I should have been more specific :) I was talking about either new products
or entirely new features for existing products. Generally, the model
supports starting at low fidelity to get initial reactions with minimal
investment and moving through to highest fidelity (actual product or
alpha/beta version) before release. The cycle also calls for a series of
session post-release to re-evaluate (both as a standalone product and
against competitors) before the next development cycle starts.
