Director of Business Research, Lux Magi Ltd
David Petchey is an IT architect with 27 years’ experience in investment banking covering many products and many parts of the business process from research through to accounting and regulatory. He has served as business architect lead on 3 separate accounting engines, inventing a radical new architecture to support more sophisticated rule sets representing complex accounting treatments and regulatory mandates. For the last 7 years he has had a lead architect role, focussed on using Business Decisions and Decision Modelling (in DMN) to represent executable Business Requirements in accounting and treasury compliance. This allowed the addition of structure, clarity and brevity to proposed rulesets.
During one of his engagements Mr Petchey ran a masterclass on the benefits of using Decision Management techniques using real examples. In the examples used, a 90-98% reduction in rule size was demonstrated along with an explicit representation of what data is used to make decisions and how that data is used.
David is co-founder of Lux Magi Financial Rules and is currently working on ways to better integrate machine learning and artificial intelligence with Decision Modelling.
