Perceived Quality for Dishwashers, A Benchmarking Study

 ARÇELİK A.Ş., Ankara - Dishwasher Division| 2011


The aim of the study was to investigate product qualities which constitutes added value for the dishwasher design and evaluate the two products developed by the firm in terms of their perceived qualities. Data was gathered through a benchmarking study which involved 6 different dishwasher designs to be evaluated by 32 participants in a laboratory setting. As a result of the study, design principles, which can raise the competitive power of the firm and should be considered while improving and developing interior and exterior parts of the dishwasher, were suggested.




Investigation of Changesi in Dishwasher Rack Design

ARÇELİK A.Ş., Ankara Dishwasher Division | 2010

In this study, new rack design prototype was evaluated with the previous rack systems, in the labaratory environment. The study was conducted with 30 users with the success scale which was developed during the previous studies. The success of the prototype was evaluated according to the targetted qualities


Washing Machines Rack System Field Tests

ARÇELİK A.Ş., Ankara Dishwasher Division | 2008

In this study, a new dishwasher rack system was evaluated, in compliance with user expectations and usage patterns.

The study was carried out for 4 weeks, with a total number of 51 users from different cities. New rack systems were installedto users’ machines and users' experiences of the new rack systems were observed. With the aim to give the design directionsall user experiences during the usage was questioned in depth, using different research techniques.


User Requirements and Expectations Analysis for Dishwashers, Benchmarking and Dishwasher Rack Design

ARÇELİK A.Ş., Ankara Dishwasher Division | 2007

The project aimed to conduct a user-centered design process to develop a dishwasher rack that conforms to user requirements and preferences. In the first phase, dishwasher rack usage was explored with user interviews on the photographs of their own dishwasher racks. Then the users were asked to evaluate competing brands’ rack designs in a detailed way using a structured interview based on repertory grid technique. In the third phase, a questionnaire study was conducted to evaluate the lab study findings. The results of these multiple studies were re-examined together to develop a model that explains the critical relationships and variables. Based on this model, design recommendations were developed and classified in terms of core concepts such as cost and flexibility. Following the presentation of the study findings, research results were validated, by conducting a comparative study in the lab environment.
