 Problem Statement
The applicability of VR in evaluating user satisfaction and perceived quality of buildings.
Can researchers apply immersive virtual environments (IVEs) to measure psychometric variables and user feelings of a building? Can VR potentially be effective and useful in creating accurate mental models for users?

Research Approach and Methodology
VR enables people to experience the feeling of actually being in another place through a computerized scenario that simulates an immersive and lifelike experience grounded in reality.

This research applied the world’s most open and advanced real-time 3D creation tools and professional 3D computer graphic programs to model and simulate building and provide teleportation in virtual reality.

In this study, quantitative research, in-person & moderated usability testing, and comparative analysis were conducted to examine the applicability VR approach to compare psychometric variables and users' relative evaluation and feelings from a simulated building in VR with a real building in a realistic environment.
​
​In addition, quantitative research, remote & unmoderated usability testing, and comparative analysis were conducted to examine the applicability video recording approach to compare psychometric variables and users' relative evaluation and feelings from a high-definition recording of a real building with that building in a realistic environment.

  As a result, VR can simulate the physical environment, provide teleportation, and create realistic interaction with objects, which can create a new approach to measuring and evaluating psychometric variables when conducting UX research.

 Problem Statement
What is a practical framework for implementing agile project management in Trello in conducting UX services for any new and existing products, services, or processes throughout the product development life cycle?
​
The agile methodology brings rapid changes and flexibility to a business, which is why it is preferred by businesses and teams.  
Trello gives the team the ability to apply the agile methodology to effectively handle projects and tasks. It’s easy to use and offers a visual approach to project management. Teams can use Trello’s board, lists, and cards to create visual representations of their tasks. The tasks are moved through predetermined stages to track progress and identify bottlenecks. 

Companies apply Trello for implementing agile project management in conducting UX research and UX design on new and existing products, services, or processes.

Implementing all phases of the project management process in an agile environment makes bewilderment for these companies, especially managing a large number of complex projects.

Research Approach and Methodology
Through explorative, remote & moderated usability study on some international companies working on UX research and UX design projects, the functionality, usefulness, usability, and desirability of this agile framework defined in Trello were evaluated.
The framework was revised and redesigned several times based on the feedback received from project managers. 

​As a result, a practical framework in Trello was proposed for implementing all phases of agile project management in conducting UX research and UX design for any new and existing products throughout the product development life cycle. This framework includes all the following phases of project management that are aligned with scrum and agile environments:
- Initiate the project
- Planning the project
- Executing the project
- Monitoring & controlling the project
- Closing the project

 Problem Statement
Our client was a biomedical engineering company that designs and manufactures skull structures with Polyether ether ketone (PEEK) material a semi-crystalline organic thermoplastic polymer. PEEK is the preferred material for cranioplasty implants in hospitals around the world. It is the “gold standard” for large defects and also well-suited for small and standard defects.

Cranioplasty is a surgical procedure to repair bone defects in the skull that is left behind after a previous operation or injury. The reasons for Cranioplasty are:    

- When a cranial defect exposes the brain to damage. 

- When cranial correction improves the patient's neurological function. 

- When the shape and appearance of the deformed skull affect the appearance and self-confidence of the patient. 

- When injuries and headaches caused by previous surgery bother the patient.

Many companies are designing and manufacturing cranial structures using different materials such as titanium (MESH) and bone cement (PMMA). 

Our client wanted to evaluate competitors' products and services to determine their strengths, weaknesses, and existing product problems. In addition, they wanted to gain insight into the user feedback on their products and services.

Research Approach and Methodology
This research study included comprehensive market research, competitive analysis, and UX research. In this qualitative study, explorative usability studies including both remote & in-person unmoderated usability tests were conducted to gather detailed insights about user feedback.

In this research study, we selected two groups of cranioplasty surgeons, one of whom implanted the product into the patient's skull using PEEK material, and the other using different materials such as titanium (MESH) and bone cement (PMMA). The group of surgeons was a valid sample because we could get their feedback as well as that of their patients.

Through this process, we evaluated the expectations, needs, pain points, ease of use, and desirability of each product from the perspective of surgeons and patients.

As a result, we provided the company with a clearer understanding of patients' and surgeons' behaviors, expectations, needs, and preferences. Through competitive analysis, we discover the advantages and disadvantages of the company's products and services compared to its competitors. We also identified pain points and areas for opportunity in the current products and services. We provided valuable insight and solutions to improve the products and services.

 Problem Statement
To address people's physical and mental health, in the situation of the covid-19 epidemic, what home edition multi-functional equipment can greatly meet people's fitness expectations, so they don't need to go to public gyms?

Research Approach and Methodology
Given COVID 2019 and people’s desire to exercise at home, the ISS team came up with the idea of designing a multifunctional home edition gym equipment.

To turn his idea into reality, a feasibility study and preliminary analysis as well as market research were conducted to determine the market interests, business strategies and operations, organizational benefits, and resources needed to turn the idea into reality.

In the next step, conducting strategic research as the first stage of the product development lifecycle, exploratory and qualitative research was designed to investigate customers’ expectations of a home edition gym equipment, to find out which core muscles people are looking to strengthen with equipment, and to figure out the problems in existing gym equipment in the market (i.e., problem statement) in the market. Building user personas was one of outcomes of this stage.

Then in-depth design and tactical research was conducted during the design phase of the product development lifecycle to figure out all steps, resources, and equipment for changing the idea into a prototype.

​Based on the results obtained from the research, multifunctional gym equipment was designed that is in demand by most people. After building a prototype, through post-launch research, the product was tested on the users. In-person & moderated, and explorative usability study was conducted to evaluate the usefulness, usability, and desirability of the product from the perspective of its users. Product happiness, engagement, adoption, retention, and task success were some of the constructs examined in this phase. The product was redesigned several times based on the feedback.

As a result, this equipment is patented and registered with the United States Patent and Trademark Office (USPTO).
