Lean on a smaller scale : An insight into the goldsmith trade (English)
Abstract [sv]

Lean är ett arbetssätt som myntades av Toyota på 1950-talet och som vanligtvis är förknippat med stora tillverkande industriföretag. Den amerikanska universitetsprofessorn Jeffrey K. Liker sammanfattade leans arbetsmetodik med fjorton principer i den storsäljande boken The Toyota Way. I detta arbete undersöktes det hur applicerbara de fjorton principerna är på småskaliga tillverkningsföretag. Projektet avgränsades till småskaliga tillverkningsföretag inom guldsmedsbranschen med maximalt 10 anställda. Undersökningen påbörjades med en enkät som skickades ut till experter inom området lean, med avsikt att urskilja de principer som var mest tillämpbara för småskaliga tillverkningsföretag. Därifrån valdes principerna 3, 6, 7, 10, 12 och 14 ut som mest relevanta för småskaliga tillverkningsföretag. En litteraturstudie utfördes sedan för att hitta information om de utvalda principerna och som komplement till teorin intervjuades även en expert inom området lean. Tre guldsmeder i Stockholmsområdet intervjuades angående deras arbete medan arbetsstationerna och arbetsytorna inspekterades. Intervjuerna resulterade i hur guldsmederna arbetar i praktiken vilket kompletterade de teoretiska resonemangen kring lean och dess applicerbarhet i småskaliga tillverkningsföretag. Arbetet resulterade i slutsatsen att småskaliga tillverkningsföretag generellt arbetar med värderingar och ambitioner som påminner starkt om lean trots att ordet lean, och många andra beskrivande tekniska termer, inte var igenkännbara av guldsmederna själva. Ovannämnda principer kunde även framhävas och rekommenderas som intressanta för småskaliga tillverkningsföretag att förkovra sig i och applicera på sin verksamhet.

Abstract [en]

Lean is a working structure that was created initially by Toyota in the 1950s and is usually associated with large industrial manufacturing companies. The american university professor Jeffrey K. Liker summarized the lean work methodology with fourteen principles in the best-selling book The Toyota Way. In this paper it was investigated how applicable the fourteen principles are with respect to small-scale manufacturing companies. The project was limited to small-scale manufacturing companies with up to 10 employees within the goldsmith industry. The research began with a survey that got sent out to experts in the field of lean to discern the principles that were most applicable to small-scale manufacturing companies. Based on the survey the principles 3, 6, 7, 10, 12 and 14 were selected as most relevant to small scale manufacturing companies. A theory survey was then carried out to find information about the selected principles, and as a complement to the theory, an expert in the field of lean was also interviewed. Three goldsmiths based in Stockholm were interviewed regarding their work and at the same time the workstations and work surfaces were inspected. The interviews resulted in knowledge about how the goldsmiths worked in practice which strengthened the theoretical reasoning around lean and its applicability in small-scale manufacturing companies. The work resulted in the conclusion that small-scale manufacturing companies generally work with values and ambitions that strongly resemble lean even though the word lean, and many other descriptive technical terms, were not recognizable to the goldsmiths themselves. The above-mentioned principles could also be highlighted and recommended as interesting for small-scale manufacturing companies to engage in.
