In the beginning there was Continuous Integration.

“Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily - leading to multiple integrations per day ... Many teams find that this approach leads to significantly reduced integration problems and allows a team to develop cohesive software more rapidly.”

- Martin Fowler

An interesting quote ...

“We need to get serious about breaking down the silos within our organisations, getting customer focused and driving some real change in the industry. The biggest danger Youi represents is that they will change the expectation and our organisations will not be ready for it.”

- Isabel Frederick, Medibank Private
