The episode in question , "All Good Things" (TNG: S7E25) is actually based in an alternative universe. Warp factors above 10 do not exist according to 24th Century Warp Theory as "Warp Factor 10" is interpreted as "Infinite Velocity".

It is important to note the differences between the earlier Star Trek material and the later material. Many episodes in The Original Series quoted warp factors that were later 're-scaled' as the newer series (The Next Generation, Voyager, Enterprise) came into existence. This is covered in more detail on the Memory Alpha for Warp Factors.
