Understanding: reframing automation and assurance
Robin Bloomfield

TL;DR
This paper emphasizes the importance of explicit understanding in safety and assurance cases for socio-technical systems, proposing a structured approach to improve decision-making and evaluate epistemic impact.
Contribution
It introduces a conceptual foundation based on Elgin's epistemology and operationalizes understanding through Assurance 2.0, including artefacts like Understanding Basis and Personal Understanding Statement.
Findings
Structured argumentation enhances explicit understanding.
Automation can both improve artefact production and weaken understanding.
Initial evaluation directions for efficacy and epistemic impact are proposed.
Abstract
Safety and assurance cases risk becoming detached from the understanding needed for responsible engineering and governance decisions. More broadly, the production and evaluation of critical socio-technical systems increasingly face an understanding challenge: pressures for increased tempo, reduced scrutiny, software complexity, and growing use of AI generated artefacts may produce outputs that appear coherent without supporting genuine human comprehension. We argue that understanding should become an explicit, assessable, and defensible component of decision making: what developers, assessors, and decision makers grasp about system behavior, evidence, assumptions, risks, and residual uncertainty. Drawing on Catherine Elgin's epistemology of understanding, we outline a conceptual foundation and then use Assurance 2.0 as an engineering route to operationalize using structured…
