Bilgi Teknolojileri ve Üst Yönetim Desteğinin Tedarik Zinciri Performansına Etkisi: Türkiye İçin Ampirik Bir Yaklaşım

Bilgi ve iletişim teknolojisi uygulamaları şirketler için bir vazgeçilmez ve yüksek tedarik zinciri performansının kilit belirleyicileri haline gelmiştir. Tedarik zinciri uygulamalarının başarısının artması için, tedarik zinciri boyunca bilgi teknolojileri faaliyetlerinin uygulanması hayati öneme sahiptir. Bilgi teknolojilerinin ileri düzeyde kullanımı, kurum içinde bilgi akışının, işbirliğinin ve iletişimin artmasına ve böylece tedarik zinciri performansının yükselmesine yol açacaktır. Bununla birlikte, bilgi teknolojilerinin uygulanması ve kullanılmasıyla ilgili üst düzey yönetim desteği, kuruluşlar arası bilgi paylaşımının verimliliğini arttırmakta ve böylece tedarik zinciri performansı üzerinde olumlu bir etki yaratmaktadır. Çalışmada bilgi teknolojileri, iç entegrasyon, üst yönetim desteği ve bilgi paylaşımı arasındaki ilişkiler ve tedarik zinciri performansına etkileri değerlendirilmektedir. Bu değerlendirmede test edilen hipotezler, SPSS AMOS yazılımında Yapısal Eşitlik Modellemesi kullanılarak Türkiye'deki firmalarda çalışan personellerden toplanan verilerle analiz edilmektedir. Örneklem, çeşitli sektörlerde çalışan (imalat, tekstil, inşaat, gıda ve lojistik) üst ve orta düzey yöneticilerden, uzmanlardan ve uzman yardımcılarından oluşmaktadır. Öne sürülen yapısal model, 103 çalışandan toplanan verilerle analiz edilmiştir. Bilgi teknolojilerinin iç entegrasyon üzerinde olumlu ve önemli bir etkiye sahip olduğunu gösteren analiz sonuçları, iç entegrasyon ile tedarik zinciri performansı arasında benzer bir ilişki bulunmadığını göstermektedir. Ayrıca, üst yönetim desteğinin bilgi paylaşımını önemli ölçüde ve olumlu yönde etkilediği sonucuna varılmıştır. Buna ek olarak, bilgi paylaşımının tedarik zinciri performansı üzerinde olumlu bir etkisi vardır. Sonuç olarak, bu çalışma tedarik zinciri performanslarını geliştirmek isteyen firmalara rehberlik etmeyi amaçlamaktadır.

The Impact of Information Technologies and Top Management Support on Supply Chain Performance: An Empirical Approach for Turkey

Applications of information and communication technologies have become indispensable for companies, being key determinants ofhigh supply chain performance. Application of information technologies activities throughout the supply chain is vital for theincreased success of supply chain applications. Advanced utilization of information technologies will lead to an increased level ofinformation flow, cooperation and communication within the corporation, leading to integration and hence, a soaring up of supplychain performance. However, top management support regarding application and utilization of information technologies increases the efficiency of inter-organization information sharing, thus, creating a favourable impact over supply chain performance. This studyassesses the relations between information technologies, internal integration, top management support and information sharing andtheir effects on supply chain performance. Hypotheses tested in this assessment are analyzed through data collected from personalsworking for firms in Turkey, via utilizing the Structural Equation Modelling in SPSS AMOS software. The sample consists of seniorexecutives, mid-level managers, specialists and assistant specialists working in a span of sectors (manufacturing, textiles,construction, food and logistic). The structural model put forward is analyzed via data collected from 103 employees. Results ofanalyzing showing that information technologies has a positive and significant influence in internal integration whereas no similarrelationship is prevalent between internal integration and supply chain performance. Moreover, concludes that top managementsupport significantly and positively affects information sharing. In addition to this, information sharing has a positive effect on supplychain performance. All in all, this study aims to provide guidance for firms pursuing to develop their supply chain performance.
