Abstract

Bu çalışmada, literatürde “sihirbaz” olarak isimlendirilen ve birbiriyle ilgili ardışık olacak şekilde farklı adımlar içeren arayüzlerdeki tasarımsal farklılığın, kullanılabilirlik açısından ne derece değişkenlik gösterdiğinin incelenmesi amaçlanmıştır. Bu amaç için, Kırklareli Üniversitesi öğrenci ve personellerinin e-posta şifrelerini sıfırlamak amacıyla kullandıkları web tabanlı bir sistemden faydalanılmıştır. Bu sistemin, hizmete açıldığı zamanki arayüzü (A) ile tasarımsal farklılık içeren bir diğer yeni arayüzü (B), kullanılabilirlik perspektifinden A/B test yöntemiyle karşılaştırılmıştır. Her iki arayüz sihirbaz özelliğinde olup, B arayüzü ile A arasındaki fark, kullanıcıların geçtikleri adımların isimlendirilmiş olarak B arayüzünde yer almasıdır. Çalışma sonuçlarında, etkililik bakımından arayüzler arasında fark bulunamamıştır. Diğer taraftan, Mann-Whitney U testi B arayüzünün A’dan daha verimli bir kullanıcı deneyimi oluşturduğunu göstermiştir (p<0,01). Spearman Korelasyon ölçümleri, B arayüzünde verimlilik ile memnuniyet arasında bir ilişki ortaya çıkarmazken (p=0,467), A arayüzünde zayıf da olsa negatif yönde bir ilişkiyi gözler önüne sermiştir (rs = -0,137, p<0,05). Çalışmada ortaya çıkarılmış olan tüm bulgular detaylı bir şekilde açıklanmış ve gelecekte kullanılabilirliğe yönelik yapılacak olan çalışmalarda dikkat edilebilecek noktalara ışık tutulmaya çalışılmıştır.

Abstract

This study aims to examine to what extent design difference in the interfaces, which are called “wizards” in the literature and include different steps related to each other, varies in terms of usability. For this purpose, a web-based system, which the students and the staff of Kırklareli University use to reset their e-mail passwords, was used. The interface (A) of this system when it was put into service and another new interface (B), which has a design difference, were compared with the A/B test method from the perspective of usability. Both interfaces have wizard features; the difference between the B interface and A is that the steps users go through are named in interface B. In the results of the study, no difference was found between the interfaces in terms of effectiveness. On the other hand, the Mann-Whitney U test showed that interface B creates a more efficient user experience than A (p<0,01). While Spearman Correlation measurement did not reveal a relationship between productivity and satisfaction at interface B (p=0,467), it revealed a negative relationship, albeit weakly, at interface A (rs = -0,137, p<0,05). All the findings revealed in the study were explained in detail, and it was tried to shed light on the points that could be considered in future studies on usability.
