snake-oil simplification
When someone oversimplifies a task in order to get your buy-in. This is something done typically by sales people in order to clinch a sale, or by software management in order to convince developers to assign small estimates to large and complicated tasks
That mgmt slide show was a total snake-oil simplification! When you think about it for a few minutes its clear that providing the functionality described will be a lot more complicated than just plugging component A into server B. Who agreed to the effort estimates on this anyway!?!? We're screwed man, we'll never make this date!
