In my experience, this may well indicate that someone up the food chain has some different ideas or vision about your project. Often consultants are brought in to recommend what upper management wants to happen, rather than come up with real findings. It saves them having to directly disagree with their own staff. In other words, "Look, these outside (unbiased!?) experts said we should do it this way instead." The problem is that they are often far from unbiased. One of my friends who has been a consultant to some pretty big players was often surprised at how often the 'results' were handed to him by the client after they did their analysis.
Hopefully, that isn't the situation here, but it isn't uncommon. It's something you should keep in mind.
