Abstract
Nowadays, the lean approach is accepted as a key for business operations. In recent years, Value Stream Mapping (VSM)
technique based on lean approach has emerged in the literature as a simple but
effective method to provide a holistic view to the state of the value stream in
a business. The objective of this study is to monitor how the non-value added
(waste) work steps can be removed and productivity growth can be achieved by
applying the VSM technique. For this purpose, after literature review, an
automotive firm is chosen with case study approach and a production process in
that firm is analysed in order to increase productivity with VSM technique.
Within the context of the production process, data is collected with focus
group method and observation. Following data analysis, value stream map both
for current and future situations are prepared in line with analysis results.
In case study, implementation processes are defined clearly and remarkable
efficiency gains in terms of cycle time and machine availability are achieved.
As a result, the study may contribute to conceptual framework in literature and
decision making process in production.

Abstract
Günümüzde yalın yaklaşım,
işletmeler açısından anahtar kabul edilmekte, son yıllarda alanyazında bu
yaklaşıma dayanan yöntemler içerisinde Değer Akışı Haritalandırma (DAH) Yönteminin
bir işletmedeki değer akışı koşullarına bütüncül bir bakış sağlamada sade ama
etkili bir yöntem olarak öne çıktığı tartışılmaktadır. Bu çalışmanın amacı, Vaka
Çalışması Yaklaşımı esas alınarak DAH Tekniğinin bir üretim prosesine
uygulanması ile israfların nasıl ortadan kaldırılabileceğini ve
iyileştirmelerle verimlilik artışı sağlanabileceğini incelemektir. Bu amacı
karşılayabilmek için ilgili alanyazın incelenerek, Vaka Çalışması Yaklaşımıyla seçilen
bir otomotiv firması ve dolasıyla bu firmanın bir fabrikasındaki bir parça
üretim prosesi ele alınmış ve DAH uygulaması ile bu prosesin verimliliği
arttırılmaya çalışılmıştır. Çalışmada, ele alınan üretim prosesi kapsamında; Belge,
Gözlem ve Odak Grup Görüşmesi yöntemlerinden yararlanılarak veri toplanmıştır.
Verilerin analiz edilmesi ile öncelikli olarak mevcut Değer Akış Haritası
çıkarılmış ve sonrasında analiz sonuçlarına dayanarak geliştirilen
iyileştirmelerle gelecek durum için Değer Akış Haritası tekrar çizilmiştir. Bu
süreçlerde, oluşturulan beyin fırtınası takımı ile birlikte çalışılmıştır.
Gerçekleştirilen uygulama ile özellikle çevrim zamanı ve makineler konusunda
önemli verimlilik artışları sağlanmıştır. Uygulama süreçleri mümkün olduğunca
ayrıntılı ve açık olarak tanımlanmaya çalışılmıştır. Dolayısıyla çalışmanın hem
kavramsal alanyazına hem de özellikle üretim sektörlerindeki karar alıcılara
katkı sağlayıcı ipuçları içeren bir niteliğe sahip olduğu söylenebilir.
