While resources and infrastructure support software development, the human element—including developer skill, management influence, and effective information flow—is the primary determinant of software product quality. This human factors research insight is drawn from a 2015 study published in LUTPub (LUT University). Using Grounded theory with 40 interviews from 13 companies, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Focus on empowering and supporting the human element within your design and development teams, as this will have the most significant impact on the quality of the final product.
Human expertise, not just tools, dictates software quality.

Key Findings
- 01Human factors are the primary determinants of software product quality.
- 02Tools, infrastructure, and resources have a positive impact but are secondary to human influence.
- 03Organizational structures, operational modes, and information flow significantly affect software quality.
- 04Software development managers play a crucial role in influencing developer productivity and product quality.
- 05Challenges in software testing can negatively impact software quality.
Application
Design takeaway
Focus on empowering and supporting the human element within your design and development teams, as this will have the most significant impact on the quality of the final product.
How to apply
When designing software development processes or evaluating existing ones, conduct thorough user research with developers and managers to understand their challenges and needs, and prioritize solutions that enhance human collaboration and expertise.
Project actions
- 01When designing a system, consider how users (developers, testers, managers) will interact with it and how it might affect their performance and collaboration.
- 02Think about the 'human factors' in your design – not just physical ergonomics, but also cognitive load, communication needs, and team dynamics.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Empirical data collection from multiple companies provides real-world insights.
- +Grounded theory approach allows for emergent understanding of complex factors.
Limitations
The findings are qualitative and specific to the companies studied, so direct application to all contexts may require adaptation. The minimal impact of development methods might be due to the specific methods studied or the companies' implementation of them.
Reliability & validity
The study's reliance on interviews and grounded theory provides rich qualitative data but may have lower inter-rater reliability for coding. The findings' validity is strengthened by triangulation across multiple companies, but generalizability might be limited.
Think critically
If human factors are so critical, how can design projects effectively measure and improve these often intangible elements within a development team?
Design Principles
"Human-centric development processes are paramount for achieving superior product quality."
This insight emphasizes that investing solely in advanced tools or processes is insufficient for achieving high software quality. Design teams must prioritize understanding and nurturing the human factors involved in development, such as team dynamics, individual expertise, and effective communication, to truly enhance product quality.
What This Means for Your Design
Good software isn't just about having the best tools; it's mostly about having skilled people who work well together and are managed effectively.
