    • Business Resilience
      Covid, Brexit, financial crises, cyber-attacks, labour strikes, key employees turnover… businesses are now confronted to a vast range of possible disruptions often threatening not just their profits but also their survival. This course offers in-depth exposure to the latest knowledge, tools and frameworks relevant to business resilience, that is the capability of a business to survive and minimise costs incurred when facing disruptions. Its structure reflects the three different levels driving business resilience, namely: Strategic resilience: capability of designing or changing the business model (products offered, markets targeted) in response to actual or possible disruptions (instructor Julian Birkinshaw); Operational resilience: capability of maintaining existing core business activities when facing disruptions (Jérémie Gallien and Alex Yang); Personal resilience: capability of coping with stress-provoking events while reducing adverse experience and stress symptoms (Dan Cable).
