How this system affects decisions

Treat research as a sequence of choices: check its building, Age, prerequisite, cost, and the units or economy affected. An upgrade is most valuable when it arrives before the army needs it and improves enough of the units already in production; researching every available technology is rarely the best use of a limited stockpile.
