Challenge your assumptions on the cost of quality

The usual thinking is that the earlier your find a bug the cheaper it is to resolve, and that the cost of defect remediation increases exponentially over the product life cycle.

Don't buy that at face value.  

Architecture, the team's capability and the tools and systems the team use will all affect this model.  It's not infeasible that the cost of remediating a bug in production is less than avoiding it in requirements discovery.

In fact, why don't you start measuring this today?  how much time is spent on each aspect of the product delivery process, and what does each cost in terms of rework?
