The Black Swan’s Gaze
To be published in Q4 2025
The purpose of this book
This second volume in the Ensuring Resilience series is devoted to Business Impact Analysis (BIA), the foundational step in any continuity approach. Its objective is to provide organisations with a clear and rigorous method for identifying their critical activities, measuring the impact of an interruption and defining restoration priorities.
This volume establishes the essential link between the strategic vision set out in Volume 1 and the operational implementation that will follow in subsequent volumes.
What you will discover
- A unique top-down methodology: from business objects to functions, from functions to processes, then to applications and infrastructure.
- Impact assessment criteria (financial, human, regulatory, reputational) and their translation into continuity objectives (RTO/RPO).
- Practical tools: collection grids, interview templates, assessment checklists, numerical examples.
- The importance of involving both business teams and IT managers in a collaborative and realistic analysis.
- Fictional anecdotes and real-life cases that illustrate common mistakes and best practices.
What you will learn
Through this book, you will learn how to:
- Conduct a structured and reproducible business impact analysis.
- Link business priorities to the necessary technical and human resources.
- Communicate effectively between business and IT to build a shared vision of priorities.
- Define measurable continuity objectives that can be directly used in BCP and DRP plans.
What you will be able to do after reading

- Map the business and technical dependencies of your organisation.
- Clearly identify your critical activities and the conditions necessary for their survival in the event of a crisis.
