Abstract [en]


To evaluate how lean production should be modified to be suitable for implementation in the production of digital, customized products and how the first phase of this implementation can be conducted.

Research Questions

RQ1: What constitutes waste when producing digital, customized products, and to what extent can the waste be eliminated?

RQ2: Which lean concepts and tools are suitable to apply in the production of digital, customized products?

RQ3: What steps are necessary for initial implementation of lean production for production of digital, customized products, and how should they be prioritized?


The empirical findings are the result of a single case study focused around in-depth analysis and understanding of concepts and relationships. The data is collected through interviews work shops and observations during a period of three months.


RQ1: The types of waste are; Waiting, Transportation, Over processing or incorrect processing, Excess inventory, Unnecessary efforts, Defects and Unused employee creativity. Waste are further classified as removable, non-removable and in some instances necessary.

RQ2: Unsuitable concepts: Value stream mapping (varying level of unsuitability), Kaikaku, Just in time, Stopping the

 line (without modifications) and Physical visual controls. Redundant concept: Pull. Especially suitable concepts: 5 Why, Decentralized responsibility, Digital visual controls and Isolating variation. Suitable concepts: Elimination of waste, Root cause analysis, Genchi genbutsu, Kaizen events, Flow, Stopping the line (with modifications) and Standardization.

RQ3: Step I: Aligning the production strategy and process with the organization’s strategy and goals. Step II: Standardization.

Abstract [sv]


Att utvärdera hur lean production bör modifieras för att vara lämpligt för implementering i produktion av digitala, kundanpassade produkter och hur den första fasen av implementationen bör genomföras.


F1: Vad utgör slöseri när man producerar digitala, kundanpassade produkter, och i vilken utsträckning kan slöseriet elimineras?

F2: Vilka lean-koncept och lean-verktyg är lämpliga att använda i produktion av digitala, kundanpassade produkter?

F3: Vilka steg är nödvändiga för initial implementation av lean production i produktion av digitala, kundanpassade produkter, och hur ska de prioriteras?


En fallstudie med fokus kring djupgående analyser och förståelse för koncept och samband utgör de empiriska resultaten. Datan är inhämtad genom intervjuer, work shops ochobservationer under tre månader.


F1: Typerna av slöseri är: väntetid, transport, onödiga eller felaktiga processteg, överproduktion, onödig ansträngning, defekter och outnyttjad kreativitet. Typerna av slöseri är vidare klassificerade som eliminerbara, icke eliminerbara eller i vissa fall nödvändiga.

F2: Olämpliga koncept: värdeflödesanalys, kaikaku, just in time, jidoka, fysisk visuell kontroll. Redundanta koncept: pull. Speciellt lämpliga koncept: 5 Why, decentraliserat ansvar, digital visuell kontroll och isolering av variation.

Lämpliga koncept: eliminering av slöseri, analys av rotorsaker, Genchi genbutsu, Kaizen event, Flöde, Jidoka (med modifikation) och Standardisering.

F3: Steg I: Strömlinjeforma produktionsstrategin med organisationens strategi och mål. Steg II: Standardisering.
