Short answer

Prioritize user research and iterative usability testing when designing digital products, especially those intended for mobile use and specific functional tasks.

Field: User-Centred Design
Source: Reference Services Review (2017)
Method: Case Study with Usability Testing
Evidence: Strong effect

A systematic, user-centred development process for a mobile information literacy application resulted in a prototype that students found highly usable and valuable for research tasks. This user-centred design research insight is drawn from a 2017 study published in Reference Services Review. Using Case study with usability testing, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize user research and iterative usability testing when designing digital products, especially those intended for mobile use and specific functional tasks.

Mobile Information Literacy App Prototype Achieves High Usability Scores

A systematic, user-centred development process for a mobile information literacy application resulted in a prototype that students found highly usable and valuable for research tasks.

Reference Services Review · 2017

Key Findings

01Students expressed a need for mobile access to digital collections and reference support.
02The developed mobile application prototype received positive feedback during usability studies.
03The prototype was deemed ready for further testing with a broader student population.

Application

Design takeaway

Prioritize user research and iterative usability testing when designing digital products, especially those intended for mobile use and specific functional tasks.

How to apply

Conduct user surveys and interviews to identify unmet needs, then develop and test prototypes iteratively with representative users before full-scale development.

Project actions

01Clearly define the target user group and their specific needs early in the design process.
02Use a phased approach to development, incorporating feedback at each stage.

Method & Evidence

AimTo investigate the development and usability of a mobile application designed to support students' information literacy and research activities.

MethodCase Study with Usability Testing

ProcedureA survey was conducted to understand student technology use and needs. Based on these findings, a mobile application prototype was developed using an analysis, design, development, implementation, and evaluation (ADDIE) model. Alpha and small-scale usability testing were then performed on the prototype.

ContextAcademic library services and student research support.

Variables

IVUser needs and feedback, development methodology (ADDIE).

DVUsability of the mobile application, student satisfaction.

CVTarget user group (students), research task context.

Strengths & Limitations

Strengths

+Systematic development approach.
+Inclusion of user feedback throughout the process.

Limitations

The sample size for usability testing was small, and the study was conducted within a specific academic context, which may limit generalizability.

Reliability & validity

The study's validity is supported by its systematic methodology and direct user feedback. Reliability could be enhanced by larger sample sizes and more standardized usability metrics.

Think critically

How might the findings of this study be applied to the development of digital tools for other user groups or in different contexts beyond academic libraries?

Design Principles

"Design digital products with a user-centred methodology, incorporating feedback loops throughout the development lifecycle to ensure usability and relevance."

This research demonstrates the effectiveness of a structured approach to developing digital tools that cater to user needs. By involving users throughout the design and testing phases, designers can create more intuitive and effective solutions that integrate seamlessly into users' workflows.

What This Means for Your Design

When making an app for students to help them with research, it's really important to ask them what they need first and then test the app with them as you build it to make sure it's easy to use.

How to use in your project

1.Reference this study when justifying the need for user research and iterative testing in your design project.
2.Use the ADDIE model as a framework for your own design and development process.

Paragraph starter

The development of the Research Plus™ mobile app, as detailed by Mullins (2017), highlights the critical role of user-centred design and iterative testing in creating effective digital tools. By employing a systematic approach that began with understanding student needs through surveys and progressed through prototype development and usability testing, the project successfully created an information literacy application that users found valuable and easy to use, demonstrating a strong correlation between user involvement and product success.
