UCD approach boosts e-commerce usability by 67% for SMEs

Why It Matters

For businesses, especially smaller ones, a well-designed digital interface is crucial for efficient operations and customer satisfaction. UCD provides a structured framework to ensure that the final product directly addresses user needs and operational challenges, leading to tangible improvements in task completion and overall experience.

Key Finding

The user-centered design process resulted in an e-commerce website that was highly usable, with users successfully completing most tasks efficiently and reporting excellent overall satisfaction.

Key Findings

• Achieved a 67.86% task completion rate.
• Average task time was 91.66 seconds.
• Overall relative efficiency was 66.96%.
• Five out of six User Experience Questionnaire (UEQ) dimensions were rated as 'Excellent'.

Research Evidence

Aim: How can a User-Centered Design approach be applied to develop an e-commerce website that streamlines order processing, enhances user autonomy, and reduces the operational burden for small businesses?

Method: Case Study with Usability Evaluation

Procedure: The study involved iterative stages of user research, requirements specification, interface design, and usability evaluation. A high-fidelity prototype was developed and tested with participants. Usability metrics based on ISO/IEC 25022 were collected, alongside user satisfaction data from the User Experience Questionnaire (UEQ). The final system was then implemented and integrated with relevant tools for payment and order management.

Sample Size: 65 participants (56 valid responses)

Context: E-commerce website design for small and medium-sized enterprises (SMEs)

Design Principle

Design solutions iteratively based on direct user feedback and empirical usability testing to optimize user experience and task efficiency.

How to Apply

When designing any digital interface, especially for businesses aiming to improve customer interaction and operational flow, integrate UCD principles by conducting thorough user research, creating prototypes, and performing rigorous usability testing before final implementation.

Limitations

The findings are specific to the context of Indonesian SMEs and may require adaptation for different cultural or market settings. The sample size, while adequate for a case study, might limit generalizability.

Student Guide (IB Design Technology)

Simple Explanation: Using a user-centered approach to design an online shop makes it easier for customers to use and helps the business run more smoothly.

Why This Matters: This research shows that designing with the user in mind leads to better, more effective products, which is essential for any design project aiming for success.

Critical Thinking: To what extent can the specific usability metrics (e.g., task completion rate, efficiency) be directly attributed to the UCD process versus other factors like the chosen technology stack or the participants' prior digital literacy?

IA-Ready Paragraph: The application of a User-Centered Design (UCD) methodology, as demonstrated in research by Nisa, Wahyuningrum, and Sambath (2025), provides a robust framework for developing effective e-commerce solutions. Their case study highlighted significant improvements in usability metrics, including a 67.86% task completion rate and high user satisfaction, underscoring the value of iterative user research and testing in streamlining digital operations for small businesses.

Project Tips

• Clearly define your target user group and their specific needs early in the design process.
• Use prototyping tools to quickly create and test different design ideas with potential users.

How to Use in IA

• Reference this study when justifying the use of UCD in your design process, particularly if your project involves creating a digital interface or improving user interaction.

Examiner Tips

• Demonstrate a clear understanding of the UCD process and how each stage contributes to the final design outcome.

Independent Variable: ["Application of User-Centered Design (UCD) methodology"]

Dependent Variable: ["Usability metrics (task completion rate, task time, relative efficiency)","User satisfaction (UEQ dimensions)"]

Controlled Variables: ["Participant demographics","Specific e-commerce tasks","Usability evaluation tools and metrics"]

Strengths

• Practical application of UCD in a real-world SME context.
• Use of established usability and user experience evaluation methods.

Critical Questions

• How would the results differ if a different user research method (e.g., ethnography) was employed?
• What are the long-term impacts of this UCD-driven website on the business's sales and customer retention?

Extended Essay Application

• Investigate the scalability of UCD principles for larger e-commerce platforms or different types of digital services.
• Explore the economic benefits and return on investment for SMEs adopting UCD in their digital transformation journey.
