Patterns of Legacy Displacement
by Rob Horn
Every organisation has legacy systems. Six month old startups or 30 year old giants of industry. These are systems rich in the heritage of your organisation. They are also those systems blocking transformation into a modern digital business.
I have spent most of the last couple of decades helping organisations overhaul their legacy systems. In doing this we’ve learned a great deal about what works, and seen many paths that lead to failure.
In this talk I will tell the tale of one such programme, and describe how several of the Patterns of Legacy Displacement were applied to help the client achieve their business outcomes.
The talk is drawn from material being produced in collaboration with Martin Fowler, James Lewis and Ian Cartwright.
