Yup. I would expect my guys to knock this out in a few weeks. (plus testing etc). Data Integration is our game (INFA). Manage, Analyze, Architect, Design, Build, Test, Deploy, Operate. It's called a methodology. When an employee leaves, the knowledge transfer burden falls to the vendor, not the customer. It's called an 'execution discount'.
Apparently there are a lot of IT guys here that also like to BBQ! :)
