The only software which doesn’t change is dead software.
Stopping software from changing is a fast way to kill it.
Treating software development as a temporary endeavour kills it.
Regarding software as temporary also means the teams which create it get regarded as temporary. Such teams get disbanded at “the end”. The developers scatter to the four winds and with them the shared understanding and knowledge of how the software works and how to change it gets lost.
Disbanding performing teams is worse than vandalism, I call it “corporate psychopathy”.
