Applying Data Exploration & Discovery techniques to BCBS 239

Time is fast running out for G-SIBS (and indeed D-SIBS) to demonstrate compliance with the principles of BCBS 239.  Many surveys have been conducted by firms such as EY, McKinsey and Deloitte – none of which paint a particularly pretty picture in terms of readiness.
