I had been a researcher at the first independent usability lab in Turkey, METU/BILTIR – UTEST Product Usability Unit from its establishment in 2002. Throughout my 8 years wrok, I conducted research both for academia and industry and blended knowledge and experience from both domains to develop realistic design solutions based on scientific grounds.

I have always enjoyed contributing to the usability practice in the industry and exploring the dimensions of user emotions and satisfaction, both in the lab and real-context studies. I am proud to say that this experience provided me a wide-ranging expertise covering consumer products, home appliances, automotive products and online systems.

ARÇELİK A.Ş. Ankara – Dishwasher Division | 2008

The alphanumeric screen-based dishwasher interface was evaluated with expert analysis to provide solutions to usability problems. The product was in the late development stage, so we developed design recommendations without changing the screen layout. We prototyped the entire interface with computer based animations. I was responsible with Defining and classifying usability problems, developing design recommendations and Preparing   prototypes of the proposals on Adobe Photoshop and MS Powerpoint.

Interface Design for Two Arçelik Dishwasher Models Based on Product Concepts

ARÇELİK A.Ş. Ankara Dishwasher Division | 2005

Based on the firm’s marketing objectives, design alternatives for the ‘single button’ dishwasher interface concept were developed. Two interface alternatives, which differed in functionality and interface elements, were proposed for upper and lower market segments. The meaning of ‘single button’ concept was examined in the initial stage and the functional specifications for both models were defined. Cognitive walk-through was used as a method to develop functional flow diagrams and the resulting interface alternatives were modeled in detail. I was a part of the expert review and developed design recommendations based on usability criteria.

An alphanumeric screen-based dishwasher model, Arçelik Ecologist, was evaluated based on usability criteria and user requirements, by a comparative study with two competing brands’ models. The study comprised of usability tests, motion analysis to explore perceived quality in the first impression, user requirements questionnaires and focus group studies to develop long-lasting design guidelines. In the project I was responsible with interviewing with the test participants, moderating user tests, conducting user requirements analysis and reporting of the test process, methodology and outcomes

Usability Testing and User Requirements Analysis of an Oven Interface

TEBA A.Ş. Oven Division [Project partners: TUDelft/Witlab, Lougborough Univ./HUSAT ] | 2003

In the context of EU supported “Product Safety and Usability Testing Project” a screen-based intelligent oven interface in an early design phase was evaluated by a joint study with Loughborough University from UK, and TUDelft from the Netherlands. Cultural differences that may affect oven use were explored by first conducting on-site interviews to examine the diversity in contextual factors and user requirements. Then the interface prototype was evaluated with expert analyzes and usability tests in three countries. My responsibilities in the project included questionnaire design, use context research on kitchen and oven use and documentation of the research outcomes.

User Requirements Analysis & Contextual Research for Dishwasher Rack Design

ARÇELİK A.Ş., Ankara Dishwasher Division | 2007

The project objective was to develop a dishwasher rack design that conforms to user requirements and preferences. It was a successfully conducted user-centered design process which combined several research methods.

In the first phase, dishwasher rack usage was explored with user interviews based on the photographs of their own dishwasher rack usage. They were asked to evaluate competing brands’ rack designs in a detailed way using a structured interview derived from the Repertory Grid Technique.  Then the lab study findings were evaluated with an online questionnaire. 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.

I was responsible in every step of the project, including market research, contextual research developing the interview technique based on RGT, interviewing with users and active observation, developing design recommendations and visual presentation of the design recommendations to the client.

User Requirements Analysis & Usability Testing of a Washing Machine Interface with Benchmarking

ARÇELİK A.Ş. Istanbul – Tuzla Washing Machine Division | 2006

The project aimed to develop design guidelines and novel interface concepts for the screen-based washing machine interfaces. The study started with a benchmarking and usability study that compares the product and competing models’ interfaces with user participation. The products were evaluated in terms of usability and usefulness, as well as perceived quality measures in the first impression. In addition to this core study, general information regarding usage and usefulness of product functions was gathered with questionnaire and interviews. This information was further supported with a large-sample questionnaire on user preferences and requirements related to product use. My responsibilities were interviewing with the test participants, moderating the user tests, defining usability problems and user requirements and reporting the findings.

Perceived Quality Evaluation in Midibus Design

TEMSA A.Ş | 2008

The aim of the project was develop design guidelines that would lead the firm in the midi-bus interior and exterior design. The relationships between the perceived quality variables and product components were defined and their effects on the user evaluation criteria were explained. Two complementary methods were used in the study. In the first phase, the midi-bus was evaluated with two competing brands’ models with a comparative lab study based on driver and passenger examinations. The dominant constructs regarding perceived quality and the main product components that affect user preferences classified by this way. The second phase was composed of developing an information system that would represent the findings and relationships to designers, in a way to be integrated in the design process. Therefore the main emphasis was on modeling the complex relationships between the product components and perceived quality dimensions, with clear representations and visuals. It was a long-lasting and engaging project for 8 months, I was involved in every step, designing the research methodology and user studies, test planning, moderating user studies, organizing the test sessions and analyzing the findings: transcription of results, developing the design recommendations and visualization of the research outcomes which was presented as an interactive CD database.

Determinants of Perceived Quality for Minivan Interior – Design Evaluation & User Research


The project aimed to define the specifications for the mini-van interior to increase the added-value in the consumer market. For this purpose, a model for the perceived quality for mini-van interiors was developed. In the first phase, the customer evaluations were observed at the purchase points through video camera installations and user interviews. The purchase criteria and related important car interior elements which affect the product’s first impact were classified in this way. In the second and core phase, the product was evaluated with a comparative study with two competing models with users at the lab environment, and the dominant product elements and assessment criteria were explored. A complementary eye-tracking study on 2-D images revealed more in-depth information about the user assessment process. At the final stage, the findings of the multiple methods were combined to develop design principles. I was responsible in the context research, questionnaire and interview design and application, test moderation analysis of the findings and reporting the outcomes.


User Requirements Analysis and Problem Specification for City Buses

TEMSA A.Ş. | 2007

The project aimed to reveal the problem areas regarding bus design to define the requirements for prospective studies. The first phase included a detailed comparative evaluation of the product with two competing models based on anthropometric dimensions, visibility, ergonomic qualities, control panel design, safety and passenger comfort. This study was followed by a contextual research including interviews with the drivers and passengers on user requirements, expectations and problems as well as contextual factors. Passenger and driver activities were further observed through installed video cameras in the buses during regular use period. In addition to this structured research, informal on-site observation and photo-documentation studies provided supportive information on the contextual factors during this phase. In the next step, defined problem areas were aimed to be verified and explored in detail through a large-sample questionnaire with city bus drivers. Based on the research outcome, the problem areas were defined and exemplified according to product type, contextual factors and perceived quality dimensions. An initial set of recommendations were developed for future studies and design improvements. My responsibilities were designing and conducting user studies, carrying out contextual studies, on-site documentation and making analysis of the context findings.
