Interestingly I am in a position to revisit the evolution of one of the systems in the FEAST study. The key insight from FEAST was the idea of an "S-curve" where complexity overwhelms drive for features. Initial development progress is slow because the infrastructure and framework for the system is not in place, then comes rapid development then a slow down as complexity kicks in.
The reviewed system behaved like that in the study (I checked the data) and for a few years after. But then a period of explosive growth occurred, halted only by a strategic decision to move away from the platform for technology management (obsolescence of mainframes) reasons.
