Abstract [en]

Key performance indicators (KPI) are used to monitor process performance, and to motivate and give clarity of priorities for employees. Although important, KPI:s may have drawbacks in the way that they represent the real performance. The purpose of this study is to develop the unit cost KPI. The new KPI discount for the volume influence on the KPI. Secondly, control charts tool found in statistical process control (SPC) theory is used to give indication to if the cost variation is within statistical control. The proposed method is validated on real data from 16 different cases in a major manufacturing enterprise. © 2020 The Authors. Published by Elsevier B.V.

Abstract [sv]

Utformandet av nya tillverkningssystem och fabriker är ett komplext arbete med många intressenter. I grund och botten är det en värdekedja som är i fokus, dvs tillverkningen av en lönsam produkt. Denna värdekedja styr utvecklingsprojekten och kraven som ställs på tillverkningssystemet kretsar runt kostnad, produktkvalitet och önskad tillverkningsvolym. Dessa krav fokuserar på den betalande kunden, vilket kan vara företagets viktigaste intressent. Utöver den betalande kunden finns det dock många andra intressenter som inte beaktas i någon större utsträckning vid kravställandet av nya tillverkningssystem. Enskilda goda exempel går att finna där exempelvis storskalig tillverkning av en produkt till lägsta kostnad inte är det primära målet. Fokus ligger i stället på andra värdekedjor som skapar mervärde för nya intressenter till tillverkningssystemet. Denna forskning har i avsikt att utforska vilka intressenter som finns till ett tillverkningssystem, och vilket mervärde som det går att leverera till dessa. Frågor som ställs är vilka externa intressenter som finns, vilka interna intressenter som finns, vilket mervärde kan tillverkningssystemet leverera till dessa och hur kan man beakta dessa i utvecklingsprojekten av nya tillverkningssystem? En mer utforskande samhällsvetenskaplig metod har använts, där inspiration tagits från etnografiska och kvalitativa metoder. De nio åren som doktorandprojektet pågått har en långvarig, djup datainsamling och analys möjliggjorts. Forskningen har resulterat i ett teoretiskt ramverk runt ett mer holistiskt synsätt på tillverkningssystemets värdekedjor. Den betalande kundens värdekedja kvarstår som primär, men kompletterats med nya externa och interna intressenter. Enskilda goda exempel har identifierats i olika industrier som används för att exemplifiera applicerbarheten i praktiken. Forskningen adresserar även utmaningar i att förändra dagens arbetssätt. Den starka kulturen på kundfokus samt beslutsprocesser som är ekonomiskt dominerande, är två aspekter som befäster dagens arbetssätt. Med ett mer strategiskt fokus, inkluderande kravställning samt ledningens öppenhet för en bredare beslutsgrund, skapas förutsättningar att utforma tillverkningssystem som skapar större mervärde för flera.

Abstract [en]

The design of new manufacturing systems is a complex process involving many stakeholders. The production of a profitable product is the value chain that steers the development projects, and requirements are specified around cost, product quality and the desired production volume. These requirements focus on the paying customer. In addition to the customer, there are, however, many other stakeholders who are not considered to any great extent. Individual good examples can be found where the large-scale production at the lowest cost is not the primary goal. Instead, the focus is on other value chains that create added value for new stakeholders related to the manufacturing system. This research intends to explore the stakeholders of a manufacturing system and the added value that can be delivered to them. There is a focus on understanding the current practices for manufacturing system development, how requirements are specified and how decisions are made. An explorative social science approach was applied, where inspiration was taken from ethnographic and qualitative methods. Nine years of (interrupted) industrial PhD studies have enabled a long[1]term and deep data collection and analysis. The research resulted in a theoretical framework built around a more holistic approach to the value chains of the manufacturing system. The paying customer’s value chain remains primary but has been supplemented with new secondary external and internal stakeholders, and related value chains. Individual good examples have been identified in the industry that are used to exemplify the applicability of the theoretical framework in practice. The research also addresses challenges in changing today’s way of working. A strong culture of customer focus and financially dominant decision-making processes are two aspects that consolidate today's way of working. With a more strategic focus, including holistic requirements and the management’s openness to a broader decision basis, the conditions are created for designing manufacturing systems that contribute with greater added value for more stakeholders
