The correct answer is A .
AgilePM supports progressive estimation , and relative estimation is one of the best ways to do that. It allows the Developers to provide useful estimates early without pretending to have a level of precision that is unrealistic at this stage.
Why A is correct:
Relative estimation is well suited to AgilePM because it supports early forecasting .
It accepts uncertainty while still giving the project enough information for planning.
Estimates can then be refined later as more detail emerges.
This fits AgilePM’s balance between:
planning and adaptability,
usefulness and realism,
and early direction without false precision.
Why the other options are incorrect:
B is incorrect because estimating everything in precise hours and days too early creates false certainty and is not consistent with AgilePM’s iterative approach.
C is weaker because although higher-priority work often gets more attention, AgilePM still needs a workable overall view of scope and effort. Ignoring lower-priority items entirely is not the best guidance.
D is incorrect because AgilePM does not say estimation is impossible in uncertain environments. It says estimation should be practical, transparent, and proportionate.
So the best answer is A .
