Amaç: Bu çalışma, işbirlikçi liderliğin kamu bankalarında çalışanların karar alma süreçlerine ilişkin algılarıyla olan ilişkisini ve bu ilişkide takım mükemmelliğinin aracı rolünü incelemektedir.Yöntem: Araştırma verileri, Türkiye’de faaliyet gösteren kamu bankalarında farklı örgütsel düzeylerde görev yapan 391 çalışan ve yöneticiden toplanmıştır. Tüm değişkenler bireysel algılar temelinde ölçülmüş ve analizler bireysel düzeyde gerçekleştirilmiştir. Geçerliliği kanıtlanmış ölçekler ve aracı değişken analizleri için Hayes’in PROCESS Makrosu (Model 4) kullanılmıştır.Bulgular: Bulgular, işbirlikçi liderliğin hem takım mükemmelliğiyle hem de çalışanların karar alma süreçlerine ilişkin algılarıyla pozitif ve anlamlı biçimde ilişkili olduğunu, ayrıca takım mükemmelliğinin, işbirlikçi liderlik ile karar alma süreçlerine ilişkin çalışan algıları arasındaki ilişkide aracı bir rol üstlendiğini ortaya koymaktadır.Özgün Değer: Çalışma, takım mükemmelliği kavramının sınırlarını ortaya koyarak bu kavramı geleneksel takım etkililiği ölçümlerinden ayrıştırmakta ve işbirlikçi liderliğin, yüksek düzeyde düzenlemeye tabi ve bürokratik bir kültürel bağlam olan Türk kamu bankacılığı ortamında nasıl işlediğini ampirik olarak açıklamaktadır. Uygulama açısından bulgular, işbirlikçi liderlik yaklaşımlarının çalışanların karar alma süreçlerine ilişkin algıları üzerindeki koşullu değerine işaret etmekte ve liderlik uygulamaları ile politika tasarımı için bağlama duyarlı öneriler sunmaktadır.

Purpose: This study aims to examine how team excellence mediates the relationship between collaborative leadership and employee perception in decision-making in Turkish public banks.Design/methodology/approach: This study employs survey data collected from 391 employees and managers across multiple organizational levels in Turkish public banks. All constructs were measured as individual perceptions and analyzed at the individual level. Using validated measurements and Hayes’ PROCESS Macro (Model 4), mediation analysis was conducted to test the indirect role of team excellence.Findings: The findings indicate that collaborative leadership is positively associated with both team excellence and employee perception in decision-making, and that team excellence mediates the association between collaborative leadership and employee perception in decision-making.Originality: This study contributes to the literature by illustrating the boundaries of team excellence, distinguishing it from traditional measures of team effectiveness, and empirically mapping how collaborative leadership is associated with the high regulatory and bureaucratic cultural domain of Turkish public banking, while offering context-sensitive implications for leadership practice and policy
