Charles Moore definitely believes in modifying the original problem so that it fits forth while he modifies forth to fit the problem. I have used a similar approach when I needed to get a PoC out in 6 weeks, we made it, but not without drastically modifying "the spec". In one instance the PM wanted continuous queries over geospatial data, millions of points and arbitrary locations along with a time dimension. I changed the spec to use 3 buckets, near, medium and far. That feature took 2 hours, the continuous query itself would have taken weeks or longer. Successful projects have a malleability to them.
