Wartime Supply Chain Resilience: Crisis Management Capabilities of Ukrainian Agribusinesses

This study explores how Ukrainian agribusinesses manage operations under prolonged geopolitical disruption by examining the wartime resilience strategies and pathway divergence of Kernel and Astarta. Drawing on a qualitative comparative case study approach, the paper combines the 4R (Reliability, Relationships, Responsiveness, and Resilience) framework with dynamic capabilities theory. The 4R framework is used to identify the main dimensions of wartime resilience, while dynamic capabilities theory explains how firms sense emerging threats, seize adaptive opportunities, and transform resources, routines, and stakeholder relationships over time. The findings highlight resilience as a multidimensional and evolving capability shaped by context-specific assets and stakeholder networks. This study provides rare insights into strategic organizational adaptability in active conflict zones and contributes to the resilience and dynamic capabilities literature in the context of extreme, long-term disruptions.

A strategic analysis of operational resilience and the mandate for antifragility: Integrating agentic artificial intelligence within volatile financial ecosystems

The financial services sector stands at a critical inflection point where traditional models of operational resilience are no longer adequate for the velocity and complexity of modern risk. This paper examines the strategic imperative for financial institutions to transition from reactive, compliance-centric risk management towards a state of anti-fragility: the capacity not merely to withstand systemic stress, but to improve because of it. Drawing upon empirical industry data, regulatory developments, and a practical case study from Atom Bank, the paper explores how agentic artificial intelligence is fundamentally reshaping the disciplines of operational resilience, third party risk management, and cyber security. Key themes include the maturity gap in configuration management database infrastructure, the systemic threat posed by supply chain vulnerabilities, the rise of artificial intelligence (AI)-enabled adversarial actors and deepfake fraud, and the concentration risk inherent in hyperscaler dependency. The paper challenges the prevailing assumption that anti-fragility is a well-established or universally accepted framework, presenting it instead as an aspirational model that demands significant cultural, technological, and governance transformation. Readers will gain a structured understanding of the current threat landscape, practical strategies for active resilience, and a framework for integrating AI-driven workflows into a unified institutional risk architecture.

A system dynamics approach to assessing organisational resilience in digitally disrupted sociotechnical systems

Organisational resilience is a critical capability for complex sociotechnical systems facing persistent digital and cyber disruptions. Yet, it remains difficult to measure dynamically, particularly in service-oriented infrastructures such as national payment systems. This study examines whether a System Dynamics (SD) modelling approach can provide a robust, quantifiable representation of resilience behaviour in the South African National Payment System (NPS) under continuous cyber disruption. Using a Design Science Research paradigm, the study develops and evaluates a multidimensional resilience assessment artefact. The research combines a systematic literature review, Delphi-based expert validation, causal loop diagram and stock-and-flow simulation modelling, employing dimensionless normalisation and sensitivity analysis grounded in frontier SD research to quantify “soft” resilience variables. Simulation results show that resilience emerges from interactions among adaptive capacity, recoverability, robustness, and financial resource allocation. Targeted investment in adaptive capacity and recoverability reinforces long-term resilience, while excessive focus on robustness risks systemic rigidity and reduced adaptability. Organisational resilience depends on managerial choices about resource allocation and capability development. Investing in adaptive capacity and recoverability reinforces feedback loops that sustain performance during disruption. The study contributes a feedback-based resilience assessment model and provides a decision-support framework for evaluating resilience strategies in a digitally disrupted environment.

A hierarchical trajectory model of cyber resilience in safety-critical cyber-physical systems

Resilience in safety-critical cyber-physical systems is not a settled concept. It carries competing meanings inherited from four distinct intellectual traditions—materials science, ecology, safety engineering and cybersecurity—each with its own definition of what a successful outcome looks like. This tension is not merely academic. It produces operational frameworks in which robustness, adaptability, safety constraint and recovery are treated as equivalent attributes, their structural differences obscured. The result is guidance that can satisfy audit requirements while leaving complex systems vulnerable in ways that compliance-driven requirements cannot detect. This paper addresses that gap in three steps. First, it reconciles the engineering and ecological resilience traditions through the Cyber-Compatibilism principle. Second, it defines a hierarchical, CPS-specific structure of resilience domains spanning safety, engineering, organisational, governance and contextual attributes. Third, it develops a domain-attributed trajectory model that maps each domain to the phase of disturbance it dominantly shapes and to the corresponding NIST cyber resilience goal. No domain operates in isolation: each phase emerges from the combined action of attributes across all domains, with one typically dominant but nonsufficient alone. The model is informed by two industrial case studies and a physical safety-critical testbed representative of those systems; the empirical evidence base is reported in a companion paper.
