I agreed with you all the way until the last part about symphony, that is how you lose the attention of managers and leader types. majority of software is not a symphony rather a race car held together by ziptie and ducktapes just well enough to give a feel of something big in behind the curtains.
this is especially true if you consider the incremental work projects take on. THAT incremental work IS forecast-able. problem is often all the information need to be able to make that forecast is not in one place & the discovery process is often left unaccounted accidentally or on purpose to commit to tighter deadlines. add to that changing requirements and you have the state of software estimation we are in.
