I believe he means value engineer, par example:
TDO: "Why do we need 5 animatronics in this scene"
WDI: "To add to the Show"
TDO: "Who cares about Show?"
WDI: "Well there was a guy called Walt..."
TDO: "Who?"
Or this example...
WDI: We are going to make a great ride with lots of awesome AA figures
TDO: Sounds great! How much?
WDI: We are going to charge $50 million for those AA figures
TDO: That sounds a lot of money for 5 AA's
WDI: Yes we like to overcharge for every aspect of what we produce for the parks. Other companies can supply and build entire attarctions for this price, but we can't.
TDO: Well we can't pay that much, so we are going to have to trim the AA budget to $10 million
WDI: OK, well now you will just get one AA.
