Amazon's Simple Workflow Service (SWF) in AWS provides a model of workflow that is simple to understand but is it simple to get a robust and durable workflow in place?

We all understand the value of Unit Testing, but how come so few organisations maintain unit tests for their in-house applications? We can no longer pretend that unit testing is a universal panacea for ensuring less-buggy applications.
