Usability Insights for Requirements Engineering Tools: A User Study with Practitioners in Aeronautics
Abstract
Requirements Engineering plays a crucial role in
coordinating the different stakeholders needed for safe aeronautics
systems engineering. We conducted a qualitative study,
using interviews and mockups, with fifteen industrial practitioners
from four aeronautics companies, to investigate what tasks
are actually performed by requirements engineers and how current
tools support these tasks. We found that RE-specific tools
constrain engineers to a rigid workflow, which is conflicting with
the adaptive exploration of the problem. Engineers often start by
using general-purpose tools to foster exploration and collaborative
work with suppliers, at the expense of traceability. When
engineers shift to requirements refinement and verification, they
must use RE-specific tools to grant traceability. Then, the lack of
tool usability yields significant time loss and dissatisfaction.
Based on scenarios of observed RE practices and walkthrough,
we formulate usability insights for RE-specific tools to conciliate
flexibility and traceability throughout the RE process.
