan mellan olika aktörer i kedjorna formeras. Fundamentala egenskaper ur detta perspektiv är hur verksamhetens processer är strukturerade och ur vilken utgångspunkt de är definierade. För att säkerställa att processer genomförs endast då ett behov är identifierat är det viktigt att fokusera på centrala processdrivare i flödet. Förutom att avgöra vad som initierar en process är det också viktigt hur, och av vilken aktör, processen planeras och styrs. Om en aktör har full kontroll över processen kan processen betecknas som styrbar ur den aktörens perspektiv men om den ligger utanför aktörens kontroll så kan den på motsvarande sätt beteckna som ostyrbar. Beroende på vilken aktör som styr en process och om samma eller en annan aktör genomför processen så skapas olika förutsättningar för utformning av hur dessa aktörer samverkar. Traditionellt har den typen av frågor, kopplat till leverantörssamverkan, behandlats inom inköpsstrategin. För att illustrera hur produktions- och inköpsstrategi kan knytas närmare varandra exemplifieras detta med hur den välkända Kraljic-modellen kan integreras i ett processbaserade ramverket med hjälp av fokus på ordervinnare.
