Managing the complexity and inter-dependencies of IT systems is vital for day to day management, as well as reducing the likelihood and impact of cyber attacks. All best practice management frameworks such as ITIL, 27001, CoBit, NIST, etc emphasize the importance of understanding and managing IT systems complexity – but actually doing it in practice is not simple. If you’d like to know why IT systems continue to “fail” without faults or cyber-attacks, then you’ll find this talk very illuminating.
