Once an organisation accepts it has a subledger problem, the next question is how to actually do something about it - and the temptation, particularly where the problem is large and visible, is to fix the entire balance sheet in one programme. Mike Dolan has a blunt view on how that goes, and a count of how many clients he has seen pull it off.

In this closing segment, host Mark Aubin asks Dolan, Partner at Ernst & Young, to lay out the transformation pathways that do work: which asset class to start with, what a finance team learns from a first wave that no amount of planning delivers, and how to tell universal requirements apart from product-specific ones before that distinction gets expensive. Dolan also sets out why EY has taken this on, and how it connects to eighty years of audit history and the trust agenda underneath it.

Adrian Mustafa, Product Director at SAP Fioneer, closes with an invitation and a challenge - including advice on vendor evaluation that runs against his own commercial interest, and details of a second session where the team will move past the concepts and show the Cloud Accounting Subledger working on real financial instruments.
