Abstract

Usability is considered an important issue that ensures successful product design and use. Today, usability is of critical subject for smartphones that enable users to perform many tasks with software and hardware aspects. In this study, a conceptual usability evaluation model including design, customer focus, quality, innovation, usability, and user perception variables is proposed considering the expectations of smartphone users. The reliability and validity of the proposed model were tested using the structural equation model (SEM) with survey data collected from 417 smartphone users. The findings and results lead smartphone designers and marketing professionals to identify users' needs for smartphone usability. Moreover, this study provides users with strategic information in observing critical aspects of smartphones based on the index scores revealed by the model.

Çok Boyutlu Yaklaşım ile Ürün Performans Ölçümü: Deneysel Bir Çalışma

Abstract

Kullanılabilirlik, ürün tasarımının ve kullanımının başarılı olmasını sağlayan önemli bir konu olarak kabul edilir. Günümüzde kullanıcıların birçok görevi yerine getirmelerini sağlayan ve yazılım ile donanımsal yönleri olan akıllı telefonlar için ise kullanılabilirlik son derece kritik bir öneme sahiptir. Bu çalışmada akıllı telefon kullanıcılarının beklentileri dikkate alınarak tasarım, müşteri odaklılık, kalite, inovasyon, kullanılabilirlik ve kullanıcı algısı değişkenlerini içeren kavramsal bir kullanılabilirlik değerlendirme modeli önerilmiştir. Önerilen modelin güvenilirliği ve geçerliliği, 417 akıllı telefon kullanıcısından toplanan anket verileri ile yapısal eşitlik modeli (YEM) kullanılarak test edilmiştir. Bulgular ve sonuçlar, akıllı telefon tasarımcıları ve pazarlama çalışanlarına akıllı telefonların kullanılabilirliği için kullanıcıların ihtiyaçlarını tespit etmelerini sağlarken; kullanıcılara ise modelin oluşturduğu indeks puanlarına göre akıllı telefonlara ait kritik yönleri gözlemlemede stratejik bilgiler sağlamaktadır.
