Requirements Strategy for Managing Human Factors in Automated Vehicle Development

Amna Pir Muhammad, Alessia Knauss, Eric Knauss, Jonas Bärgman

TL;DR

This paper investigates how to integrate Human Factors (HF) requirements into automated vehicle (AV) development using the Requirements Strategy framework. Through 13 semi-structured interviews with HF and requirements professionals from the global automotive sector, it analyzes three building blocks—organizational ownership, structural requirement models, and HF work/feature flows—and derives eight propositions. Findings reveal largely context-dependent support: clear ownership and lifecycle-focused HF requirements generally aid integration, while structuring, traceability, and decomposition yield mixed results across organizations. The study highlights the need for context-tailored Requirements Strategies in agile AV development to balance rigor with flexibility, and it identifies solution spaces for practitioners to enhance HF integration in real-world settings.

Abstract

The integration of human factors (HF) knowledge is crucial when developing safety-critical systems, such as automated vehicles (AVs). Ensuring that HF knowledge is considered continuously throughout the AV development process is essential for several reasons, including efficacy, safety, and acceptance of these advanced systems. However, it is challenging to include HF as requirements in agile development. Recently, Requirements Strategies have been suggested to address requirements engineering challenges in agile development. By applying the concept of Requirements Strategies as a lens to the investigation of HF requirements in agile development of AVs, this paper arrives at three areas for investigation: a) ownership and responsibility for HF requirements, b) structure of HF requirements and information models, and c) definition of work and feature flows related to HF requirements. Based on 13 semi-structured interviews with professionals from the global automotive industry, we provide qualitative insights in these three areas. The diverse perspectives and experiences shared by the interviewees provide insightful views and helped to reason about the potential solution spaces in each area for integrating HF within the industry, highlighting the real-world practices and strategies used.
