Yes you have hit the nail on the head, this is exactly what I meant.

I believe there is no quick fix to this, due to the breadth and depth of
decision makers involved in these type of technology projects. However, if
there were some way of proving such best practice (to the decision makers)
then it may end up scaling to large projects. It would seem that large,
public failures are opportune times to position such alternatives.

In my experience I haven¹t seen Agile approaches used for custom software
development worth much more than $2m, in those cases the key was in the
customer having utmost confidence in the solution and development team.

I would be interested if yourself or others have anecdotes of Agile
applied to large, complex development projects for tailored software
solutions. We may be going a bit off-piste for xml-dev here so please keep
it relevant to the list if you do have feedback.
